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.

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?

      gauge needle removal

      By JC71 · Posted

      I have done a lot of research before posting here and on gtruk forum. couldn't find anything. I have my gauges all part except the needle itself. the needle has a extremely small hole in the center, but the shaft going to the needle is extremely small and appears to have nothing to index it either. doesn't seem strong enough to simple pry or pull without damaging something. Already tried the old spoon trick on a extra triple meter I have from a gtt, but no luck. the center cap comes off easily but the hole in the meter face plate aren't big enough to get over the needle itself. figured this would be my best place to find someone who might have actually removed theirs. wonder if there is some type of small pin press tool to push the pin in while pulling the needle base off.

      Ok...its taking me long enough to finally do this.  Feck financial security...heart disease will get me soon enough anyway So welcome to the garage..."Clem" Belsil80 has been running a 370Z in Super TT series. So after entering with him in last years Winton 300 i figured I  need my own car. Seems SAU Vic race cars need to be yellow....{tick} Reckon with enough motor i will be able to make up for the lack of talent and stay ahead of the 370Z... but the LS powered S13 and E36s are a ways up the road Aim is to have a car that doesnt stop or turn but has a bit of shed built motor with jam...maybe some cream  First step is getting this ex drift car log booked I am keeping faithful silver car. As the road-club car gets upgrades the race car wil get the sloppy seconds

      Assuming that they will come off without damage at all.... i would have thought just pull straight up off the spindle with a something or other than can reach underneath. Have you searched for youtube vids of people doing similar on R34s or any other Nissan from the same vintage? They should be the same technique, in all likelihhood.

      Wheel refurb?

      By GTSBoy · Posted

      Keeping in mind that sandblasting is really aggressive on softer metals like cast alloy, and you can do damage that you might regret. For trash wheels, not a problem. For wheels with value/scarcity issues, etc.... perhaps a less aggressive media is a better choice?
