First up... yes ive searched. the search function on this forum is somewhat dated and needs an overhaul IMO... due to bringing up so many irrelevant results up which have nothing to do with the search query

anyway, bitch aside, im putting together a neo powered drift car, some of you may remember i used to have a R32 with stock RB25 with 3071R making 280 rwkw on 17 psi with cams and gears. I still have the 32 these days but its pretty stock these days and the 25 is still in it but stock turbo etc.

i understand that 300 rwkw seems to be regarded as the limits for an internally stock 25... and mine with 28 never posed ANY probs whats so ever and was reliable as hell... soooo Whats a neo motor like with similar power levels?

this time round ive got a 3037 with high mount mani, hks gate and cams + injectors, will be running a nisstune again (love em) and am hoping to make similar power levels.

Is the CR the same in a neo compared to a 33 25?

cheers for the replies... if any.

i know they have solid lifters, but from the searching i did, everyone seems to say they think they have GTR rods... but no confirmation.

Pretty sure there was a thread where someone pulled some out?

i remember reading an article in a magazine about a r34 putting out a decent power figure (goes through pile of mags next to me) ok it a performance imports mag from some months ago, got a red 34 gtt in it, makes 364rwkw on an internally standard 25 neo, and they reckon it was pretty reliable too lol although i wouldnt expect that to last too long without going bang, but then it does prove the fact its possible

i dont think 364 rwkw stock motor would last with me driving it :D

yeah so long i can do what i did with my old 25 i'll be happy. 280 all day every day.

is the C/R ratio same or different to r33 version?

We did up one and only could push .9 Bar on the stock Turbo's.

Strange, because I always thought that 1 bar was safe for RB25's and Neos......Not.

Even with a FMIC, fuel pump, exhaust and computer upgrade it pushed 180RWKW's.

This is an Auto and not manual driven around the city daily.

The Neo Motor is not the best stock motor to draw reliable power from.

If you push it to its limits more than likely you will need a re-build.

300 RWKW's day in day out with stock internals?.....

Depends once again on the Dyno your using.

180rwkw for an auto is REAL good, i would not be complaining :P Manuals top out around 200-210rwkw.

as for 300rwkw reliable out of a RB25 i could post about 6 cars that see regular drifting days (about 6 -8 events a year) and if they can endure drifting they can endure anything. These cars have also ran @ other dyno days. DA driver Chris de jager is one of them and if you think a TD06SH-25G on a rb25 making 300rwkw is unrealistic i dont know what else to say... :D ps his motor has done three seasons in the GFB car before we tuned the TD06SH-25G in his new S15....

    • Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...
    • 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.
