ok if you guys really knew nissan engines this wouldn't have started. first of all the guy that said nissan and power don't go in the same sentence if full of sh*!....there is an engine out there..the SR20VET...it produces 276 hp..from a 2.0 four banger....that is faster than any S2000...or you could take the SR20DET which has 250hp....also faster than the s2000...the silvia S15 runs a 13.6 QM stock...the S2000 runs a 14.0. 4 bangers can have power...if i could get one of these engines in my X i would...oh and the skyline isn't a V6 it is a twin turbo in line 6
