Well this may sound like a dum question but i just wanted know if you could us the clutch and flywheel from the 240sx on the sr20det because the trany is still the same.
and are there any parts on the sr20de that you could use on the sr20det.

I really doubt you can use a KA clutch on a SR tranny.You could use the clutch of some other american nissan on the SR tranny,cant remember the name of the car...somethin SE-R...I may be wrong...
