Worzels 2.5 shopping list
 

Right boys and girls.

As you are probably aware by now, I am just about to go 2.5 due to my engine having a poo and burying itself on the run down to Germany.

I have purchased a 2.5 lump from Nige (cheers mate :five: ) and until he is back from sunning himself in much warmer climbs, I am not sure what the lump comes with apart from uprated bearings I believe?

To that end, I am looking to get a shopping list put together for the build. I have just about scraped together £3000.00 to do this.

I am going to see the garage tomorrow to get some ball park costs from them, so that will give me an idea of what I might have left.

The one thing to take into mind is the fact I am NOT looking for massive power figures, 400bhp is NOT what I'm looking to break or even achieve. If I got 370 / 380bhp I would be happy as larry. So, I am sticking with the Vf34 turbo that I already have, as that is more than adequate. To that end, front mount is another thing I don't want to do either.

So what do I NEED for this build?

The first thing that's been spoken about is Forged Pistons, as Scott said, this might already have them, but we will find out when Nige returns. If it hasn't got them, we'll start there I suppose.

So....... the list starts. Please add your recommendations to the list. Makes, details, prices if possible etc etc.

Cheers in advance

Worzel

Re: Worzels 2.5 shopping list
 

Are you going for a front mount?

Or is the the top mount adequate for what you want?

Re: Worzels 2.5 shopping list
 

you need to decide on a figure now however high or low it may be, will really vary on what you will need, i drew the line at 450 max and tried to build to that, if your not careful your have some bits that are overkill and some out of a cracker

Re: Worzels 2.5 shopping list
 

worzels quote= front mount is another thing I don't want to do either.

worz doesnt what to chop his front about i think but i can see what your saying 'E', will the sti top mount be man enough!

Re: Worzels 2.5 shopping list
 

think im right in sayin that 400 is the very max

Re: Worzels 2.5 shopping list
 

I'm not looking to go over 400bhp so top mount will be fine.

All im looking to get is 370 / 380bhp, not after massive figures at all. :doubleup:

Re: Worzels 2.5 shopping list
 

Ver 7 was the last proper forged pistons , even says it in the link posted by scoott ;)
As said before forge pistons ,as lots have had probs over 350 ,but like myself others have not at 400 . its up to you and as i see it for just the cost of pistons at this stage it would be cheaper than having the engine taken back out stripped and borred later on !

Re: Worzels 2.5 shopping list
 

Exactly that CJ. I don't ever want to be taking this apart again for sure.

So First proper thing on the list is Forged rods and pistons.

Any recommendations people?

Re: Worzels 2.5 shopping list
 

You should be fine on pinks till 410/420bhp with a good fuel reg like fuel lab or sx :doubleup:

Re: Worzels 2.5 shopping list
 

360-380 on the 2.5 and the VF35 will be possible on the TMIC.
Forged pistons IMHO are overkill on that engine, considering the required power and with the relativley small VF35 Turbo.

When you consider what you are paying for the short engine compared to £575+VAT for the pistons it's making it a much more expensive build.
Plus you need to factor in that Vince will need to strip the block to replace the pistons, which may already be forged (need to check with Nige and the guy that built it, as he will be able to confirm).
Plus if you are cracking open the block again for the forged pistons then why not go for new rods aswell.....

Just don't get carried away if all you want is 380BHP.
A few people have gone 400-450BHP and wished they had stayed with a more practical and driveable 350BHP.

Get confirmation from Nige on the build then speak to Mark at Lateral expaining your requirements.
He's a practical guy and won't guide you down the route which best lines his pockets, or a route dictated by forum junkies that know all the names of the latest trick bits that score points on the pub-bull-o-meter.

Mark will also confirm that the STi Pinks are up to the job, expecially with a £200 Fuelab Pressure Reg, as I had exact the same conversation with him a few weeks back regarding Nige's car running the much bigger 20G.

As CJ and myself will tell you, you don't need to go mad to get good power.
I'm running 120BHP over stock with what amounts to a relativley small turbo, tmic, decat and a remap. I expect to get to 350BHP if I change the turbo and mess with the fuelling.

