Do Late Series Ii R33's Have Neo?

[HotPlates]

I've heard that the late batch of R33 series II ('97 onwards) have NEO RB25's. Is this true or myth? No speculations please.

[tm_r33]

pretty sure they are only in 34s mate... hope i dont get proved wrong here lol

[Lil_Bobby_260]

Went in stageas as of 1996 in DE form (non turbo) then in turbo form for the Series 2. Didnt come into Skylines til R34.

Cheers.

yip my mate has the latest of the 33's...a 98 model and its not neo...has the r34 crank angle sensor and thats about it

[Dragonforce]

Neo's only in r34's.

[sloutch]

like what dragonforce said. All the R33s have the normal RB25DET. Only R34s have NEOs.

What's a Neo?

^_^

Mines a March 1998 R33 and definitely aint a NEO...

correct me if im wrong but as far as i know 'neo' is nissans answer to V-TEC

Have to hook up a light in the 34 that says neo every time i hit it like the hondas. NEO-YO !

[Sklyn]

Yeah, mines '98 40th anniverssary model and not NEO.

That's the first time i've heard that. Don't think it's correct.

nope. basically the same engine but run a bit more efficiently. still an rb25det. the variable timeing engines are VE eg SR20VE (variable cams as opposed ot double cams)

The RB25DET original has VVT but its only like On/Off whereas the NEO has fully variable VVT. Its been covered on here before.

Also, the NEO has 60N-m more max torque and more than 1000rpm earlier in the rev range, so basically a lot more torque at lower revs...

Its also got an extra 20kw peak power, and to top it off, its a touch more economical as well. So yes, I'd say its improved to run noticeably more efficiently. Not a huge difference (appart from torque) but a noticeable difference.

Most of these improvements are all related to the improved VVT, which may be why someone mentioned it being nissan's answer to V-TEC. But I think nissan's answer to V-TEC could just be the TURBO lol! Give me boost and bucketloads of torque anyday over those tiny V-TEC engines that need a car that weighs less than a jellybean to make them go. Sure they're quick, and the technology is great, but they just lack torque.

(maybe I'd think differently if I had a lighter car, but having performance AND practicallity in the one car is very very nice)

I've also been told the NEO has direct injection, but maybe someone on here could confirm that?

It can get confusing referring to both engines because the engine code is the same for both.

The NEO name is probably just given to differentiate between the two. Nothing to do with V-TEC at all in the name.

NEO is the greek word for NEW. god only knows why the japanese are using it though.

[typevu]

NEO is the abbreviation word for "Nissan Ecology Oriented (engine technology)"... god knows what the greeks are doing with it!

I should have asked whether the RB25DET has VVT, as I thought all that NEO is is just VVT (like VTEC) anyway.

Take the R33 up to 5,500rpm and there is a nice kick. I assume this is the VVT coming in. Is that right?

[typevu]

Its called "VCT" in the RB25DET... not as good nor anything like VVT/VTEC though.
