Thanks mate, thats exactly the info im after.

It is a 25. i will go ahead with the original plan then but a g3 then

 

how does a G3 compare to SS2? im not sure what the name of the profile actually mean. as you said its a little confusing on the site.

ATR43SS2 is a brand new turbo that is capable of making more power.  Ball bearing option is highly recommended. It is also highly recommended  working  with our externally gated turbine housing kit.

Regarding to Rb20det highflows or builds from earlier discussion, they runs a smaller turbine and and compressor then a RB25det turbos. Can build it into a OP6 it would work similar to a HKS2530 with a modern wheel set for more power. Its not a bad choice. 

Sharing another result. This is an ATR43SS2 on Pump 98 fuel making a pretty responsive 355rwkws @ 20psi.

Sharing a pretty interesting result from a Rb20DET with Rb25det Neo Vct cams. Turbo's one of our ATR43-G2 BB model for RB20det in T3 .63 rear housing. Car managed to pull a pretty responsive 321rwkws on E85 fuel externally gated.

 Engine's in a Ford AU :D. Pretty interesting eposide to watch:

Updating this thread as some of yous would have seen on FB. Not about turbos this time, but a piece of information for people seeking the Rb2530det rout.  

I've attached results of my built Rb25det with Kelford cams Vs my built Rb30det with HKS cams, making it a reasonable comparison of what Rb25det Vs Rb30det is like. Both engines had identical setups, E85 fuel, made the same power, while the Rb30det was 1300RPM better in response, more power every where and 137Mn of extra torque.

I’ve also attached result of differences HKS cams made in comparison to stock Rb25det cams on the Rb2530det engine.

Thank you for posting here as well Tao! I'm not following social media so I very much appreciate it.

Though in some ways I'm not sure if it is good that you keep posting these promising results :D You are the voice of temptation.

Updating result:
 
R33’s back at Chequered tuning for with another of my in-house built specials. Car had no other changes apart from the turbocharger, we managed to get:
 
516rwkws @ 26psi
569rwkws @ 29psi
606rwkws @ 30psi
642rwkws @ 34psi
 
Turbo’s holding boost with pretty consistent gain per additional PSI of pressure is added. Unfortunately my 3 bars Haltech Map sensor (vacuum is a bar) was very maxed, be back on the dyno to max out this turbo once new sensor arrives. Pretty successful day over all.

Updating result, This is from our latest ATR45SS-3 model, Its made for 100bhp applications. Same car as above. It managed to pull 636rwkws at 34psi.  Drive ability wise, car hits 300rwkws by 4K and 450rwkws with 1014Mn of torque by 4250 RPM. Pretty good to drive with crazy amount of mid range torque.

Run against ATR43SS-3ProR turbo from earlier.

hey guys

so i wana make 250-260kw atw on my rb25det, would the g2 be capable of making that power goal or do i need the g3? just kinda confused because on the site it says its capable of 350hp but doesn't say if its meant for an rb20 or if its suitable to make 350 on an rb25.

ill be running 550cc side feeds, a walbro 460, frontmount IC and all the other stuff necessary

cheers

Hi, G3 profile with Rb25det turbo housings will be fine for around 270rwkws on Pump 98 fuel internally gated. I can supply donor housings if interested. To make the power you will need 3 inches metal induction pipe, 600x300x100mm front mount cooler, at least 3 inches turbo back exhaust, programmable ecu, along with injectors, fuel pump, you've got.

Stao, 

Just managed to get my hands on a GTI-R pulsar. I want a snappy 400 awhp, on stock stroke. Will do camshafts if required. What do you recommend?

