Nah, got someone else to do it on a dyno. After watching it once though, I think I could do it myself now on a dyno. Anyway..... I'll tell you something else though..

I went to someone who claimed he could "street tune" the SAFC for $50 (coz a dyno tune was over $100, and i had no job and was a tight arse). I told him I wanted the hesitating at 5500 rpm that was so common to boosted R33's sorted out. This guy did the worst tune, basically did stuff all difference to A/F ratio's, but he wound the timing right back to 10 deg, so I wouldn't feel the hesitation... Needless to say the car ran like SH1T!!! Smooth, but slower than in stock form!

So anyhow, I wound the timing up to 17deg, boosted to 11psi, and took it to get it dyno tuned. Needless to say I was very happy with the results afterwards.

If u aren't experienced or confident enough to tune it yourself (and u r at the risk of wasting ur engine if you lean it out too much), take it to a dyno where u can have a lot more confidence in your tune....

Thought I would show you my FMIC,

I purchased this FMIC second hand for under $1000 and it bolts striaght up to the existing plumbing...

It's not too big but you can tell it does the job. The biggest improvement was the flow (up high like 4500 rpm) compared to the stock I/C. Then you also notice less heat soak on warm days.

Anyways, I am also aiming for as close to 200 rwkw's as I can. The below FMIC will be fine:

      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

      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
