From people I've talked to you can use the motor stock as long as you keep it under 10psi. Not sure the accuracy of this, but it seemed to be a fairly consistent opinion.

 

o ok..cool thanks.

 

And the Carb will have to be prepped for a turbo. or buy a different one.

 

Hey get a 650 holley marine carb and dont go pass 7 psi. I will recomend you to go and rebuild the engine. Street port and half brigde. If you have any ??? let me now. and what kind a turbo you are using. make sure you get a FI fuel pump and a regulator with a return.

It depends a lot on the setup that you will be running. There are many variables that will affect the safe level of boost. Compression ratio is just one of them. 6-7psi is a relatively safe level assuming you are fairly diligent with controlling A/F mixture, intake charge temps, and timing.

 

o ok...wat would b a safe setup...i saw ur red rx7 before u changed it..thats how i want to set my car up

 

best person to talk to about this is robert from rotaryshack he has a 12a turbo with over 630hp at the wheel and his running high boost , his number is 818 693-1031 give him a call.
