Hey all, quick question. Im sure Ill get diff opinions but Id like to see what everyone thinks. Ive heard/thought about getting bigger injectors, not sure what size though. But some people say there not needed and stock injectors (530cc?), are just fine. They add the only time really neccesary to get bigger injectors is when you upgrade your turbo. Meaning no matter what mods, if I keep the stock turbo then the stock injectors are fine. And I really dont want to get them unless I need them and they would make a big diff, since they do cost a nice chunk of change. Anyway thats it, and You can see my mods below. Any thoughts??? Thanks!!!

 

The stock injectors are 560cc. With your mods I would suggest you get the BR680 injectors since you have the fuel pump. It is a safety thing as people have seen the stock injectors sometimes not keep up.

 

I would think that the stock injectors would handle the power.... 550/560 whichever they are should be plenty of flow for 350whp. A fuel pump and regulator would prob be needed, as well as some new fuel maps but running 100 octane or a water, alky, or propane injection system would for sure be able to handle that power goal. My eclipse would handle a EVO III turbo on the stock injectors, fuel pump and regulator with no AFC and only the addition of race fuel. Timing was fine and single counts of knock was found only in the upper RPM all running at 15psi. Turbo was capable of 20psi but for that I would have needed some fuel modifications.

just my 2 cents
