a guy with a westie chucked a turbo from the Rover 820 onto his zetec, i remember reading about it in PPC i think it was, sure he just used an extra
thick gasket to get the desired compression.
He found that the standard Rover820 inlet actually lined up better than the zetec one!

0.9mm copper gasket will give you a compression of 8.3:1 on a standard engine.

The adaptor plate for the Rover manifold to Zetec head is available off the self along other required bits.
The plate itself is about 80 pounds I have the URL of the the guy that makes it somewhere

Also the inlet manifold dosen't have to be off an 820 Turbo or Vitesse Turbo, any manifold 820 (or 220 or 420) with multipoint injection is the
same.

Forged low comp pistons are best, but expensive (£400+). Keep an eye on ebay for steel decompression plates - you'll need a 2mm spacer plate
used with a standard head gasket to get the compression down to 8.2:1 and I paid £45 for mine.
On standard pistons this should be ok for up to about 10-12psi of boost.
Rover 820 turbo inlet port spacing is perfect, but won't fit under the bonnet line on my Tiger (miles too high) so I've gone with a
Griffin Power inlet manifold which should just about fit.
The rest of the bits I've fabricated myself, like the exhaust manifold, exhaust downpipe, flanges, mounts etc.
Don't forget the cost of all the extra bits you'll need, like oil lines, fittings, wastegate, dump valve, amal valve, inter/chargecooler,
etc etc - it really does add up.
I'll do a full writeup one day if it works, otherwise I'm going to sell the whole lot for scrap and cry for a week about my wasted
winter....
Hope this helps,
Tom
