Uploading some results posted from a NZ fan today. I think the NZ dyno HP determination equation is in DIN.

Latest ATR43SS2 internally gated bolted to the factory manifold on S2 RB25DET.

- Greddy knockoff plenum
- 1000cc xspurt injectors
- 80mm bar and plate intercooler
- custom 3" piping
- g4 plugin ecu

Final numbers were 331kw @ 500nm at the wheels on 18psi boost on

Hey Stao

What can you do to my old ATR43G2.5 -> Which was sent back to become a now SS2 a year or so ago. if u remember.

Is it worth sending back for some loving?

Im making a healthy 300+rwkw at the moment.

Can you get that close to your atr45? or is the housing to small for that?

Want some extra juice for Racewars next year :P

Yes can upgrade few things to make more power. I can't remember what configuration it might be in. Best email few photos first.

Cool cheers, have you got a handful of atr45 install photos? Wouldn't mind seeing the intake setups on r33

Hi Michael,

I have this turbo on my R33 - I'll post some pics below. If you want anything more specific let me know and I'll go pull the airbox off for you

Overall can't see much so it looks stock (No problems with cops). The only thing that stands out is the silicone joiner and the braided oil line for the turbo. Will be invisible with a heat shield on it.

10mm spacer was needed for it to clear the block and you will need 45mm and 55mm studs if I recall correctly for the turbo to manifold connection.

Must have a metal intake for the turbo too.

if anyone wants my #scotty_nm35 3" intake with 3" to 4" silicon reducer & an alloy extension piece (if you are deleting your AFM), it's up for sale soon...

Mine's a little different as it doesn't have the BOV return and the breather line it mounted slightly different to delete the factory hardlines, intake mates up to the factory airbox (if you need it).

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!
