[SalEsh]

if such a thing exist, it would probably be

R32 GTS25 = RB25 Type I
R33 GTS25 = RB25 Type II

that's the only thing I could see...

[Murphy]

Well the Neo has some differences to the others, maybe that's what's referred to? check www.meggala.com

[spikeone]

right.. can't forget the Neo motor...

[klys]

didn't the neo have variable valve timing?

[canadianskyline]

Yes, thats what the difference is...also the neo has top feed injectors rather than the regular rb25's sidefeed. It also came with a gay motor cover....

[funkymonkey]

RB25DE and RB25DET all come in a few variants...
first variant without variable valve timing, same PTU as R32
second variant without variable valve timing, smaller PTU and ignition timing controlled by ECU
third variant with variable cam timing (often referred to as the series 2 as it was a major variant in power and technology)
fourth being the NEO engine

with each one a different ECU was also used.

An SR20VE has VVL which is Variable Valve Lift and Timing. The "series 2" RB25's and the Neo series RB20's and RB25's all came with VCT, which is Variable Cam Timing.

What's PTU mean and what are these NEO RBs?

[Daryl @ RightDrive]
