Correct, missed you were outside US.
UK magazines prefer the S50, the 3.0L version. It has 286hp, but easily tuneable, still OBD 1.They also come with a 5-speed ZF tranny, which is a lot smoother and more reliable than the 6-speed 'box in the 3.2L version. Racers never even changed the 5-speed 'box, but had many failures with the 6-sp ones.
Shop around, try them both, check the history.
