Hi guys, it has been along time since i have posted something on this site, main reason i was living in England for 6 months. i STILL visited the site every now and then. Anyway i back living in Australia for good now for good. Anyway i have just found out that one of my good mates has just bought a WRX 2000 MODEL with 50000km on the clock, it is at the moment stock. I have been told that these cars have a very weak driveline. He is thinking of putting a big exhaust on it, i am worried that modify the exhaust that it may cause problems with the driveline (diff). if something is to break in the driveline i don't think he would be able to afford the repairs. Could i please have some input as to other peoples experiences they have had with WRX drivelines. Yes i know it is only a exhaust. I would have tried to talk him into buying a soarer but he had bought the WRX before i got back.
The big problem for most would-be WRX owners now is that a high-performance car is often a riskier second-hand purchase than something a bit more strait-laced.
In standard trim, the weakest link in a WRX is the driveline. The engines need their servicing, and skipping oil changes is probably the worst thing a previous owner could have done. Without fresh, clean oil the WRX engine will form sludge and wear out far more quickly than it should.
The gearbox isn't perfect and the synchromesh on second and third gears can often fail prematurely, leading to crunched shifts.
The real weak point is the clutch, which often acts like a fuse when the driveline is stressed out (as many owners will attest). Too many hard launches will see the clutch give up the ghost, and replacement is the only viable option once the unit has been overheated too often.
Brakes also get a big workout on a WRX, and the rotors and pads can wear quickly, so that should be taken into account when guesstimating running costs.
Don't know if you guys remember the subaru ad were it has AWD and has what it can mean in some situations. They missed one situation which is AWD-A Weak Drivetrain with some fully sik dude at the drags looking at his WRX on the back of a tilt tray .
They did improve the gearbox strength in the later models, namely the first of the bug eyes.
