Should be much cheaper at a wrecker. Not sure if 33's are the same. Would have measure them up or get in the FAST thread in General Discussion and ask someone to look up the part numbers for both R33 and R34. That's how I've confirmed a part being the same before.

S15 diff bolts straight in...did that on an R34 a little while ago

Thanks Dan,

Was flipping back thru past threads and got to pg.42 before seeing your post! Haha

Understand need to use back the R34 half shafts and only concern is the final drive ratio for the S15 being 3.692 as against 4.083 & worried that the pinion and crown on my diff could be worn after 300,000km causing loud 'hummings' even after changing to Cusco semi-syn 80-140 lsd oil.

Hi Dan,

Just check with you - any issues with the S15 diff box in respects of the final drive ratio and the helical lsd components being different with the R34's(viscous lsd) - is there a need to swap ovr the final drive and if there's any effects on the autobox's ecu?

Thanks!

    • 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
