RE: turbo upgrade

no, you were misinformed. Its a ko4-15 and its smaller than the 225 TT ko4-20. You can pick up a newer ko3s for under $200 and its comparabale to a ko4

He may not be in North America. Model years are not the same everywhere.

RE: turbo upgrade

I'm pretty sure the housings on the TT turbo is also different, meaning that they won't bolt up correctly and the compressor outlet won't connect to the piping in the stock location.
