s14blitz

Hey everyone I hope you can explain some thecnical stuff to me.

I own a 1997 S14 blacktop SR20det. My question to you all is if it makes sense to change, injectors(550cc) and fuel pressure if I don't have an engine management system.

My goal is to be able to go up 16psi op boost without blowing up things.

My current mods are: blitz front mount intercooler
blitz downpipe
blitz blow off valve
Greddy profec b boost controller
blitz turbo timer
walbro fuel pump
hks spark plugs.

So can you tell me how the stock ecu will respond if I put 550cc injectors and an adjustable fuel pressure regulator? Will I be able to boost to 16psi relatively safe?

Until know I think the car will run to ridge with the possibilty of detonating.

Hope you can help me out!!

Greetz,

detonating comes from lack of fuel... or running lean... if you increase the injector size you will end up with running rich...

also you might not even need to increase your injectors too large... depends on the power lvl you are trying to reach...
