I've been yo-yoing between independent front and going for solid axles all round. It looks like independent has problems if you're trying to do it cheap and with decent travel, so back to solid axles it is.

I'm looking for ideas for which solid axles and gearbox/tbox to use. It's for a trials buggy, 200 bhp, 33" - 35" tyres, and 850kg - 950kg target weight. I'd want something with lockers available front and rear and a range of gear ratio options either in the axles or in the transfer box. I'd like to avoid compound angles in the propshafts, so ideally the tbox and axles would have the same offset so the propshafts run straight.

Lighter the better really...

I've looked a lot a Hilux and the 4Runner/Surf, but the solid axles were only on the Mk 1 (upto 1985?). Not sure if these axles are still available and how knackered they would be.

EDIT: UK Hilux has solid front axle until 1997, phew.

Done some digging on Pirate4x4, damn those people know how to rip each other... Ok, so, the early solid axle Toyota axles are still around, and good for 200 bhp and 37" tyres. I'm planning on 35" tyres and possibly more than 200bhp but I like the idea of Toyota... lots of them around and lots of upgrades available (I think).

Still open to alternative suggestions. Also, not currently sure if the Hilux gearbox and tbox are up to the job, but should think they are. I hear that one of the tbox shafts can break but I've seen some upgrades for that.

I know squat about Land Rovers so haven't looked at any Landy options.

With budget, so long as it's a 1990's car or from the nought'ies then I can afford to buy a written off one to use as a donor for the drivetrain. I've always found it's cheaper to buy a written off car if you need a lot of parts rather than buying individual parts from breakers yards.

Nissan Patrol / Safari drivetrains are tough as nails if they're common where you are, might be an option.

You might want to mention the expected torque. Light revy 200bhp petrol will be 130 ft/lbs 200bhp turbo diesel will be three times that.

Approx 140 lb.ft. Maybe a Jimney drivetrain will do wink

I've seen this done, it works great.

Looks like I'm going with the Hilux drivetrain at the moment, with upgraded CVs.