P.S You need to be very carefull with the choice of forged pistons and there size. Forged do have a tendancy to rattle like bucket of pebbles until the engine is warm. Sounding like very bad piston slap (which is actually what it is, until they have warmed and expanded).
I have heard some real bad cases and it would P-I-S-S me right off after spending all that dosh. I would want a garuntee that this wasn't going to happen, and it can be made so if matched and chosen wisley.

Re: Worzels 2.5 shopping list
 

When speaking to mark he as always said to me to change the pistons to forged . Think steve is thinking about more power possible next year ;)

From a vid i saw of someone changing pistons on a scoob engine its done with out splitting the block , will have a look for it .

Re: Worzels 2.5 shopping list
 

The pistons that rattle are normally othersized items ive found, 2.1 engines are normally very loud on start up

Re: Worzels 2.5 shopping list
 

Thanks for all of your input, it's fantastic help guys. :10:

I think as you say Scott, waiting for Nige to get back is important.

I do want to do it right though, the last thing I want to do is go back in to do anything. I would rather pay the money now and get good forged products and have the scope to do more in the future possibly.

In a years time, I might want to go front mount for instance with a bigger turbo. At this time, I don't. :D

But I also said I wasn't going to go 2.5 and have. :roll:

Re: Worzels 2.5 shopping list
 

got weiseco's in my 2.5 which are meant to be really noisey from cold, well, not really no different to any cold engine IMO, and its gone after bout a min anyway, dont need to split the block, took me bout an hour to change them and thats only cause i kept dropping the clips inside the block (no sump so ok) was assured by AndyF that standard 2.5 rods and bearings are good to about 480 ish as long as you keep the 7k rev limit for the rods, but with the right turbo and torque from the 2.5 that shouldnt be a problem

Re: Worzels 2.5 shopping list
 

my advice steve, set your self a target, and keep to it. from what i have understood standard ej257 rods and pistons are fine for 400bhp so leave them if thats your limit.
if you do get pistons i would let the engine builder source them i would recomend pennin subaru (chy) he is amazing! easy guy to talk to,he will explane things nice and easy and work with your budget.

you will need if a bare engine
oil modine+filter
oil pump
cambelt+tensoner/guides if ness
gasket set
head gaskets (1.6mm)
head bolts uprated (APR)
oil + antifreeze

also worth looking at the clutch wile its all apart.

also if you plan on useing your 2.0 heads you will need to have the heads mechend to suit the combustion chamber of the 2.5 bore.

(dont full in the trap of while that is being done i will do that and this and them ect as it gets very costly very quick!)


good luck!

Re: Worzels 2.5 shopping list
 

Brilliant stuff guys. The advice is priceless.

I am 99% certain that I dont want to go over 400bhp.

My only fear is, if in 18 months time or so, I then decide to push it a little further I will be swearing at myself for not doing what I could now. It's a real bugger to be honest.

I also know that going over the magic 400bhp brings problems that someone with my VERY limited mechanical knowledge will struggle to comprehend and be able to cope with.

Putting that last bit in writing really has just brought it home a little bit :shock: I am venturing into very uncharted waters for me, if I try to go big just for the sake of it. I think I have maybe been eating too much cheese late at night and dreaming too much. The decision is made. Once and for final.

I will be staying UNDER 400bhp, as per my original statement. 370 / 380 + good torque figures will do me very nicely thank you. The one thing I do want to do though is make it as bullet proof as possible. So people, please guide me as to the bits I need for a bullet proof 2.5 with the figures I just quoted.

Many many thanks guys! :doubleup: :doubleup: :doubleup:

Re: Worzels 2.5 shopping list
 

pistons are a must ring and speak to mark :doubleup:

Re: Worzels 2.5 shopping list
 

Agreed :doubleup:

Re: Worzels 2.5 shopping list
 

turbo wise td05 20g are amazing on a 2.5. :10:

Re: Worzels 2.5 shopping list
 

A concern I have is that you have doen 2 sets of big ends.
It's a Bob map so should be pretty safe, so you have to ask the question as to why.

