What Clutch and Flywheel for JDM STi RA Tranny? (EJ20G)

suby25 · 12-02-2006, 12:32 AM

I got my EJ20G with STi RA DCCD tranny and the clutch and flywheel are totally shot so I need to replace them. This leads me to a few questions as I begin my research:

Can I run a stock USDM WRX flywheel? (If so what years?) If not, what flywheel will work. It's a push style transmission - first production STi RA, MY 94/95 will be running stock starter unless I have to switch to a WRX starter.

I'm also looking at clutches. I found a cheap Exedy OEM replacement that comes with everything needed that I was thinking of running - I just want to ensure it will handle the power of the 20G motor. I know a stock WRX clutch will hold ~350 ft-lbs no problelm, so I think it should be sufficient. The motor will be pretty stock with a turboback and upgraded intercooler.

Paging Jaxx and a few other gents.

The same ones as USDM WRX.
I got a Ej20G engine and tranny and i just used a WRX flywheel, WRX pressure plate, and a WRX disk(i actualy got a ACT unit, but its for a usdm WRX).
