Hey everyone.

I was driving my rb20det r32 when it was raining today with the aircon on and my car started making a hising noise then the engine turned off.

I pulled over and turned the aircon off then started the car and it ran normally. I drove for a while then turned the aircon on and it started making the hising noise again and threatened to turn off.

What could be the problem? Im sure its only related to the air-conditioning because it boosts, sounds and idles normal.

Thanks in advance.

If its doing it only when your AC is on, i would think its AC related.

Check the belt for the compressor isn't frayed or worn. If the compressor is on the way out, it will put unnecessary drag on the motor; the idle valve isn't enough to stop the motor from dieing?

Yeh, the motor still dies. What do i check for in the airflow meter? what could be wrong?

did you convert your ac system to r134a?

the different gas makes the compressor work harder causing it to steal a lot of power from the engine.

When i turn on my ac when driving, i have to neutral + rev it a bit so it doesnt stall as i come to a stop. After doind that once, the revs stay up around the 700rpm. Just the first time i need to give it a bit of help.

anyone know why? would it relate to the ecu learning to keep the rev's up at the next stops etc?

Sweet, nice work.

So is the AC comp seized? hard to rotate?

yes its seized, needs replacing. i found a compressor on the sau for $50, do u think its worth buying it if i dont know wether it works? I thought they were worth above 250??

thanks

      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

      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?
