hey guys im currently running a b18 ls/vtec at 5 ps1 of boost with 450cc injectors tuned, but im running the stock fuel pump, is this bad? if i change it will it help at all?

 

Your tuner should have told you if your set up is getting lean. Chances are youre fine at 5 psi. The only reason you would want a new pump is if you want to run more boost. With your set up i'd get a walbro 255 and run 10psi, why only 5?

 

the REAL question, is 5psi on what turbo?


5psi on a T28 is going to be JUST alittle different then a GT4288R...

why dont people understand this?


Its less then 100$ for a walbro, get one.

 

I agree, they're cheap insurance..do it right the first time. If you can't afford to buy a walbro then you shouldn't turbo your car.

 

Yea I agree with you, but how many people do you know that runs a 42r at 5 psi... If your going to that extreme of a turbo you are not trying to make it streetable.

You can pretty much assume that he will be dealing with a relatively small turbo.