You don't want to be doing it again if you can help it, but very difficult to tell if anything on the car may be causing it i.e MAF, Cam or Crank sensors.

Re: Worzels 2.5 shopping list
 

I went in to see Vince yesterday. He is not convinced that it is the big end gone.

I think someone said it when we pulled over too, but he thinks it might be a tappit problem (forgive the spelling if it's wrong), he said that he started it up and left it running for a while and the noise started to get less and less. He started when I was there yesterday and it sounded better than it did by a long way.

Whichever way it goes, I want to carry on with the project now.

How could I find out if it were any of the things you mentioned Scott. I have to admit the first one might have been my fault :oops: , but the second one was definitely not, never been into the red with it, warning set at 6200, all the fluids were at good levels, just had a service, and I didn't really go nuts on the drive down. I had a couple of small blats in it but nothing close to the red, the quickest I went was 140 on the de-restricted section and that was one up. Martyn had 150 3 up, Big E had 155 4up.

In the words of Toyah Wilcox...... It'th a mysthhhhawee!

Re: Worzels 2.5 shopping list
 

I would wait until Vince has had a good look before you jump to too many rash desicions.

It may be tappets or, as mentioned out in germany, it may be the cam belt tension has gone soft.
this makes a nasty knock as the plunger bounces of it's resting point due to the self priming plunger oil seal failing.

Mine done this a while back and would give a nasty knock noise on start up as it bounced.
Vince swapped it for a new one that I provided when I had the belt done.

I have another new one on the shelf ready to fit when the belt next gets changed as they can often fail after a cam belt change. The plubger has to be compressed and a pin insterted to old it, then when re-fitted the pin is removed to allow the plunger to reposition itself. if not done slowley and vertically the pil seal can be damaged and then after a while give the above symptons.

it could be as cheap as £160 for a new tensioner plus labour to fit new belt and/or recheck belt has not jumped a tooth.
Vince has also found in the past broken cambelt pullies or guides that also sound like big end knock.

Re: Worzels 2.5 shopping list
 

Heres hoping then!

Might be getting a refund from Nige! :fight: :whistle:

Re: Worzels 2.5 shopping list
 

If you are continuing with the build, and may be persuaded to go above 400, bear in mind that the fasteners supplied with the "Wagon Conversion Kit" will need uprating, as the boffins have found that the conversion unit will seperate from the main body of the vehicle when pushing upwards of 400 bhp.

Actually. :wave: :wave: :rofl:

Well according to my sat nav. :nod:

Sat Nav is pretty acurate then as Speed Limiter Fuel Cut on the WR1 Map kicks in at 158mph then comes off at 155mph.

Re: Worzels 2.5 shopping list
 

Def sounded ends to me.
Happy days if it is not mate :doubleup:

Re: Worzels 2.5 shopping list
 

I can only hope :doubleup:

If it's not ends and the repair is cheaper than the previous expected (which it bleedin ought to be) then the brake upgrade will be back on and maybe 3" full decat and remap.

If the ends are fooked, then ithe 2.5 project is all systems go. With forged rods and pistons (Overkill, yes more than likely but safe as houses) new injectors, maybe a better turbo & maybe 3" full decat. Then a map tweek.

Either way I'm out of pocket! :shock: :boom:

Re: Worzels 2.5 shopping list
 

hello did you manage to get your car sorted? I have just had the same problem but mine is defo the big ends as the engine is now lying in pieces in the garage!! Just trying to cost out what to do with it now?? :doubledown: :doubledown:

