line between streetable and non streetable
 

I´m a little confused when YOU think the car is streetable and when it´s not. Is is just the power on the wheels or some factors that makes the car difficult to drive. I believe the car can be streetable even it has +500rwhp.

That line is different for everyone.
But a grabby clutch, peaky power band, and bone jarring ride make for a bad street car IMO.

I would say hp is fine whatever you can handle however I would emagine it's not streetable when there is no usable low end so that you constantly have to rev it or keep it reved at at a certain rpm. Of course if any of the legal stuff is missing as well (blinkers, lights etc...)

There are MANY streetable cars with 500+ HP... sadly, most of the RX-7's with those numbers are 3rd gens.

Its all in what you are willing to put up with.

i guess you are asking our opinions on "Streetable"

I would say that reliability is the #1 factor in a car beeing streetable. If you can't cruise the circuit without the thing breaking down, overheating or stalling at every light.... its not streetable.

Therefore, making a second gen "streetable" from that standpoint, with 500HP, is possible, however, its going to cost a LOT of money... a LOT of money.

Also, remember, with the miracles of modern technology, its possible to run your turbo system at about 250HP of day to day driving, and through the use of boost controllers and stand alone ECU's, juice it up for 500 at the track.

One of the problems with getting those kind of HP numbers with a Rotary is porting, which usually throws your idle to hell, making stop and go traffic a real PITA...

hell i made my 91 n/a nearly unstreetable by just doing the tb mod and having headers that were not bolted down tight. it ran awesome past 3500rpms but sucked in traffic and it was SO loud i couldnt stand it and the tb mod caused me more idle problems than i could count. luckily the pd failed not too long after so i get to start over but i learned my lesson on doing 'racing' mods to my car. basicly bolt ons are the safest way to go along with a steetport, any mods taking away mazda's idle controls really suck and you only gain a few hp if any. just my experience.

and theres variations of streetable are we talking daily driver streetable or friday night street racing streetable?

A mild port and a nice exhaust will still be very daily driverish but if ya start getting into bridgeports, throtle body mods,superlight flywheels and 3 puck clutches and full coil over supesnios id have to say track only.

But hell if ya would love to have a full blown race car that you can drive to stop and shop in go for it, its all preference and how comfertable you want to be while you drive

Simply put, If I can't jump in and drive it anywhere I want, anytime I want, without special preparations for driving, it isn't streetable.

Streetable means daily driver or non daily driver. Non daily driver you can have it ass bad as your wallet can handle. I have a 6 puck clutch on my car and its no fun at the lights but crusing its great. I can dump the clutch down shifting to second gear and bark the tires easy as hell and it feels like I don't even need brakes. But my daily driver is a Olds Aurora so my car can be down for repairs and upgrades and I am not catching the bus. If you can afford it get a daily driver if you want to play with your 7 because it is not a daily driver in my opinion.

Streatable = When is does not break your neck on light.

I agree with this sentiment. But my 'vert would then be disqualified, even though I have a perfect idle with a/c and power steering, because the friggin top leaks!!

I consider having to put trash bags over my seats special preparations :D

That definatley qualifies as not streetable in my opinion. I must agree with a previous statement. Streetable is what you can handle and when you can hop in and drive without any special modifications

The definition of streetability is entirely subjective. You have to decide what you're comfortable with. I used to think that stiff coilovers, 120+Db exhaust and crap-ass off-idle response were non-streetable until I drove Blue TII's car for a while and felt the INSANE power and the amazing handling. (Then he fixed the off-idle response problem... :D) Now I think anything short of a BP with a puck clutch would be fine, as long as the exhaust isn't much over 100Db. (I have this aversion to being arrested, and I'm kinda fond of what's left of my hearing) Others would say that a bridge would be a perfect commuter car, even if they have to take out a second mortgage for the fuel. I say make the car as hardcore as your wallet and sense of comfort can stand and drive it like you stole it!
