Hi

I'm looking at buying a lightweight, I think it'll be aseries 3?
It's a non runner thats been parked up for a couple of years, it's very tatty but looks all there. Axles look about rotten but it's on a mint galvanised chassis.
Any pointers to a rough valuation would be much appreciated.

If I do get it I have a 200tdi disco which I'd like to use to swap any possible drive train parts over. Has anyone done a lightweight TDi conversion and if so what components can you use/ how much of the disco drivetrain can be used?

All info greatly appreciated

Thanks for that james, I take it you are keeping the series transmission then?
I was wondering if it was possible to graft the LT77 in with disco transferbox for relaxed cruising

involves moving gearbox mounts and guessing you dont want to take an anglegrinder to your shiny chassis

Series transmission is well capable of taking the 112 bhp of a 200 though you need to be gentle with the power off-road if you like your half-shafts.

Easiest way to change the gearing is to fit an overdrive, which with series gearing and a 200 will give you a cruising speed of about 65, though some folk prefer to change the diffs but then you lose a bit of your low gearing.

Thanks Blue beasty, thats good to know. It won't really be used for off-roading per se, just pulling a trailer occasionally and ferrying people and dogs around on a farm.

Also remember that the series front axle is not designed for permanent 4wd. My option would be 200tdi engine with series transmission then stick a couple of 3.54 diffs in from coiler. The ones out of the disco will do if they're 10 spline.

cool, more good info. Thanks Hughesy. It's starting to sound a bit easier than I envisaged which is always a bonus.

if your towing a trailer around a farm then i would leave the std diffs in as i think the 3.54 diffs will be too high geared also std diffs are better for climbing hills you will still get 35 mpg and a top speed of 70 + if you need to go that fast.
