Project 6-speed

[Viper]

Nice work.

Enough room to bolt the bugger to the engine?
Or is it all gonna need to be dropped?

[Norbie]

The 6-speed isn't much bigger than the 5-speed at the front so I don't anticipate any problems there. All the bigness is at the back which is why the tunnel was chopped around the shifter hole.

thats a psycho looking clutch

good to see it getting there dude, well done, definitely unique!

Can we have details on the clutch please?
like price, who did it, and what it's designed to hold (ie: 220rwkw in a 1300kg car vs 350+rwkw in a 1500kg car)

I have a feeling I'll be frying my stock clutch fairly quickly

[Norbie]

It's basically a stock MkIV clutch with 50% increased clamp. It was built by Direct Clutch in Brisbane and cost about $600 including new drive plate, reco'd pressure plate and flywheel machining. The guy actually recommended a 5-puck ceramic drive plate but I decided to try the organic plate first and see how it goes; I reckon what I have here should be good for 500hp at the flywheel but we'll see.

Hmmm solid centre organic? You'll smell slippage within the week i think Norbie

[Norbie]

Rz from PF had a similar setup with way more power than I have, and his current setup isn't much different, just a ceramic button solid centre. I reckon it will be fine for the time being but like I said, we shall see.

Another setback tonight, I was going to put the flywheel on when I realised the bolts I have aren't even long enough to poke through the back of the flywheel much less screw into the crank. Looks like I ordered the bolts for the auto.

ya drongo!
Well done with getting the clutch and everything sorted, and for the fantastic paint job on the floorpan

Tar paint in a can FTW.

Hmm must be some clamp pressure? Full face solids are really prone to slip as there's no spring to take up the initial shock load....once an organic starts slipping it gets hot and keeps slipping.

Dunno how RZ's did the job but common wisdom says it shouldn't

Heavy duty organic on the GT8 wouldn't see 2psi before dissolving on the dyno

[Norbie]

It's a solid centre but that's what a stock V160 clutch looks like, they have a dual-mass flywheel which does pretty much the same thing as a sprung centre.

[JustenGT8]

Ah that would do it then. Combined with the huge dia i guess it's enough? I've been for a drive with you remember...can't see that organicy stuff hanging together long

I'm going to agree Norbie.... Unless you have upgraded your digital accelerator to analogue since last time i was in your Supra

0= cruise
1= skids

[Norbie]

Bah! to the lot of you.

The biggest reason I shied away from the button clutch is because I destroyed 4 gearboxes last time I installed one of those. The first gearbox actually lasted quite a long time because it had the organic clutch originally. Now that I have a $3k gearbox I really REALLY don't want to break it, a bit of clutch slip is much better IMO!

Meanwhile the gearbox swap is still at a standstill as I'm waiting for parts, again. Plenty of other stuff to keep me busy though, such as installing an oil cooler, new gauges, adjustable swaybars and of course fixing the intercooler I jammed into a driveway a while back. Stupid low cars!

[Norbie]

I spoke too soon, flywheel bolts have arrived! Gearbox is going in this weekend, dammit surely nothing else can go wrong?
