Easiest way is to tap a thread behind the actuator on the transfer case and use a bolt to pre load it.

Expensive way is the t case mod by changing the plates.

i love how this post give all the right answers and was completely ignored

Yes i agree that the post has some good and bad idea. But its intresting to see the ideas that we all have. Some are not practical at all but opens the door to understanding peoples point of views. Even though some makes no sense. Kind of like on any topic. Some will always sound crazy.

But here what happened to me.so far i changed the whole attessa pump. And man. I cant see a difference now between reaction time from my r33 gtr to this gts4. All i have now is traction. And yes all i do is drag race, i know lost of the guys here circuit race but some if not lost of things are common. I cant believe the difference this attessa pump made. When i was bleeding it up i noticed the difference right away. The manner in which the pump sounds and the pressure on the line. Now when i drive if i go on the gas a bit and bring in just a little bit of boost the front torque split gauge starts to move up to about 15% and now my 4wd light stays off on start up every time. Before it would come on. Then id have to stop cut the car off and restart it.

From the r33 to r32 i can without a doubt mension tye difference. First the r33 gtr is more relaxed for exsample. R32 whiles driving tends to always apply the front wheels on the r33 gtr this doesn't happen unless there is a slip condition.

Im still going to rebuild my transfercase and when these driven and drive plates come from greenline. (Much thanks there guys) next im working on have the manual engagement system worked out, but im going to install it in my r32 gtr. (Bare wit me it get confusing because i have a few cars i mess with.)

This gts4 chassis i experiment wit.

Thanks for all the ideas guys. Keep them coming. And if anyone has info where i can get a good manual system from please PM me. Thanks.

Talk to Robbie at RIPS, they run some sort of manualised system in their drag cars.

You can sort of see it in this vid-

That's Glenn Suckling's R32 which he bought and put one of his 3.2 Nitto engines in.

Lol. No i dont think ill be doing that bolt mod. But i have ordered a set of friction plates and drive disks from greenline.

I hope these guys are for real and i dont have to visit them. After i paid no one is answering my emails. I wouldn't do business with them again.

If the disk do arrive i will rebuild the T-CASE. And try the manual system here is my first part that arrived. Attached photo.

I will get this to work. Im looking for the hydraulic pressure used for full lock on the T case. ???

I was trying to find the pressure from a video by looking at the gauge, but the image isn't clear enough.

Robbie from RIPS has bought the car and is now dragging it. You could try an email - you might get a reply or not?!

I looked into it, apparently 220psi stock. I was looking to bump that pressure up a bit in the Stagea.

I have done this mod to several track cars I used to work on and feedback was that it worked extremely well.

Something to be aware of though is that for a street car this wouldn't work all that well as it does leave the transfer case prelaoded at all times. You need to get under the car and adjust it as well, though adjustment is very easy given its just a bolt and locking nut.

I have finally gotten a set of these disk from rhdjapan. FYI i spoke to mr. Hobbs and had him place the items on there site. (Search by part number) I was really suprised at how fast he got them to me.

This week i will be pulling the box out and ripping it apart (T-case) to replace these friction disks. I cant wait. Then ill focus on doing the manual pump system. I just wish there was a kit out there to buy from a store. If it gets to complicated for me ill just go get the torque split controller.

Hmm. It was very easy to do. I just didnt change all the seals that most recommend. No leaks so far. I see what most said. Dont add the disk and block the oil drain holes in the friction disks drum.

My mistake was that i didnt soke the disk in oil before installing them. Notice it locked up in 4wd wit no oil. So we didnt want to take it all apart and came up with the idea to take the engagement piston out, then it started to free spin. So we added oil and spin it free hand as well as drowning it in oil making sure we wasted money buying oil and having the whole friction disk area soke in oil. (Dumb). we then measure the clearance and we were at the minimum of .008. Once soked wit oil we still couldn't free spin it by hand. But sure with front wheel resistance it will free spin.???

Here is some photo's

Very simple to do so far.

The old disk were good but just a bit worn. I measured it before disassembling it and it was over .020 inch. Sorry for that. So definitely at .008 its within factory standard.

Damn no one is intrested in this post it seems like. :(

Well i just bought the ETS PRO from fullrace. Cost 660 usd dilivered.

I found some info saying the samething someone said here. I can put it in manual mode and full 4wd lock and let it rip. Then at high speed go 2wd.

Im just trying to think of a way i can get it to go into 2wd automatically???

Brain buster.

Any ideas. ???

Just off the top of my head, you would probably need to run a circuit from your wheel speed sensor circuit to your pump/ controller. Or some setup from the G sensor signal or both. But aren't you using a manual override anyway?

    • 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
