G series Gearbox - Page 3

bourbon · 07-11-2008, 11:58 PM

have a search...its been talked about heaps...even part numbers youll need to order the stuff frrom mazda...

mussing · 08-11-2008, 12:22 AM

There's a g-series gearbox on fl.com for $500 in brisbane here. Shouldn't cost that much to courier it down...

rodhog · 08-11-2008, 01:19 AM

you can find 2.2L 5 speeds from gD models - better off with Gd1022 chassis- that's 90 model onward or 89 novemeber build onward
they are normall quite cheap $200 upward.

5th gear swap . I've never doen it but I can tell it's PISS ANT EASY.

you only really need a rattle gun for the two main nuts holding the onto the shafts and you can do it in the car too.

As said its been done before.

Rupewrecht · 08-11-2008, 12:50 PM

The 626 gears can be ordered from Mazda, and are about 300ish for both. The part numbers are floating around here somewhere.

As i said, it can be done in the car if you're really keen, but you'll need an impact wrench to remove the 32mm and 36m nuts. 5th is easy as it's outside the main casing and just covered by the black pressed cover on the end of the box.

Apparently there was a diesel 323 in Europe that had an even taller 5th ratio, but i've never been able to find the part numbers or get more info.

rodhog · 08-11-2008, 10:41 PM

It's not worth trying Rupe as I know sort of in my mind have and idea and it would be so tall a Bp would not pull it. You would be working the car too hard so economy would be gone.
626 has a .680 I think that's the one.
i can only really think of a few mazda motors made to pull that gear from 2000rpm and excellerate

final but for it was 4.105

might not be as bad with the 4.388 diff but

Rupewrecht · 08-11-2008, 11:06 PM

I think the torque of a BP-T would shatter it if it was much lower, anyway. They're too small a gear, and of course there's no way you'd want a straight cut 5th if you drive any distance. Even i'm not that hardcore

But yeah, the lower ratio i was talking about was a .68 from a euro BG chassis, apparently. Didn't know it was the same as one of the 626 5ths.

I'm more interested in it as with the solid engine mounts i get a more noticeable vibration at around 100-110, and the 626 5th will hopefully just drop it that few hundred rpms to be a little nicer.

rodhog · 09-11-2008, 04:21 AM

B series and like most 323's get 2nd hand hand me down Mazda G series car parts. IT's why for a bit of time it was all G series box's
Then mazda went skimp.

BP-T - torque not enough.
I've been in heaps and all big boost to make that torque
Can't compare to a F2 -or F2T especially - At the moment many a owner is needing 5th gear because they have worn the dog teeth on slector hub ring or gear itself even.

They are small but it's a sore point but you don't need stragiht cut just some newer desgined gears , still helical cut won't be that noisey.

But yeah vibration all rotating parts have a two zones to get through in terms of blalnce in vibration - regardless of how perfect it is.

Most occur from 2800rpm to 3200rpm - 3000rpm said to be the main area.
It's why alot of cars gearbox's you will note have ratios set just below this. for 110km/h

But also when it gets upto 30,000rpm it's another threashold the rotating shaft etc has to break through.
It's all to do with harmoics and balancing.
I keep getting reminded about Gas turbines etc.
Dam Work.

stupid box is a pain to take out? anyone got pics on this and where ALL th bolts are that hold it on?

OZY-323 · 02-12-2008, 11:02 AM

ok, its in all wired up, just need HELP with one thing??? the water temp wire where does it go? i cant remember can someone tell me or show me please? thats the only issue other than that the car is fully functional! yay!

chicaboo · 02-12-2008, 11:18 AM

If it's like a BJ, it's on the back of the engine (left hand side of car) about 12" infront of the throttle body on a copper coolant pipe, about 6" down from the top of the valve cover.

Gav.

Dogo · 02-12-2008, 11:57 AM

should go to the temp sensor on the thermostat housing.

just below and to the side of the distributor. Follow the upper coolant hose from the radiator to the engine

OZY-323 · 02-12-2008, 12:32 PM

hmmmm, the temp sensor is in, its this one that is playing up?

does it plug into this?

cause evrytime i do the temp goes right up? i take it off and it goes all the way down?

bourbon · 02-12-2008, 12:50 PM

thats not the O2 sensor wire is it?

the mechanics who did mine in nsw screwed mine up and put the water temp into the O2 sensor and not pluged in the water temp :@ :@ :@

OZY-323 · 02-12-2008, 01:11 PM

i'm not sure theres two that are simmilar how do you tell which is which?

bourbon · 02-12-2008, 01:40 PM

just swap em over and see what it does then...

Cosmo Dude · 02-12-2008, 01:45 PM

The gold thing is an earth point, the black plug behind it looks like the ECU temp sensor. There should be another in that area from memory.

OZY-323 · 02-12-2008, 02:00 PM

tried swapping them, but i still dont know where to stick the other one? i cant find another earthpoint?

Dogo · 02-12-2008, 03:12 PM

looks like an earth to me. Connect it to that metal tab

OZY-323 · 02-12-2008, 06:01 PM

ok coolies, connected the yellow wire to the earth tab, and as for the water temp sensor? well it was snapped so thats why i couldnt find the tab, quick visit to the wreckers $5 later new sensor with tab and i can finally see how hot my car gets, thanks the massive help on the sight with the new gearbox setup and advice guys...
