Engine Builder wanted

I want to test a theory I have in mind and for this I need some engines that meet the criteria:
Man hours: 100
Year: 1993
Displacement: 5L Naturally aspirated or 2.5 L turbo (max boost 1 bar)
Fuel mix: no richer than 13.0/1
Only ONE camshaft per engine (sohc, ohv if V8)
These engines are preferred as racing engines
No need for mufflers Catalysts.
I need as many engine combinations as possible: 5.0 I6, 5.0 V8 5.0 I4, and also the same engin tyoes with turbocharging according to specs.
I want to see which Type is the fastest around the track and I dont want to putmy bad turbocharging skills in the way of the expreiment.
all engines will be fitted in the same car. whne the experiment is done I will publish the results.
