Hi guys,
I just bought a 1997 stagea RS4 with a low comp motor for a steal, and im picking it up tomorrow.
I want to do a RB30det conversion (as i have done in my R33) but ive been reading around about sumps not lining up etc.
So i have a few questions (and yes i have searched but cant seem to get a definitive answer) -

1. Will a RB30 block line up with the original Stagea 4wd sump?

2. If not, where would i find an adaptor? (i have read they are available for the R33 RB25 motors)

3. Will the oil pickup work, and if not how do i go about making it work?

4. I have the old motor out my R33 sitting around, am i able to bolt up the RB25 RWD sump to a 30 block and remove all the 4wd gear all together?

Any help would be great or if anyone can point me in the right direction as im new to the stagea game

Its all easy mate, just the normal rb30 4wd stuff

You will need a sump adapter. You will need to sort out the oil pickup. The lower gearbox to sump bolts will not line up by the width of the adapter. The head will be 30mm higher, affects to radiator hose, intake and exhaust.

But that's about all. Plenty of clearance for the motor including keeping the factory strut brace.

Oh, and it is an awesome conversion

Pretty straight forward - as above the only fiddly bit is the sump adapter - some drilling and grinding involved - see the RB30 section for suppliers of adapters. Lower gearbox bolts you can fill, redrill and tap or like me just leave them out.

Here's an adapter kit (or you can get one from Rips or there are other Aussie suppliers):

      Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)

      +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.

      Yeah, my offer was more to show exactly how rough and ready the rig can be and still be useful. Youtube vids will definitely show cleaner setups. Same concept though.

      I would guess the seal has gone down at the speedo drive and gearbox oil has crept up the drive cable sheath and fouled the speedo head.

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Any updates on this? Although not a stroker, nor built especially loose, my car has the exact same symptoms. Although I feel they were not there to begin with. Since rebuild with forged parts I have done about 40k kms and it feels like during the last 15k or so, the oil consumption has gotten progressively worse.  Compression test showed - what I thought at least - similar 10-10.5bars in each hole without oil. I have not yet done blowby test though, due to limited garage access. #2 plug is the looks the most foul and that was the one with 10bars. Nothing in the breather tank. I only recently disabled PCV and left only the hoses running from the valve cover via smallish tank to turbo intake pipe there and did some mildish 2nd gear pulls so the car was definitely on boost (1.4bar or so). Removed a hose from the tank and it was basically dry - meaning, the wipe I used had basically no oil on it. Last time I checked, the turbo and IC piping seemed dry as well (will have to see about that again after those pulls). For the past year and a half though, the car has been driven like a granny would for 99.99% of the time, since it mainly serves the purpose of carrying the family around nowadays. A lot of slow, stop and go city driving and most of the trips it barely sees any boost, but gets up to temp properly every time. Although there can be weeks it is not started at all. The car does not smoke, or at least not that I can see. (CAT is in place though). There is slight visible sweating at the Ex cam cover seal and I recently tightened the oil cooler lines as there was some mist on them too. It runs and idles extremely nicely and feels all around healthy. Like TurboTapin, I too am suspicious of my turbo. I have had IC pipes pop out from 1.6-2bars of boost a half a dozen times during the years. The turbo is a HX35/40 hybrid. So, a very similar mystery. Around 1500kms and a litre of oil surely cannot disappear to thin air. Apologies for the wall of text, not sure if any of the above is useful for best guesses/things to check next.
