The car looks fun as is. If you go wild tires and big bore then you have engine torque/super-wide tire grip and THE tranny problem.

Keep the 2.2L. It is already short stroke. Torque stays low off boost. This is a very light car, add the turbo and you will be surprised by it's performance.

Before there were "factory turbo motors" and "engines built to turbo specs" we put turbos on motors. Do that to this one.

Here is my formula:
Used K16 from 993/996, add W/G adjustment
CIS or EFI (if you want to spend a lot of money needlessly).
MSD with program feature.
Split Second 7th injector (programmable)
W/M injection
Hook up the pipes.
Drain oil back to chain or camshaft cover.
Install Boost, A/F ratio gages

Do not listen to all the B.S. about MAG crankcase, std. studs, iron cylinders and cast pistons. In 1970-1971 ALL 911 motors were exotic premium motors...still are. All these things are adequate at reasonable boost levels. Make 220-240HP and have a good time.
