Dont get a SR20DET!!! you should get an SR20VE. cost the same as a DE, but the SR20VE has NEOVVL which is VTEC but from nissan.and also, the SR20VE is the most rev-happy out of pretty much any other nissan engine ever made. with some simple mods like porting/polishing, performance valvetrain, valve job, you can rev up to 9 or maybe even 10,000RPM's!!!!
just look at this 11,000RPM SR20VE:
