Ok got a few questions. I plan on making lots and lots of mods to my R32 GTSt over the next few months to a year, but I'm trying to decide what order I should get them in and it's getting confusing. I was gonna get a fuel pump and injectors, but then I'd have to get it retuned afterwards then retuned again after I get a new turbo, then retuned after getting cams blah blah. I was thinking of getting a aftermarket turbo and keeping the boost low until I get inj, pump, and a engine rebuild. I'm chasing the 500hp mark so I know I'm gonna need aftermarket internals. What turbo should I be looking at? Look at what mods I have now and tell me what I should go with first.

The rb20det will not be able to handle 500 hp with the standard bottom end.....

Might have to look into getting the bottom end rebuilt, and may have even require some head work. Its worth getting the motor done before you bolt on your turbo.

500 hp is a lot of power for the rb20 gearbox also, which might lead to replacing it with an r33 box.

A few things to consider other than just turbos, injectors, and fuel pumps.

Make sure you get a full cost from start to finish in worst case scenario so you know how much it will set you back.

Nothing worse than starting something and realising you dont have that extra 500 bucks for the thing you never thought you would need.

500 hp is not cheap.

    • 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 🍻   
    • 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
