yeah I can figure whatyou have there. That's not too bad but I'd still probably have somehow found a spot for the surge tank under the car somewhere.

You have to take the gloss off the pump and filter too... it's hideously bright! LOL

Thought it was a good idea at the time to beat-box with shaving cream on my face, until it started snowing.

So the original gemini tubes fit into the borg warner housing as they measured like 1mm to small to me. It would have been a lot easyier to do it that way then the way I did it :oops: As for cutting in that works ok in a van but in a sedan or coupe the tunnels for the arms would be right under the rear seat which is not legal over here my engineer said it would be ok if I took the seat out though.

No they dont fit in, the gemini tube is flared to the same I/D as the borg warner tubes, then a tube is pushed inside of the B/W tubes and the gemini outer tubes is then pushed over that. The two tubes are welded at the join and drilled and plug welded also.

Ok I see so it has a spigot on the inside of the tubes sounds like just as much work as what I went through any way.

How did you do the axles did you get them changed to 4 stud or are they still 5. If their 4 would like to know how it was done because the axle flanges have 3 large holes in them and I can't get 4x100 pattern on the flange because one stud will end up in one of the larger holes plus on the other side of the flange the shaft tappers out to the flange and there is a machined lip and the stud will be half on it which is'nt good. But any way I guess one of the holes could be welded up and the lip on the back machined back a bit further just want to know if anyone else has any ideas.

All the 5 holes were welded up then redrilled to 4x100

Yeah what about the larger holes the ones for putting a socket through to undo the axle retaining bolts one of the studs will end up in one of the holes. Theres three of them weld one up and it would work not sure if its safe though.

technically it cant be done, a stud is load bearing, and cant be mounted in a "hole" that has been welded up, no engineer will pass it (if they know its there) but thats how mine are done (gem axle converted to commo5 stud)

I'm pretty sure there are billet steel blanks that can be machined to suit their intended application. I know there commonly made for 9" diffs but if you look around you may find some available for holden diffs also.

I did'nt think a stud in a weld would be good either I thought of pressing a dowle into the hole and welding it so it can't move my other idea is to see if there are any other axles that fit the borgwarner housing with a differant flange :? Anyhow I think I'll be sending them away to a place called diffs r us they will shorten redrill ect all in one for me make's sure its all perfect seen as their specialists.

Yes and no. The australian Piazza centre or diff does not fit. An early Piazza diff [torque tube type, not availible here] fits in a Diesel diff.

yes R31 australian skyline use a borg warner diff with a 4 stud pattern easy to just drill 4 new holes in a 100mm pattern and pop the old studs out!
