First thing to do:

timing belt, water pump

Reason why?

Most imports have had their clock wound back, or clusters have been replaced

Then:

  1. Full exhaust (just get 2nd hand) ~$500
  2. Intercooler of some sort, even a R34 GT-t side mount $100
  3. Hit up Toshi for a socketed stock ECU with a new ROM tuned for AU 98 Octane fuel ~$350
  4. Turbotech MBC 0.8bar ~$30
  5. Fry tyres ~Priceless

The only thing I would add to that is a new fuel pump. The second worst thing that can happen to a 20 year old car after a shredded timing belt, is a failng fuel pump.

Johnny's list is solid.

If you want to go further than that you will find out that everything on the R33 has been sized just right for factory output plus a little more. Figure out what your ultimate power goal is and work back from there to see what needs to be done.

This times 1000!!! I spent about 20 grand on mine when I bought it. Thinking back now could of saved a lot of time and MONEY by researching more. I would of saved about 8 grand and over a year of time for a better result.

Ha ha. I also would have saved a bucket load. 3 turbo's before i reached my power goal,

Part of doing timing belt and waterpump is replacing cam seals. They will leak, they cost less than 10 bicks each and you have to take timing belt off to do them, so do then at same time.

Who's Toshi? lol

P.S Thanks for the help fellas!

Just a thought, see if you can pick up an rb20det turbo actuator and swap it with the rb25 turbo actuator. I've seen the individual actuators sell for around $50. The rb25 turbo actuator is set on roughly 7 psi whereas the rb20 turbo actuator is set on 10 psi.

Just a thought anyway.

Agreed, mine leaked at about 160k and they were rock hard. Chalk that up as number 6 on the list of things the dropkick knuckledraggers I took it to for the 100k service didn't do properly.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
