I'd get pulleys (underdrive crank, overdrive water pump) and a lightweight flywheel + upgraded clutch kit. Higher clamping force and better friction materials on upgraded clutches means a more firm clutch engagement - a difference you can absolutely feel. I wouldn't worry about the drive shaft until the center bearing on your stock one fails.
That's all I'd really go for man...any more money spent will be like paying for bread crumbs. Get the rest of the car in shape - there are tons of things to do beside engine performance. Subframe and differential bushings, upgraded sway bars and bushings, coilovers and adjustable control arms/traction rods/tension rods, wheels and tires, hids, and body mods/aero (front bumper, wing, rear bumper, whatever you like man). And of course there is always SOME maintenance you can do...fluid exchanges, fuel hoses, power steering hoses, fuel filter, brakes, the list goes on and on.
That's basically my gameplan...I'm spending some money on performance but not a whole lot. I really want to get to my suspension...this car is gonna be prime when I get to the TT swap!
PS - don't you have a hesitation problem?
