will this work? I want to build a b20vtec, i have a b20a block and a b18b one. Since the b20a block has the crappy crank, can i use the b18b crank into the b20a and use the b20a pistons and rods jsut like a regular b20b or b20z? what will my compression be? thanks

 

As far as I know, the cranks and rods are identical.

 

awesome, so would this work if i took the b18b ls crank, the ls rods, and then the stock b20a pistons? Then assemble it properly with the vtec head and it will be just liek any other b20vtec? am i missing anything? thanks

 

correct

 

awesome. Are b20a rods the same as b20b rods?

 

Yes, as are B20Z. Change rod bolts.

 

I believe the B20a came from the 88-91 Prelude. those blocks are different

well what i head also worked was a B21A5 from a 90-91 prelude crank and it bumps up from a 2.0l to a 2.2l its a little bit of work and its worth it and its supposibly makes some good power and torque..............


(still waiting on some info)

Yeah you right, A3 and A5.
