As there appears to be some knowledgable people on here regarding the finest lump of alloy the British car industry ever managed to purloin I thought I'd share some of my recent musings.
My beloved, and currently dead due to gearbox misbehaviour, Range Rover Classic is a 3.5 with an intercooled turbo setup.. It's blueprinted with very expensive Omega forged pistons as it ate a couple of the original LR ones.
This gives me a bit of a headache. I'd like more power but the 3.5 pistons aren't useable in the larger capacity Rover V8s and I very much doubt 4.6 pistons / liners would appreciate the turbo forcing them to work for a living.
So, how can I get more power / torque out of it without replacing the pistons? I remember something about a Buick crank that increased the stroke somewhat, but I imagine that'll be more expensive than putting manly pistons in a 4.6.
Also, is there a stronger auto box that'll bolt in? As soon as I got the engine running properly it nuked the 'box. I'd have thought the ZF HP22 would have managed 320 lb ft easily enough, I was obviously wrong.
Suggestions please - apart from "Behave, 330 bhp is enough"
