Is this on an r33 or r34?

For the same given setup, will the neo make more power or are they same same?

R33 GTST. The ebay high flow failed and it was brought high flowed for the 2nd time. No hardware apart from the turbo has been changed.

^That's my car. Basic setup. R33GTST, Unopened RB25

 Hypergear 21U Highflow @ 19psi (2015 spec)

80mm stainless intake pipe

blitz return flow cooler

JJR dump/front pipe

nismo exhaust

nismo 740cc injectors

dw340lph fuel pump

adaptronic ecu

flexfuel

NPC HD organic clutch

Made 312rwkw and 474nm. The video above isn't working properly when I tried watching, here it is again. Thanks for the turbo Tao. Im extremely happy with the result.

 

Tuned at VIC DYNO HIRE.

That's mental.  Got a pic of the graph?

I do but on that run, unfortunately the tune did not have additional timing before 5000rpm. We did the power runs first as we where running out of e85 in the tank and then added the low end timing afterwards. Tuner wanted to do a final power run but I didn't want to risk it sucking some air. I also had a boost control issue, full boost should be at 3.4k but isn't arriving till 3.7k. Still trying to work out the issue there, lack of time to troubleshoot. It didn't effect top end but mid range is below what it should be. The graph shows 150rwkw at 4k, i estimate it would be around 170-180 with the extra timing but should really be closer to 190-200rwkw if the boost issue is sorted. Anyway here's the graph and yeah the car feels pretty mental with this sort of power and I'm very impressed and happy with the hypergear 21u high flow.5bda621456e5b68bb122b560776d1234.jpg

Tuner emailed me some better images of dyno graph today. The second graph is a comparison of a run with no additional timing and boost controller off. I think a proper intercooler and exhaust would definitely improve the midrange and overall torque output. These images are much clearer at least.

Updating with two more results: 

 ATR43G3SAT externally gated on E85 fuel, stock engine with supporting mods

Awesome drifting video from this car. Can anyone please advise of how to insert Youtube media into post please (like dyno run video above).

Also pretty decent power on P98 fuel. Running off an Rb30det with 264 / 272 cams using one of our custom made ATR45 turbochargers.

This is quite interesting of a job so I post. It is high flowing and converting a bush bearing BorgWarner S300 series Turbochargers to ceramic ball bearings. ATR45SS compressor is used with a matching .70 compressor housing along with original S300 turbine wheel and housing.

BB improves throttle response and maximises boost response, so the turbo makes more boost with lower rpm. Yes can use different housings depending on size of wheel used.

There is about 6 hours of engineering work required making up all the little collars, spacers, as well as modifying the bearing housing and re-grind the shaft, everything needs to be done perfect for this to work, its not a quick easy job.

This particular one cost $1400 to do thats including the BB upgrade as well the supplying the comp wheel and comp housing.

For a Normal Garrett T3x and T4x  based turbocharger in working condition with housings supplied, it will cost $650 to carry out. 

Holset or BW medium / large frame like the one above again in working condition with housings supplied will cost $1000 to carry out.

Some more data to update with. This is an result of an compressor wheel upgraded of a TD06L2 12cm based 20G P98 fuel to our ATR43SAT compressor wheel.

I will keep this thread synchronized with our FB updates.

This is based on an prototype SS2 running ceramic ball bearing core. The new housing has been shorted so the dump pipe is no longer been pushed back against the A/C drain. Turbocharger made 302rwkws @ 21psi P98 fuel internally gated as a bolton turbo. Currently 18kws short of the target goal. Project is still under development.

Hey Hypergear 

Wondering what you think one of your 21U high flows would work like on an FJ20 4 Cylinder 

I'm looking to keep the stock T3 manifold as it's an engineered car, hoping to make a responsive 220ish kws on 98

Any help would be great thanks

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
