Stao, Are you able to replace the oil seals in a Garrett 3582R? if so how much do you charge for this?

The Oil seal on exhaust side is just a Stainless steel C clip. This part only wears when you have abnormal amount of shaft play or if its submerged into engine oil means you have a flooded bearing housing.

So if you have no shaft play then the only thing I would be checking is the drain or find out why my oil can't drain out of the bearing housing considering I have 20mm drain slot vs 20 thou oil feeding ports.

The other thing which can cause that is from over filled engine. Ie: Oil level in engine sump submerges the drain port which build up oil in side the drain pipe to cause bearing housing flood.

Also does the turbo make any sort of strange noises on power off? Ie. very light zz zz zzzz zz sort of sound?

If do exists and every thing engine side seems to be nominal then you might want to remove the turbo and send it in or take it to a convince turbo service center for a quick inspection.

Few more updates made for the ATR43 and PU high flows .82 turbine housings. They now installed with 33mm wastegate flap working with a 30mm internal gate port. ( 2mm+ for the flap, 1mm+ for the port). Not much of effect with RB20/25dets, but will make lot better boost control for larger sized engines.

Also this is a little unconventional method creating slight boost spike or consistent boost curve upon to red line. fixing the issue of slight boost drop due to actuator's sping strength. It is updated into all ATR43 / PU high flowed turbos, I found it particularly useful for people who's looking to hold 20~22psi with internal wastegate actuator.

Photos showing:

Wastegate can be fully operated by actuator

or partially operated.

This is a photo for people who prefer to DIY their own actuator bracket. This is modification is included as a part of our high flow service. This post is for people who didn't sent in their actuators.

basically drill or file fitting wholes 5mms towards turbine housing. Once done the factory actautor can be pre-loaded or adjusted.

Stao few questions what type of vband clamp is used for my dumnp? i need to get another one quick. also will a r32 actuator fit on my car? i want to lower the boost to 10psi had a little delay in getting injectors sorted but want to start tuning

Its a 3inch Stainless steel Vband. You can get it from your local exhaust places for about $40.

If you run stock actuator you should be able to drop some boost. But ATR43's comp housings doesn't have OEM actuator bracket pattern so installing it on the car would be abit of challenge. Can be done.

what would it mean if it made that sound? i recon my old car may have done that..

Normally means there are small cracks or uneven surfaces on rolling objects. It's the early stage of failing. This noise do gets louder with time. It is recommended to have the turbo overhauled at this stage. It will be very difficult and expansive to overhaul once wheels scrubs.

Oil contamination would be the main cause of it. Run a small inline filter before putting the turbo back.

thanks for the quick answers stao

hey if i was to get an atr43G3 and wanted to run about 18psi on my r34 gtt rb25det neo at wat rpm would it have full boost (18psi)?

how much power do you think it would make with all supporting mods at this amount of boost?

and is a z32 afm a good idea to get first, its the only other thing i need that i dont have..

thanks =)

With ATR43G3 .82 you will get full boost at 4300RPMs. With the current waste gating control you should be able to get 300rwkws on 22psi flat with supporting mods.

In most cases you will get some where between 270~280rwkws on 18psi.

Supporting mods you are recommended to get:

850cc injectors

Z32 AFM

ECU (Nistune or PFC)

Cooler, clutch, exhaust and all usual stuff.

ive got all the usual stuff

ARC FMIC

full exhaust

apexi pfc

oil cooler

clutch

splitfire coil packs

apexi avcr

ive also got denso 670cc injectors not installed yet, their on a custom rail for the r34 GTT, they will b enough hopefully wouldnt they..

apart from the z32 which i should be able to get soon enough

670cc should be fine for that turbo

670cc = 670hp = 500kw (at the fly) - you're running 98 i assume, so those very rough calculations would be about right.

With all the bits installed and a good tune. you will be able to get 270rwkws pretty easily running ATR43G3 .82 turbine on 18psi.

Also for Actuator DIY people. This is a alternative method of getting 12psi without boost controller. I've personally managed 14psi tops. This extender arm is for $25 for who ever needs it. You need to cut and thread factory actuator’s connection rod to get it installed.

This is a reading out of a PU high flowed turbo in Max power profile based in .82 bolton turbine housing. Made 290rwkws on 19psi. The car's dyno tuned straight turbo installation which is supposedly to be tuned after 200KMs of driving. So the actual curve should be shifted by 300RPM or 8.5KM/H to the left after run in.

I think it can squeeze out another 30kws on 22psi. Customer's very concert about his engine so we left as it is.

Its a 95 R33. Car's got PFC, 550cc injectors, Z32 AFM, 3inch exhaust, cooler and usual stuff.

So 300rwkws on stock comp housing that looks EPA legal is achievable.

Very nice, so is this the ATR3G4 wheel? Or is it similar to the 3576 like I have ordered?

So what is the advantage of running the atr43 if this is hitting 290kw? What revs did this hit full boost at?

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
