So the tune didn't quite go to plan. Clutch started slipping as soon as the tuner started doing some power runs so it was called off until I got a new clutch. Being the fool that I am, i decided doing a 6mt clutch swap in the driveway was a good idea despite others saying it was a recipe for disaster.
Jump forward a week and she's all done!
A second set of hands would have been usefull at times but overall it wasn't as much of a struggle as i'd expected.
Not sure if it would have worked out with a normal trolley jack, got talking to one of the guys at work who had a platform jack for motorbikes so gave that a go. Ended up being a damn good choice as it gave a big enough area to get the transmission set up at the right angle to pull straight off the engine.
As expected it was stuck on the dowel pins and no amount of shaking it would get it free, ended up getting a fine chisel and smacking the hell out of it to get a gap started then got the big pry bar in there to get it the rest of the way off.
Went with an Exedy HD 240mm clutch and had the existing single mass flywheel resurfaced.
Took alot longer than I would have liked but happy to have given it a go and come out on top.
Engagement with the new clutch is a heap sharper so it'll take a bit of time getting used to as the old one was super lazy in its old age.
On a side note, fairly sure the alternator bearings are shot so may pull that apart and replace those too.
Booked her in for a tune again on the 5th of August.
