Need help! R33 gtst chasing power

Hey guys, 

I recently bought a r33 gtst which has some tasteful mods, custom exhaust, poddy, FMIC, alliminium radiator and FMiC

What can i do to reach 200kw atw? But i would need to stay in budget lets say the budget is around 4k or so. I can also get 1000cc injectors and ems stinger ecu but not sure which version for $500. If i get the ecu and tune it could i see 200kw on the stock turbo or will i have issues? 

Thanks for your wisdom o wise ones.

Yes you could get to or close to 200rwkw on a stock turbo. I wouldn't go over 11-12psi as the ceramic turbine wheels tend to snap off. If you're already getting injectors you could highflow the stock turbo for around $900. Will get you to 250-260rwkw. Will also need a better fuel pump, better airflow meter unless the ems runs map sensor, Afm won't be required.

I got 187rwkw @ 11psi on an average tune with FMIC and exhaust. Stock S2 turbo.

For what you're chasing, on a budget:

  • High flow turbo ($1100)
  • Walbro 460 pump, with allowance for relay mod and bits ($250)
  • Z32 AFM ($300)
  • RB20 ECU, Nistune and Dyno ($1300)

This assumes you wouldn't get the EMS or injectors, and the prices I listed are on the high side. This combo is sub-$3k is good for 220-240rwkw and gives you everything you need to shoot for more power with the addition of a good set of injectors, maybe a flex sensor and board.

What injectors are you considering? I had lots of trouble with injectors, make sure you do it right!

Thanks for the reply! 

Yeah i reckon id be happy with 187rwkw.

I think its bosch injectors... not sure. 

Inmaniac just exhuast and fmic? Stock ecu? And also what boost controller? 

So all id need is ecu and tune for 187rwkw?

If there's any doubt, just go buy new. But as I said, you won't need injectors for <200rwkw

I used a Nistune, but in reality you don't need any ECU upgrade for that power level.

I used a GFB G-Force II EBC, but you can use a bleed valve if you really wanted to.

For that power level, your current mods and then upping boost to 11psi should do the trick. For 200+, as above.

Back in my old days I had a piggyback  safc2,gt28 turbo and managed to get 310 rwhp on stock r33 mad sensor. 

With the ems stinger,upgraded fuel pump+ injectors u should be able to achieve minimum 330 rwhp even do on stock turbo.

good luck mate

Just get a manual bleed valve such as a $40 turbotech or a turbosmart and boost it to a safe 10psi, should get around 180rwkw which is still enough to have fun with.

I wouldn't get a tune with the stock turbo, to get 200rwkw you will have to run higher boost which is playing with fire with the ceramic turbine.

This.

Up the boost, FMIC, exhaust etc etc.

I got 256rwhp (190kw) years ago (no ecu, injectors). Plenty to have fun with until you want to upgrade your turbo (and everything else!).

Lol. No.

OP, get a boost gauge and a manual boost controller (bleed valve). Set to 11psi (max) and go have fun. Set and forget until you have the coin to go bigger and better. That's essentially what everyone is saying.

good luck mate 

My R31 made 109rwkW once (RB30E is a sub 100kW engine).
Surely a GTS1 cam, extractors and 20 years of use wouldn't give it that much increased power? I think I still have the dyno sheet haha.

My old manual r31 silhouette made 126 kw at the wheels. Had extractors and 270,000 kms of wheel spin and burnouts for mods. I miss that rusty piece of crap.

      They will be (within normal range) and they won't be causing the misfiring.

      Should you buy cheap Chinese tyres?

      By The Bogan · Posted

      Chinese parts can be good, it's all in the quality assurance, and materials, but, that costs more, but, typically not alot more, it is up to the customer who is getting the parts made, some are happy to pay more for quality good QA and materials because the savings are in the cheap labour costs, so they can sell a quality product at a lower price point, other customers who are getting parts made give no farks and want their products to be as cheap as possible for maximum profit, so minimal QA and average materials  Hence why some Chinese parts are crap, whilst other are good Much like parts and other stuff made in different countries around the world, including "made in Australia", "made in Japan", "made in 'Merica" branded gear

      By admS15 · Posted

      Agree with Bogan bloke above. I like running quality tyres on my street driven cars. Wife's daily as well as my daily have Michelin PS4, good tyre that does everything you'd expect without fuss and reasonably priced for popular sizes that aren't enormous. Skyline had Yokohama on it for many years but have recently fitted zestino tyres. Just did a quick Google and they're actually Chinese made (jap designed apparently). Surprisingly they grip really well, wet and dry and haven't died, YET. Obviously on the higher end of CCP tyres but still China nonetheless.
