B18B- solid engine
B16A- solid engine (with VTEC)
You guys are neglecting one key point.... He's gonna have an extra swap right now, one which he could probably sell to some sap for almost the price he paid for his b16. Granted a B18B turbo might be able to beat a built B16, it'll cost a lot more money than the $1500 he'll have to invest to get that B16 rippin, and he'll have that extra motor to sell...
If you can tho, get a hydro swap, cables suck....
