hmmmmmmm

 

Carl Davey, specialist Subaru Impreza parts supply to put the larger injectors in and yes they are different colours

price wise about £400 ish new depenmds where you buy them from really.

 

ok cheers 4 that is all easy 2 fit and how much are the injectors them selves thanks again mate

 

dont fit em yourself unless you are very competent as (and i will admit to it) i blew a large hole in the engine block when changine mine and now i am spending god nows how much now on a closed deck rebuild for more power

 

why did it do that ?its pretty easy 2 fit iv heard from a mate today

 

air got into the fuel line and then let fuel drip into one of the front bank of cylinders. once put back together started the engine and turned over with resistance then a loud knocking noise and it put a piston rod through the top of the block. basically vapour compresses but liquid doesnt so the fuel couldnt get out the cylinder and so jammed the engine and the weakest thing to give, did.
now building a 400bhp ish engine with the capability of pushing 600ish once run in properly and when i change the turbo and management. just gonna ease it in which is why is running low bhp to start.
