My engine is still going strong! 11000kms on over 350kw now :D

man those R34 NEO motors are built like german nazi tanks lol

it seems like it's more economical to drop in a R34 NEO motor if a R33 RB25DET motor ever carks it

They tend to hold together pretty well! Ill admit mine has had a hard life too! Its been overheated (Well got warm but Haltech shut it down) and also had a LOT of fuel dramas which caused all sorts of bad AFRs early days... I try to keep it off the limiter but it still gets spun to just over 8000rpm when up it haha

Sick effort. Mines close to getting on the rollers. Patience is running thin though

It gets like that! Itll all be worth it on that first drive though ;)

Funny thing is I'm the one doing all the work. Just a matter of putting in the effort after working all day on shitbox cars (skoda). Sometimes all you wana do is sit on the couch and not move lol. Will be tuned within the month though

I would like to be able to say the same. But i give mine a fairly hard time. Seen 2 track days and lots of limiter, although mine is set at 7450 from memory not 8000 haha.

Even driving it very hard, no blowby AT ALL! or any oil/fluid leaks, just running the standard nissan setup. ie linked rocker covers and then a hose to the intake after the AFM.

The thing i am most impressed with is its off boost driveability though, it is insane! Put your foot down in any gear and it just accelerates, even crusing at 100 in 5th, half throttle and it just accelerates to 120 easily all while off boost!

I am certainly very impressed with the NEO!

Unfortunately mines dropped cylinder 5 :( flaming mongrel!! Im not sure what caused it, had plenty of vacuum leak drama from the plenum in past year and an accidental overboost of 25psi in third, all cylinders 155-160 and number 5 is 60..goes upto 200 with some oil squirted in.

rebore and forgies n rings or drop a stocky? thoughts?

I thoughtyou sold your 33? You building another or same but different way? Id throw pistons and rods at it but all depends on your power goal and what you wish to do with it.

that was the plan, but then discovered the dropped cylinder and now thinking ill just have another crack at it, will be a 300kw and ethanol , keep it very simple this time with a 0.63internal rear

forgies...and 500kws...:P

Yes and no, depends on your powergoal. You've got Matty spinning up 390kW on a dead stock motor and it also gets punished. I've sbeen how he drives it lol

So why spend thousands when a drop in NEO will cost you half the price of a basic engine rebuild?

Just my thought.

I have 2 mates that had 300rwkw 25's for the same time I did, one drivin like mine, the other PUNISHED. both of theirs were built motors from very well reputed workshops, and both of them are on their 3rd motor now. while mine was on it's second when I sold it

with these power figures its a lottery either way, so i'd just got another stocker personally.

car is dedicated E85, its a big decision, having thoughts of running a higher comp ratio of mid to high 9s, gt3076 with .63 rear internal, goal is driving on streets and drags with reducing lag and making it feel very punchy on the street. 300-320kw max

stocker- solid from factory but still old and 155av comps..

rebuild- new pistons/rings ( possibly forged) and have 180-200 comp = more grunt and earlier boost for the streets

much simpler to just drop stocker in though and maybe shave a bit off head, don't want to overcomplicate stuff

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
