View attachment 165097 Its cheaper to take the na motor and change the pistons and exhaust valves.
I recently purchased a 182 Barra for no particular reason and no vehicle to put it into, but it was actually quite inexpensive. So I bought it. Now I have a Lotus Seven replica, a Triumph GT6 and the option to get a very nice running MG Midget. I don't usually gravitate towards imported cars, but I recently bought an unfinished 5.0 Spitfire and now it is finished except getting the brakes on the 9 inch to play with the rest of the system. At this point I found out how inexpensive vintage British sports cars are and bought a raft of them. It appears any of these might fit the Barra engine into it other than height but I won't mind being able to see the top cover.
To the point, you mentioned changing pistons and exhaust valves, is that critical even if I set it up for mild boost pressures, like 7 to 10 PSI?
Assuming I even bother to turbo it, these cars are between 1100 to 2000 lbs fully dressed in stock trim.
As long as the motor is 2005.5 and up you are safe to run 12-15psi with a good tune.
