question for '96 xantia td owners
what revs are you doing at 70mph???
I need to know coz I'm chucking the engine in my vw campervan and need to rebuild my gearbox with ratios to match the engine rpm

The gearing for a 1.9TD engine is usually about 25-28 mph/1000rpm depending on the vehicle it's installed in.
I would be aiming for the lower of those figures, considering the brick-esque aerodynamics of the vehicle you're putting it in. If the gearing is too high, top gear will be fairly useless.

This is not a signature.
Peter thats way too long legged a gear ratio.
That would equal approx (2500/70)*50 = 1786rpm at 50mph.
My BX TD is doing 2800rpm at 70mph
- or some 2000 at 50mph.
Thats the longest legs I've ever had on any car I've owned, including the CX.
If this engine have to push a VW camper, it must have shorter legs to be both driveable and economical

I was only approximating it against the XM, which is a bigger engine but in a heavier car, that does 2,400 rpm at 70 mph, or at least, that's what it says its doing! and my td CX was about the same. Thats why I said, 'look in diesel car'.

I agree with Anders on this one.
My two have slightly different gearing because the wheels aren't the same size, one has 185/65/14s where as the other has 185/65/15s.
2000rpm is about 50mph on the smaller wheeled car and a bit higher (approx 53 mph ??) on the other one. That gives 2800 rpm for the older car and something like 2650 for the other.
You may find that gearing a bit high in a VW Camper because its not exactly aerodynamic.
The XUD TD produces quite a lot of torque (more than a 2.0 litre petrol) so your gearbox may not last a long time. I remember when they did a similar conversion (albeit to a Beetle) on the Scrappy Rally that the gearbox didn't last the length of the program.

cheers for that, thought it would be around the 3000 mark.
the scrappy races beetle is a standing joke in the vw scene as there are a lot of 200bhp beetles/campers running around with standard gearboxes.
the bottom end of the gearbox should be fine as the xantia is heavier than my camper anyway, it was just motorway speeds that would be the problem. Aiming for 65mph @ 3000 in top so should be ok when I encounter any hills

Are you using the Xantia gearbox? If so, you'll be absolutely fine with the torque. If not, you may not be.busbuddy wrote:cheers for that, thought it would be around the 3000 mark.

The Scrappy Races Beetle used the standard VW gearbox which usually has an engine with about half the torque of the TD, they'd tuned the TD a bit too (for extra power, torque and smoke!). Its the torque that kills a gearbox, not the power.
I have heard of Porsche engines being put into VWs but I'd assume you'd want to use a Porche gearbox so that it doesn't get broken (or at least an uprated VW box).
no not using xantia box as the engine has to be spun round 'in-line' to fit in the back
turbo subaru engines are the popular choice for vw's at the moment and most with stock boxes so torque ain't the problem.
porsche engined vw's are still quite rare due to price of engines, but they are starting to get popular mainly because of the early vw camper that took part in last years 'gumball 3000' running a porsche gt3 engine.

So what went wrong with the Scrappy Races box? Did they forget to put oil in it or was it them wimmen driving itbusbuddy wrote:no not using xantia box as the engine has to be spun round 'in-line' to fit in the back

Jamie Oliver has a Porsche engined one, the Stig drove him around the top gear test track in it...porsche engined vw's are still quite rare due to price of engines, but they are starting to get popular mainly because of the early vw camper that took part in last years 'gumball 3000' running a porsche gt3 engine.
