I have an '89 N/A that I'm getting an engine for. If I have TII rotor housings installed and have the intake ports enlarged, along with 3mm apex seals (I think), about how much power will I be putting to the ground? Also, later I will be getting a really free flowing (by free flowing I mean illegally loud) exhaust and intake...about how much might I be getting then? All assuming that the rest of the car is in fine working order.

 

Sorry.... can't help

 

Your saying an NA with turbo rotor housings and 3mm apex seals.....hmmm well the turbo rotor housings are a good idea the 3mm apex seals im not a fan of but you could be looking at around the 200 mark if you play your cards (parts) right and have the right port (at least an aggressive street port) done to your motor....
