std auto 300zx would be my bet! they also the fastest for the least amount of money spent. Mates z dropped like 1/2 a second over the 1/4 just from hks pod filter, I think it may have made a little more boost with the filter as well? cat back exhaust, filter & 14psi it ran 12.8@104mph @ willowbank which is a damn site faster than any similar modded line or 200.
