Ok I am expecting the fuel kit from rx7store soon. I purchases the Extreme Fuel System which has 1600's. I have a supra tt pump in my car and still non-seq. Whats the best fuel pressure to start with and what can the tt pump handle?

You'll want to run about stock pressure...36-38 psi at 0 vacuum (not idle!).

So basically start the car and let it idle and then pull the vacuum line off of the fuel pressure regulator and adjust the base pressure to 36-38 psi and the plug the vacuum line back on the regulator.

Thanks guys, so that pump is fine?

Assuming your wiring is in good condition, you should be good for about 415-420 rwhp on pump gas, with that pump.
