It's looking good for a turbo conversion, buying everything for a st 170 engine conversion, people know how much 170 items are worth and will charge, a turbo conversion will be cheaper, and for me was it was always down to driveability, reliability (daily driver), and fuel / running cost. There are pros and cons to all the above, but i have a decent MK1 1800 and at this point cannot afford to shell out on a ST170, full car or just engine conversion.

Thanks for all the insights and comment, feel free to carry the pros and cons of various foci.

Mark.
