So i got the 1987 nissan 200sx se-v6. Right now i'm not really worried about the handling cuz it's pretty awesome but i want a little bit more power. I wanted to put the 300zx twin turbo in it with the 5 speed becuz i got an automatic right now. First of all I don't even know if this thing will fit, some say it will, some say it won't. I want to make sur before i go threw the hassle of buying everything. next is the tranny, I wanted the five speed but i don't know if it's better for street racing. I'm not a strip person i mostly stay on the streets. I've raced a few people and won everyone, (mostly hondas), and i don't know how hard it wuld be to switch the thing from an auto to 5 spd. From wt i've read if i buy the engine wt the tranny, ecu, wiring harness, then i jus gotta pull the clutch kit from a junked nissan. Help me out the cuz i really don't know much about this car.
