are there diffrent model crossovers?

i was wondering if there are any diffrences in the clutches for a sr20de and a sr20det...... it would seem to me that a clutch and flywheel for either one would be interchangeable.... any way any feed back would be cool......

if you're talking about a sentra se-r, 200sx se-r, and nx2000 you can use the stock tranny (including the clutch) with the sr20det motor. In fact, you have to, i believe. I don't think you could use a FWD sr20de clutch on a RWD sr20det for a 240sx. You can use a Maxima clutch on a RWD sr20det, though. Kinda weird.
