Hi guys,

I've currently got a 1995 R33 Gts-4, I'm upgrading to an RB25det...I have found a cheap Rb25det from a GTST which is obviously RWD.

Just wondering how much work would be needed to switch that RWD engine to AWD, I can use the sump off my current block just dont know if it would fit up and what else may be needed for conversion.

Any info would be greatly appreciated.

Thanks guys

Dan

No, the sump bolt patterns are different, you would need an adaptor plate (same as what they use for RB30 4WD conversions) - $1000 +

You really need to find a Stagea Rb25DET and that would drop straight in, with just a diff gear swap (if they are different)

If I was going for high compression I would have just done the de+t conversion....but my engines got 230000kms on it, so I'd rather find a newer stagea engine with around 80-100000kms if possible also installing 32gtr gearbox for different gear ratios as well

If it was possible to find a relatively cheap gtr engine i'd do that as the rest of my driveline and brake setup has been changed to gtr gear already.

I have just done the opposite to you, converted a 4wd rb25det to rwd for a c34 laurel. Strangely the rwd block only has holes for a rwd sump, but the 4wd block has bolt holes for both the rwd and 4wd sump, though to fit the rwd sump I had to modify the oil pickup. if you want to use a rwd you need this.........

In all honesty you are better to find a factory 4wd rb25det engine, usually they are cheaper as its a bit of a pain to mod them to rwd. I managed to get a neo 4wd rb25det for just over $1000 for my 4wd cefiro.

PS, the GTR box has the same ratio as all the other boxes, its just the diff thats a different ratio.

    • 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
