For Sure man. I also didn't know you meant a built rebuild, like with forged internals n shit.
If you really think you'll be happy with FDW, then giver, and if you have the money to go to a completely different ECU, then right on.
The FWD NT tranny has shorter gear in it. In other words, when you start making more power, they're going to be too short for your application. The components themselves are also weaker from what I know...a nicely tuned forged motor will eat it.
The swap isn't that hard, just for the parts you have to get, and the money you have to spend, you'd be better off selling it and grabbing an AWD. So if the swap is really what you want to do, don't be discourgaed.
What turbo are you going to be running? 2.0l rebuild, stroker, or destroker? Are you goals for the car just a fun street car, or some autoX? You mentioned putting slicks on it and drag racing it? Where? I wish the island had a more competitive drag scene. A season or something.
Good luck with it all tho man. If you want aTurbo FWD tranny, I have one for sale, as well as the linkages you'll need.
