Fits up nice, no probs.

Wastegate is nice and free now, car goes fine, seems like no damage. Battery still good.

Sweet.

Ooh... is that a Mild Steel Bellmouth?
When you've put it on, you wanna put my Stainless Bellmouth on for me? :D

Mild steel.. just as good, maybe better as anyone can weld it if theres any probs or mods.

Depends..... if its from the same factory as my stainless split, you can chuck it in the bin now and save yourself a huge hassle.

Or its a breeze when it fits like the new one, Just jap said the mild steel bellmouth is made here, and the stainless split was China.

Stainless Bellmouth courtesy of JJR !!! Figured for an extra $20 I'd get the Stainless to match the rest of my Zaust.

Does your car go any better or sound any different?

nope, same

if you think about it, the split doesnt make more power or anything cos the gate is shut with throttle on anyway...

Just thought it might flow a bit better and maybe sound a bit deeper / louder etc.

Wouldn't the gate be open at wide open throttle?

No, its shut making boost (mostly anyway) and as the pressure climbs, it pushes on the wastegate actuator, opening the gate and dropping the pressure.

The wastegate allows hot gasses to pass by the exhaust turbine without pushing it around.

When the gate is shut all the exhaust energy is pushing through the turbo, and spins the compressor making boost.

I didnt know any of this 2 years ago, SAU educates.

Yeah that's sorta what I mean, as in...

say if you have a 10psi actuator on your turbo and you floor it, the actuator is holding the gate shut until you reach 10psi (which takes no time at all) but then at that 10psi air pressure the actuator opens the gate to bypass the exhaust wheel and stop overboosting, giving you a constant 10psi of boost. Meaning that from say 3000 rpm to gearchange, the gate is open and both outputs of the turbo are releasing the exhaust gases into the dump.

whether it's a stock dump, split dump or bellmouth, but being that both outputs are pumping into the larger chamber of the bellmouth, I thought it might sound a bit fatter.

When I get my Bellmouth on, it will be an upgrade from the stock dump with a 3" frontpipe, where as you have gone from an aftermarket split dump to the Bellmouth which may not be as drastic a change power wise.

and yes SAU does educate but can also be quite misleading at times...

4WD/2WD button installed.

Lights up BLUE off (4WD) and RED on (2WD)

been meaning to do this for a number of years. Procrastination at its best.

Originally had a HKS Torque/Drag controller in her but that was put to better use in a 9.3 second GTR.

Niiiiice. This is a massive advantage of the R32's ATTESSA system in my opinion. lol. The ability to electronically switch to RWD mode without having to drop the front driveshaft.

Used it to jump start my Fozza. Took Fozza for a spin around the block.

Some white smoke coming out of engine bay. I am hoping it is just from dust etc. from sitting still for so long.

Going to hit the engine with some degreaser and hose it out tomorrow. See if that clears it up.

Ta Troy - it is fairly awesome

Anthony - Well you haven't smoked up the rear tyres then - lol -> (hoonish)

quick pix

note also the 4WD light comes up on the dash

Nope. Car is still to new im scared ill break it!!!!

Edit: spent 4 hours the other day trouble shooting my HICAS. Previous owner butchered it pretty hardcore. Turns out it has an electronic bypass using a switch. However the wiring was done so badly it can't be recovered. On top of that my rims are too big and will rub if i turn it back on. So im just going to remove the bulb of the warning light. And WHEN i find a job ill look into options...

Overboost again...

So ill wait for it to cool down and change the actuator back to the old one and the bov too.

Brown sludge in the radiator? wtf? i just cleaned it all out. maybe the head bolts needs a re-torque after all the overboosting. maybe the turbo seals are going.

Brown sludge is pretty common in skyline cooling systems, try flushing the motor and rad 1st, its easier than headstuds :)

WHen i replaced my manifold coolant hoses the other day they were 1/2 solid due to the crud build-up in them as it clearly hadnt been flushed ever lol.

Washed and Vac'd my car today. Also did a few little things in the engine bay, still pretty messy though :/

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
