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.

      gauge needle removal

      By GTSBoy · Posted

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      R-chassis INNER tie rod torque spec?

      By GTSBoy · Posted

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task

      Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.

      gauge needle removal

      By JC71 · Posted

      I have done a lot of research before posting here and on gtruk forum. couldn't find anything. I have my gauges all part except the needle itself. the needle has a extremely small hole in the center, but the shaft going to the needle is extremely small and appears to have nothing to index it either. doesn't seem strong enough to simple pry or pull without damaging something. Already tried the old spoon trick on a extra triple meter I have from a gtt, but no luck. the center cap comes off easily but the hole in the meter face plate aren't big enough to get over the needle itself. figured this would be my best place to find someone who might have actually removed theirs. wonder if there is some type of small pin press tool to push the pin in while pulling the needle base off.

      Ok...its taking me long enough to finally do this.  Feck financial security...heart disease will get me soon enough anyway So welcome to the garage..."Clem" Belsil80 has been running a 370Z in Super TT series. So after entering with him in last years Winton 300 i figured I  need my own car. Seems SAU Vic race cars need to be yellow....{tick} Reckon with enough motor i will be able to make up for the lack of talent and stay ahead of the 370Z... but the LS powered S13 and E36s are a ways up the road Aim is to have a car that doesnt stop or turn but has a bit of shed built motor with jam...maybe some cream  First step is getting this ex drift car log booked I am keeping faithful silver car. As the road-club car gets upgrades the race car wil get the sloppy seconds
