IMO, your'e opening a big can o worms by throwing in a 3.3. Better get a power screwdriver and a whole bunch of spare drivetrain parts ready. I doubt the car will handle the engine for long.
If you need more speed, find yourself a good pull start O.S side exhaust .12-.15 engine or a good pull start rear exhaust .12 with a manifold for a Kyosho FW-05. Definitly more power and speed than the stock .16.
