Ok.... I want to get into road racing (going fast curvy track) all that type of stuff.
I dont know much about the 13b so can someone give me a list of stuff that I can do to a N/A to give it the speeds I will need for this type of racing?

intake, porting (probably a PP?) and headers/full exhaust, and tuning? lol.

Oh, and good brakes, good tires, setting up the suspension, a roll cage, and most imporatntly of all...

DRIVERS SCHOOL Best thing you could ever do for your car.

Haha im going to some racing school some time this summer..
whats the difference between a street port and a "PP" ?

jarred

the "PP" stands for Periphial Port...but its kinda hard to explain, but here goes : a street port expands the existing ports to a degree but periphial porting does away with the stock ports and has it coming out of "the block"...does that make any sense? i think u have to see a picture of each to understand

Nihilanthic

Peripherial port = the equviliant of a race cam, the car wont even idle lower than what, 2K rpms? LOL

Really really powerful, but nooo low end. Also, reliability is **** when you do that, apparently. But, well, hey, itsa RACE motor, have fun with it. Plus, NA rotaries are surprisingly durable.

I would suggest going into a slower class like ITS(at least I think thats right) with I am not sure if you can even port the motor, and it you can it is just a street port. Concentrate(sp) more on the safety/handling/ and reliability of the car instead of big hp.

88GT

ITS= Stock ports. No internal power mods at all. You even have to keep the dash in that class. The BMW's are hard to beat in ITS but can be done at the right track and well setup car.

Before you even think of what to build, and how to modify it, you need to go to some local races. See what classes there are in your area, and how well they are subscribed. Racing isn't really racing if you are alone on the track. Improved Touring A and S (the faster of the IT classes) are usually well attended in most regions of the country. These classes are within the SCCA realm. Other organizations such as NASA also have similar classes.

Once you decide which organization(s) you would like to race with, purchase a rule book. This way, you will be able to build a car that is safe and legal.

Check out www.improvedtouring.com for more unofficial info. Just ignore some of the typical "web forum" antics and BS.


have fun either way

So is it possible or even worth it to make a car you can road race but is still street legal?

grantmac

No, the closest your should really get is HPDE or autocross with a street car.

Yes you can make a street legal ITS car but you won't want to drive it on the street much. And it won't be very passenger friendly.

As a beginner you won't really be giving up much performance to the full-on IT racecars because you will have a lot to learn about driving first. It'll probably be at least 5 years before you have the skills to take full advantage of a full-on racecar and that's if you are already an experienced autocrosser. But don't worry you could be a solid midpack performer in 3 years if you're dedicated. So don't worry about top performance, work on reliability and predictability.

I drive an ITS 87 Rx7 that is nominally street legal (we won't talk about swapping the cat in and out all the time). I really only drive it to the track and back but it is nice to be able to make a few changes to the car and then take it for a test drive.

I am a club racer so I haven't been paying attention to the latest SCCA rules. For example, I don't think that the SCCA requires a fuel cell yet. It's highly recommended but I think that would make the car unable to pass inspection. Same with NASCAR door bars.

You need to get an idea of what class in a particular club you want to run in. SCCA, NASA and other local clubs have rules on what engine and each mod you can do.
You can be placed against really wierd opponents by spending tons of money on HP in stock bodies. (Twin turbo Porche or an old 600HP NASCAR Chevy)
I think as stated above ITS" improve touring" is cool or ITA. It depends on you goals.Many people build high HP motors end up running in ITE or SP and more or less are hotlapping cause those are "unrestricted classes" It sucks to get blown by a nitrous & turbocharged jim wolf racing 300zx and you spent a lot of money on a PP that make 275 HP on full chassis. Good luck at your school...be smart and finish not hot and crash.
