Picked up a standard Exedy for $95 from Northern Brake and Clutch.

Stock Exedy will do you
I beat them up abit with my big 15 but on the stock 15's they are plenty good enough

Clutches are rated for torque. The HP is not important while the maximum torque is. Since "built" engine usually have the same or less torque, you can confidentially use a standard clutch.

HD clutches are rated for more torque. And will better stand up to abuse (clutch dumping). It is the clutch cover (pressure plate) that makes the most difference while the clutch disk is usually the same standard vs. HD. Use a HD clutch for drag racing or burnout usage.

Hey sunnyDaze.I'll be running the same set up in a few weeks time,but my engine will be completly stock.how much hp will you be looking at?

Cool. What brand was that?

Get a vanette hd one, I got one for my old a15 and was only $120 or so.

So I've got a mildly worked a15 for street car and need to choose a clutch. I'll be running a 60a gearbox, stock a12 flywheel, and H150 diff.

Do I need and HD clutch or will standard do? For example Exedy OEM replacement is about $100 and HD is $300.

I don't want do stress out the gearbox either.
