When I ordered my 3600 from Peter ... He told me that my stock hydros in my 96 were exactly the same as the hd hydro kits that he has. From what he told me, the 98.5's and up NEED the hydro kit.I thought the bigger DDs required it? And 3600 is recomended. Is stock good enough?
Double check with Peter to make sure they didn't change in it 98. Im pretty sure they changed when they switched to the 24 valves ... but double check with himSWEET!! :thumbsup
98.5s cutting it pretty close for me though
