Well i am debating wether I should try to pump out intense power out of an n/a or just break down and get a turbo engine. but seriously how much power can you make out of an n/a?

Two rotor. I would only go as far as saying ~325bhp which would be around 270ish WHP.

This would cost more than a couple of TII's I would bet.

what would you do to get that kinda of hp from an n/a and would it stillb e streetable i'd like to know because i'm geting a 7 soon and am probably gonna stay n/a at least for a while

Sorry I forgot the HOW part.

That would definately be a non-street car.

Preipheral ported engine with Renesis rotors 10:1 compression.

Probably a carb setup would be the cheaper way to go but for power cheap is generally not the way to go. Try going with some IDA I think is what they TB's are called where it has one opening per rotor.
Custom designed exhaust(no bolt on will be perfect for that engine)
THen get to tunning on a dyno for I would say a good couple of days.

Then hope your engine builder knows his porting enough to provide for that hich of an HP number to come from yor track monster that will make your ears bleed.

Whose car has done this with a 6-port engine? Or even a 4-port?

I remember seeing a post about a 300 hp N/a peripheral ported engine. I can't find the link to it anymore. But I DO KNOW that you can pull 250whp out of an N/a it is just Not going to be very streetable or legal.

Ryde _Or_Die

This is without the use of N20? Try to find the link, I'd really like to see the dyno graph. Also, was this a 4 or 6 port engine?

I don't know if you would even call it a 4 port. Aren't peripheral ports only ONE port per rotor? So it would be a two port?

LOL. If you consider a 4000 rpm idle streetable, I guess it qualifies, plus you would have to have gearing so deep, that you would be cruising down the highway at about 5000rpm. Overall, the engine would be unbearable and probably last about 15,000 miles.

Ryde _Or_Die

Ya, thats what I figured. I just don't want this guy to think that an Na will be close to as fast as a TII without MAJOR mods and unstreetability.

An N/a can pull more whp(modded) than a stock TII. But then again how many stock TII's do you see around.

RoninAutoBoX

Yeah, jsut go 3 rotr if you want extreme N/A power, or hit the turbo for extreme 2 rotor power.

Well comming back to earth to a streetable ride with the most amount of money put into every possible upgrade. Even the ones yielding only 1-2hp you could probably get 180-190whp if you spend a lot of cash doing it.

mazdaspeed7

If you dont know what youre talkign about, dont talk! PP's do NOT idle at 4000 rpm. Its about 2000 with a carb, or 1500 with fuel injection. The powerband is perfectly streetable, and they easily last longer than 15000 miles.

Ryde _Or_Die

He did exagerate, but his points are right on. They idle high, get poor gas mileage, poor streetability, poor reliability. The only thing they do well is accelerate pretty much. And I don't mean the powerband isn't streetable. I mean the emissions/sound part of it.

thanks you guys answered my questions fairly quick I will be doing a swao for a tII engine once I find my gxl hehe. Thanks for the info didn't know the n/a's were that low for potential. My old one felt really quick thought they would have better potential

mazdaspeed7

They have potential, but its hard to realize without opening your wallet WIDE. If all youre looking for is power, n/a is not for you. And why bother getting a GXL just to drop a turbo motor in? It costs WAY more than just buying a TII in the first place. Not to mention all the trouble.
