if u looking to race, i sure hope it isnt trinidad cause we all know it has no track..so where u wanna race??
anyway , as according to everyone so far the SR20VVL is the better engine for your money. its easier to find,thats true..then u have to find a gearbox as these engines only come automatic/tip-tronic.and you just prob need an Apexi to bring in your vvl....or so i've heard..
the sr16ve gives approx 170HP and the N1 i believes has an additional 30HP with a little more torque.
but still if you building one for racing i would say try getting your hands on a SR20VET these are beast, they come in the X-Trail, once it could go into a b12 and u got the money, its nice..
the 4-throttle pulsar engine also....when coming to nissan engines, i believe boosted does it best..so why not look for a boosted SR or take a VVL and turbo it..
thats jus my opinion on it.
