Can the stock injectors be used in a turbo kit that will only be producing 350whp?

 

Some say yeah, but Im at 305whp and my stock inj duty cycle is 90%+ at times, so I say no.

 

No

 

definitely NO.

 

It all has to do with how much of the duty cycle you're using on the injectors. The stock ones can only safely handle 300 or so, and that is sorta pushing it. You can do more hp on them, but you're playing with fire somewhat because if there ever is an instance where the car needs more fuel and the injector cannot produce enough fuel - you're going to have a bad time

The minimum you're going to need are some 440s or so, but the price difference between those and anything higher is negligible. They're kind of one of those grin and bear it mods that you just have to buy for safety.

 

how big are the stock injectors??

 

I've got some 578's practically brand new if you're interested and they would be perfect for the power you want. PM me for more details.

 

either 360 or 375 I believe

 

Stock injectors are 360cc and I would not attempt to run more than 300whp on them. Don't cheat and run excessively high fuel pressure.

 

750's are very good all purpose size injectors
