TD04 Vs Lateral MD304

[Scott.T]

Thought I'd post up a few piccies of my original TD04 (thats not been on the car for a few years) against the Lateral MD304 I purchased from Spooky.

I hope to get this on in a few weeks, and will post some pics of it against the VF28 that is coming of (and will be up for sale).

As you can can see from the pic the MD304 is lust a little bit ported to get a bigger wheels in.

It's spec is VF28 Exhaust side (for quick spool), ported with bigger Garrett wheel and larger wastegate button.
VF22 (Largest VF of the series) Compressor housing, ported with larger Garrett wheel.
Turbo Dynamics updated Actuator.

Not sure if it may be a MD308, as other images of MD304 I have found, the compressor wasn't ported quite so much.
Needless to say i won't be doing the jubilee clip up too tight as those side walls are quite thin.

looks like theres a crack on the md? penny flap upwards?

[Scott.T]

WOW... nice one Tone... eye's like a hawk there mate.

i have just popped the actuator rod off to open the pennie flap and your spot on. The crack goes right through.
looks like I need to PM Mr. Spooky.

GUTTED...as was dead chuffed to get a good quick spooling turbo with good power capabilities.

Will post a pic of crack soon as just of to get a chinese takaway.

Looks good Still like to have the vf off you just worrys me if it will push mine to far.We will have to have a chat soon

Stay and get it delivered from the Double Dragon.

sorry mate its quite common, i dout it will make any diffrence in boost control will it?

[Scott.T]

So glad I didn't fit this, thank god I was in the middle of dry-lining our utility room or it may well of been on.

Looked all over the outside of this when it arrived checking for cracks in the exhaust housing where it mounts on the flange and round the back of the compressor, where the TD05's normally crack.
Didn't think to check inside the back.

It will probably effect the spool, if you think what a crack in the up-pipe can do.
I also think the pennie valve isn't shutting flush due to there being a step in the flange due to the crack.

One thing is for sure, it's only going to get worse.

Anyhow, here's some more images of crack through exhaust housing.

Holly **** balls!!

Just to let people know, a full refund has been offered and rightly so!

Sorry again matey, i didn't get to see the tubby when it came off as it was all done at the garage!

Would have hated for you to have fitted this and been disappointed...

[Scott.T]

Cheers Matt,
Got your PM, I'm sure it will all get sorted one way or another.
Thanks

Cheers to Tone for spending his lunch break messing with this turbo.
We can now confrim the IHI P18 Exhaust housing will fit an from doing a Google tonight the larger P20 will also (but suffer a bit more lag), but both will require porting to match that of the MD304.

However, Tones spare VF24 P18 Housing also had the startings of a crack .....

So the hunt could be on for a housing.......

this might help

VF22
This turbo has the highest output potential of all of the IHI VF series turbos and is the best choice for those who are looking for loads of top end power. The top end power however, does not come without a cost. The VF22 spools significantly slower than the rest of the IHI models due to the larger P20 exhaust housing and is much less suited for daily driving than some of the other models. Although the largest VF series turbo, the VF22 is not quite optimal for stroked engines or those who wish to run more than 20PSI of boost.
VF23
This turbo is considered a great all-around turbo. Like the VF22 it utilizes the largest P20 exhaust housing. This housing is mated with a smaller compressor housing of the of the VF24. This turbo is considered optimal in applications with range from mild to slightly wild. It does not have the same top end power of the VF22, but spools up significantly quicker.
VF24
This turbo shares its compressor housing with the VF23 however, this housing is mated with a smaller (P18) exhaust side. The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group N rally cars.
VF28
This turbo came standard on the STi Version 5. In terms of overall size, it is smaller than the VF22, VF30 and VF34, and about same size as the VF23.
VF29
This Turbo is nearly identical to the VF24, with the same compressor and exhaust housings. However the compressor wheel in the VF29 is has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such this unit is typically chosen over the VF24.
VF30
The VF30 is commonly considered the best bang for the buck turbo in the IHI VF series line. A relatively new model the VF30 features the same exhaust housing as the VF24 but a larger compressor side similar to the VF22. The combination of these two parts results in increased output potential without the lag associated with the VF22. Although it doesn't offer the top end supremacy of the VF22, the VF30 is a great compromise between these unit and the quicker spooling models.
VF34
The VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30.
VF35
VF35 The VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY.
VF36
Roller bearing version of the twin scroll VF37, also has a titanium turbine and shaft for even quicker spool. Same compressor housing as VF30/34, however twin scroll P25 exhaust housing provides slightly better top end output due to reduced exhaust pulse interference. This turbo is good for 400HP and used on JDM STI Spec C from 2003 onwards.
VF37 (thrust bearing)
Enter the age of twin scroll IHI turbos. Same compressor housing as VF30/34, however has a new twin scroll P25 exhaust housing that provides slightly better top end output due to reduced exhaust pulse interference. Twin scroll also provides better spool up for improved low down response over the VF30/34. This turbo is good for 400HP and used on JDM STI from 2003 onwards.
VF38
Twin scroll turbo with titanium turbine and shaft. Smaller compressor housing than VF36/VF37 provides tremendous spool up capabilities but less top end than VF36/37. The spool capabilities of this turbo are demonstrated on the JDM Legacy GT, which reaches peak torque at 2400RPM.
VF39
Single scroll turbo used on USDM STI and latest 2.5L STIs released internationally. Smaller than VF30/VF34.
VF42
Exclusive turbo to the S203, S204 and RA-R models, this unit features a twin scroll design with a slightly larger compressor than the VF36/37 turbos and different turbine design (more blades). The VF42 is a roller-bearing turbo and is likely of similar size to the VF22 turbo, but with twin scroll exhaust housing for faster spool and superior top end performance due to reduced exhaust pulse interference.
