ive seen standard autos take 250kw with no problems.

ive also seen built ones take 300kw+ with a shift kit and a clutch rebuild.

someone on here has run 315odd kw on the auto, look up either 4doorsleeper or dangerman4.

both have high powered auto's and lots of info in their threads.

Yeah Keas in Melbourne is the right place but I would recommend you get a valve body upgrade from MV Automatics in Adelaide then get any old auto transmission place to put it in for you. Mike is head and shoulders above anyone else in Aus when it comes to Jatco trans.

Also I strongly recommend you get a trans fluid temp gauge in your car. It's well worth knowing what temp it's running at and would have saved me a full rebuild if I had one before I killed mine.

Yeah it's dangerman4, his last dyno run was ~300rwkw which, also is believed to be the limit of the stock trans w/ upgraded valve body. Also, a complete rebuilt one from MV Automatics has seen around 500rwhp.

so what have u done exactly to your auto tranny to get it to take 300kw?

With Just the MV Valve body it can hold up to 270rwkw, its a really good idea to get a Trans Cooler also to keep it from heating up too much. But shifts really nice well worth the money.

yeah i have a pwr trans cooler already put on. i like the sound of the mv shift kits but id rather get someone here in melbourne to do it in the shop. so the mv valve body is basically a stage 2 shift kit? is a mild or heavy when the gears change?

      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.
