Well it sounds like you need a new turbo regardless.
Buying a new 207 and all the bits(timing belt kits, gaskets, oil & water pumps etc) will cost you around $7-8K, if you pay someone to build it all for you.
If you want to make 300kw you will need a decent turbo - $2k, headers &
tbe $2k, fuel pump , injectors, tmic or fmic. Then you have to decide if you are going to use 98 or e85...
Looks like they sell it in Albany too!
