Hi, They are actually old Range Rover wheels in a peculiar size of 6x16. It was convenient the offset was just right. They don't fit straight on sadly. I had to make hub adaptors for them.

Guys, I just looked up the Montego diesel engine. It only has a few more HP than the 6 pot lump I have now so what is the benefit? I know it is a good unit and efficient but it cant be better than the 1.9tdi. |

the main reason I mentioned the montego 2.0 TD was because it would be a good strong economical and simple, (no electronics to worry about), replacement for an old 2.0 petrol LT (a straight six won't fit in the hole without major alterations apparently).

I'm curious to know more about how you linked up the gear linkage. This is the hardest part of these engine conversions because the gearchange is via levers rather than cables.

Hi, For the V6 transplant I cut the gear lever from the Scimitar gearbox short and then trial and error bent the VW linkage to shape, bolted it to the stubby gearlever and just kept working it until I could get all 4 forward gears. It took a little while but we got there in the end, and it now works as well as it did with the VW running gear in it, or should I say, just as badly! I am now saving up for a sequential gearbox from Elite transmissions. That would give me a clutchless 6 speed manaual with a choice of ratios so I can get a really overdriven 6th. The trouble is it is £5000!! Yep that sure is a lot of wonga...

That's interesting to know... I haven't really looked at how the gear linkages work on the LT but going by what you're saying you could cut the gearstick down on any RWD gearbox and modify the original linkage to suit (with time and effort). That opens up a whole relm of possible engine/gearbox combos....

It took a lot of fiddling with the linkage in and out lots of times with a small bend at a time, but anything is possible. The main problem is that you are converting the linkage to operate from a side lever gearbox to a top lever one, so you are altering the pitch angles the linkage is designed to operate through to actually select the gears. Added to that you have the problem that the RHD VW linkage was clearly designed by a German seeking revenge for WW2!! The quality of the whole thing is pretty poor with rubber 'balls' where there should be rose joints, etc. That's why it's never any good right from new. If I don't go for the sequential box I'll re-design a new linkage from scratch for this box, but it won't be easy.

Have you thought about converting the system to use a cable shifting operation?
With some creative bracketry on top of the gearbox and a gearstick/cables from the likes of a Bedford Rascal (which I happen to have in the shed) you could easily have the necessary movement in both directions with a lot less work. If you could find a suitable gearbox that already uses cable operation you'd be laughing!! |

Hi Bryan, I thought about that but couldn't work out how to make cables operate any of the gearboxes available for the old v6 engine to be honest. I think the best solution for me is the sequential box as it solves the gear ratio as well. I'll start saving now!
