I didnt want to flood anyone else's thread with my own questions so
Im askin here, Does Streetport have potential to reach 300+ hp?

If not, What would be a good Bridegport setup,
I want to make a badass NA and want some advice
if yall are willing to give it to me.

What are the disadvantages of both if any
I kno bridgeport kills the "daily driver" usage...

 

Oh god, another one. Hey by the way did you have a red second gen with maroon interior that has rotor7ven sticker on the front windshield? I was asking el nene about it.

 

no im pretty sure that was omee... Fc3sfreek, that was his old car, he sold it

 

your only going to make 300hp NA with a P-port.

 

do you still have it

 

Yep. With a streetport the max is about 200 to the wheels, and that is with a good port job, and a standalone with a good tune. Kep in mind this is also with a brand new s5 motor. With a bridge you can get 250 or so, but it will no longer be a decent street car.
If you want anything more than about 180-190 to the wheels, then you are better off doing a turbo swap.

 

I totally didn't realize this was an n/a topic. My opinion would be to save and go turbo so there is all that room for better performance when its a streetported Tii. But there have been some people posting high numbers on there n/a. I just like to spool. lol

 

P-Port it!!! We need more P-Ported street cars!!

 

just to be curious, and not to tread jack but how much does a p port cost and is it better to run carbs or stand alone with a p port

 

It'll cost thousands, and either way you'll need a whole new intake, manifold and all. The only PP manifolds I've seen are for Webber's. You can get Webber style TB's though.

All else being equal, EFI is better, you get more control of the engine, allowing you to optimise it everywhere, whereas a carb is a compromise. I've got a PDF of an article comparing Webber style carbs and a Webber style TB on a street port 13B 6 port, the EFI was the most powerful.

 

And about the carbs, there is no reason to run a carb if you can fun fuel injection. A proper FI setup is superior in every way to a carb setup, with one of the major benefits being that you have much better control over timing.

 

As others have said... 300 with a 2 rotor n/a would definately require a periphial port... and you can forget about driving to work with one. You won't make squat power until about 4K or so, and really start to make alot of power until about 8K or so... so fully balanced internals to make power to 10K or so. I know of a guy in raleigh who has a PP 1st gen... and uh yeah, you can't drive that think in traffic for ****.

 

ok well any one who builds engines in florida that could tell me how much a pport rebuild would run, and how much the carb, and the fuel injection set up would run. if you know of any good places in fl let me know. i have an s4 vert (running) and an s5 coupe(blown coolant seals)
thanks

Blake from Pinneaple Racing seems to think P-Ports can be very streetable. He's done it... alot...

thank you guys for all the info, any more thoughts on Porting, Periphial, street or Bridge, pls comment or ask questions so others can answer and i can read, i really enjoy learnin about the rotary thanks alot once again guys

 

you can't "rebuild" into a pport... its a completely different engine. I guess you could block the side ports, and drill a hole into the chamber. I honestly don't know.

Here is a pport rotor housing...



Now obviously, since you intake port is peripheral like the exhaust the side plates will be solid (no intake ports).


Juiceh... I guess it really does matter about thinks like intake runner length... the FB i've rode in with pports sucked. Very hard to drive "easily" around traffic... stop and go, etc.

 

Honestly, if you have to ask these questions, a bridge or peripheral port is something you are not ready for. Stick with a street or stock port for now and the move onto more radical porting when you have the experience needed to tune it (and assemble the engine).
