The clutch pedal is annoying if you get a w58 and don't get an sc pedal. I used a MKIII supra pedal for mine but had to do some modification to it so it wasn't hitting the footrest on the left. I eventually got around to taking it out. If you're going to build the car your tranny choice should work backwards- desired hp=what tranny you use. I regret my w58- I have to drop it back out now or it'll blow the first time I miss a shift. w58- low hp, r154 or v160 getrag 6 speed- much higher hp (yes, r154 needs 1j bellhousing and I think you have to mod the shifter but you can find the tranny's cheap on ebay), getrag is expensive, and you can always go with a th400 or boostlogics built auto (which I believe is a Turbo 400). If you are low on funds I suggest skipping the swap altogether until you have more cash and can go with something better than the w58.
