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.

      Cleaning my wheels 😍

      By soviet_merlin · Posted

      Ah yes, fair enough! I was purely thinking about cleaning the spokes and front of the wheel with the mitt. For the barrel the rag on a stick makes more sense. I've tried cleaning the barrels on mine and gave up in frustration. Between brakes being in the way or spokes being in the way and limited space to constantly move the car front and back it was just too annoying. The barrel being as shiny as the rest of the wheel sounds amazing though. At this point I'm not even sure if they have the same surface finish on mine. But I feel inspired now to find out.

      I have a wheel cleaner pokie thing which is a glorified microfibre rag on a stick, and there is not sufficient clearance between the caliper and the barrel to clean that section. I just roll the car forward 500mm and have another shot at each wheel.

      The "rag on a stick" is a easy way to fit in between the wheel spokes into all of the barrel Albeit I do have 10 spokes on the MX5 which limits the access to actually jam my hand in to clean the barrel, but it was also makes much easier to clean the 5 spokes on the Dunnydoore with it as well, as you don't have to worry the  caliper getting in the way if you have at least about 15mm space between the caliper and barrel This of course depends if you actually have the clearance between the barrel and caliper, and the amount of OCD you have to get the barrels as clean and shiny as the face of the wheel The thing is bendy as well so you can actually shape it to conform to the inner lip of the barrel

      Alarm/immobiliser recomendations for an R33

      By Duncan · Posted

      FWIW, as well as a basic immobiliser/remote unlock (all basic units give you those 2 things), I would also install a 4g tracker in any car I cared about. Just hide it anywhere that won't be found in a rushed look and preferably get something with a built in battery backup so it stays online for a while when the battery is removed or flat While its not a car, when our car trailer was stolen in that den of crime Sydney about a decade ago, the cops were watching from the bloke's neighbour's lawn within about 2 hours until he started swapping the plates and putting up the gumtree ad.   Obviously it is still not undefeatable (eg parking it up for a few days somewhere without sky sight) but it greatly improves your chances of getting it back quickly and with less damage

      Use text replace function to auto-link to referred threads?

      By soviet_merlin · Posted

      Instead of magic keyphrases I wonder if something can be done with auto complete. Similar to how user names are handled already. When you type '@' and follow with letters, it'll search across all usernames. It might work to have the same for forum topics. Some key to trigger it and then text search across all thread names and it'll insert the name and URL when pressing enter.
