So I'm doing an RB26 conversion on my S13. I have spent all my money on the engine setup and don't want to spend money on an R33 gearbox when I have 2x r32 GTR boxes sitting here already.

I've removed the transfer case already and all the internals that seem associated with it. What do I do in terms of the oil pump in the rear?

Any info from someone that has done this would be much appreciated.

cheers,

Greg

i guess u cud bin bits and stuff around with removing the transfercase to save weight.

but just remove the front drive shaft between the transfer case nd front diff, nd u mite need a custom tailshaft/ use da gtr one if its da same length as the s13 driveshaft

All the inners that are associated with the transfer case have already been removed and the transfer case has been cut off as it probably wouldn't fit in the S13 tunnel with it still attached.

I have done it in my GTR, car is running 630rwhp and loving it.

I welded up the hole left by cutting off the tranfere case with 10mm ally plate then surfaced the gearbox and the tranfere case to be a perfect fit. I then put a litre of diff oil in the tranfere case which with acceleration and decelleration should keep the bearing oiled, they are not noisy yet and that included a thrashing all weekend at powercruise.

One thing to watch out for is make sure tou put the selector pivot back on the selector shaft the right way up, otherwise you will be pulling it apart to do it later, its simple mistake if your not paying attention. ie I did it on mine at around 2am when I should have been in bed instead of working on cars haha.

The oil pump is only there to clamp the wet clutch for the 4WD system. So the short answer is bin it.

incorrect you need it to lube the rear bearings. I have done about 6 of these now greg if you need one done. i just did one for type M in dandy.

this is one of many threads ive posted pics.

What's your number Trent?

I also need the motor built and I'm over waiting around for people.

Sorry my bad.

I assumed you were referring to the ATTESSA pump that plugs intot he back of the gearbox/transfer case.

The internal oil pump inside the gearbox should be kept.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
