Hey R33 peoples or skyline know alls!!!

I have an R33 with what I think is a fuel prob. Everything points to it, but I can only describe it like it's a problem with the airflow meter. (I've changed the airflow)

The Problem:

At Idle: The car may or may not idle roughly; it's not consistent to anything at any time.

Driving: Again it's not consistent sometimes it's a dream to drive, other time it's a mini with some balls. It serges but it I take my foot off the accelerator pedal then put it back on it’s ok.

What I’ve done: Bought a new airflow, serviced it, and changed the fuel filter. Each time of doing one of these COMPLETELY different things, the problem goes away all for 20 mins then mucks up again.

Any suggestions? Please call me on 0433 145 179 I’m going insane! Or just email. But I may not get time to come back on here hence the please call if possible!!!

Thanks

Jen

    • This is what the look like normally. Except we only got the 2 doors locally
    • Back pressure is not really a function of the exhaust itself, but the turbine/housing. So the question/point remains valid. I would be fitting an EMAP tapping point and seeing what is going on in the exhaust manifold before committing to throwing boost at it. Flow. No intercooler is actually rated for continuous operation at any power level wrt temperatures, as they are no actually capable of shifting the required amounts of heat on a continuous basis. They get hot during a pul, then dump some of that heat into the external air (and some back into the internal air) during off load moments/periods). You probaby do need a bigger core, given the power level you're already at is somewhat above the "rating" of the cooler. Put pressure tapping points either side of the core (which possibly you already have, if you have a boost source near the compressor outlet and tapping near the throttle for existing purposes) and report on delta P across the core.   I haven't done the mass flow calculation to see where you would be sitting on the compressor map at the ~450is rwkW level we're talking here, but if you look just at the PR you're running at, which is ~2.8-2.9, then you have a really really wide swath of the compressor map to run in, and so long as you were making between about 45-75 lb/min of flow, you should have really good comp efficiency, with the ideal being betweem 55 and 65. I can't see the need to shift drastically on the map to get better results.
    • Welcome 🙂 The ER34 wheels and slight lowering suit the R33 sedan really well. I'm firmly in the 'keep it stock, at least on the outside' camp.
    • Do this, and we'll have a resource right here.
    • "Hybrid" is a meaningless term. I could not tell you what the vendor of that turbo means by "hybrid".
