Fuel injectors...

I have a 1992 mitsubishi 3000gt vr-4 and I was wondering which fuel injector size I should go for. I was thinking about a 660, but would a 720 be too much? I need these to get my psi above 15. And also, what company would you recommend?

Are you upgrading your turbos, fuel pump, and getting an air/fuel ratio? Or are you just boosting over 15psi. Stock you can't go above 14.5 and even that you need a good aftermarket boost gauge. (also you'll need to upgrade your plastic y-pipe and this will blow off around 15psi.. You will hear a thump under hte hood and lose all power.)

But assuming you know all that. It depends what turbos you are getting. If you are staying with stock, and just upgrading fuel pump and such...I would go 440s. I'm getting 15G turbos and will probably get 550cc injectors. 660/720 are if you are going REALLY BIG. Don't get them otherwise as you will be dumping way too much fuel and running really rich.
I mean some more specifics would help..
What upgrades do you have/plan on doing?
What are your goals?

Also www.3sxperformance.com has some good deals, check them out. They only use parts good for our cars.

Yeah like he said, depends on your goals..

For instance if your keeping the stock turbos, I would go with 450cc injectors out of the eclipse/talon.. Those are cheap upgrades..

Otherwise tell us the psi you plan on running and turbo setup if your buying aftermarket turbos.. Plan on using a SAFC or another fuel controller? Fuel pump?
