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.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
