Re: Thinking about turboing 98 750
I have been told (I dont know much about turbo workings) that running two base gaskets on the block will lower the stock compression ratio enough to run a turbo up to 8 - 10 psi.
You SHOULD invest in better rods, and maybe an adjustable cam sprockets so you can make up for the longer run from the crank to the cam (it will correct the cam timing).
I good shop you can get your parts from and have a great amount of know how is gsxrzone.com (APE Racing). They are big into drag bike motors.
