I began to turn a 01 WRX into an STi too. Got through the whole lot except

- 207
- 6 Speed / Driveline

Figure I would do this when i popped either of them, in whatever order. ~2 years later neither have died. Service her and look after her too much.

Was an expensive journey, but no regrets as I have hung onto the car for a while and been able to enjoy it all, as oppose to doing it all and then selling it.

Through doing it, been able to keep the car in really good condition too.

(Waits for gearbox to go boom so i can get a six speed) .. I have too much mechanical sympathy.
