hi all

i was talking to a bit of a nissan guru the other day about what gearbox to run in my R32 when i do the conversion. he said that rb20 turbo and rb30 NA gearboxes are exactly the same apart from the ribbing on the box housings. so they are week. he then said that i should get a R33 box as they are the strongest. he said that the r33, rb30 turbo box and the navara V6 manual gear boxes are exactly the same.

has anyone ever tryed to fit a manual gearbox out of a navara? or have they ever seen one and been able to say that they are the same box?

i know this is a big ask but any help would be grately apreciated

2wd navara's run the big 5spd aka vl turbo, gtst box when behind vg30de's

I believe it's the VG30E (ie SOHC) in the Navara, and yes the 2WD version uses a gearbox which is similar in size and strength to the R33/VL turbo types BUT the bell-housing bolt pattern is very different and it won't bolt up to an RB block without an adaptor plate (or changing the bellhousing - if possible).

thanks for the HELPFULL posts.

the 2WD version behind the VG30E is the one i ment sorry i didnt expand my question.

so same box on the inside but wont bolt up to an RB without some work

would the gears drop into a VL turbo or R33 gearbox casing?

the reason i am asking is because a mate of mine needs a V6 navara engine and i need a box so we are maybe going to get the engine and box together.

thanks

The gearbox really wont be a cost viable option i dont think... if you get it for $100, then maybe. But even then...

By the time you dick around as SteveL said, with either the bellhousing... i know around the $1500 mark as a mate had a R33-t box modified to suit a 240z... or adapter plate, less $$$ but still a mission

The R33 box could be had for less of an overall cost, and also less time spent working it all out.

As for the internals interchangeable... not sure

does anyone know what ratios the navara box runs?? i figure they would be different to skyline since its an NA V6 3L work truck, not a straight6 2.5L turbo sports car.

Pretty similar probably, the diff is usually where utilities get their short gearing from.

We took the internals of a Navara box and used them in a VL Turbo gearbox once. Can't find the MX7 anywhere, ridiculously rare. For this reason, converting to a VL turbo box is a pretty silly idea.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
