If you looking for a 3076R equivalent then go the 0.63/ 5558 which is what I did from research and Unigroup's advice, if you looking for bigger, then consider the 6XXX series...

I spent a heap of time comparing numbers on this also.

For memory when I looked at this (I dont have the numbers on me) the 6262/6266 are pretty much similar to a GT3540 and the Precision 6466 is somewhere between a GT3540 and a TO4Z# .

Obviously how these would drive will also vary based on the rear housing size/ split pulse or not etc.

The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

All the T3/T4 ones are, AFAIK.

If you got one of their garret copy items it would have a water cooled core (IE the T28/GT30 variant stuff).

I always assumed bb chra had oil and water cooling.

I guess no one has had many issues with it though.

What did you guys do with the water lines? Just link the feed to the return with a braided line or something?

Tune all done, ran out of pump (fuel) top end so we stopped there but I'm fairly happy with how it went... May chuck another pump in and see how it goes but I'm happy for now :)

PTE 6262 on stock bottom end RB26 with a Greddy 1.2mm head gasket and Greddy drop in cams

600hp at wheels? Very nice result gotta be extremely happy with that !!

Sucrogen, we don't get E85 on pump over here :(

About 450kw at the hubs yeah, boost is on the graph 1.6bar to beef up the mid range and 1.4 bar top end. It's running E85

Awesome results mate. Hurry up and go to the drags :)

I considered cams :)

Hows it feel on the road?

Maybe, depends if I can be stuffed. Cams should make a bit more power, if you do cams I'll do another pump :)

Only drove it about it 200m, gave it stick in 1st and 2nd, held on... Was good!

What rear housing is on the 6262?

T4 0.84 divided

Very nice power! Looks a bit laggier than a Gt3582r, which isn't really that bad news on a turbo that will make as much power as this if you tried pushing it :-)

We overlayed a few GT3582R graphs and they were similar response. Remember hub dyno makes things look lazier than a roller graph and the run was only started at 3000rpm so not much time to wind up the big girl. Could make big power with another pump though, would go close to 700 if we were crazy haha

The boost isn't falling over top end either, it's just we layed more boost into the mid range to beef up the torque. If we had held that boost through it would have run out of fuel (and probably make another 30-40hp)

Yeah it's pretty clear it has plenty more flow in it - no question of that, for the lag it'll make way more than a GT3582R. I am most familiar with hub dynos, and the .82a/r T3 single scroll GT3582Rs tend to be all on by around 4300-4500rpm so barely any more lag considering the extra power but I'd have guessed it to be noticeable.

Compared with the T88 it's noticeable haha

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      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?”
