Whats so shit about the 20 box? They are under rated IMHO.

For the 25 box install, you need a custom tailshaft thats about the length of the 20 shaft but with a 25 yoke to suit the gearbox output shaft. Measure it on the car to be sure you have the lengths right.

You need to muck around with speedo drives and there's a bit of playing around with the crossmember.

There are a fair few threads floating around covering this topic with a fair bit of detail on speedo drive conversions and tailshafts.

OK cross member depend on what you have in the car at the moment if you go from auto to manuel in an r32 with the rb20 gearbox you need an s13 xmember but from an auto to manuel r33 box you use the auto x member the mounting points are different from auto to manuel .In your case being already an manuel when I did my reseach for my conversion I was told the original manuel one fits well maybe just a little modification. It all depends what your car was b4 the rb26 went in

If your R32 started life as an auto, apparently theres no need for xmember butchery.

If your R32 started life as a manual then there's no way around it. You have to butcher the std xmember.

Mine chewed third gear. But the box had done 200,000km's odd and had 4years of my slapping of gears. What was scary is I was hardly giving it much when it let go so it can happen any time really.. On a long trip. :S

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
