Opinions on turbocharging a N/A 6 port
Ive heard only a few reasons as to why you should or shouldnt turbocharge a N/A. Some support the idea while others have their doubts. I personally am thinking of taking on the endeavor and rebuilding my 6 port, turbo ready. Anyone here in the forum tried this or have opinions in either direction, I would be very interested to hear them. Im of the opinion that a 6 port motor has a wider power band and high compression rotors, making for a totally bad *** platform for a turbo. Also, I found out from a reliable mazda shop that the turbo motor has the same exact apex seals as a N/A. Im interested to hear your comments!

Higher compression only means that you can't run super high boost. Six port engines seem to do fine with a supercharger, I don't see how a turbo would be any different.
If you do it right ($$$), I forsee no problems. However, doing it right would include the following....
Custom turbo manifold, the stock Turbo II manifold doesn't leave enough clearance for the turbo to fit with the six port intake.
Decent turbo
Aftermarket ECU (Haltech) with fuel system components. I'm not sure how well the stock n/a ECU deals with boost.
Other than that all you really need is some piping and a few other bits here and there. Those are just the main things.
Overall, you'd probably be better off going with a Jap-spec turbo engine and just dropping it in. It would be way more cost effective.

Well.....You can easily solve a high compression problem by installing the low compression turbo rotors. If you went with the high compression rotors you would need to increase fuel delivery and possibly retard the timing...Just my thoughts.

I've been running a na engine turbocharged for a few years; yes I have had growing pains (ie BOOM) but seem to have the problems worked out and have a very driveable setup now. I think as long as you are not going over 10 psi boost a na is the answer because the higher compression rotors give you a little more power off the line.
Just my two cents from my experience
