has anyone used a different gear box in their Kombi ? as i notice even the people that do convserions use the standard kombi boxes.. im interested in 5th gear for eceonomy purposes

Nick

This has been discussed a few times in the past. To summarise: Don't bother! With an aircooled engine, slowing the revs reduces the cooling. With a water-cooled engine, it is easier to put bigger tyres on to change the ratios (though it does also change the speed on the speedo!)

To improve economy the traditional methods of reducing the junk you carry around and reducing your speed are the easiest methods. The next easiest is to keep the kombi in tune!

Tyre size on the rear to lower cruising revs wont affect your speedo, unless you change the front ones as well, as the speedo is driven off the front wheel

well im considering a V8, but regarless i was mentioning this topic in the hopes someone had insstalled a 5 speed gearbox

perhaps germanlook.com forums would help you, if/when they come back online that is...

if its in a splitty then change it to IRS and get rid of the reduction hubs

If its in a Bay then you have what you have due to the weight of the vehicle reduce weight or install a more powerfull ecnomical engine

the cost of the 5 speed will be too expensive vs the engine change or reduction gearbox removal

what are the point of the reduction hubs ? wouldnt you want the bus to go faster ?

yes people have used different gearboxes in their kombis...porsche for example...but don't think this will be economcical...if you want economy keep the standard box and install a subaru EJ22...then you can put some taller tyres on and get 30mpg at 120km/hr

im lookig into a 1UZ-FE engine, trying to get around 10L/100km, but then again im hopig to run it on straight gas

heheh...talk to mini-man about 1UZ-FE's and gearboxes and being economical...good luck

well they couldnt be much worse than kombi engines..

hee hee,,, well,,, just my type of topic :-) :-) :-)

666,,, we meet again my friend :-) Go for it i say,,,, but yeah G50 porsche with "LOTS" of mods to make it all fit, cutting torsion tubeout, fabricating brackets to accept the gearbox mounts bot front & top/bottom supports,,, making up toweres to accept the fittment of coil over shocks &/or airbags , gearshift changes, adaptor plate, flywheel & clutch assy, engine crossmember, efi fuel tank etc etc etc

Not a job for the faint hearted nor is it a job for anyone with little money or time,,, talk with Aaron (black Kombi 20B turbo rotary powered Kombi for that , he`s still spitting the porsche boxes & diffs :-)

I went for the full Albins after market gear kit in my late 2 litre thick rib kombi box with very very over driven top gear,,, also recently fitted Peloquin limited slip diff too,,, lots of bucks but seems to be holding up ok now days (cross fingers,,, ouching my woody, preying i havn`t just hexed myself) :-) :-) :-)

early splitty kombi boxes ran reduction boxes on the end of their axles because they were effectively std beetle boxes with the diff turned around & so added the reduction boxes to increase the torque to carry the extra weight that kombis inherantly continue to be abused with,,, just forget about the early boxes man, they will just burn holes in your pocket & drive you insane,,, trust me :-)

If you decide to go Porsche box, then be ready for all the fittment mods & costs & also you`ll most probably need to sort all your gear ratios out anyways,,,, it`s all just very expensive,,, There`s also the "Renault" gearbox route ,,, they`re a very tough box & less work/cost to fit,,, However Albins gears in a late kombi case can hold up to around 400hp-ish & don`t cost an arm & a leg,,, maybe just an arm "Or" a leg :-) but well worth it i reckon.

So Matt ....are you 'armless or legless now???

hee hee ,,, Matty , you know i didn`t trade my arms or legs for the Albins box,,, just put them in hock at Cash Converters for a while till i can pay them off & get them back :-)

But yeah i`m usually legless on most friday nights :-) When you commin over for drinkies & party & stay the night & we go wheelstanding & doin donuts in the kombi at 3 in the moring???

Sounds like lotsa fun, you know I got the beach real close.....

I`ll be ringing you soon for a get-together,,, we will be getting quite "leg-less" & i`ll be staying the nite,,, i`ll bring the kombi so we can do wheel stands & burnouts at 3 in the moring , OK?

:-)

you do have a spare kombi box to fit in the morning tho hey?????

Ahhhhh... toyota engines... mmmm what a feeling!

hehhe, i luv stirring

I'm pretty sure its like about 250-300 bucks for some different 3-4 gears for a 5rib kombi box. My ej22 kombi drives alright in the first 2gears but it would be better with a little bit taller 3 n 4th. Thats what I will be doing
