new to skylines been into silvias for years but decided to build a r32 drifter.

im going to cut the crap but basically i bought a r32 rwd with a blown box only to find out it is actually a gtst4 chassis with the 4wd box that had been chopped/ changed to suit rwd application.

all the paperwork says that it is a rb20det rwd, so perhaps the car was imported like this? despite being caught off guard with a really f**king heavy gearbox i got it removed.

now i have a few questions:

there was a hydraulic line at the back of the gearbox when disconnected it leaked what looked like power steering fluid. is this connected to the hi-cas?

the x-member for the gtst4 and gtst are completely different. will i need to custom make one? can you buy conversion plates?

is there anything else that will not bolt up along the drivetrain like the diff? (already bought a r32 tail shaft because the 4wd box is different again pinch.gif)

The line going to the back is for the attessa 4 wheel drive system. The pump is above the rear diff and the reservoir is in the boot on the right hand side.

There is only a few crossmembers for skylines so im sure u will be able to find one that will fit.

Which cross member are you talking about? The main one under the engine is very very different between the 2wd and 4wd chassis, and you can't swap them between. But that's no problem as the one in the 4wd chassis is much better (stronger - it's basically the same as the GTR) anyway. You just bolt the engine mounts to it and away you go.

But if it's the gearbox crossmember that you're talking about - then yes, you will need to make something. I haven't looked closely, but don't think there's an easy way to sling a RWD gearbox mount from there.

thats good to hear, ill have to double check that it is a GTR engine cross member would be good to know since its going to be a track car.

Ive seen both the 4wd gearbox and rwd cross member lined up and they are completely different. im going to bolt the gearbox up and hopfully pin point where the holes line up on the 4wd drill/chop/change to suit :P

either that or weld up a new bracket for it. not difficult to do just thought id check here first before i mutilate anything!

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Stock Airbox and Snorkle for RWC - VIC west

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      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?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      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.
