I know where you're going with this. BTW Mark, even though you have a non-rotary with an auto, you're car is whoopass. Doesn't mean I won't heckle you for it.

I want to apologize to GNX7 for calling his car a kit car. I realize a tremendous amount of work goes into such a transplant. GNX7 challenged me to a drag race in Sac on the 26th. I'm not sure I can make that one, but I would like to see his car, and if he wants, I will run him. I was simply calling him out on his torque comment Re 13Bs. We all share a common thread, and that is we are fanatical about our cars. Cheers to all, Carl BTW, GNX7 call me.

I am looking to start racing in the NASA organization.

My car is an 86 NA sport model. I have the interior gutted and no P/S or A/C. My car is my daily driver. I have a 4 point roll cage and racing harnesses.

My suspension set up is as follows: tokico adjustables, racing beat springs, greddy strut tower bar, energy suspension bushings all around, rear camber link, front camber plates.

Horespower wise I have a header-no cat, and hks cat back. I also have my ports opening off of the air-pump__> soooon to be off of solenoids. I have an electric fan and a larger radiator.

My question is: What class would I fit into? What else do I have to do to be competitive? What other safety mods do I need to do?

I am going to further lighten the car with racing seats. I also already have an aluminum NA hood.

I want to race inexpensively.

Thanks,
Rob

For most racing is the dash required? If I were to make a dash out of fiberglass do you think that would be legal.. If it looked stock.....

For a n/a how light can you make it?

tims

for any NASA race group you will need a minimum 6 point cage not roll bars in the race group. this is fine for the driver's ed and hot lap groups. best bet is to down load the rule book and GCR's from their website and read through them to see what else is needed. things that come to mind: fire system or at least an extinguisher, window net, seat back brace.

check the rules some IT type classes do not allow any modification to the interior and others do not specify. again check the rulebook for your specific race series and sanctioning body.

Silkworm

Like Tim said, you're going to need a 6 point cage to race, but you've got a good start on a ProSedan-1 car there. So far nothing you have is illegal for that series. I caution you on further weight reduction, ProSedan limits you to a minimum weight limit of 2680 with driver and fluids.

Also, make sure your cage design meets the rules for tubing diameter and thickness. If you're not sure what those rules are, let me know.

Racing =! inexpensive.

Sorry, but there's nothing cheap about it.. Leaving aside all the preparation work to get the car ready for racing (which looks to be about 13K now, not including car purchase), I'm budgeting about 800 a race weekend for tires, brakes, fluids, entry fees, hotel, and gas..

13k

jesh good thing I got my car for free.

but I still estimate about 9k for everything exept tires.

Rs4Racer

Silkworm just wondering.. I was looking at your webpage and your dash doesnt look like its mounted the same as stock. How is your dash mounted up?

Silkworm

RS4, did you tally in a 4.88 rear gear setup with Torsen?

It's the same as stock, but on the drivers side I had to cut the far drivers side mount to get it to work with the roll cage. Since the steering wheel shaft is held up by two beefy bolts into the dash, that holds it in ok..

PaulC

Rs4Racer

Nope I didnt even think about the diff.

What major advantages would this give? If Im running about 200hp I think that it would make my gears too short.

The main things I factored in is the engine and its accesories.

The suspension coilovers, swaybars, and that camber link.

The interior rollcage, seats, harness, steering wheel ect...

The body, fenders, hood and bumpers.

mabee after Im finished with everything else I should see how it is and if I need the gears and diff.

Silkworm

yeah, that's reasonable..

Keep us posted on your progress

By inexpensively I meant that I want the car to be leagal for any class and not necessarily competitive! I can do that along the way.

THe track is about 1 hour from my place so no hotel. I have some connections for parts and stuff (fluids tires etc.) and I work half the events so my entries are paid becasue of that.

Beat that.

Unfortunatly nobody here races 7's so i don't know exactly how to go about this! That is why I am asking you guys!

THanks,
Rob

Silkworm

Well, then it might just be cheap for you

Seriously though, get NASA's rules on the cage thickness, and finish the cage. That, a window net, electrical cutoff switch, seatback brace, and a fire extinguisher are all that you should need to get out there and race in ProSedan-1..

Check my website for ideas/thoughts/etc..

Also, go here for additional info (just be careful, don't ask for help with the rules until you get the rulebook, and this is an SCCA specific site, so don't expect a huge welcome from a NASA guy www.improvedtouring.com

Just an idea of how competitive a stock rx-7 is. My brother in his 88 tII with only a few engine mods and no suspension mods was only 9 seconds off of a pretty modded z06 at the auto cross. He was staying on top of everyone else that was in his class. He had crappy tires and tons of body roll. I think if he had just a few suspension mods and good tires he might have been able to take at least 5 seconds off of his times.

phhttttt...

You want torque? Try around 1000 foot/lbs. ...

http://www.germancarfans.com/News.cf...ID=2030304.002

PaulyDee

That was a 1000 newton meters, which is actually 738 foot lbs, which is still respectable. Sorry for the nit-pick.

foko

i debating on whether or not to turn my FD track car into a legal NASA SU (or other "catchall" class) runner. since my setup is already a very respectable track car in open track events, i'd basically just be looking at doing some details (4 point to 6 point, weight reduction, fire suppression system,etc)

can you guys in the know tell me what typical qualifying laptimes would be for NASA SU at laguna seca, thunderhill, buttonwillow and sears. for comparison, i'm turning 1:45's now at laguna. i'd like to know whether or not its worth a try.

also, i'm very confused on the scca rules on where my car goes. seems GT1 or 2, SP, IT E???? man this rule thing is harder than the car set up!! can anyone with some SCCA experience and FD experience comment.


basically it's a FD, single turbo, many modifications to suspension, large rubber.


i love my rx7, but i've had a taste of the barber series racing and some other arrive and drive arrangements. spec miata and even formula mazda are all very appealing. can only afford to do one though and it's probably time to decide.

thanks guys.....great thread.
