What would you recommend? I will be swapping a 350 sbc into a 1990 740 SE turbo. I currently have an M21 (close ratio) but I am thinking of selling it to get a T5 instead. My engine put out about 380hp. Can a "good" T5 handle the torque? I would prefer a T5 because of the overdrive obviously, but also because the shifter bolts up on top, centered on the tailshaft. The M21's shifter is of to the side and I think that would interfere with the center console inside the car. As for the bellhousing, would you recommend a '84-'88 Corvette bellhousing or a regular bellhousing with a hydraulic throughout bearing such as a Howe or McCleod?

    The T-5 should be able to handle the torque if you are not drag racing it all the time. As far as I know, the best T-5s are not really rated for that much torque, though. (If you make about 360-380 lb-ft). You can beef them up with aftermarket rebuild parts if you are worried, I think you can make it good up to 500 lb-ft, but then at that point you are spending as much as a TKO. Advantages are that the T-5 is still lighter and smaller.

    The stock T-5s with a short shifter also shift nicer than a TKO with a short shifter. I don't know how the beefed up T-5s shift. Google G-Force.

    What other tranny options do you have? Can you use a TKO-500?

    I'm not familiar with your bellhousing options, but I am partial to the hydraulic throw-out bearings. I like the theory behind them, and I like how mine works, but setting them up is kind of a pain. It's definitely more work than a cable clutch, and will cost more.

    Got any pics?

      Greg, thanks for the info. I heard the T5's are ok unless you beat on them all the time. Also, street tires are sort of a safety valve for the tranny. As for the bellhousing, it will depend on how much money the local salvage yard wants for the corvette ones. No pics yet, the car looks kinda rough right now, but it is currently white with the original Volvo body kit. Similar to this one.

      Mine will be black or silver with TSW snetterton wheels.
