To be honest mate i would leave well alone,going back to my renault 5 gt turbo days(just had a count up in my head and that was 16 years ago)its causes more trouble than its worth.you would need some sort of performance head gasket to start off with to cope with the increased boost a larger intercooler to feed it with greater amount of cooler air needed uprated hoses and things just to cope,i wish i never started going down that road as i ruined the car,yeah it would out perform cosworths and the like but every 1000 or so miles it would let me down some how,usually over heating because it just couldnt cope with all the extra heat created even with things like a larger sump and bigger rad.that was a petrol car though and i have no idea how a diesel would be effcted but i know that more heat will be genarated and could melt valves or pistons.At the end of the day i would like my land rover to be reliable and not let me down,have you tried doing the pump mods to yours,some say the difference is amazing.

Has anyone ever tried two small turbos to reduce lag? From memory didn't the Escort Cosworth do that to fairly good effect? I know Saab run low-pressure turbos to give boost from low revs at the expense of outright BHP figures at the top end.

I spose you could always supercharge it or fit propane, water injection, etc.

I was under the impression the escort cosworth came in two variants, an earlier large turbo and a later small turbo. To the best of my knowledge they never ran two together. Im talking about the road going versions, what happened in the competition version could be completely different.

toyota supra variants came in twin turbo configurations, but evidently they were limited as most end users remove the setup and fit a single large turbo instead

With respect to the mindset of most Supra drivers, they're more concerned with big dyno numbers and anodised dump valves than actual performance...
