Anyway, it would be nice to see your car in action. The American Autocross Series runs in the central valley (near Merced) and typically sets up courses that your car would like (as opposed to low grip small courses in the Bay Area). www.americanauto-x.com.

You are right, but this guy doesn't take the time to read about the car before commenting. Opinion is one thing, blind statements only serve to confuse the newer mebers about a competitive chassis. as far as power, I actually planned on running a smaller turbo for AX. merced is a two hour tow, so I will most likely not run there. i did run AAX when it was in Sacramento in my SM 97 Supra. Oka kicked my butt though. I'll be Ax'ing the car on the 13th, on a mid sized course, bad pavement though, so it will be tough since my suspension is set-up for smooth road courses. I think when he said the chassis was probably not a good platform I reacted. Oh well, one outburst a year, I am done

How about you find an event where Andy Mckee is going and see if you can get him to drive your car during a fun run or something to compare times vs. his car on the same course or vice versa and see how yours stacks up against his with the same driver. It would be interesting to see the comparison and the feedback he gives on the throttle response, braking, and handling of your car compared to his. I don't know if you know him but he is on the forum I think, just don't remember his username.

First, let me apologize for snapping back. I am not suggesting my car would be nationally competitive as it sits. I was mainly making the point to the original poster, that a TII is a great platform, and that it had won many national titles in several different cars with at least five different drivers. Not sure when Mckee will be around here, but Derek Butts DSP champ is local, and I think there are a couple others in the region. I will likely make some American Autocross events in Merced, there will amost certainly be Nat. level drivers there, and it would be neat to see what a top driver can do with the car. I also have a nearly Nat level guy that runs locally, but he is driving an EVO, so it would be VERY different for him. Anyway, what is your name, and where are you out of? Thanks, Carl

The original topic of this thread was ultimate RX autocrosser. You said build a car like yours sort of half jokingly. I wasn't saying the 2nd gen isn't a good platform. I know it can be a pretty competent autocrosser, ultimate? Well I would have to give that to the FD at the moment since the only class where I see that RX-7's are winning nationally are the FD's in SM2. I don't pay attention to every class though so there might be some others where RX-7s are dominating nationally. First gens seem to be able to do pretty well in CSP though. My point for getting to test your car against Andy Mckee's is to see how the time of your car would compare to his SM2 RX-7. From the info on your car it sounds like your suspension would be a really good setup, but like I pointed out a lot of the stuff you have done regarding power, brakes, etc. you would want to be different for autocross. In my experience, nationally competitive drivers, even if they have only raced a CS miata or slower car before can hop in a high power car and drive it very good, because they are still good drivers. They won't be able to get that last 5-10% out of the car without a lot of seat time, but they will be able to drive it fast still. I live in Washington state right now and compete in the NWR-SCCA as well as three local club seasons, WWSCC, BSCC, and SSSCC as well as national SCCA however I am not all that great of a driver yet. I am the novice chair for one of my local clubs that does 10 events a season and am a instructor for 3 novice schools held around the region every year. I won't be racing in California until next year when I go down to the Atwater NT, Atwater Pro Solo, and San Diego NT, that is if my girlfriend and I both get competitive co-drives. She probably already has a multi-national champion driver who is buying a new competitive car next season she will probably get to co-drive with since she is better than me. - Quentin Christensen

Hi Carl,

The TII is a proven platform for BP as evidenced by the Tripoint car and Steve O'blenes' car were both winners. However, I think that the FD is probably a better platform, it's just no one had taken the time and money turning one into a proper BP car, yet. That's changing as Jeff Kiesel from San Diego has put a tremendous effort into his FD. It was pretty amazing last year even with some serious problems, and if he gets all the new work done before Nationals this year I think it will be something to see.

In any case, try and make the Atwater (AAS) events if you want a real autox comparison. Not too many higher prepped cars go to the Bay Area local events as the sites are too bumpy or gravelly.

Thanks for your input Andy, I am focused on road racing right now, but I do have plans to create a second map with a somewhat smaller turbo with extremely fast response, and ~400rwhp for AX, vs 500 for road racing. We shall see, I am testing this weekend, so I'll know if I can reject ~450-500hp worth of heat @90* ambient for 20 minutes at a time. Carl

in reply to people saying carls car wouldnt do good at auto-x BS!

huge tires and light car.

my friend in az had a pretty stripped fc, i think like 420rwhp and 275 dot slicks or something like that. his car was one of the fastest out there all day at autox, only a miata and a couple z06s, i think autox is the most of what he races his car in, could be mistaken though.

*sigh* I love the trash-talk and over sensitivity, this is a fun thread.

I'll let Jeff Kiesel know that he's got some competition coming. :-) I'll see him and Steve O'Blenes this Sunday (he's now driving an STU M3). From what Steve and Robert (codriver several years) have said in the past, his car made too much power anyway to be really usable in Topeka. Believe it or not, they ran the off-the-shelf AWR/Mazdaspeed ITS suspension for two years before having Guy build them some nice shiny suspension bits. BP is a very difficult class, as money and horsepower (ala Kiesel) don't always = winning. There is no guaranteed formula in Solo racing, even if the odds are heavily stacked there's always a raincloud in Kansas that'll fix that hehe.

Good luck this season everyone, and keep hitting those Evo schools and practices...no matter the horsepower, we ALL need them!!

Back to the original thread, a well-prepared CSP 1gen car with a fuel injected 13B would be my best bet....again, you don't have to chop a car apart or put a V8 or turbo in it to make it go like stink around an autocross course. Bob Mosso in his '81 used to do quite a number on the current CSP ProSolo winner's car (Schenker's miata as driven by Eric Clements) and certainly a top-10 PAX car/driver combo in the ultra-tough Cal Club Region.

I see alot of bad advice here and only a few good ones

I agree with Dave turner


get a 1st gen whatever year you prefer.
prepare the chassis
have someone build an NA 13b within the rules of the class you want.
ive ridden as a passenger on a few 200+HP FB 13b's that were street prepared and were ungodly fast with some manifold work and fuel management.
but some 225/45/13 hoosiers or whatever tire you like along with the suspension to make it all work and have fun.

fun is the important part here.

The mods you said you want to do are the good ones. For the engine, I would have a heafty street port, with a second gen turbo added on, and a supercharger from a Ford Thunderbird SC, with a full exhaust system and maybe twin mikunis. This would probably cost around 5k if you did the work yourself. The rest I would put into suspention, cage, and tires.

Bob used to take FTD in CalClub. Talked to him said he needed bigger tires (13=>15) and and engine freshening to continue to do well. More exhaust smoke than needed. + more new tires each season. Still a darn nice car and top 3 national CSP finisher last time we talked???
