The trx300 (1988-2000, 2wd and 4wd) top end will not fit a stock SX/ES bottom end. Stroke is different, wrist pin location is different.

You can use the TRX300 crank and rod and then the full top end. Or just use the TRX300 engine in the SX, just use the SX output shaft. It's actually a very easy swap.
