I know that semi PP and boost is not uncommon but i was wondering if anyone has done a boosted full periphrial port, as its going to be most likely cheaper for me to build a full periphrial port then a huge street port anyways im thinking that that is the way im going to go for my 79... Ive also narrowed down the type of pink that i want to paint it, yes i said pink ... dont have to worry about being accused of compensating for anything if im driving a 30 year old 200,000+ mile pink mazda, and it will help with anti theft (whos going to steal a beat up *** pink ferking car anyways ??? anyhow, if anyone knows of anyone that have done this motor combo, i would love to see it...

A full p-port will in no way be cheaper than a street port. Stop dreaming, think about it for 10 seconds before posting. This is one of those times where if you have to ask, you can't / shouldn't do it. How could simply grinding on a plate enlarging the stock ports be more expensive than, filling the plates, filling the housing's coolant passage with material, drilling a hole through that material and housing, having the intake ports specialty designed, cut out by CNC, welded on perfectly, balancing, special apex seals, competition oil seals and springs, and running a custom intake. Not to mention 2000+ rpm idle minimum, no power until what 5500 rpm, absolutely no gas mileage, extremely loud, life expectancy in the term of hours not miles, full blown EMS, and zero street manner. There is nothing aside from the most extreme drag racing situations where this is useful or needed. A normal 13B with a nice sized turbo can make over 500 rwhp with much less work in almost stock forum. If you just want to do it to do it, have fun. But there are much better ideas, especially if you are thinking about money or driving it on public roads at any time.

Many, many people have done turbo p-ports. But these days most drag racers favor higher boost on ports with less overlap.

Tweak, p-ports can be very well-behaved and have excellent powerbands depending on how they're set up. It's just that most people use really huge ports, and intake manifold tuning intended for racing. That said, for turbo applications, most people seem to prefer higher boost with less overlap these days, particularly for a street car.

anyone that refers to a rotary engines life span in hours instead of miles probably knows little to nothing about them, i already have the special apex seals, one piece 3mm ceramics, brand new, paid 850 for them, and i live close enough to pineapple racing that i can drive there whenever i feel like it, that and rob will most likely be the one that puts the motor together for me, and he said 5500 before i bought the apex seals, so i can get a race prepped pro built full PP 13B for under 5 grand now.

Correct me if I'm wrong but life spans go something like this:
NA>Turbo>Higher boost>Bridge Port>PP
[with NA/Turbo/Higher boost optionally having normal porting]

Generally what I've heard is that PP engines live short glorious lives.

[Also, despite Tweak having gone evil - his previous engine was a nicely boosted 13B ^_-]

Oh and in response to your original question... http://www.youtube.com/watch?v=GLLQA2Bh1CA There's one! ^_^

Indeed Derekcat.

A p-ported rotary yes. Yet you started a thread to see if it's possible to boost one? Seems weird if you already know everything about it. *shrug*

From mazdarotary.net:

"This modification has potential for over 300hp but as it is developed for racing, results in very poor drivability, fuel consumption and needs an exhaust system designed to produce excessive noise. Like the bridge port, the PP produces its maximum power past 8,000rpm creating increased stress and wear on components.
And instead of idling at around 1,000 – 1,500rpm for the previous porting methods, the PP engine will not idle much below 2,000rpm and is impractical and virtually unusable on the street.

PRO'S: The ultimate form of rotary porting for maximum power
CON'S: Excessive noise, extensive intake mods, very poor drivability and fuel consumption, relatively short engine life, very expensive, narrow power band"

I don't see any reason why you would want to, 4pistonkiller, but go ahead and do it. Post pix when it's done. At least it will be loud....

My pport drove great on the street,and I say drove because the car is apart for paint,most of the info read on the internet is BS.tuning is everything.samed with a turbo engine,piston or rotary,when you are at the edge and pushing it and you make an error,the engine breaks.also,my pport makes sound at pir after 10 pm,so again I call bs on noise from a pport.and lastly my engine has been together for a decade.I did take it apart over the winter to inspect it.and put it back together with out changing or fixing anything.

yeah, but how much moneys did you spend getting it that way. yes you can probably build the engine itself for under 5 grand, but lets say at least another 1200 in engine management, a good 500-1000 in fuel system, I don't even know what the intake would cost, but probably the cheaper of all the mods, turbo's get spendy, plus you need oil lines possably coolant lines if water cooled, waistgate, a manifold, custom ehaust, and a 7 gal keg tank with a turbo pp sounds like alot of time spent at the pumps, IMO not saying keg wouldn't be cool or anything, just impractical for the street. and pink wtf? and noone can say your overcompinsating with a rotary regardless of power. V8's yes (yes tweek probley has a small ***** but who cares anyway.. JK )

Anyway street port wouldn't cost half the amount, and I agree if you had to ask whether or not you can turbo a p port you probley should just stay away from it for now. be a shame to drop 10 g's into your car and have it blow up (trust me, I know but I did put 12000 before it blew)

I'd build a large street port, decent sized turbo, and work out your engine management/fuel system, and exhaust. save you thousands, and still have tons of fun. 300 in a FB would be pretty fast street machine.

I have a semi p-port bridge on the street and believe me when I tell you that it is plenty fast in NA trim. But as these guys are saying Even with a turbo you will need so much muffler that it will not be too fun to drive. I know right now I am loosing tons of power but I don't get pulled over every time I start it either.
