if you got a bit of money to play with then you could get someone to make you up all the manifolds etc that you will need.......its very expensive though...
Mate almost anything is possible, if you want some extra kW to play with maybe a supercharger might be an option, because they were options for similar models less custom stuff needs to be made. I suggest you surf the net for a bit and do yor homework
I used to have a v6 which i was going to do up but i was going to cost to much. i ended up getting a vt series 1 stroker fitted with gearbox for 11k puts out 275hp at wheels. does low 13s stock with exhaust. plus if i put a blower on it i can get 475 out of it with stock internals. v8s are in my opinion a better way
Like the others said, anything is possible. You fail to mention if it is a 6 or an 8?
Why get a turbo when there are many aftermarket Superchargers available?
