or go turbo, which will net you the ultimate torque gain on such small displacement engines. Nitrous will add a substantial amount of torque, but turbocharging adds the most.Originally Posted by BTLFED
either way you will want to built the engine to handle the extra power from the nitrous or turbo.
I suggest starting with a B18B bottom end. They are cheap and parts are readily available. upping displacement is the easiest way to gain torque. Just make sure if you get a B18B bottom end, you upgrade the oil pump or at least the oil pump gear to compensate for the higher rpm. Upgrading the bearings wouldn't be a bad idea while you're at it.
if you want to stay N/A, then get a set of pistons and rods for the B18B block. A good set will only set you back about $600 or so (eagle esp rods and your choice of pistons). Compression ratio of about 11:1 should be enough if you plan on keeping it a DD. Always use good bearings when rebuilding the bottom end. Make sure to get a good LS/Vtec conversion kit. Have your B16A head ported and polished, get a set of cams, valve springs, and retainers, a skunk2 IM, larger throttle body (or have yours bored) and some larger injectors. Make sure to get a good fuel management system, such as hondata. With a good cam setup and a good ecu tune, you should be able to get 185-200whp from a LS/VTEC and still keep it very reliable and streetable.
