Can anyone help please??? i've just brought a 95' plate wrx, the engines a non runner! it has a walbro fuel pump, hks induction kit, apexi ecu, and a full stainless steel exhaust.
My plan is to get a new block and heads, whilst keeping the original electrics etc, my question is will i need to retune the engine to the ecu? to get it to run right, my other question is with the modifications it has on it do i need to up rate anything else eg; the injectors etc; to prevent any further damage! could these modifications of been the reason the engine went in the first place? ( it overheated and lost compression on the o/s cylinder head) possible piston melt? Any info much appreciated!!!!!

 

your best bet depends on funds mate weather you get wrx or sti forged up.It is wise to up rate ur injectors and maf if you get wrx make sure u get the import not europe or uk hope it helps where you from mate

 

Cheers for that mate, i'm in gloucester! so the injectors need doing then!

 

if u put sti engine in its good to uprate the injectors if wrx just leave the same injectors in cus wrx are not as strong so if u uprate the injectors on 1 its going to do sum damage cuz the bhp will put it under straine with uprated injectors if that makes sense mate

 

iv got standerd wrx ijectors if u nead sum leave me a number and will sort somthink out iv got a sti block aswall but thats spun a bearing and smashed a piston so mite have a few bits if i can help out cheers dean

 

i dont think the injectors would be a problem because if you aint changing the turbo theres no point. there good for around 290bhp i think and you wont get much more
without a bigger turbo.

 

cool if you just changein the block and heads with wrx every think ells will be fine you dont nead to uprate anythink sti block and heads you can uprate for more bhp

 

Cheers for the messages! will let you know if interested in the injectors. :-)
