Looks good, some wheels would really set it off. Is that a carbon cover for the rear seat area?

I've got a r34 neo turbo as well, the original turbo crapped out and my friend had a neo one available so I used it. The compressor is the same but the turbine housing is considerably bigger. The wheel also has different number of fins and is made from a different material. Spools slightly slower than the standard turbo but has slightly better top end... I havent tested to see if these are prone to snapping wheels off like the older turbos but I spike 16 and boost 15 regularly and its been fine so far. It is a direct bolt on, only other difference was the wastegate nipple points in a different direction. These are my personal findings so far on the r34 neo turbo.

I'm pretty sure all the RB25 turbos are the same size, and the only difference is the new ones have nylon compressor wheels which should in theory make them spool just a touch faster. That's what all the guys with stock turbo's and dyno graphs show on Skylinesaustralia.com at least. Not certain though, so don't take it as gospel.

It's damn good to see somebody mounting aftermarket safety harnesses correctly though. I can see you enjoy the use of your spine Nice clean looking car man, I like it.

maybe, i dont know. check out what this guy told me:

"I've got a r34 neo turbo as well, the original turbo crapped out and my friend had a neo one available so I used it. The compressor is the same but the turbine housing is considerably bigger.

so im not sure if you or he is right. what do you mean by mounting the harnesses right? ive heard a couple people say that...

Now I know that dude is full if it about the turbo. They ALL come with ceramic turbine wheels. People got confused about the fact that from the newer on up (kouki) RB25's, they had a nylon compressor wheel, and some how that got turned into the common "internet fact" that the turbine wheel was made out of steel. Now you might have a VG30 turbo or something like that. They have a bigger exhaust housing/wheel. I think some of those might have steel wheels, but I'm not speaking from first hand experience there.

About the harness, a lot of people just got over the top of the seat and right down to the floor. If you do this and come to a sudden stop which would actaully require the use of your 5 point harness, thanks to the geometry, it'll compress your spine straight down instead of just holding you from going forward. You have to have the bar behind the seat at shoulder level, just like you do. There have been instances (I've read about, not seen) where people have seriously hurt there back getting in low speed fender benders by wearing 5 points incorrectly installed.

The material could very well be the same, they just had a different color to them (oil, egts, wear and tear) so I assumed it could have changed since the turbine housing was a different size, i didn't go into doing a test to see the composition of the wheels, frankly its a stock replacement turbo and I could care less. I assure you the turbo I used has a larger A/R housing then the standard 25 turbo this along with the discoloration led me to think its possible they switched materials. Or it could be I got a wierd turbo which someone claimed was a neo turbo which perfectly bolted on to the stock manifold/dpipe/intercooler outlet and it had a different housing which I am assuming is a neo. Regardless none of what I said if from the "internetz", its from what I saw on my own car so spare me your elitist bulls***.

EDIT: quick thing I pulled from the internetz while were at it since I being accused of a internet regurgitator

Changes to the engine included a new NEO head which contains solid lifters and revised variable valve timing A slightly larger exhaust housing on the turbo is used to improve flow, and the compressor wheel is now made of Nylon to reduce lag. A larger side mounted intercooler was also added and is efficient for levels up-to 200rwkw. Acceleration times remain similar to the nissan skyline R33 as it is a slightly heavier car.

I agree that the harness bar is in a decent location, but I would NEVER have more than the standard 3-point belt without a 4-point "cage" at minimum. If you roll a car without a cage and you have harnesses keeping you positioned upright, your head has nowhere to go but be smashed down by the roof. With a 3-point, at least your body will rotate to a side and hopefully out of harm's way. That's MHO.
