How much is too much boost for stock injectors?

[Deathmug]

Hey guys.
I just wanted to get a few of your opinions out there on this.

I just had my motor rebuilt, & new turbo/headers. I’m going to get a FMIC & new fuel pump/injectors soon.
I was wondering based on my mods, what is the safest amount of boost I can run w/o potentially causing damage to my engine.

Thanks alot! You guys have always been a big help to me.

I would not go anything above 14 psi until you get a pump then you will be ok at 16 but thats it (on 93 oct) . Its tuff not to push that 50 trim but you have to do what you have.

like everything else, check the logger.. you are running to much when you are having timing pulled and the injector pulsewidth is in the 90+% range

Yeah.. I havent got a logger right now. I was planning on getting a Greddy profect E when I get the injectors.

Any sized turbo bigger than stock calls for new injectors and fuel pump. Oh, and dont forget the AFPR, or skimp, whichever you choose to heed to..

Alright. I was thinking about 690s for injectors? What do you guys think?

Each car is different.

I have pushed my stock fuel system to the limit with 17PSI on the EVO III right now.

I have a Megasquirt standlone installed so I think that helps since I can completelly cusotmize my fuel and timing maps.

Going to throw on the fuel pump and FPR and see if we can't hit 20PSI safelly.
