I realise this thread is ....

Why didn't you put the 6 speed gearbox from the 120bhp version?

Because the only ones I could find for sale were around the £500 mark, and I still didn't know for sure whether I'd need to change driveshafts or clutch/flywheel or whatever, so wasn't willing to spend that amount with the possibility of having to spend more. Doing it this way cost me £250 all in with new clutch kit, new box oil and new driveshaft mid-bearing

Man that's epic!! I can't say thank you enough. I can pay homage to you courageous move only by doing it for myself.
Honor and respect to you for the ages ahead.

How about the clutch? is it the same of your 20dp33?

Yep same clutch, box slipped straight onto splines. Same driveshafts everything. A fairly easy swap to do for anyone good with their spanners. I say easy, there's one or two bolts that are a pig to get to, and you probably need a mate to help lift/align box back on but apart from that..

We have swapped our 5speed 1.6 B9 for a 6 speed 1.5 K9. The K9 fuel consumption is worse and apart from being a litte quieter I can't tell any difference in driving.

With the k9 gearbox you have worse fuel consumption?
How much engine rpm at 130km/h ?

Beside gearbox did you need anything else? And do you think it's worth the swap or not?

How much better is it on fuel ?

I realise this thread is 2 year old but for anyone else landing here from a Google search like myself and SJR this may be of some interest. I couldn't find anything definitive online whether there was a 6 speed box that bolted straight on without having to change shafts, clutch/flywheel etc. But I was also not happy sitting at 2500 revs doing 70mph it doesn't seem very efficient at all. The box on my van was a 20dp33 which I think is fitted to most of partner/Berlingo b9s. Since I couldn't find any info about a 6 speed conversion I decided to look for a 5 speed with a longer 5th. Again managed to come up with no info anywhere regarding that either. So I decided to take a wild stab in dark. Just searched 1.6hdi box on eBay, and tried to imagine what cars might be more for cruising. Spotted a 60k box for a c4 cactus (code 20et15) for only £150 and thought f it n hit buy. It looked identical to mine so I knew it'd bolt up to the engine fine, just needed to swap selector on top from my old box. It arrived day after n I fitted it last weekend with a new clutch etc. I'm pleased to confirm 4th n 5th gears are both slightly longer n now the van sits at about 1900revs for 70mph now as apposed to the 2500revs with the old box. Very happy with the results n now I don't find myself automatically looking for 6th hearing the engine revving on motorway

On the State Road it went from 13 km/l to 16 km/l

That's a major improvement!! Going from roughly 37mpg to 45mpg. My van needs a clutch soon so I think I'll go for this swap. Thanks a million!

Will the 120bhp gearbox fit then?

I am interested to know if it was a straight swap without the need for additional modifications. thank you.
