Heavy??? Compared to what? Even a 20B weighs only 145kg (A bit more if
it has the factory turbos on it)
Everything else you said is correct.. BTW, a stock internals turbo 20B
can make 500hp. A modified one over 900hp (racing beat bonneville)

On an EFI question, how suseptible are the GM "Hot Film" air mass
sensors are to backfiring?

Cheers,
