Re: 6-Speed Gearbox
Hey Doggy great to hear you managed the conversion !
I managed to add a 20MB04 'box to my collection of mods to finish rebuilding my car...
Just have to find the time to finish it off ! Been off the road too long now ;(
...altho looking at ur pics of the speedo drive gear transfer ... i'm thinking I Could also do with popping an LSD in there while i have the diff casing off, as it always had 1 wheel spinning if steering at all in in 1st or 2nd ...
Ok now I need to find more cash

Re: 6-Speed Gearbox
So I take it that putting a 6 speed box into a D8 is all but impossible?
I would definitely benefit from one as I'm doing about 800 miles per week, 500 on motorways

You will need to convert to a hydraulic clutch.
You'll need the gearbox from the 407/C5 and clutch, flywheel and drive shafts from the 2.2 HDi.
You'll also have to work out the RPM signal but I can't see that being a big issue!

you could look at the bolt pattern for the bellhouseing to gear housing then you would not need the clutch and stuff, just the gasket if they mach up. but thats getting abit more complicated

The main issue is the 1.9TD has a cable clutch where as the rest of the 406 range don't!

Re: 6-Speed Gearbox
Don't want to rain on your parade, but I don't think a standard 2.2 would pull 6th comfortably - even with 235 lb/ft, so I really can't see a 1.9 hacking it.

Re: 6-Speed Gearbox
Right so no point doing it until I need to change the clutch.
Sounds fairly complicated altogether!
gearbox off a 2L HDi 407/C5 and clutch/flywheel/driveshaft off a 406 2.2 hdi? or the 407/C5 again?
plus labour as there's no way in hell I'll be doing it myself. Can do small jobs myself but this is way out my league.
Doggy I would only be using it on motorways, 75mph+ where the engine is doing plus of 3k revs in 5th I reckon the 1.9 could cut it as long as I go fast and I've no problem doing that Could always screw it a bit if she's struggling anyway.

Re: 6-Speed Gearbox
306 HDi gearbox would bring it down by about 500rpm and still has a cable clutch!

Re: 6-Speed Gearbox
I was thinking along those lines too.Bailes1992 wrote:306 HDi gearbox would bring it down by about 500rpm and still has a cable clutch!
IIRC my bro's 1.9TD was about 28 mph/1000 in 5th, (as was my '99 Xsara HDi 90), a 110 HDi 406 is about 31 mph/1000, BUT it's probably got similar ratios and a higher final drive.
Having driven a few 405 TD estates, I remember being impressed how well the 1.9 lugs the bigger 406 estate, but I strongly ssupect that means Pug have got it just right as standard, tinker at your peril.
Be careful with 407 6-speed 'boxes. 407's have 17" wheels, hence lower gearing to compensate......

Re: 6-Speed Gearbox
anyone know if a 20MB02 6spd gearbox will fit a 406 110bhp there seems to be loads of them around fairly cheap.

Re: 6-Speed Gearbox
I assume this means it would be a much easier swap than having to put in a hydraulic clutch too?Bailes1992 wrote:306 HDi gearbox would bring it down by about 500rpm and still has a cable clutch!
but even then I'd still have to change flywheel and driveshaft right? Seems a lot of effort for 500rpm less!

Also, jasper5 reckons the 16V 2.0 HDi in the 407 has a bigger DMF and clutch, hence a bigger bellhousing.

You'd have to fit the clutch release fork from the 1.9TD onto the HDis gearbox.
Should be a straight swap then!

Re: 6-Speed Gearbox
There is no guarantee of better fuel consumption with a higher gearing. It may work out that you need to use a little more throttle to pull it 'over-geared' which could bring your mpg down. I have had friends change their overall gearing just by fitting larger diameter tyres, and fallen foul of this.
FWIW, my Phase 1 306 TD sedan was 26mph per 1000rpm in 5th. Running on 185/65 x 14 I could get 65mpg at motorway speeds. Downside was that the tyres were of the 'semi-slick' type, and hopeless at emergency stops in the wet. (Fronts locked up too easily.)
