Okay i have the b20b already and i was looking for a ecu, head tranny and axles for it and my friend found a guy that has the b17 full swap everything except for mounts not sure what to do. Stick with my b20b which i was going to run a na setup for some solo here (autocross ) or get the b17 put that in then i can spend the money i get from b20b block to go to turbo or get some more suspension work done on my car.
