Fuel pump question

[Schassis707]

I was wondering if a walbro 255 would work on a ka24de that only has intake and exhaust. I plan on doing the 248/232 cam upgrade as soon as I smog my car. And also if it would work will I be running too rich and have to use a adjustable fpr?

Thanks

No, you shouldnt have to use a adjutable FPR. Your only gonn aneed one of those if you get bigger injectors. So your stock FPR should be jsut fine, Unless its Bad.

Warbro flows more fuel at a higher pressure. It will eventually kill the stock FPR as it tries to bypass all the extra fuel and pressure.
