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):

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
