So after a long time rolling around in my head over what engine should live its life between the strut towers of my R32 I've been pushed towards a RB25DET. Now just trying to decide between the Neo version or the 'normal' 25.

Only really looking towards 250rwkw of reliable power.

Was in the same dilemma a couple of months ago. Ended up getting a neo because it's newer, more power and less emissions and plus I found one for cheap. Also may depend on how much money you're willing to spend. If you're on a strict budget maybe go the r33 rb25 as NEO's cost a bit more to buy and apparently a bit more to replace or buy parts for. Up to you in the end..

Let us know what you decide

my vote is busted rb25det normal and you rebuild it before it goes into your car

you get a new engine already setup for the power you want and you can be sure its reliable

and it will be in better condition than a 2nd hand NEO and probably come out cheaper

ie busted RB25DET normal + rebuild < 2nd hand working RB25DET NEO

Safe every day use and power figures are a must. Dont want something the the shed more than on the road. Hell the current RB20DET is powering on like an RB should without a single problemin 2 years. And its had its fair share of flogging to boot.

But all the engine swap ideas came from Mercury Motorsport convincing me building a RB20 to the same kind of power levels I would like is even more of a money pit than normal.

Pretty keen on taking the advice of a shop with a 960+hp R34 GTR sitting out the front (NITTO) and a completely gutted R35 wearing a fresh Carbon front bar.

On a side note...who guts an R35, I was nearly in tears and I dont even like them that much.

details please ellaborate :/

well the neo makes more power from factory so u dnt need to modify it as much to make round the 250 mark (more mods = more money and more stress on the engine) the neo engine runs solid lifters, gtr rods, larger ports, bigger turbo, variable valve timing, u can also fit a live board to the ecu so remaping is a breeze u only have to plug the laptop in, not re chip it.

and neo engines arent really that much dearer than 33 rb25s

dnt get me wrong the r33 rb25s are a awesome engine id just prefer the neo

    • Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.
    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.
