Never driven a normal petrol turbo, so presumed that all turbo cars drive the same, ie on/off 
I liked the power delivery of the 3.2, but like I said, am considering something left field, rather than particularly boy racerish 
The idea being to create a reliable daily driver that shifts when the mood requires. 
I currently (for the last two years) have owned and driven a 2004 SAAB 9-5 Aero. It's got a FPT (Full Pressure Turbo) and as standard is extremely enjoyable to drive.
There have been Omega's with this engine fitted. Afterall, the largest output Vauxhall/Opel Omega is 207HBP with a reasonable amount of torque. The SAAB 2.3 with TD04 Turbo (as in my car) is 250BHP and 350Nm Torque. Pop that engine in, and YAY!!!!!!!!!! Usining the Trionic7 and with a couple of minutes work, it's 275BHP and 400Nm.
I LOVE LOVE LOVE the Omega, especially the 3.0Elite MFL (The best car to have), but it's not got half the balls, no matter what rev-range to the 9-5.... and the 9-5 is almost as big too.
