No idea, they don't exactly share everything they do with good reason. But it was a 33 box haha. who knows whether it had an aftermarket gearset or what clutch... all I know is it crossed the line without munching the box haha.

R33 boxes can handle some descent power

Anyone have any info on the r33 auto conversion.. I've got calais with rb25 conversion not running yet.. Car use to be 5ltr does anyone know what speedo drive to use In the auto?? And will the standard 6cyl shifter fit on the r33 auto box.. the car still has v8 shifter which selector is on opposite side to the box

Guys, not sure if it was ever mentioned in here but the reason the 10" flywheels doesn't fit in some R33 box's is that there are two size's. They are known as a big or small R33/34 box. Get the "big" housing box and you won't have any issues with the 10" VLT flywheel.

No ****... the small one is the non turbo skyline box which is pretty much the same as a VL non turbo MF5 box

Hey all. I have purchased a r34 gearbox to put into my vl which currently is running a mf5 manual gearbox. Question is, to swap the r34 gearbox from pull to push, can I use the existing push setup from my mf5 ? What have other people done to get around this ??

who has fitted 1 piece tail shafts when doing this conversion. what length was the shaft and where did you take the measurements from.

so no body has fitted a 1 piece tailshaft with a R33 or R34 box ?

call hardy spicer

why do you want a 1 piece? If your cars low itll rub/hit on the floor

its not that low. it may touch with full compression of the suspension but not likely

Hi guys I'm doing a auto NA to Manual R33 conversion next week. I believe I have everything but I have a few questions. 1, can I still use my auto speedo cable, or do I need a mx7 one? 2, do I use a mx7 hydraulic clutch line (from clutch master to slave cylinder) Or do I have to get something custom made up? Is it long enough? Does it fit on the r33 slave cylinder? 3, if using the auto or mx7 speedo cable, do I need the 90 degree adaptor on the speedo pinion? 4, lastly, do I need the manual floor plate? Any info will be a big help. Thanks

Bumping this thread. I have an R33 box, and 4.11 diff gears. I need a MX7 speedo drive and what else???

Hi all Is this the correct part number for purchasing an R33 5 speed manual gearbox to install in my VL? ECR33 RB25DET gear box part #32010-21U60 Anything else I need to confirm before I part with my funds? Regards, HDTGM1
