Fuel pressure regulator...?

[PuGZoR]

I have an internally stock AE101 4AGZE that I've turbo'd, and hope to be running around 15-16PSI. Will the stock fuel regulator on the AE101 fuel rail be good enough to handle the ~150-170KW (at the wheels, yo) that I'm expecting, or should I get a Sard/Malpassi regulator for my mofo?

Thanks.

I think the normal fuel pressure on most cars is about 40psi. Your question is, will your injectors flow enough? If not, I would be looking at getting different ones. I would think going to higher fuel pressure would be more of a band-aid than a propper solution. I may be wrong.

Oh yeah, stupid me forgot to add that I'm now running 440cc injectors and a Microtech LT10S.

Those injectors should be fine, but I'll let someone else confirm it.

7MGTE injectors??

they should be fine.. a mate has 440cc (stock 3SGTE ones) on the brink in a 3SGTE making pretty much spot on 300FWHP.. with a fuel reg, but peak pressure is set to 55psi

normal fuel pressure for one of those, depends on the ecu and tuner whether of not it grinades its self though..

Dunno what the injectors are from, they've got black sleeves though as opposed to the stock ones being that red/orange colour. So general concensus is that the stock FPR should be able to cope with the boost and injectors I intend on running?

a calculator BigT showed me hope that helps

by that a few more PSI and 280hp @ the flywheel should be ok

Im running stock injectors and regulator in mine. Good for 14psi and 160rwkw's of goodness.

5cc per hp is a pretty good rule-of-thumb.
So you have 440/5= 88hp per cylinder or 352hp at the crank available in terms of injector flow.
