As the topic says, what have those of you who ahve gone big power done for fuel requirements??

Fuel pump - use std and disable std relief valve in tank OR fit upraeted unit and use of adjustable fuel pressure regulator??

If adjustable fuel pressure regulator is used, a return fuel line has to be fitted.

Injectors - what cc and where from at real world prices??

Don't think that this has been covered at all.

Soooo many boosted cars and nobody with ideas.

The std injectors and fuel system is good for 220/230 hp at Toyota's lower fuel pressure.

So fit a uprated high capacity/high flow fuel pump with return line and a fuel pressure regulator with pressure bumped up to 45psi (std fuel pressure on Toyota's is 33psi).

Now thw std injectors should easily be capable of fueling for 300 hp.

Its ok then to stay with std fuel system and just go bigger on injectors?? and get a standalone ECU to sort it all out sparkystav?? A lot less work - perfect then. Where did you get your injectors from sparkystav?? Heard PowerEnterprise do a set that fits the 1G fuel rail - got any part numbers :D please. Any idea of cost??

I think its gonna be easier to fit a FPR, with uprated pump and return line with a hike in fuel pressure. And as an AEM will be fitted, the fueling will be well under control.

Easier than locating bigger injectors.

Maybe the std FPR in the tank can be modified to increase fuel pressure.