Re: Worzels 2.5 shopping list
 

You can have your money back mate not a problem. No matter what the outcome is Steve i would still have the 2.5 convertion. On some of the vid's Joe took at the ring you can see me gaining & passing 911's i made mincemeet of M3's before & after 100mph the torque factor is unreal & remmember Scott had to wind it back as i maxed out the bloody pinks. Mine is an oe 2.5 STI bottom end more than happy running 400bhp reliable & that engine was bought from Mark @ Latterall for more than double the price i was charging your good self. The engine you have bought from me is a semi closed deck bock with A.R.P race bearings. The guy who built this short block has built many 2.5's dazdavies he is renowned for his builds. Up to 400bhp with oe pistons not a problem. If it was i would have put forged pistons in mine :doh: . Daz has even run one producing 450bhp + for over two years on oe pistons with no probs & it was run hard. If you intend to keep your oe turbo you wont need forged. If you intend to go 20g or similar then you will end up with a big grin on your face mate. Have a chat with Tony he knows of daz & will put you right otherwise overkill will empty your pockets. P.S your oe STI top mount is good for 400bhp + A.F said so.

Re: Worzels 2.5 shopping list
 

Whats the news mate?

Re: Worzels 2.5 shopping list
 

Dyney got 400bhp tuesday on a newage WRX top mount and 411lbs on a hot day so would think its possible to see 420 to 430 on a sti one with agood mapp :doubleup:
And that was at niges fav rollers :D

Re: Worzels 2.5 shopping list
 

Quote from DazDavies re : Big End Failure

"Most often cause of bearing failure is oil starvation usually caused by the standard OEM Oil pump pressure relief valve sticking. This is because the piston on the oil pump has a 10mm groove in and can become prone to foriegn debris.

One of the best ways to prevent this is to run the modified oil pump from RCMS this has the piston in the pump replaced for a smooth non grooved item.

I had bottom end failure without one an have never had it with one. This is with 4 different scoobies and about 100K miles "

"Det will destroy pistons result in noticeable loss of power long before bearings get damaged. I had an engine failure due to severe det. One piston and bore got wrecked. The bearings were not that old and damned expensive (RCMS WRC items) so I reused them on the rebuild. They have been in the engine since and are still going strong.

If bearings are damaged and pistons are OK the cause of bearing failure will NOT be detonation! "

Re: Worzels 2.5 shopping list
 

No news yet. I think Nige has suffered Vinces "relaxed" timings too and knows what I'm going through :lol:

If it was my daily drive I would be doing my crunchies!

Hopefully, when I call him tomorrow he will have stripped it down and will be able to give me the news.

I have to admit, having so much time to think about it (which is getting expensive :roll: ) I might as well go for it no matter what. I keep thinking back to the drive home from Adenau with Nige, the night you lads stayed out all night. His car felt so bloody sorted it was untrue, that grunt and feel with the way my car is set up with suspension will be pretty bloody good.

Nige, are you around on Saturday morning? I want to pop down and pay the balance of the engine.

Here we go boys, another 2.5 on the way.

Can someone just tell Vince that japbash is coming soon :whistle:

Re: Worzels 2.5 shopping list
 

Scott, that's an interesting read.

What sort of money are we talking for said pump?

Re: Worzels 2.5 shopping list
 

Nige's car felt sorted on the way there with 5 of us in it, pulling like a train :10: :doubleup: :doubleup:

Re: Worzels 2.5 shopping list
 

Re: Worzels 2.5 shopping list
 

I have the RCM pump + RCM head gaskets 1.6mm. All top gear. :doubleup:

Thats a no brainer then. Another thing to add to the list :doubleup:

Re: Worzels 2.5 shopping list
 

So the list so far:

RCM Oil Pump
RCM Gaskets
Forged Pistons
650 Injectors
TD05 20g Turbo

Re: Worzels 2.5 shopping list
 

a must and would get penine to do the engine as he has a secret that is keeping him ahead of the others, plus his very well priced
Speak to dyney shy has just done his and think tony is getting them to do his and mine will be going to him when i get a block have avacs and high flow pump now :doubleup:

Re: Worzels 2.5 shopping list
 

If funds allow I will be going 3" decat :nod:

Re: Worzels 2.5 shopping list
 

steve
i have some bitz coming off my car very soon to save you some money (injectors 650 pe, exhaust, boost controller.)
i would recommend the,
rcm pump
cosworth rods, pistons
cosworth gaskets

if staying below 400 3" system will be pointless now (i have one you can buy)
i have heard of cars running over 450 on oe topmount (newage)

Re: Worzels 2.5 shopping list
 

Cheers Steve.

