Is a R32 GTR harmonic balancer the same as 3.0Lt VL commodore or Aussi. skyline

Yes it should be.

The 20, 25, 26 and 30 are all the same but there was one difference in all of them and that was the power steering belt. Some used a 4 rib belt and some a 3. You have to make sure the balancer matches your application but even if the 30 has a 3 rib for the p/steer, you can still use a 3 rib belt on the 4 rib p/steer pulley.

The p/steer is the section on the balancer closest to the front of the car.

BTW when would you need a harmonic balancer?
^ anyone?

i hope these questions arent related.

i cant be 100% but EVERY engine has a harmonic balancer..

cant think of any that dont.

ATI lightweight balancer are for engines that are built for more revs than std.

a harmonic balancer balances the odd vibrations in the crankshaft caused by the explosions in the cylinders. a cranckshaft doesnt rotate perfectly if it wasnt balanced using a balancer it would rotate itself to shreds. the cracnk in a manual car is has to be balanced by a balancer due to clutch engagements and disengagements on the outher side of the crancnk which also causes odd virbrations

also its not a balancer, its a damper. It has nothing to do with the internal balancing of the engine components within. It simply sits on the end and absorbs harmonic vibrations and converts that energy into heat as its absorbs through the rubber rings that are within the hub.

A balancer implies that it is essential to have on the motor as the whole engine would be out of balance internally without it, a damper can be off the motor and it would still retain a 'balanced' state, however the shocks and vibrations would sure as shit kill everything.

I think alot of old style motors have true balancers eg. many v8's from the day.

Also you would most definetely need an aftermarket damper such as the ATI one when your are pushing the factory engine past its reliable redline, making obscene amounts of power or your into the serious drag racing thing.

      Duncan's V37.......race car?

      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.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
