Get a LS, later add the vtech head. LS has more bottom end torque, therefore adding a vtech head altogether would be even more powerful low and high end. And after all that, You can still add a turbo kit, go all motor or shoot some nitrogen. b20's are also good but lack some high end in the long run. But as long as you have vtech, your good whatever way you choose. But all in all..just **** it and get a b13(91-94 nissan sentra se-R) and swap in a sr20VE(vvl) motor..get some bolt ons and a ecu/good tune. you'll be runnin 13's all motor with around 200hp just like my bro..
