Rb25det And Rb25 (neo)

[SKY 34]

what's the difference between these two, I read some other forum says that the Neo has mild V-tech (Nisan version). Is this true?

I'm considering fitting Greddy intake plenum, but they only produce for r33. anyone have any idea if they will fit in R34?

thanks

The RB25DET Neo has variable valve timing and lift. The R33 RB25DET also had variable cam timing but to a lesser extent.

There is only about a 20kw power difference and not much torque. I do not believe the R33 plenums suit the Neo (someone has asked this in the past) but I can't remember the reason.

I also have a question about these motors as I am considering a neo for my r33. If I put one in would I need the r34 computer as well considering that I have a Microtech LT12 installed ATM?

The best idea would be to contact CYA34 if you can because he mentioned he had a Microtech on his car at Massive Skylines Cruise 3

I think so once you replace r34 engine, wouldn't everything need to be neo?

pfc has a different unit for each of the r32,33,34 GTT GTR....so I think have to get a diff ecu...ask CYA34 I guess