I will have some bits from you for sure mate.

You have pm :doubleup:

Re: Worzels 2.5 shopping list
 

Any news ? :whistle:

No... None........... getting a bit peed off now! :waiting: :waiting: :waiting: :waiting: :waiting:

Re: Worzels 2.5 shopping list
 

I am not pissed off really, but I do wish he'd get cracking a bit. I'm lucky I've got the second car really. And in fairness I did mention that fact and said I wasn't busting a gut to get it back, so he has probably used that comment to his advantage, as would I.

I wouldn't pull it from him after seeing and feeling the job he's done with Niges.

He explained the other day that he has been innundated with work and had some mares. And that he would definately get my engine out by the end of the week. I did explain that I need to know whats what asap just so that I can order the bit's I need and then arrange the mapping (that's the crucial one really). Lets hope it all comes together soon. I'm sure it will.

Love and peace my bro's :doubleup:

Re: Worzels 2.5 shopping list
 

Is that this week or next just so its clear ?

Re: Worzels 2.5 shopping list
 

He was looking to have it out by end of play today, so hopefully can get the info on Monday.

Re: Worzels 2.5 shopping list
 

sounds good and hope it all goes well :doubleup:

Re: Worzels 2.5 shopping list
 

Just spoken with Vince, we are rocking and rolling now. Going down there next week with the shopping list to arrange for the parts.

Nige

I will get this looked into. This seems to be happening a bit too regularly for my liking. Any removals should go through proper channels, through the "Cemetry" section which only mods and admin can see.

I will get the team on it and get to the bottom of this.

What happened then Wez?

Re: Worzels 2.5 shopping list
 

Went in for a service all the oils etc and a set of braided brake lines.All went well with the service but when Vince fitted the lines(last one as well) it had a split in it :doubledown: I got these from Japan so no come back it has left the car with 3 braided brake lines and one standard.I have ordered a set of Hel's now(as i do not trust the other lines) so saving £20 has now cost me £50 extra you live and learn :(

Thats a bugger mate.

Gave Vince my shopping list today! GULP :shock:

I am going to get it done once and properly though, thats the way to look at it.

Re: Worzels 2.5 shopping list
 

That lovely fresh built bottom end has to be split. With the rod'& pistons your useing it should be very strong. :doubleup: On the downside it will empty your pocket :doubledown: On the plus side it will go like hot **** off a shovel. :doubleup: Oi secret sam what have you done on the rear suspention?

What rods & pistons have you gone for ?

Re: Worzels 2.5 shopping list
 

I dont just mean the Cusco's. There are other trick bit's on the back end Sssshh. I wont let you secret's out mate :whistle: Would of been good to see it going around the ring with that set up. :doubleup:

Re: Worzels 2.5 shopping list
 

Cheers mate. It is a good set up for sure. It felt absolutely planted.

I have been looking at turbo's on the Andy Forrest Site. I am torn between the TD05 20g and this:

Re: Worzels 2.5 shopping list
 

Scogsy on Surrey had to send his AF20G back twice last year after it failed

Came back in a certain ****e ebay sellers box :whistle:

Re: Worzels 2.5 shopping list
 

I have had no issues with my 20g i bought from Scooby clinic . I think Anger has tried the 20g in the past. Worzel have a chat with Anger about the Md / turbo's. There more money & may suite your engine build as your's will take more power. :doubleup:

Re: Worzels 2.5 shopping list
 

running the AFP5-20 would be a good thing running a larger turbo than you need, It means u have more air than u need, which means u can be more conservative on the timing,and also your not trying to get every last horse out of a limited amount of air, u can just throw more air at the problem, which means overall it should prove more reliable. and also if engine is future proof you can just wind it up a notch
only issuse is lagg :whistle:

imo if funds alow md321T. on a 2.5 is a wepon!!

