I used the uni joint (flexible 3/8 drive) up until half way along the gearbox and then used another straight extension with he correct size on the end. It means you can use your ratchet in an open area down the back of the gearbox, hope this helps because they can be a bitch otherwise.

From what I've read, the turbo driveshafts are the correct length, but mine certainly wasn't. Converted from a manual RB30 to a RB25DET with the big box. Maybe if your only putting the 25 box on the 30 the spacing is different??

Maybe the 25 block is a tad shorter than the 30? or it sits slightly more forward on the engine mounts than the 30 does? or a mix of both even. does your shifter sit quite close to the hanbrake in 2nd,4th and reverse, as mentioned near the beginning of this thread? or does it have a bigger gap?

http://www.driftshop.com.au/interior.htm Peoples thoughts on those shifters?

The knobs all look wanky, but the quick shift kit looks ok.

Which one? I couldn't decide between the top and the second, I thought the second had the goods but I doubt it's still on special. And I'll most definitely be getting a thread on it so I can put the existing knob on. Everyone needs a good knob.

the spacer on the cross member is 12mm and keeps the drive shaft central. I used a rubber flex line from a bluebird to adapt the vl clutch line to the r33 slave. cheers

righto i got some questions i am just about to convert to rb25 gearbox. currently i am running a rb20det manual gearbox. 1. what speedo drive do i need to buy and where from? part no. etc so my original speedo cable that was in the rb20 manual gearbox will work in the r33 gearbox OR do i need the MX7 speedo cable aswell as a new speedo drive??? 2. the rubber flex line off the slave for the r33 box has been cut, what can i do. does the clutch line screw straight into the slave?

It may screw straight in, but there have been reports of this not being possible. Unfortunately you won't know until you try. If you need the car day to day, I'd suggest you find out before you pull it to bits. I'm not 100% on what the RB20DET box runs, but if you're using a VL cable then your CABLE should be fine. But for the speedo sender unit, you need an MX7 one (VLT), or a Nissan Navara speedo sender unit.

Not sure about getting a new speedo cable from Holden. Give them a call.

Give them a call. are you sure the navara speedo unit is the right one, i went down to nissan yesty and had a look at it. the gears are different sizes and apparently they dont seat in the right way, you need to modify them so they sit on the right angle etc. as the gear is off centre. is this true? or is it a matter of just unbolt the electric unit and bolt the new navara one in, the gear on the navara one is alot smaller etc. i went down to nissan yesty to look at the navara speedo drive, and it looks fairly different, the gears are different size etc, i dont know wheather you have to change the gears over?? f and another guy in there was telling me you have to modify the navara drive by cutting a slot in it so you can seat it into the box on the right angle, as the gear is off centre. is this a lie or?? im in two minds now, i dont know weather to get the navara speedo unit or not. can someone shed some light on it, is it a matter of just bolting the navara unit in??? is it that simple, with no modiffications

I've never personally used the Navara unit, but there are quite a few people in this thread that have.

hi ppl this is my 1st ever post too and im going from a mf5 to an r33 and so far i have pieced together the followin bits to complete the conversion if i have left anything out please let me know *mx7 speedo drive *mx7 slip yoke *r33 slave cylinder *r33 short shifter where are the best plces to get the mx7 speedo drive in syd mind you i already have the r33 box these are just the extras i need

Welcome. You may need to get a custom clutch line made up, depending if your line suits the master/slave suits your current line or not.

Just wondering if ya can help me? I just put an r33 5 speed in my calais and have been told that i cannot fit a speedo cable from this box to the gauge because the gauge is analog and the box is electric do you know a way around this any help would be good thanks Quote: Originally Posted by 5spdvl I will give my opinion on your comments tomorrow madrx3boy when I have sobered up. Ok. 1) Your clutch choice is inconsequential to your conversion, as long as it's an RB clutch (9.5" N/A Vl or any Skyline would be preferable over a 10" VLT unit). What clutch you choose depends entirely on your power and application. Speak to a clutch expert and see what they recommend. 2) An MF5 tailshaft will come with the centre bearing already fitted. All you need to do is change the yoke to an R33 item, available from Hardy Spicer for ~$100. 3) A VL clutch master cylinder is fine, bot for the slave cylinder you will need an R33 item, as the bolting pattern on the bellhousing differs to the VL item (two bolts on one side, as opposed to one bolt on either side). Some people have issues in getting their stock clutch lines to connect easily between the VL and R33 clutch master and slave cylinders; I will standby my ongoing recommendation to every one to take both cylinders to a clutch or brake specialist and get a custom braided hose made up that fits perfectly on both ends. Do it once, do it right. a) Auto speedo cable is fine. b) To be honest, I've no idea what the neutral switch is supposed to do exactly. My guess is there is some degree of similarity between the auto and manual body harnesses of VLs, and the manual neutral switch is supposed to trick the car into thinking it is always in neutral (allowing you to operate the starter motor); however, when converting to manual it never works like that. Either the auto selector switch needs to be rewired, or the relay behind the battery. There is information in the Auto to Manual Thread (http://www.calaisturbo.com.au/showthread.php?t=74074) about making your own loom. c) The auto crossmember will not fit. They are different. And yes, they will bolt to a different set of holes on the floor pan (you'll see them immediately when you remove the old crossmember). The rubber mounts are the same between auto and manual. d) Not sure about the clearance, but it shouldn't be an issue, with this many people putting R33 boxes into their VLs. As for spacers (where required), thick washers should do the job, just big enough to go over the bolt and create a good "footprint' for the crossmember to push against. e) That's a good question. I was provided with OG manual bellhousing bolts, but there wasn't enough. So I have a combination. It's never been an issue; while you're there, you'll see which ones will and won't fit. There is only one bolt that's an issue, and it's because there is no thread on either side (engine or bellhousing); it requires a nut.

If we're still talking about the R33 box, the part number listed above will work. Even the guy that put it in my car was skeptical but he put it in and it worked.
