Help with engine combo

[SFR]

I have engine and intake options and need opinions on the best way to go.

Car 1980 wide body coupe.

Engines, I have: 964 & 993 Turbo
Intakes, I have: 964, 1990 993 and varioram
Harness(s) and ECU - have access to both (993 will cost more).

I was planning to use the 993 with v-ram, however, just realized heads/pistons are from a turbo.

The 964; would using either the 1990 or v-ram intake make sense? Considering the changes (heads/valves) the NA 993 engine has…the 964 may not make the same HP? And the ECU and harness is more costly.

Simplest option, use 964 engine and Intake.

I did consider going all in on the 993 turbo, however, that’s not in the budget when you factor all the changes/parts I’d need to make this work.
