How are you going to use your car or what are your goals?

Throttle response and drivability over power or big power?

A great build is 8/1 pistons, ports, .8 bar boost, 964 cams, and GT35 turbo, on EFI.

If going to all the effort one might want to work toward that.

Note that the stock internals are limited to about 6700rpm or the rod bolts become questionable.

The K27-7200 turbo will quickly hit its limit on EFI with 964 cams. It would be a better fit with something like a torque build on EFI, stock cams, with larger intake ports. Could work well with the stock 4 spd if diving in traffic a lot.

I am not an expert but I would not see any reason for a wasted spark single plug. Just let the EFI fire the stock system. Better yet add MSD on top of that.

The next step up might be a wanted spark twin plug.
