Mate, assuming your talking about a CVH RS turbo engine, it has been done plenty of time's now and it's considerably straight forward. The hardest part is probably getting the wiring loom sorted out.

You'll also need to modifiy the position of the starter motor if you're planning on using the Ka's IB5 gearbox, along with that you'll need an engine mount fabricated and possibly a custom charge carrier as this often foul's the bonnet.

Hope that help's.
