Just wanted to know if anyone knows anything about swapping motors, like the B16A2 head on the B20B block. Just recently blew the block on my SiR motor, just a big *** crack on the block. Checked the head and just 2 valves were bent. My question is.....is the swap hard to do yourself or better to take it to a shop??

Golden eagle makes an LS/vtec kit. it gives you all you need to mate the head to the block all you need is some GSR head studs go to ARP for that. it would be easier to use a b18a/b block since they're cheaper and easier to source out. you also have more options should you decide to change pistons to raise the compression ratio. if i were you i'd pick up a b18a/b short block, put your b16 pistons on the b18 rods/crank, take the oil squirters from your block and have a machine shop install them. get the GE ls/vtec kit put the head on with new valves tune the ECU and call it a day. easy 160whp and enough torque to put many swapped cars to shame.

do you know any good machine shops that would resurface the block and head and do a port and polish??

u cracked the head? do u mind me askin how u blew this motor... b20vtec is good becaues you get good tq for cheap... if u can afford to get the block sleeved then ls is better because you can machine it out to a 2.0 and then get it sleeved if you are like most of us that is out of the question... b20 is a good cheap all motor setup...

if you build an LS/vtec properly, you won't need nos. the b20 sleeve is thinner than an LS by 3mm, thus making it weaker.
