With the HP your pushing im sure your injectors are already maxed out. Ive heard the fuel pump can handle up to 550cc injectors.

I have a set of PnP 550's for sale soon, but you already have pigtails for RCs.

Remember the S/C that is on the 300swhp? He went with the 440cc injectors all the way to 29ish, and THEN he started to run lean. Dezod has said that the stock pump would be able to take 500whp, but at that rate another pump would already be used.

Okay, I stated, that I haven't proved this, that some shops that make turbo kits said so. If it isn't like that it's good to know. My Mistake. There, thanks.

This is all I could find, guess I was reading VERY WRONG.

We're looking at fuel pump upgrades. We're designing the new Dezod Alpha turbo kit on my tC so it's all out built motor/tranny/EMS stuff now.

Well I guess I was rigth. By the way, somebody told me that we could use the Supra fuel pump. He told me that it fit perfectly. Or you guys could do what I did with the Walbro 255.