 

Hi, on E85 fuel and internal gate, 54mm ATR28SS15 in T2 .64 rear housing will do nicely. I've used BC Step 2 (272dur /12mm) on SR20det for 300rwkws+ applications

    • Gosh these bmw's are worse money pits than JDM's! I won't complain about my car anymore 😂
    • I'll just leave this quick tip here after reading your joys of getting the car in the air. It should take no more then 10 minutes to get the car safely up on stands.  So for the front, jack on the tow recovery points (marked in red). Put the jack stands under the lower control arm mounting point (marked in yellow). This photo is of a R34 GTR, however the process is the same. For the rear, jack under the diff (marked in red). Put the jack stands under the rear subframe or where the lower control arm mounting point (marked in yellow). Which point you use will depend on your stand, pick a nice stable point.  You've probably already read this but it's worth repeating. When jacking up the car or using stands, stay away from the chassis rails/pinch welds. Even the factory jack point, stay away from that too unless using a factory jack. I used those jack points for years without issue until I turned into an old man and bought a QuickJack lol.

    • Hi all, From the western suburbs here. Just got my 2000 R34 GTT registered today! Got it imported from Japan through a mate who is doing them and managed to find a decent one. This one has only done 110,000 Km and had no body rust etc. so was very happy. I used to own a 25Gt back in 2015 (ate Ramen noodles for years to save up for it), but unfortunately, it got stolen TEN DAYS after I bought it!! Came back from Uni and the car was missing - cops found it in Springvale a month later with a lot of needles  😒 It was too late by then and I had moved on to a different car (300ZX), and after that one got broken into around 2018, I was in a very bad place and decided I would never buy a car again because it was just pointless!!! ~yeah, I have some very bad mojo~ 🥺 But now, with a stable job and a secure garage, I thought I'd get the R34 4D again but not as a daily! I love the R34s but a GTR is still a bit off my pay grade so settled for the GTT instead.    The first step for me is to get this car serviced and have all fluids, belts and spark plugs changed. I might do the brakes at one point too but atm they are fine, the fluids are what I want changed since this car probably sat in a garage for a long time. I'll then get some coilovers since the suspension needs to be changed anyway (the dust cover kit is disintegrating). I'll also upgrade my car alarm to a Viper system and then look at rims and tyres (I'm a sucker for TE37s - might have enough saved in another 3 years for that).   Today: I was planning to do the oil, coolant, air filter and fuel filter change this week. Started on the oil change today and MY GOD what a pain!! I used to think the 300ZX engine bay was cramped - oh I was so wrong! 😂 I've done the usual services on my cars before so it was not like I was going in blind. I looked up all the forum details about what oils to use, what coolant to use, what points to use to jack the car or place stands etc but I did not expect it to be this hard. Long story short - all I managed to do was the oil and filter change. I think I might end up taking it to a mechanic for a coolant change because my SCA stands and trolley jack just can't get far enough underneath to the cross-member and I don't want to be crushed under my favourite car....yet. Side note: In Dandenong, there used to be a shop that lets you hire their hoists - does anyone know if they have those around? I can't seem to find the Dandenong place anymore. I contacted them off FB almost 6 years ago and I'm not in it now. If anyone know of one, that would save me some time going to a mechanic for the basic services. Oil: Dark and gooey but no metal pieces. Oil Filter: Was a b***h to take off but no red flags Air filter: Yucky! Was black (Smells like fuel which makes me think it may have been running rich? - am I way off?)   Concerns: I have but one concern atm and that is that there was a very small amount of oil leaking where the engine and the transmission connect (Automatic). It may be the rear seal? It's not a massive leak and it does not affect the oil pressures or leak oil all along the driveway. It's been falling into the cover this whole time. I've taken the cover off so I can check the garage floor from time to time.  I also have not seen my engine temperature gauge ever sit at cold and slowly move up to the right spot, but that might be because every time I saw the car today, it was running. I'll check that again tomorrow. ATM it just sits right in the middle. I may just be paranoid but I don't want an overheating engine while my gauges say everything is fine. 🙈 Other than that, I'm very happy with the car! Feels like it's about time I went back to spending my weekends driving or cutting my arm on stupid sh*t in the engine bay.   PS: I will post a pic later on because I underestimated soooo badly today and it was dark by the time I finished! PPS: I broke the two damn plastic pins that hold the intake funnel section to the front bar. This is the piece made to bring cold air to the airbox. The connection to the airbox is fone, but the two clips just broke off! Should I be worried? Anyone else done that?
