hi everyone,

iv'e just removed my engine from the skyline.

i was thinking while the gearbox is out, i might aswell change the flywheel to something lighter.

i haven't physically checked the clutch & pressure plate, but the car drives perfectly.

my question is...

If i change the flywheel only, will i run into any problems?

Is changing the flywheel something u would only do if the clutch needed changing?

any help will be appreciated

vince

Also i started trying to use the search tool, but iv'e spent 2 hours reading through posts with no luck.

Hey mate, I don't think you should really run into any major problems if you change the flywheel and not the clutch. Just so long as there is plenty of meat on the clutch as i'm sure there will be some bedding in process to occur, probably for the first coupla hundred kays while the face of the flywheel is well, bedding in with the clutch.

By the very nature of this process there will be some irregularities that would have built up over time on the old flywheel that were matched on clutch. Moving to a new faced flywheel should do the same thing to a point, essentially wearing down the 'high points'.

Out of curiosity what kind of clutch is it (organi etc?), and how long have you had it in?

It might save a whole lot of stress now to get a new clutch in while the engine's out. While you're at it, if it hasn't been done, change the rear main, spignot bearing etc.

Another option if you are concerned about the clutches life span and you want to go to a lightweight flywheel is a twin or triple plate clutch. Essentially the flywheel is built into these kits (and is lightweight), and it is reflected in the price. The upside is better driveability, more power handling than stock. The downsides are more chattering in neutral and the higher initial outlay. Although when you combine the cost of a new heavy duty clutch kit and a lightweight flywheel, the price difference isn't all that much!

Probably the best person to talk to on here who should really be able to help you out is 3lit3 32. He works at ABS and does some very good deals for SAU people in Brisbane. He's very helpful when it comes to all things driveline.

Hope rant helps.

You should be aware from the current exercise of the time and effort involved in accessing the clutch. That equates to $$$$.

I would suggest that while it's all apart, take the opportunity to replace (upgrade?) the clutch. It might cost a couple 100 now, but it will cost a lot more when you really need to replace the clutch.

If you already have the uprated pressure plate i'd really consider either a re-puk of the friction plate if it's a puk type clutch obviously or a replacement full face plate.

It's easy to do while it's all apart

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
