hey guys got a s1 rb25det and i am rebuilding it and i want to do it once and right. ive read a bit and i see that harmonic balancers suprisingly play a big role in motors. so i have looked up ross balancers but i dont think they do rb25s???

what brand do you reccomend and who sells them at good prices. im in bris but i dont think it matters where i get it from as i can just get it posted.

yes i did search but im retarded and probably went right past this exact thread. sorry if that the case haha.

cheers, Steve.

Hey Steve,

What brand... ATI http://www.atiracing.com/

Where to get one...

Aussie Stock, if you want it soon

CJ motors - contact Jackie

If you dont mind the wait..

Summit Racing

Horsepowerparts

You can run a Rb26 balancer on your Rb25 but it will require a few mods. see below..

well there is word that the current ross balancers are better. but I can count a number of people I know personally who had a ross and stopped using it in favour of an ATI. I know 1 case where the guy had a ross, had it replaced with a newer model ross and still had to go to an ATI in the end. yes the ATI cost more, but I guess it's a case of getting what you pay for.

the precision parts ones look good but I have no experience with them. if you are really hard core consider a garage saurus crank pulley. they are solid, no rubber. but supposedly if engine is balanced well they are a good way to go.

what was the reason/s he/they stopped using the ross ones? no point saying they are crap and the ati ones are far superior if there arent any real reasons

i can get a few things from the above...

crank bolt came lose - who didnt do it up/put it on properly?

crankshaft snout out of round/out of tolerance - who didnt check crank/balancer tolerance?

balancers dont just come off by themselves

or is there something else that happened?

you can guess or make asumptions...here are some things that "are" known...the workshop in question has built almost all of australia's highest powered GTR's up until a few years ago...they own a 2 metre long torque wrench to do all their balancers up. This was the 1st time they have used a Ross balancer, they use the correct process to install them, they have never had a problem in the past and have never had an issue since, the crankshaft was a brand new full counterweight item. This was the older style Ross item which was little more than a glorified pulley for the belts. I understand that Ross since then have changed their design.

i was in the same boat choosing a harmonic balancer a few weeks back, some ppl here dont like ross yet www.ripsracing.com use these on all of their street and drag engines including their drag 1300hp donks, that confirmed my decision. fyi, rips build and ship engine packages all over the world.

i think the above mentioned failure was a factory fault...for example, my dad bought a torana ss 5.0ltr and it spun a bottom end bearing after a few yrs. do we draw from this incident that all toranas are unreliable? no smart ass comments :nyaanyaa:

i dont really care who did it, how they did it all im interested in is how it was 'thrown off'. i dont understand pauly, explain it better please

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2

      Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z" It's not a diff. It's a transfer case. Totally different thing. Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.
