Swap the flywheel from your N/A to the Turbo II, and you should be able to use the rest of your N/A drive line after you do that. This is what a reilable person posted to me.

See above...but note that even if it fits (I won't confirm this), it may be too much power for the tranny to last a while.

You would want to go with a TII tranny, the N/A tranny, like pfsantos said wont last too long

I wasnt saying that the tranny would hold up! (Maybe low boost and no hard launches!) Just stating the fact that it could be done for him.

I know Landers was putting clost to 300hp into his with no problems.

Mine has been going strong for 2 years now with no issues.

You can keep the rearend, but you must use an Automatic driveshaft. The automatic driveshaft is a little shorter than ideal, but it will work.

I think MazdaTrix also makes a driveshaft specifically for this application.

If you have an LSD rearend, I think it will hold up to 250-300 horses, but I wouldn't. Just swap over to a T II rearend. <-- that being said, I have never tried that much HP through one of these rearends so I should probably STFU and let somebody answer that has tried.

As mentioned earlier in the thread, the TII engine will bolt up fine to the NA drivetrain if you swap on the NA flywheel and clutch assembly. That's all there is to it. Any 2nd gen engine will match any 2nd gen transmission as long as the flywheel and clutch are swapped to match the transmission.

As for the power handling of the NA drivetrain, I'm currently running 13 PSI on a GT40R on my bridgeported engine with an NA drivetrain behind it...
