ATI Balancer RB26 on RB25?

Hey Guys, 

I have been looking at running an ATI Balancer on my New RB30/25 Combo but for the meantime while the engine is being built i want to throw it on my RB25 Neo. Now i have googled the shit out of this and cant seem to come up with a definitive answer and ATI only have the RB26 listed on there website but are all the RB25/26 and 30 Harmonic Balancers interchangeable? m not too fussed if the only difference is Pulley Diameter or offset as that can be corrected pretty easily anyway its mainly if the actual design is different for the harmonics of the different combos?

 

Cheers

Have you emailed ATI?

Yeah but they seem to be extremely painfull to deal with.. there is an ATI balancer on here for $480 in 2011 and now the same person hes relisted it in a new thread for $550 and wont budge lol. Ah well

ATI say " We don’t make an application for the RB25 Eric’s performance parts in California modifies our RB dampers to work on the RB25 though. "

So I guess you could buy one and modify it yourself or buy one from California (or just stick an OEM stocker on it).

I'm having the same issue with finding out what balance is should be using. It's a 25/30 my intuition would be to use a 30 balancer. However, the question in my mind is that will the belts match up with R34GTT belts?

Just built a 25/30, (in an R33 GTST S2) and used the RB30 balancer. We don't have aircon, and the alternator belt & power steering belt lined up perfectly. The RB30 balancer has a V-belt groove for the aircon so wouldn't have worked if we still had a/c on the car.

Would be nice to find a balancer where I can keep everything.

Use the balancer that your car comes with

I was worried the harmonics won't be similar for the 34gtt won't match the RB30. I guess the question I should ask is what are the engine harmonics for an RB30.
Could those settings be transferred to a 34 balancer that has provisions for the pulleys I need?

Don't get carried away with the "harmonic balancer " bit and just think of it as a damper. Its not an ecu.
