Your mate needs guidance.
The guidance involves a T25 and a Subaru motor.
Been discussed previously, but he's only gone and bought a 2ltr aircooled motor with twin 40's. It's retro innit

But I have been investigating hacked about electronic fuel injection for it as per the later Mexican imports had. Will figure something out, I've already berated him about these engines being "slow
and crap on fuel".
Although there may be a cheeky volksrod lurking in his mates unit that will have something fruity in the rear.
