hey guys,

its a motor i actually havent researched into at all... im just curious if anyone has any pics of it with the plastic covering off and also has anyone tried to run over 250rwkw through one with standard internals without hassles?

hard to work on or same as r33 rb25?

thanks in advance guys, :(

This Neo-6 came out of an R34 GT-T. It's had an RB26 inlet manifold conversion. AFAIK the ones with the Neo-6 cover don't have any 'Twin Cam 24 Valve' badging on the black middle peice... just a plain plastic spark plug cover.

Rezz youre a legend! thanks for that... i was scared they looked nothing like the r33 rb25 under all that covering haha...

now the question is - do they handle mass amounts of power and limiter bashing on standard bottom end (head will be modified)?

also interchangeability inregards to parts from the r33 rb25det... ie will r33 rb25det cams and camshafts work, injectors etc

Ok, 'Power Garage TestaRossa' (my preferred RB tuning garage :)) say that the RB25DET Neo-6 is a huge improvement over the R33 RB25... also the Neo-6 (later ones) are rated at 280ps from the factory, so I think they'd handle as much as the R33 RB25 and then some! I've heard that up to 70% of the Neo-6 RB25 is all new. I think most of the differences of the 2 engines come from head and cams... that means: R33 cams can't go in the Neo 6 RB25, theres some differences with the cam angle sensor or something... injectors I'm not sure, but that would be easy to find out yourself.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).

      @Murray_Calavera nah, not available yet, they're gearing up for it but won't be available for a few years. So you reckon fuel is the main issue? When this bottom did over 600rwhp it was running big single, twin Z32 MAFs and believe it or not, e manage blue, an old school piggyback 😅 not really a fair comparison but I guess it shows how a big single differs to smallish twins.

      @Darrel Can you get pump e85 where you are? If you want to max out those turbos, e85 + bigger modern injectors will be the easiest way to get you there.
