Listen up I need help I am looking for a B18 motor and was thinking of buying 1 from the dealer but the $$$ is the problem with buying it from the dealer. One of my racing buddies is trying to sell me a B18 head w/ a B20 base and a SI tranny. Which way should I go I know that the B18 is better to work with but the offer is tempting. I would love to put that in a 1989 Hatchback.
