Probably cheaper to buy the Porka in a couple of years when the price comes down.

You will need 400hp at the wheels which is low-ish boost FI (TT or SC) as a minimum otherwise you are looking at a 25K NA engine which might be a temperamental PoS unless you hook up with a real good tuner ........ will require at least 12.5:1 comp ratio to make the numbers and then you need E85 to be really safe from detonation unless you are religious about quality gas ... at 12.5:1 - a bad tank of gas could kill your engine, again dependoing on the tuner..

Sequential shifter would be good, but the OEM 7AT "might" be OK.

Forget the carbon brakes ......... they are a $10-$12K ask

The GT4 is a race-car - so you can make a NISMO into an equivalent race car but if you want to road it, I;d suggest you think again - to many compromises.
