Been a while since my last update, and the reason is that I’ve mainly been waiting for parts…
About a month or so back, I was out driving and noticed that when pulling in 4th and 5th gear, the engine revs increased, but the speed did not. I was hoping that I could get away with the engine upgrades without changing the clutch, but it seems it wasn’t so. I decided to upgrade the clutch instead of just getting a new standard piece. After some research, I opted for the 240mm FX100 clutch designed by ClutchMasters as well as a new 240mm lightweight single mass flywheel to match. Upgrading to a larger sized flywheel holds a lot more torque than the original 224mm dual-mass one in addition to the added gripping power og the new clutch. Installation went flawlessly without major hassles, but I’ll tell you, lifting the gearbox in place when alone is not a straight forward job… I laid on my side under the car while guiding the gearbox with my hands and operating the jack with my feets 🙂
While the car was already on the jack stands and the driveline was disconnected, I decided to get new front suspension control arms and upgrade to polyurethane bushing as the original bushings were worn out. I got a complete set of front control arms and a complete set of bushings for street use (although I got an upgraded (track) piece for the lower-front control arm on both sides). The tricky part installing these were to get the original rubber bushings out of the control arms. I don’t have a hydraulic press which ment getting the hammer and angle grinder out. After some struggling, the original bushings came out without damaging the control arms and the polyurethane bushings were installed using the supplied grease. I also had to replace the rear passenger side control arm as it had some damage and was somewhat bent… I also painted the inside of the wheel wells with an anti-rust/corrosion solution and washed all the parts that had to come off.
I also upgraded the exhaust downpipe as I only had done the first 30cm or so when upgrading the turbo. I decided to go for a 3in pipe all the way back to the 2.5in Simens sports exhaust. In addition to this, I fitted a flex-joint so the exhaust can move without damaging the turbo as well as a v-band joint for easy removal in the future. I also fitted a third lambda-connector in case I want to install a wide-band air-fuel gauge in the future.
