Just finished my GTS-t RB26 sump mods

[Chris Wilson]

Short of a bit of fettling, a quick bead blasting and a thorough cleaning I have finished hacking off the front diff from an RB26 cast alloy sump with a Trust sump extension to go on my RB26 engined R33 GTS-t. I wanted a cast sump as it ties in the block and gearbox more rigidly, adds rigidity to the bottom of the block, aids oil cooling and allows known and tested commercial bafling to be used. All preferable to the admittedly lighter pressed tin RB25DET sump pan normally found in an R33 GTS-t. I also removed the front driveshaft tube and bearing housings, welding up the resultant holes with alloy plugs.
