I need some help.... I am looking at building an '81 Regal V6 both normally aspirated and turbo charged for Bonneville. I must use an '81 or earlier body to meet class rules.

Are the '81 turbo cars EFi or carbureted?
Do they have engine management computers?

We can run any engine that has the same bell housing and intake manifold bolt pattern as the original regardless of year manufactured. We can also use any internal engine modifications.

I'd appreciate comments on what combination to use. Thanks-

An 87 block/turbo/intake/etc would bolt up (same intake and bellhousing bolt pattern).
