i went through the same decision...i got a 97 ls and wished i had gotten a b16. Unless you have money to turbo the ls right off hand..you wont be too satisfyed with the ls..but maybe that was just me missing vtec after going from a type r to ls hatch. the b16 isnt as tourqey but its still gonna be quicker and a good highway car.

B16 first choice. Make more power with less boost. Better flowing head, better rod stroke ratio,etc... LS/Vtec is a good choice if done the RIGHT way. Which in turn would probally cost more money than the b16. I would say a b16 with a b18c1(gsr) bottom end. With the b16 head on that block itwould yield the C/R to about 9:8:1 or 9:5:1 something like that. You get a bigger displacement, much better rod to stroke ratio and a better flowing head.

Actually the CR would be about 9.7-9.8ish according to C-Speedracing's websites Compression Ratio calculator with B18C block and B16A head. ALso incorrect is the rod to stroke ratio being better in the B18C motor, the B16A has a rod to stroke ratio of 1.74:1 , B18C is 1.58:1 and the wrost Rod to stroke ratio is the LS/B20C/Z at 1.54 rod to stroke ratio.

I knew it was somewhere in the that range(couldnt remember off hand). I dont think I said the b18c had a better rod to stroke than the b16a.

ya if you want a fast engine...use the ls bottom end build for turbo and use the b16 head and don't use the v-tec...it will run better low end with the torque of the ls and strong top-end with the b16 head...thats just my opinion.
