okay with the sr20det redtop i know it comes with the stock clutch but is that going to be able to hold up with heavy driving or should i replace it with a newer Exedy stage 2?

i'm just trying to get everything straight cause i dont want to buy the new engine and have no money left over for newer needed parts...

 

Just buy a clutch. You dont know the condition of the one on the engine.

 

I would replace it, save yourself alot of trouble down the road. Its not fun replacing a clutch.
