What do you guys think is the most you can coax out of a street-legal, all motor (or should I say... all-rotor, HAhahaha!) RX-7??? I'm just curious how much N/A power these things can make while still bieng street legal in the smog-nazi state of california. I'm facisnated with rotoraies but have doubts about thier reliabilty after hearing that you have to tear open the engine if you damage an apex seal.

oooooooooh... i wanna hear this one too!!! *but for me, street legal doesn't matter*

i'd say about 350-400 hp, but this will only happen if it is tuned to the max...well mildly, wild is just 500 hp with no turbo one of these rortary's.

If u wanted to do a 13B non turbo and get mega power u would have to peripheral port it. U could prob get around 400hp at the engine which is pretty good for a 1.3L. BUT..... The car would not idle under 2000rpm, would use a hell of a lot of petrol and would be the loudest mofo u have ever heard!
Would rev to 11 or 12,000rpm tho. =)

who told you this, that it will rev to 11-12k rpm's, that is not true it will go to 9-9.5k top's(non-turbo).

Mate, a Peripheral port will rev to 11,000rpm easy. Have u ever been in a PP? Is totally diff to any other sort of port out there. U r making the intake peripheral as well as the exhaust (as far as I know) which totally changes the cars characteristics.
The car doesnt make any real power till about 8,000rpm.

As far as I know, the rx8 is set up in a mild peripheral style also.
Redline on the rx8 is 9000rpm, and thats on a factory car. An interview with the designer said that they had the car redlining at 11,000rpm but they had reliability issues.
A PP that u get a workshop to do is the highest state of tune u can get on a NA engine. It will rev to 11,000rpm easy and still be making power.

12 kinda throws me, 11 seems like a lot but i would believe it. Seems more reaslistic to be around 10, either way, if you put the money into it, I think you could probably get around 350 or 400 hp out of it.

11k rpm is still to high I've gotten the rx7 that I owned single turbo to 9000k rpm, and my car had mod's up the ass.

True, just like the GTR and 22B that you have. Also, a PP reving to 11k, easy....... heck, if they can do it with a straight 6 twin turbo.........

EVomaniac!?!?! DO U REALISE THAT A TURBO 13B AND AN NA PERIPHERAL PORT ARE TWO COMPLETELY DIFFERENT ENGINES!?!?!
The standard intake that u normally port to make bigger is totally filled up and is replaced peripherally where the exhaust port is. U cannot compare a 13B turbo as the ports are in completely different spots. DO U UNDERSTAND!!!!

A turbo engine is never gonna rev that high, thats why URS COULD NOT DO IT!!!!

Please dont comment if u dont know what ur talking about.

Woah dude, chill out don't hurt the guy lol @_@ Anyways, rotary engines are really interesting :jump:

Look at all the posts EVOMANIAC has made throughout these forums in Lancer, Skyline, rx7 and supra and u will not listen to him either.
Look at his, "13B's have 3mm seals STOCk" thread.

He stopped posting here for some reason, maybe everyone found him out on his total BS answers.

Yeah, on the rx7 boards there was a guy Soul Assassin that pulled 600hp out of his N/A. Well i'm pretty sure it was N/A. All i remember is that it was a fuckin FAST FC.

oh yeah, it was PP toom iirc. But he had it in japan, and has since parted out the car.

Such a shame.

As far as I know, the rx8 is set up in a mild peripheral style also.
i was under the impression peripheral ports and side ports are very different.

Yes.
I just looked up on the rx8, it uses both exhaust and intake side ports.
So where the intake is in a normal 13B the exhaust is too now. I was thinking it was the other way around. Both where the exhaust port is.

But anyway, the most power you're gonna pull from an n/a and still pass cali emissions is maybe 200.

Sorry.

i agree with steel for the most part. don't listen to all of the porting talk because once you modify the ports, you are already going to fail emissions testing.

we have one here in Los Angeles, in a RX2, the tach we use stops at 13,000 rpm but the motor keeps going, it does a consistant 12.10 on the 1/4 mile and it is daily driven, ohh yeah.........

I forgot to add the man who daily drives it is about 60 years old..... rotary love...

Not totally true, at the shop we use here in Los Angeles, we bang out 330 horsepower to the wheels on 3rd gen RX7 with a completely stock everything at 8pounds of boost, and pass smog no problem.
The reason why, is because the ports are CNC machined, no dremel or die grinders used.

where the heck did u get that 9k limit.
my 12a on my 85 has a massive streetport with a retuned stock carb, stock exhaust manifold into a 2.5inch straight pipe with a magnaflow muffler and i pull power all the way to 10,500rpm's and thats with mostly stock internals.
it pulls off a 13.98 on the 1/4

Good statement!

With the right mods rotaries are good for 12k+ easy. As for Soul's car...it's a turbo car not N/A (although N/A is still better to me :)). His car is beastly though. You can find his car here...

http://velocity.isfaster.com/new/rides/soul/main.htm

Unfortunately though his car is now dead :-\

How did it die?

peripheral engines make anywhere from 300 to 400 hp . all the depends on your engine setup. type of fuel injection or carburator?
poor drivebitily for the street .
