Exclamation Is my RX7 Bridgeported?

This may seem like an odd question but I'm wondering whether my 86 rx7 sport n/a is bridgeported or just ported in general. The guy who owned it before used to race it and go to autocross events all the time. If you guys can determine by the sound you should let me know and tell me what you think. The car has a k&n air filter, Koni suspension, Cat-Back exhaust, racing beat "race" spark plug wires, NGK R platinum sparkplugs, TRE performance 43 psi fuel pump and a k&n hp1004 oil filter. The cat is still on it and it's cracked so we're going to remove it and also the heat shield is making the additional noise. I took the spoiler off btw to do some cleaning.
here's the video of it too. Also there's an audio format I posted for better listening.

Its definitely not BP. BP will have the characteristic and very distinctive "brap brap brap" idle. Could be streetport or stock port but hard to tell when its idling so high. Its running rough. Does it have an aftermarket ECU? That might be more of a give away.

I'm not too sure if it has an aftermarket ECU. But I'm pretty sure it's street ported. Listen to this and how similar it sounds.
. If you watch the youtube videos just listen closely

At some major moments in the recording there was a sound at a specific RPM that sounded just like the video I sent.

This is my last question. The car weighs 2550lbs. With the K&N airfilter, Catback exhaust, cat del and the header and everything else I said. Do you think it could be making around 190 - 210hp by theory?. And if it is will it kick you back if you're a passenger? When all said and done.

It should be a fun car that handles nice, goes hard enough to be fun and makes all the right noises. That said a V6 camry might beat you in a drag race but they will be floundering in corners with their slush-box auto transmission and crappy front wheel drive and will have to make their own broom-broom noises while you are happily steering from the rear and forming a special bond with your sports car as man and machine.

if it's hp numbers ur looking for, put it on a dyno. it's the only way to know for sure what it's putting out to tell ur friends. but that 190-210 is possible.

Thanks man. Appreciate it. Do you by any chance know why the side of my motor on the silver top of the engine bay says "1 326" ? Like as in one thousand three hundred and twenty six.

Likely closer to 170 hp, sounds streetported though.

There was a member that had a fully built street ported 13b-re, aftermarket ecu, fuel, etc.. And he made something like 210-220.

If you can furnish a photo of what you're talking about, then that would be ideal. However, I can speculate that what you're seeing is maybe "N 326" with a partially worn out "N" - and that is the part code that prefixes many FC part numbers.
