I'm currently lookin a several R33 GTS25-T's that are for sale. If I were to buy on I would definitelly consider changing several things to make it go faster and handle better.

Everybody reading this in Australia knows that a HSV Scubsport is a reasonably fast car (297Kw @ 6000rpm and 530Nm @ 4400rpm). My aim if I was to do buy a R33 GTS25-T is to make the CUBSPORT look likes its standing still when the peddles to the metal!!! so to speak.

I was thinking of:

  • changing the turbo
  • replacing the intercooler with an r33 gtr one.
  • high flow 3" exaust
  • changing air filter
  • changing sparkplugs somethin platnium for durability and lowering them to about 0.8mm
  • a new clutch

Please give me as much info as possible. I have a reasonbaly strict buget ($5000 - $10000).

THNXXXX :)

all car manufacturer figures are at flywheel. that hsv probably makes around 240kw at the rear wheels. a mildy modified gtst should be able to take it down quite easily. budget around 6k in mods and that should do it.

stock gtst manual

+ full exhaust

+ boost controller

+ ecu

+ cold air intake

+ tyres

+ suspension

+ clutch

+ fuel pump

+ intercooler

+ tune

should cost somewhere near 6k ish and get your around 200rwkw

    • 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
