That is the CHRA that we normally use for GTR turbocharger high flowing. We will need your factory housings to carry it out. Or we can supply you 2x complete Garrett turbos. I will PM you a quote tomorrow.

so we can run the turbos with no blow of vavle?? by blocking up our stock one?

When i got my car it had been defected for an atmo bov so the previous owner had just blocked off the hole where the bov was, still seemed fine to me.

It is strongly recommended that you do keep a BOV. stock or aftermarket. The Surge pressure that comes back when throttle is shut can do lot of damages to the turbo.

Below is the commercial version of ATR43. This is now available. The turbo comes in 4x different profiles:

atr43rear.jpg

ATR43G1: 450HP in . 58 / .63 rear

ATR43G2: 480HP in . 58 / .63 rear

ATR43G3: 520HP in .63 Rear

ATR43G4: 600HP in .84 rear

It is designed to bolton to your stock manifold, dump, water, and oil drain. Braided oil feeding line is required and priced at $80 with turbo. All turbos can be built with a Garrett GT Ball bearing CHRA depends on consumer's budget. To fit them to factory intake and intercooler pipes you will also need 2x silicon pipes one in 90 degrees 2inch and the other in 3inch straight.

ATR43's .58 and .63 Turbine housing is interchangeable with All ATR28Gx High flows that we've sold. Will gain instant power increasement specially to the ATR28G2 based R32 / R33 xIU high flows, Should have No issues archive upto 270rwkws with supporting moods.

The stock oil feeding line has a oil restriction valve. It is not suitable for sleeve bearing CHRAs. Also Garrett GT CHRAs runs off a different thread.

Sleeve bearing turbo require greater amount of oil flow. The bearings needs oil pressure to float. BB does not. BB turbos has roughly 10% better in response. Sleeve bearing turbos are cheaper to build and service.

ATR43Gx are made to be interchangeable with Garrett GT3071, GT3076, and GT3582 GT CHRAs.

So really comes down on the consumer's budget.

ATR43G1: 450HP in . 58 / .63 rear

ATR43G2: 480HP in . 58 / .63 rear

ATR43G3: 520HP in .63 Rear

ATR43G4: 600HP in .84 rear

Are these figures rear wheel or fly wheel?

What is the price for the G3 and G4 in both sleeve and bb?

those are fly figures, which i think is the standard way manu's spec their turbo's

I assumed that, just wanna be 100% sure.

What is the price to rebuild a set of GTR turbos in both bearing forms?

To high flow GTR turbo using GT2860RS BB CHRA is $1350 each. And we can supply the Garrett unit brand new for $1400 so might not really be worth doing. To high flow with Sleeve bearing CHRA in identical spec is $800 each turbo.

How much are the ATR43G3: 520HP in .63 Rear and the ATR43G4: 600HP in .84 rear for the rb25det, when should you be able to see full boost? and what is required for a direct bolt on to the rb25det?

Hmm, interested to see how the ATR43G3 with the .63 Rear would go on an RB20, how would it compare to say a 3071r?

I'm currently running a highflowed VG30 but looking for a little more power than it's currently making.

um be careful quoting prices here, this isn't trader / for sale?

are there any issues with cooking the bearings at engine power off vs ball bearing?

He is a business trader and this thread was set up by him to tell everyone about his products, i dont see a dilemma with putting up prices.

Thats all cool. If I'm bending any rules I will fix it up. From experience BB turbos are more likely to get cooked. Most sleeve bearing turbos receives greater amount of oil flow and this is built built water cooled. So they are pretty fine.

The current Ball bearing turbos runs oil feeding pins on the top with 20thou wholes on both side, Not sure why Garrett designed it that way. But in lot of cases they gets filled from dirt in engine oil which allow bearings to cook. Then they becomes very expansive to overhaul. about 80% of Ball bearing overhaul jobs we currently getting has failed in that manner.

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
