Chinese turbo problems

Hi all, I bought my first Skyline 6 months ago a s1 R33 sedan manual turbo, no rego.. It was loaded with after market parts, was thinking at the time I should buy a car that has a lot of stuff done already as it would get to expensive buying each mod individually so the list mod goes something like... Microtech ltx 12, spitfire coil packs, top Mount manifold. Turbo smart external wast gate, custom  screamer pipe,  tein coil overs, gtr fmic, alloy radiator, HKS turbo timer, 3in stainless steel straight through blast pipe exhaust system HKS track purpose only middle pipe, then to top it all off.... A eBay Chinese "super T70 TURBO"... Was having issues with it so stupid me replace it with a eBay special super T70 TURBO haha ha so after 6 months of slaving over my engine bay countless hours under my car just trying to get it all up to spec my hard work and dedication devotion to my rb,, it PASSES road worthy certificate. So happy it's Friday night 7pm bout to Start my life as  a Skyline driver . I get out the drive way my 33 was running good I am out for about a hour till I loose  boost.... Shit, got to injoy the feeling for 1 hour after 6 months of hardship after 16 years of envy. . I get 1hour of bliss. Shit eBay turbo.. So guys be wise and stay away from cheap china turbos nothing but dramas.

Oversized restrictor... Maybe, the seals are gone... She got me home fine, just no boost. Next day I cranked her over n just plumes of smoke in my street, thinking about going back to stock. Stock hot side, if I got a complete setup would be a lot more reliable and cheaper, I got a quote today from MTQ $1900 for a gt35r, But I want to be back on the road tomorrow night not 6 months of saving up for a garrett

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • 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  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • 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 🍻
