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.

err when i compared my rb26 balancer to my rb20 balancer the 26 balancer was bigger :|

also wats your reason for wanting to change balancer? i believe UAS to a ross tuffbond aftermarket balancer for some price too

Thanks for the replys, My balancer is starting to breakup (rubber part) and i thought a VL balancer may do the job ?

its completly diferent.

pretty obvouse. gtr's dont run a vee belt for the ac. also the puly diameter is diferant.

it will fit but is soooo wrong

I guess as they say, "that has to be that" Thanks all for your replys.

Try a HKS balancer they work fine on my car. (RB 26) with my new internals it goes all the way to 9500rpm. its good value for the cash you pay for it

[T04GTR]

justy gat an ati balancer instead.. same jut doesnt have hks on it lol

[r33_racer]

yeh i heard hks ones are ati ones but with their name on it and they charge more for it.

BTW when would you need a harmonic balancer?

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.

Thanks for the comments guys but WHEN specifically do you need to replace the stock balancer?

Is there any specific cut off power, rpm etc etc rather than arbitrary figures?
