87RX7TurboII

I have a Profec B Spec II set at 10PSI and when i step on the throttle the car spikes out to 13.6PSI and the throttle sticks when i let go of it and revs up to 6K RPM then lets go. How can i fix both problems of the creep and throttle sticking... I have a 3" Racing beat exhaust and street port motor and a air intake.

Anyone got exact settings for the Profec B to set it steady at 10PSI i dont know if its my settings that are wrong

port your turbo wg as it is very small and this is a very common problem with turboed rx7's even more so with the 86-88 models. as far as your throttle sticking make sure your thottle linkage is well lubricated and make sure the throttle cable isn't binding up anywhere.

For the throttle sticking.

Have you ported your throttle body, or removed the advanced warmup system?

nothing is ported whats the warmup system? where is it? on my throttle body i have a actuator that is controlled by a vacuum hose and it controlls the bottom flapper could that be the reason it stick so much? also im looking to get a Tubular manifold that will also work with some cheap ebay turbo meanwhile i want tog et the GT35R style turbo in about 2 months. Can someoen PM me a good tubular exhaust manifold to get currently or a setup? I have a 3 bolt downpipe but i dotn know where i can buy a V Band Adapter to it

why do all that if you could just go to the archive and look how to port the wg witch is fairly simple.

If you don't even know how to control boost..why would you get a bigger turbo? Boost controllers can only RAISE boost, you're wastegate is the only factor in LOWERING it.

The accelerated warmup system..crack open an FSM/WSM. It's a bit of thermowax on the rear of the throttle body, it limits you from going wide open throttle while the car is cold.

You're throttle body flaps are not controlled via vacuum, you need to take a closer look. Once again, try cracking open an FSM/WSM. Or remove the TB and play with it....

Lube you're pedal assembly, and make sure you're carpet isn't what is catching the pedal. Mine was

Read the manual.. If your boost is spiking then you need to lower your "start Boost" setting. If its creeping, then you need to adjust your "Duty cycle" setting.
