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 German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
