Recommended Posts

Hi everybody in Aus.

Now I search some data for dicision about my new engine.

(My old is 240,000Km)

my old engine is RB20DE AT with 4.083 (Don't know its called in english..)

I interested about NEO Engine but don't know about its spec.

I would like to know about this engine detail.

One thing I heard that NEO6 is save ur petrol right?

You know in Thailand petrol is expensive (If u compare with our living costs ):) & my city Bangkok was very traffic jam

or If I find some new engine for save petrol it's will be NA engine RB25DE NEO or not NEO :)

Anyway wait for suggestion........:)

If you are worried about spending too much on petrol, why are you ready to spend all that extra on an engine????

Sorry, just doesnt add up.

An RB25DE shoud fit no probs and with the money you save from the conversion (vs RB25 NEO) you will be able to afford the petrol.

So is the RB25NEO more economical than an RB20DE? and by how much. Really if you want economical, buy another RB20DE, they are as cheap as chips. Even an RB25DE can be picked up for around 1K in aust, but as the NEO engine is a bit rarer, I wouldnt have a clue what they are worth, but I am sure they are more expensive again.

Have a look at some of the back issues of HPI - did a build up on a R43 GT-T, and they used a high flow for approx 230kw(from memory) at the rears.

I believe the NEO has a larger range of VVT than the R33, also the cooler on a GT-T is different to the GTS-t (presumably alot better) It would be quite conceivable that with a better tune, better cooler would easily make an extra 20kw.

BUT I think tumso is looking at the DE?

Tumso, you will also have to get an ECU upgrade if you change engines.

the best thing to put in your cefiro is an rb 25 from an r33 rather than the neo as the that rb25 is similar to the rb 20 the neo is very differnt. yes I have seen cefiro's with rb 26 :D they go very good. another thing to think of is an sr 20 I put one in my r32 skyline came up well .

Yesterday I went to see a skyline r34 engine rb25det neo for conversion my car.

Unfortunatly! air flow was broken.

I saw neo engine air flow was Pink label

same RB 25det (r33) but not sure it's really same.

If it same I will purchase a engine cause I think I can find a spare part

if not I must find another engine

Pls Tell me

    • I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?
    • Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?
    • So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good
    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
