Hi guys,

I will be swapping my R32's cooked transfer case for a fresh one within the fortnight. I have not come across much information on SAU in relation to swapping the transfer case.

Can anyone who has done so offer any advice/tips on doing so?

Are there any parts that need to be replaced? eg washers, o-rings or anything alike?

From what I am aware of at present to get the gearbox out I have to remove and install the following:

1. Speedometer cable

2. Front propeller shaft

3. Clutch slave cylinder

4. Starter motor

5. Gear stick

6. Reverse lights plug

7. Exhaust (from the front pipe or from the dumps?)

8. E-TS hydraulic air bleeder actuator

9. Gearbox obviously

Removing the transfer case from the gearbox?

I don't have all the details but it was pretty straightforward once the box is out

The hardest part was the shifter, there is a rod from the transfer case where the shifter goes down to the gearbox it was fidly. The transfer case is just bolted on from memory, not sure if there was a gasket.

All the details would be in the workshop manual

Cheers for the response Duncan.

As I am attempting this in the driveway (backyard love :)) I would like to attempt to remove and replace the transfer case without taking the gearbox out (heavy bastard), eg I would prefer remove gearbox x-member/prop shaft and tailshaft to tilt the motor/box backwards towards the firewall thus giving me access to the top of the transfer case.

Has anyone attempted this with success?

I'm pretty sure you won't be able to do it, all the fiddly stuff is on top of the transfer case, even if you get your hand up there chances are you will drop the pin or rod into the box :P easier to take it off I reckon.

Would be interested to hear the trick if someone knows one :)

I've taken the transfer case off my busted gear box. Definately possible only with gearbox out of car.

Once you see the bolt and roll pins you have to remove in top of transfer case opening you will see what I mean. 1/2 hour job to pull apart with basic tools.

Box has to come down, no gasket, just use gearbox gasket goo. It's a good idea to change the selector shaft seal. Like others said its fairly straight forward when the box is on the ground. Pull the top cover off and knock the rollpin out enough so you can release the selector shaft.

Its a bitch to R+R the box off the car on the floor though much easier with a hoist and a tranny jack.

Drain the oil ouf of both before removing and dont forget to bleed the attessa.

You dont have to remove the dumps ( just as well they would be impossible to remove on the car), just the front pipes.

I just had my car up on the hoist and it appears my transmission fluid is leaking out of my transfer case somewhere. The mechanic couldn't pin point it exactly as obviously it sprays everywhere when driving but it appeared to be leaking out of where the front driveshaft connects and even possibly at a hydraulic hose at the rear of the transfer case.

Hopefully the box doesn't have to come out for this.

Hey dude, just wondering if you know the part number for the selector shaft seal?

      Let's hope that's not a copy pump either. There were so many copies of them back in the day.

      Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys

      Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.
