Well, it is sorta low hanging in terms of cost effectiveness. I would get you a s1-series stickshift parts car (~$300) and a 99 manual ECU (~$30) and swap in the tranny and clutch pedal and shifter.

FYI, I didn't swap the brake pedal on mine (large pita), I just used the cutoffwheel to make it the right shape/size and moved the rubber pad over.
