1987 toyota supra NA

I just recently bought a 1987 toyota supra Na 5spd with 68,000 miles on it. It was sitting in a garage for a long time in new york. When i start it up its a decently rough start and it puffs out a cloud of blue smoke. Ones it's running it runs amazing, shifts flawlessly and everything runs perfect.

I was wondering how i could increase horsepower. ANYTHING besides turbo that will help me with gettin some horsepower. and last, whats the fastest they go stock and can i get a new trannny that will push more out? any help with making this car fast without turbo would be very nice.

I bought a Megasquirt for my supra. Its a stanad alone computer tuning device that you hook up to your car. Its pretty cheap. You could give that a shot. You gotta be smart in automotive electronics and computers though.
