Outer Limits 4x4 Board

Is there anyone out there who has done this conversion , or know 's how close they would be to lining up.also what difference in gearing .Any view's on this conversion would be appreciated.Is there any more on this subject in previous posts.

One question...why would you do that?

i am after a 5speed gear box that doesn't have the shifter overhanging the output shaft , this is the only gearbox that i have seen so far that is suitable.

Indeed, why is a gemini 5 speed better than a suzuki 5 speed?

I'm not aware of any real weakness in the suzuki box, and they are available 2nd hand.

Ok. Never heard of it being done. What's the application?

I wonder how the two gearboxes compare strength wise ?

sorry elado, but really, who cares? Not many people have actually broken sierra gearboxes. Sure, they wear a bit, but the newest sierra gearbox is about '98. What's the newest gemini box? 84?

By the time you resolved adapter plate, starter, overall length, output shaft length, mount, tunnel clearance, clutch actuation, flywheel, starter motor location & engagement, the Gemini box couldn't possibly be good enough to warrant the work.

Gemini's had relatively little more power and no more weight than a sierra stock. They are unlikely to have a lower 1st gear (sierra - 3.65:1)

I really can't see an advantage. I fyou have a shed full of gemini boxes and a broken sierra box, sell the gem boxes on Ebay and buy a god used sierra box.

Steve.

yeh i see your point steve , The reason is to get rid of the overhang at the rear of the box.I have seen late model jeep boxes with less overhang but they would be too expensive to buy.

what the hell are u tryin to do????????, if ur that keen on a jeep box go by a jeep.

i'm keen on a gemini 5speed gearbox not the jeep

What everyone is asking is WHY DO YOU WANT TO REMOVE THE SHIFTER OVERHANG. If you can give us more infomation we may be able to help you more.

I am trying to have 5 speed gearbox & still be able too put volvo 4speed box behind it ,Like they have done over in sweden. That way i'l be getting all the highway gears & heaps of lower gears down to about 110to1.

drugs are bad maybe you should take some time to think about this process a little longer.

i'l just do it it will be cool

I got the info from this site http://www.suzuki-samurai.nl/volvo/volvo-eng.html

I thought that's what you might be trying to do (the volvo thing).

Yes it would be possible, and depending on how you speak to it might be cool. But by the time you stuff around adapting the gemini box to the G13 as well as the volvo box to the gemi box, it will be cheaper and most definitly easier to just to throw a set of gears in the standard transfer case.

I am trying to think of some positives for doing what you propose, but I can't. If you want to do it just to be different, hey knock yourself out.

Thats a 1.0 litre zook, which have a much shorter 4 speed gearbox than the 1.3's 5 speed is. Maybe you need an old 1.o litre zook, not a Maruti tho, as they are longer boxes. Or a Lwb for extra room.

A dude in our club had a swb 1.0litre zook with a Gemini deisel and box fitted, and there was not a lot of room left to connect it to the transfer box, without moving the t-case.

I believe you'd be better off to use the entire motor and box from any car with a short enuff box for ya need, less hassle.

Yeh , you have to mix & match between 410 & a carryvan gearbox.

lower tranny gears, lower highway speed,i want too keep highway speed as is with a fifth gear overdrive & have heaps of lower as well

Think about that. If you fit say Calmini 5.14 gears, you get much lower low range at around 127%, and about 18% high range reduction. BUT why would you fit the gears in the first place - to regain crawl with larger tyres. So, the high range reduction allows you keep resonable performance with these larger tyres on the blacktop.
Where is the issue with having your high range corrected for your larger tyres to regain normal (for a zook) road revs vs vehicle speed.

What size tyres 7 what diff ratios r u running?

standard 85 nt lwb rocky sevens

Calmini 5.14 gears are too many $$$$$$

good luck tryin to find that volvo box i was goin to do this a while ago and could not find a box in wa. anyhow with the cost involved getting the box and volvo plus adaptors cross members etc etc it will be cheaper and easier to do the calminis.

i dont think you will have enough room. looks like he has custom drive shafts too.

and why the hell does the dude on the site have 1 (or 2) spark plugs in his exhaust?

do you want a flame thrower as well?

i already have a gearbox 40 odd thousand on the clock, out of a 62 volvo amazon .It was written off in a smash. You can still get the parts for them as well. A bit of cutting a bit of welding , some

A Gemini box is close on unburstable, 1.6, 1.8 all the way up to the 2.6 litre rodeo motor is the same internals. and there are plenty out there with serious power being put through them and still living a long happy life.

Now the logistics of the install may be a bit more difficult with quite a few custom parts .. once it's done and you get all the angels etc right .. it should be pretty good ..

Remember to beef up all the mounts etc .. and give us progress reports

cheers thats what i like to hear,the volvo is an extremely strong box as well.

5th gear in the gemini box is not real strong. 5th gear is an add on to the 4speed box from the 70's.
We use to break a circlip. But it was behind a turbo motor. So prob' wont be cause you any trouble.
Good luck, hope it works out for you.

Yeh thanks me too.
