20v Turbo Conversions are around $10,000 and that will get you to about
400hp I would expect that a 10V Turbo conversion would be around $8,000.
I don't think that the 8 would fit and it's performance potential is much
lesss than either of the I5 turbo's. A P-car engine conversion is also
going to cost as much as a Audi conversion. I'd go for the 2.5L kit and
work on the motor from that angle.
