I just got my motor back from maz-sprint in Brisbane, a 13b race bridge port with all the good stuff.211.6 bhp is realy good for a B port so if you want a kick *** motor give them a buzz

The minimum I would go on the exhaust side on a bridge ported motor would be a P trim wheel with AR 1.00 housing (1.15 is better). CHEAPTURBO.com has a TO4S for $725.

rx2boy i have already found some one to do the porting and and those are some nice numbers what all do you have done? IGY you seem to know your **** i was told that the way my motor is built (just a normal rebuild) i could not run over 12psi i dont know why if i have it tuned correctly. what all comes into play when pushing for high(over 375) hp engine wise?

How much boost you want to run is related to how much FUEL you have...not necessarily the engine. Of course, tuning and timing are important as well.

TO4S, stock FD motor, 15psi, 550/1680injs, there are people seeing 400rwhp. Good side port, 15psi, TO4S, 460rwhp, I personally tuned this one.

would the se engine handle 400+hp? also what would be a good ems to start out with i am new to tuning dont want to have any serious problems

To tell you the truth, I don't know much about the NA rotaries, the last NA rotary in Japan was in an SA. You can work around the high compression of an NA motor with experienced tunning, lower boost, and water injection. Since you are doing a rebuild, I would shoot for lower compression rotors out of a turbo motor and some turbo rotor housings.

What's the difference between the n/a and the turbo housings becides the sleeves?



I'm with IGY- if you want hp you need AT LEAST two things. The fuel supply and tuning. Once those two are in place the HP will be there if the rest of the system is built right (aka no t3/t4 turbo)
