More BHP!!!
 

Anybody got any ideas on the best way to go about pushing my impreza terzo to around 330hp+ without gong toooo mad on the money. I have been loking at a TD05H 16G turbo which claims to be able to push the car to around 330hp, but im sure there must be more things i need to change. Also does anyone know what my engine is capable of without having to change the conrods and pistons?? My engine is a EJ20...

Any bit of advise would be greatful....

walbro 255 pump
fuel pressure reg
3 port boost solinoid
full systum exhaust (de-cat)
ported headers
440cc injectors
td05 16g or a vf34
and a remap/aftermarket ecu (scott on here)

Cheers mate.......
Would i blow the engine if i didnt purchase the ported headers?

Re: More BHP!!!
 

nope most important thing is a re-map.

headers just improve spool up

Cheers mate, much appreciated, im looking at a td05 h 16g turbo now and i just brought the fuel pump, looking into the rest now.

Thanks again... :D

MY98 will need an Apexi PFC for best results per £.
May be worth sourcing an STi Orange label MAF off Ebay as the stock MAF is a bit limitting on airflow. Plus the Apexi will be scaled for the STi MAF (not an issue to rescale though).

440's even at higher pressure are going to be running very high IDC.

Mine run 97% at ~320BHP at 3bar idle pressure. Could run them at 3.2bar to give a little more headroom, but don't get much of a chance to remap me own car to suite the extra 0.2bar pressure. So left as is for now.....running 1.45bar peak, but little ol' VF28 drops to 1.1 by redline.

Other then that, what Tone say's is about right
