Just don't run one. Convert to pencil coilpacks with the igniter built in. Many Toyota, Audi or later Nissan (VQ, VR) options exist.

Thanks, this is exactly the innovation I was looking for. Is there a "bolt on" pack for this swap or do I need to get into creative wiring?

Whether you need a programmable ECU will depend on whether the coils will be happy running the factory RB20 ECU dwell time. I think for yaris coils, Audi coils, Nissan pencil coils, etc, they're all fine running original dwell. I think the suppliers of these kits might be confusing themselves wrt the dwell question, because back when people used to use LS coils as an upgrade, they were definitely not happy with the factory RB20 dwell time.

But...."programmable ECU" is a triviality on an RB20. Just put a Nistune board in it. I cannot imagine running any Nissan ECU without Nistune in it. Why would you put up with all the factory stupidity, when you can get rid of the R&R, run more boost, make more power, make it cruise leaner and use less fuel, etc?

Thanks I've had a look at a few, there not cheap either. The only thing that's confusing is some sites say they need programmable ecu and others don't for the same product. 

Yeah I'm in Oz, Sydney in fact

Check RB20 stock dwell time but RB26 coils have 2 ms dwell on the stock ECU and the R35 conversions work just fine without a tune at stock-ish power. Going to R35 coils is cheaper in the long run with how insanely expensive the ignitor is. I bought a replacement but most likely if the ignitor ever breaks again I'm going R35 coils.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      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

      Coolant leak?

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
