okay, i have a old school prelude motor b20a, could i bolt a b16 head to it?

 

no
not the same at all as the other b20s we have today
no vtec for you
slap a turbo on it

 

no. Even though it's a B20, it's not compatible with later B series parts at all.

I've not heard of one being swapped into a Civic either, although someone in the classic forum is throwing one into a really old Accord.

Let us know if you get it in. I'd be interested to see it.
