1jz Billet 6262 turbo...FUEL SYSTEM UPGRADES???

[IndigoMKII]

My SP6265 is getting 1000 cc injectors (ID, Injector Dynamics), but I am also using a standalone (HKS Fcon Vpro 3.3). The ID injectors are a bit more expensive, but they have the ability to cycle down so you don't have to worry about overfeeding. I have the Denso MKIV fuel pump in my tank, so I will see if it feeds enough. (no wire modifications)

Mind you.. im running 7M, but still don't expect anything to fit as you think it will. I keep forgetting that installing a modification is just that... a modification. It means adjustments to accommodate.

With that setup, I think anything over 18 PSI and you're going to be at the limit of the pump. Then again, 18 PSI will probably be close to 500 rwhp.

Yes, my goal is to setup for 425'ish with a 475-500 max scramble button. For my summer cruising 400 hp will be overkill.

This all changes if I ever start doing quarter mile track runs... lol.
It's being setup more for street. Having experienced 380 torque at the wheels, should be plenty for my needs.

550+ just seems a little insane for street/highway and I have a heavy foot so I'm limiting myself.

Anybody running this kit have power figures?

I'm running a 1jz, stock cams, ms3pro, 800cc sard, 3.5" catback, 320lph aem fuel pump, 2.75" in/out IC, 2.5" cold/hot side and this DM 6262 turbo kit.

I have turned the boost up (18psi) and I am disapointed with the performance. The car is tuned right, new plugs, no misfire and no boostleak (verified with a tester up to 25psi). I was expecting more from it.

possible timing map issue? are you running knock sensors?

With all respect, how can you tell if a tune is right, when you dont have numbers from a Dyno?
A street-tune will never be more than a "decent tune". Get it to the dyno - It's money well spent.

You need atleast 750cc injectors to really use the 6262. If not just go for 1000cc high impedence and big fuel pump or twin walbros and be done. If you dont have power goal well over 500whp, then the 6262 is too big a turbo for your needs.
