Been MIA from here for a loooooong time, but I am finally able to get back to the CGT. I looked around and really couldn't find much useful info about swapping the 3B into my coupe. the info I've managed to find is that I will need;
3B motor, ECU, and complete harness (obviously) which I will be rebuilding top to bottom.
Flywheel from a 200 20VT (the donor car)
OE clutch from an URQ (?)

Is that it??? I feel like there should be more needed to do the swap, as it will be going into a FWD car..does ANYBODY have any insight or experience with this swap? I will be grabbing the fuel lines from the donor car, as well as the fuel pump, as I ditched mine quite some years ago when I did the carb swap. But anyway, it feels good to be back! And I hope some of you guys can help me out with this new endeavor. :thumbsup: :cheers:

3B clutch will work along with the 3B flywheel, you'll need to use a CGT throw out bearing. You'll also need to clearance the bellhousing for the flywheel triggers. Check out my 7A CGT project thread for the details. You'll need to cutout and relocate the battery box for the 3B intake, and then figure out how to fit an intercooler. Probably want to install an LSD too. Even just a 7A fights for traction with sticky summer tires and dry surfaces.

Aren't the 10vt and early 20vt flywheels the same? The trigger pins are in the same spot. You might look for a 10vt flywheel, they are easier to come by.

Glad to see you back! Can't help much with the build though, I'm more of a 10v guy.

As for clearanceing the trans for the pressure plate, would it be possible to use the spacer typically found on the 01E?

No need to clearance internally for pressure plate. You have to make cutouts for the crank sensors/bracket on the side of the trans bellhousing (016/01E already have the, but 093 doesn't). Pics in my thread.
