Well, I've started down that slippery slope.
I'm in the early stages of rebuilding what will eventually become an ITS RX-7. The car is a 90 TII chassis but with a complete drivetrain and suspension from a 91 GXL. I currently have a rolling shell without engine or tranny installed. The original 91 engine blew a coolant seal and I am beginning the rebuild process.
With that in mind, I had a couple questions about what the rest of the ITS crowd is running in terms of engine modifications:
1) The OMP - keep it or toss it entirely and rely on pre-mix? If so, how do you keep the S5 ECU from whining and going into limp mode?
2) 5th/6th Ports Actuators - is the general concensus to remove these and just suffer the low-end power loss? If you keep them, how do you provide the air to actuate them?
Any other bits of wisdom you can toss my way would be greatly appreciated.
Thanks,
