hey guys i was wondering if any one can solve this...

My cars been misfiring abit and it got to the stage where when i gave it up... it wouldn't rev over 5g it just bounces back and sounded like something was holding it back, and also sounded gross... i changed the spark plugs and coilpacks, and its still doing it.

It also misfires and backfires around 2g when im in a high gear at low revs... then when i was testing it last night showing a mechanic mate of mine it still wouldn't go over 4-5g it just shat itself and wouldn't let me rev high....

Is this my timing from the computer? does it need a tune up or is there something else im not aware of.

cheers

also does anyone know the if the waterpump in the r33 rb25 is the same as the pump from a rb25 in a r32?

I had a similar problem. I thought it was the AFM. I bought a new AFM and it didnt f**king arrive like they said it would yet, so I changed the fuel filter (which was filled with dirt and f**ked up shit) and it seems to be running perfect now.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
