Why not recon the trans with a 7/29 cw/p set for a 10% gearing increase Nev? My 2.6 does 75 at 3800 and sounds sweet, returned about 26 mpg using 98 RON on the Autobahns and Autoroutes even on the standard 7/32 cw/p. But that was with fresh 205/65/15C tyres so probably a lot less rolling resistance than with wider tyres?
Have I missed anything?

Today I finished the gear box front mount and the gear linkage.
I can now select all gears from the cab via a std 5 speed gear stick.

I am looking at getting the mount and gear linkage parts laser cut. Once this is done I will have a better idea on cost.

Thanks all for your interest.

Tim.

That's really nice. I'm also very interrested about swapping passat gearbox to my van.
They're easy to get and ratios are so much better. I think it's way cheaper than to buy 5 speed T3 gearbox, then buy new diff, bearings and maybe longer 5th gear. Then get someone to fit them into your gearbox
I'm running aaz with 1.6d gearbox and my top speed is 100kmh (62mph) and the engine just doesn't take any more revs.

I think the only problem is that my van is so low that I may have to cut the frame a bit with passat/audi gearbox to fit the drive shafts.

How much higher the axles really are with this mod?

Almost there.

A few small items to sort out before the engine goes in for the last time.

I guess that it will be more accurate for me to measure down from the boot floor to give you a measurement. As not all vans will be the same height from the ground.

I need to get the engine and gearbox back into the bus before I can do this.

You may need to check that the starter ring gear is fitted on the engine block side of the fly wheel and not on the clutch cover side.

Best option is to use the Passat clutch and flywheel that belong with this gear box.

The gear shift is untested on the road so far, so time will tell.

Shift pattern

1 3 5
2 4 R

as per the Audi A4 gear box.

Tim - An interesting project as many have already said!  I don't want to pour cold "oil" on your ideas but I was wondering when you "invert" the gearbox, how do you ensure the oil flow around the gears is maintained as it is designed to get the oil to the right places when the gearbox is in the normal position?

The practice of running the gear box upside down is not my idea and it has been done before without gearbox issues.

As all gears are splash fed from the shafts as they rotate in a bath of oil, there is no reason that the oil will not be able to supply lubrication to all areas in need.

OK Tim - I know some cars use positive pumped lubrication but I bow to your experience with these gearboxes. Star   However isn't there a breather that needs to be relocated as this is usually at the top of the gearbox?

PS - not trying to be a know all here or catch you out! LOL I have worked on gearbox design so just wanted to check a few things to make sure I understand how this works (turning a gearbox upside down is not the usual thing done in the automotive world!!

Original Quattro boxes were OE ones fitted upside down.

VW beetle boxes have been ran upside down on race cars for years.

You are right there is a breather which is now at the bottom of the box and a new one is added to the new top of the box.

Here's a few pic's of my box fitted last year

The black rubber hose you see on the box was the breather but is now blocked off









the pipe you see in this below picture is the breather   It use to be the drain bung but is now on the top
