hi everybody, recently running a project for my Rb25det and getting an idea of putting a T70 turbo with stock engine. the follow are the spec that i am planning to go for.

- nismo 550cc injectors

- 600x300x100 front mount

- hi-mount manifold

- 50mm hks style wastegate

just a question here, i am planning to push my car to around 400hp so is the spec capable to handle the turbo with A/R .80 ? what els did i miss out ? kindly seek for help.

Strongly suggest doing at least valve springs if not cams as well as the cylinder head is at its limit at around 285+ kw. Car will suffer from compressor surge and valve float at 7000+RPM. had this problem with two cars now. one running gt30/40, other running to4z. both of these cars are running Turbosmart wastegate 38mm,

sorry for late reply. well after consideration i have changed the plan. currently putting up a old school TD06 which is straight bolt on( the guy who sell to me said that). the guy claim that without changing ECU, Injectors, anf FMIC and apply standard boost will make 240rwkw. any opinion ?thank

the turbo may be good for 240 rwkw but there is no way in hell your going to get 240 rwkw out of stock ecu, injectors and AFM on an RB25... you need to upgrade all these parts at a minimum.. and then maybe run above stock boost.. to something like 1 bar.

TD06 ... if im thinking correct is not internally gated.

So definately not bolt on if thats the case. And depending on which version of TD06, its not going to be response friendly

Anything over 200-220rwkw requires as a general rule:

Fuel Pump

Z32 AFM

Injectors (or a slight pressure bump depending)

PowerFC or other programabble ECU

So i'd purchase them (costing around 2.2k-3k depending).

Then look at something like a GCG hi-flow (2k). So all up around 6k fitted and tuned. Awesome package then :O

      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.
