Project Bugeye GDA WRX: Fixing the Clutch with Exedy
Poor Ian, MotoIQ’s FNG’s daily was his trusty Bugeye GDA WRX. The WRX has given many years of faithful service, but since joining the MotoIQ crew, Ian’s commute has gotten much longer and the miles were taking their toll on the car which has over 200K miles.
The poor EJ205 engine is burning oil and requires engine rebuild in a can (so as not to quickly run out of oil), and the car’s suspension is loose and floaty. To make matters worse, on his way to work, the car sprung a huge oil leak and oiled down the super old clutch, and Ian barely limped into the MotoIQ garage.
Well, Ian has bought a base model Honda Civic to drive to work. The difference in gas mileage between that and the WRX almost makes up for his car payments! In the meanwhile, this frees up the WRX so we can work some magic on it.
To date, the WRX hasn’t gotten as much love as its big brother the STI, and we are eager to explore the EJ205 to see what can be gotten out of it. We feel that the smaller engine is going to be happier to rev and possibly more robust. We will also be attacking the legendarily weak WRX 5 speed transmission to see if we can get it to be durable with more power.
When all is done we would like to do a comparison between the Bugeye and our Blobeye GDB STI. First things first though was to get Ian’s car back on the road, and that was going to require a new clutch.
To fill this need we turned to Exedy for their stage 1 organic clutch. Exedy is the OEM supplier of WRX clutches, so we felt that they would have a good handle on the platform.
The Exedy flywheel is machined from a solid one-piece chromoly forging. The forging gives finer grain properties to the metal and orients the metal’s grain flow in the direction that will best improve strength.
