Re: another XF turbo thread... sorry
you can do it two ways, build yourself a stock motor with a decomp plate or spend $$$$ and build yourself a killer engine, such as forged pistons, rods, head work, cam etc.
The standard computer wont do, aftermarket is the way to go.
Genuine AIT manifolds still can be found in the trading post, or you can get onto an exhaust shop or some who specialises in turbo manifolds to knock one up for ya, wont be cheap thou.
Other things you should look out for are, intercooler costs, radiator(bigger one needed) fuel pumps, injectors, gearbox, diff, etc.
