Sr20 are the same fwd. Sentra 200sx.g20. I just can't buy something from a seller that spells Infiniti with a Y. And I'm supposed to trust the shit they put together. Personally I wouldn't even waste my time. Naturally aspirated is not meant for this motor. Stimulus = BFH time. Dude this motor and 20 psi on 2871 daily driver is retarded!!!!! Try it out. Got 1 build done for like $750. Piece them all together. You will love it.
