Diff done

GT-R Diff with S13 Rear Cover

Dropped into C-Red today to check on some parts I left drying over the weekend. All looked good. While there, Roy and I quickly changed over the driveshaft flange on the GT-R diff to one from an S13 diff to match up with the S13 drive shaft (funny that). We also fitted the nice shiny rear cover (and new gasket) and the results speak for themselves.

Also put back together (after painting) the braces I got in last week - being the Do-Luck 'Style' Ladder bar brace, which ties the chassis rails together around the front section of the gearbox, and the rear lower tie rod brace, which ties the lower tie rods together where they bolt up to the somewhat thin part of the rear subframe. Look good don't they.

Over this period of pulling apart the rear end, I've slowly been gathering an assorted of nuts and bolts - all looking a little tardy, so I grabbed the box that I was collecting them in, chucked in all the other assorted nuts and bolts around the car, and dropped the box off to the Zinc Coaters. Have asked to be ready on Saturday so I can bolt the stuff together.

I’m interested in putting a Gtr diff into my s13, how much mucking around is it to make it fit? How do the half shaft lengths compare up?

Kane, unfortunately part of the conversion process was carried out while I wasn’t in the workshop. But from what I could tell, the process wasn’t that difficult. With the rear cover replaced with an S13 one, and the front flange for the drive shaft also swapped over to an S13 one, the diff itself was pretty easy. What I can’t recall was whether or not we used R33 GT-R rear hub carriers or not (I don’t think we did), for the R33 GT-R shafts to fit properly. All I know is that when it came time to put the rear end together, it all went together like it was meant to.

Ok cool I’m going to be running big power so the thicker shafts are desired. Maybe i need to drop into CRed and get some info.

Thanks Brendan
