This question has stumped me as i have no idea what cross member to get

Im trying to put a RB20DET manual gearbox into my factory Auto Laurel.

I havent looked at the differences between a auto floor pan and manual one to see if there are any differences between bolt spacings, ect

But i still havent a clue which one to get!

Parts thread says this;

Gearbox

Replacement

RWD - RB20, R32 Skyline GTST (1989 - 1994)

AWD - RB20, R32 Skyline GTS4/GTR (1989 - 1994)

Upgrade (info on what is required, HERE: http://www.skylinesaustralia.com/forums/Rb...ff-t103164.html, and HERE: http://www.skylinesaustralia.com/forums/Rb...4#entry1898084)

RWD - RB25, R33 Skyline GTST

AWD - RB25, R33 Skyline GTS4/GTR (1993 - 1998)

yeah im trying to look for the same answers but im putting in a 25 box in mine if im reading this right seems i would be ably to use the cross member from my auto box and use it on my manual one with no modding ??

Everyone's side of this story is different.

Try whatever you've got laying, if it doesn't work, you can get one made up from scratch with an engineer's certificate for around $300 give or take.

Or get your dodgey mate with a welder to fab that shit up himself....whichever.

yeah its hard to tell i dont really wanna spend $300 on a x member guess im gonna have to do a bit more digging

by the way as you seem to be in the know :) ceffy manual hand break cable fit lc33 laurel?? yes/no?

auto and manual bodies are different, that being the shifter hole on a manual body is about 60 ish mm further forward, and same with the gearbox mounting, this applies to both cefiro and laurel

for my conversion I used a s14 manual x member (RB20 box)

Edited by VRdrift

alright so wonder if this affects the shifting gears once its manual guess can always cut the hole larger if need be...

im guessing the rb20 box would not be the same size as the rb25 has any one out there put a 25 box in a auto laurel and what x member was used?

pretty sure the factory r33 box's x member is used for that, you won't need to cut the hole bigger, shifter does not foul anything it just sits offset in the hole, and the shifter boot you just turn it around backwards bolt it up and looks factory

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
