Hi guys,

I have my eye on a front cut from a 2000 stagea and would like some information regarding the difference between the RB25DETs in them and the ones found in R34s.

I have been told that because they are auto, they have less power. Is that just a simple tuning problem cos they're auto?? Or is there more to it??

How hard are they RB25DETs out of the stagea's to transplant into a manual R34?? I know that you need to change the sump and oil pickup, and that the loom is different. Can anyone expand on this?? Is there an easy way to get around these problems??

Thanks in advance,

Brett

Hey Brett,

The RB25det in the R34 Skyline is the NEO version, VVT type. I have a 97 mod staj with the r33 type 25 motor. The reason that they are not as quick is a simple weight issue. The Staj is a bit of a porker carrying 1650kg dry. How much is fcut?? Are you trying to change the R34 into a 4wd?? Big job!

Cheers m8,

Ken

The front cut also has the NEO version of the RB25DET. I am looking to transplant this into my RWD R34 and need to know of any hassles before hand, so that I can deal with them quickly and get my car on the road ASAP.

I know that to transform the cut from AWD to RWD, you need to change the sump and pickup, but other than that I have not been able to source any other information. Any ideas??

Anyone?? :confused:

i have a stagea engine in my r33 gts4 and it is exactly the same as a rb25det, except that the sump you will have to change because of the 4wd drivetrain in the stageas',loom you can get away with the standard one because i think the stagea loom has the fwd linked into it. im actually taking my stagea engine out and selling it if you interested, because im putting a rb25det in so ill swap the sump myself... pm me if your interested

Thanks specialk,

I already have a stagea engine (Neo RB25DET) that is going in on Wednesday. Thanks for the info on the loom, too. I have heard that it shouldn't be a hard swap, but needed to know if there was any major differences i.e incompatible wiring harnesses etc.

What was your reason for swapping from the Stagea RB25DET to another RB25DET??

i work with boostd (the one who's car got written off) and we are throwing his engine into my car. just had more work done to it.

you are converting your car to RWD? or was his a 4wd rb25det as well?

as far as im aware, the 2wd sump will bolt onto the 4wd block, but not the reverse

Yes. Apparently the 2WD sump bolts onto the 4WD engine but not the other way around. I hope so cos I need to transform the stagea cut from 4WD to RWD.

Does anyone know what differences there are in the wiring harnesses for the stagea RB25DET and the R34?? As much info as possible would be great!!

the 2wd uses a different set of "bolt holes" in the block for attaching the sump

the 4wd block has 2 sets(to suit 4 and 2), the 2wd only has the holes it needs (i think)

Correct :D

Seems like a waste of a perfectly good 4WD engine. They are hard enough to come by at the best of times , without ppl converting them to RWD only. I just transplanted one into my R32 GTS4, because it's the only upgrade (short of a 26).

Why not let some poor soul with a R33 GTS4 use it for his upgrade? You can use any RB25DET in a GTS / GTSt.

    • Haha I do that.. thats when it chirps..The bit point for me is almost non-existent. Otherwise I stall it. But yes, in terms of performance, the clutch is solid af.
    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
    • Reading all this... hurts lol. I have an ENR34 5MT and I paid an inflated USA price for the car alone, had to do tons of preventative maintenance past that, and so I'm over $30K USD into the car already and haven't even touched power.  I wanted to +t it. Not even trying to make GTR numbers, I'd be happy with 250hp.  Can I get away with paying much less to make that happen?
    • Damn you’ve done well, definitely snapping necks.
