which one works the best on a all stock b16a SIR motor? or rather which one should i get? 90 LS? or a 92 GSR?

also which clutch is better i know if i get a 90 LS pressure plate and throw out bearing and match it with a usdm type-r clutch it would work, but if i go aftermarket i should just get one for the 90 LS right?
