I've got a 2 way diff and I'd want the backlash set right so I'd have to get my diff man to set it up but I'm trying to find out which ratio is going to be best for drift with my new engine or if I should just leave it how it is.

Thanks guys

stock gtst is 4.3, which i have and ive got no probs with holding 3rd or 4th with that, i i had even more torque again (like what you have planned) i would change my diff to a 4.1

3.9 isnt really needed, bugger all difference between a 4.1 and a 3.9 anyway and 3.9's are a lot harder to come by.

  • 3 weeks later...

Conversion was successful today, took many hours a bit of swearing, welding, tapping, grunting. Most annoying part was that the rear section of my tailshaft was 17mm too short!! wtf?! will be taking that back to be rectified during the week.

280kmh dash is sweet and my guesstimations for 3.9 diff + 17T Navara cog were correct, speedo reads high by 10kmh :(

Nope, I'll try to remember to take some next time it's on the hoist.

Basically got some flatbar, cut 2 pieces, marked the holes, drilled them, bolted it up to the car with the flatbar in between, tac'd it, took it off and welded it.

wow complicated. :/

I slide the gearbox rubber mount towards the front of the car so that the middle hole in the std xmember lined up with the rear chassis holes. Then simply drill new holes in the gearbox so you can bolt the gearbox to the rubber mount.

I then bought a $2 piece of 4mm plate, drilled 3 holes, bolted the front chassis hole up to the plate directly then the xmember's middle hole bolts through the bar in to the chassis. The xmembers rear hole requires a nut with a little locktight.

Slap a little sound deadening spray crap so it matches the rest of the floor pan and its extremely difficult to pick.

I'll grab some pics soon.

Hey, i posted a question last week about my geabox getting stuck in reverse. The cause of it was that the speedo sender shaft actually snapped and left the nylon gear (and half the shaft) in the gearbox.

Ive got an R33 box in an R32 and have done the Navara sender and standard r33 gear swap.

My question is: How do i ensure that this doesnt happen again? When i installed the navara sender originally, i didnt notice that the shaft was off centre. Has this got something to do with it. Do i have to rotate the sender in the gearbox to a particular position?

I ordered the navara sender for $50 and the R33 nylon gear for $60 from Hornsby Nissan today.

Thanks,

Shaun.

That sounds more complicated than my way :) we had a 32gtst w/26 in the shop so just copied that setup but with thicker flat

When you put the nivara drive in did you rotate it 180 degree's and re-slot it?

Nope, my impression was that was for 23T (bigger gear) so it doesn't push as hard against the pinion. My mechanic has been running a standard 17T Navara sender in his 25 box for years with no problems.

Edit: I'm more worried about the funky bends in the brand new speedo cable :/

No i didnt. Why do you do this? Is it so that the larger gear doesnt push as hard on the gear in the box?

I can only assume that the shaft snapped because there was too much lateral force on it. Or it was wabbling around in there.

I suppose another alternative is to just use the Navara gear and have the speedo recalibrated (or live with it).

Thanks,

Shaun.

Mate, so your speedo doesn't work? that explains the steering going heavy after a few mins.

No, No, it only just stopped working. The sender must have only just snapped. The speedo worked ok but i still had no power steering.

Shaun.

It's just like setting up the spur gear on your r/c car :thumbsup:

^^^I dont understand what that means at all!

Anyway, i did the mod last night and put the sender with the new gear into the box in the new position (180 degrees rotated). When i turn the main shaft in the gearbox, the speedo sender rotates, so i can only assume it worked ok. Fingers crossed. The tutorial from Cubes was soooo handy; thanks mate. I didnt bother about using a circlip on the end of the shaft though. It was an extremely tight tolerance fit, so i dont think it will work its way off. What do you guys reckon?

Shaun.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
