short answer, yes a 02/03 viper box will work in a 01 srx only, direct bolt in(with bypassing the temp sensor) 04 viper box will fit a 02 srx(same fix is needed and not sure what goes on with the grips on this one)
advance is wayyyyyyyyyyy more. You can not run mid 8000 with this box for long periods of time unless you dump fuel in it and then it doesnt make any power.
it does however work great for a cheap drag race box. If your using a viper box with probes at 7in from piston, look for sled to burn down around 1300, with the srx box, the temps will go into the 1500 range(i never burned it down with the srx box)