Re: Worzels 2.5 shopping list
 

Cheers for the input guys! :doubleup:

I have thought about the MD321 :norty:

Re: Worzels 2.5 shopping list
 

Then you start looking elsewhere and confuse yourself even more! :lol:

Help!!!

Just to reiterate my plans, I am staying topmount, I am putting in the following: forged pistons and rods (overkill on the rods I know, but don't want to go back in there EVER again!) 650 injectors, RCM uprated oil pump / oil cooling / gaskets.

Things to be confirmed: Head porting (dependant on RCM advice), Turbo (need your help guys PLEASE!!)

One other thing I have heard mentioned, is something that Granby has for sale, a winged sump! Worth getting? Please advise again guys.

My target is a rock solid 400bhp, not after big gains as I said when this all started. I don't want to go front mount. Just reliable, bullet proof 400bhp all day!

With that in mind, am I going overboard with the turbo? Should I just go 20g? Below is another screen shot from scooby clinic with many choices. I can't thank you all enough for the advice, it really is very helpful. Thanks to you all :doubleup:

[img]http://i178.photobucket.com/albums/w266/worzelg/Turbos.jpg[/img]

Re: Worzels 2.5 shopping list
 

head porting is a bit ott for 380-400 imo

Re: Worzels 2.5 shopping list
 

Thats what I was told elsewhere too.

Thanks for the back up on that one Tone. I reckon I can safely remove that expense from the list :doubleup: Which means I might be able to afford my defi's now.

Anybody know of any for sale before I start hunting? :whistle:

Re: Worzels 2.5 shopping list
 

If you can afford it Id go md321t or t+
Grandbys sump is an arc and they dont fit very well with standard headers or the laterial ones speaking to dyney about it .
20g will give you 400 but not in the same way a md321t or t+ will , if your doing it once id go t or t+ and some laterial headers with the venturi
Thats what i'd do from asking around .
On the rods and pistons i was asking as i now have a 2.5 block and thinking of a bit of discount on two sets !
Already got apr head bolts and rcm oil pump and a oil baffle .
Let us know !
Also laterial will turn your pinks into 850's for £150 +vat

Andy Forrest's is a 20G, just with his own branding and fetling.
20G will be a good choice on the TMIC, MD321 a better one.

I'm not 100% up on the compressor maps for the 2 turbo's but assume the MD321 is larger.
The TMIC flow and cooling efficiency is better suited to the slightly larger turbo as you can run less pressure for the same HP, due to the greater airflow from the larger unit.

Too much pressure on the STi TMIC will split/blow the intercooler at the crimpings.

Both turbos will have a good resale value if you decide to move on at any point in the future.

Sump is overkill imho, if it were a 100% track tool doing alot of track work then maybe a consideration.

Harvey Smith also supplies 20G's for around £750.

Re: Worzels 2.5 shopping list
 

Have you looked at the Garrett's on the RCM site......just to throw a few more into the mix...

Re: Worzels 2.5 shopping list
 

Yes I have mate :shock:

It is the one bit of kit I want to get right. And the MD 321 T seems to be the turbo of choice so far so I can't ignore it.

What of the Garrett ones would be the right one? Open to suggestions on this.

I have got a week or so to choose the right one, so happy to mull it over in here :nod:

Thanks again for the input guys. It is good to have the help :yeah:

Re: Worzels 2.5 shopping list
 

Im fitting my MD321T tomorrow weather permitting

Then its remap time on wednesday :doubleup:

Re: Worzels 2.5 shopping list
 

Looking forward to seeing your results

Re: Worzels 2.5 shopping list
 

What did you pay for yours mate and where from?

I have just saved a couple of hundred pounds on my defi's (Thanks Martyn :doubleup: ) so I reckon I might as well get the best turbo I can :nod:

Re: Worzels 2.5 shopping list
 

I would just talk to Ollie at RCM and tell him your thoughts to compare Garrett to MD321, then do the same with Mark at Lateral.

Are you getting the heads matched to the 2.5 block ?
