My friend and I are working on motor ideas for his teg. We have a B21A1 block from a 91 prelude si and 2 different heads left over from other builds. We have a b16 head from an SIRII and an Ls head. Which one would be the better choice for that block if we were going to run a turbo

NEITHER
the b21A1 is NOT THE SAME B20 that most people do B20Vtec conversions with. Its totall different. that block is trash, throw it away.

most B20s are from the CRV line of cars. not the older preludes which use a different crank, sleeves, and rod. They are garbage

It can be done with the b20a/b21a......BUT ITS NOT WORTH IT...too much work for not enough power.
