Just a quick question, and apologies if it's outta place, or unnecessary; I couldn't find my answer with search. However, does anyone know the fastest you can get an FC NA, and what would be needed? My car's pretty gutted out of internals, probably gonna replace the glass with plastics eventually, exhaust and intake is done, so I think I'm about a quarter-way there, but I could be wrong. Only reason I ask is because I have a friend with a Trans Am, and I at least wanna know if it's possible to stand a chance without going turbo.

In the quarter mile? Autocross? All-out top speed? What year/condition/mods for the Trans Am?



Either way, the answer depends on a lot of things, not the least of which is driver skill.

talking quarters for now (though I kinda hate 1/4 mile runs; then again my last car was a 3000GT SL) she's currently running high 11s in her TA, don't remember all the mods, but I know she got a 75 shot of nitrous that she has yet to try out.

Your NA doesn't stand a chance. No matter what you do she will beat you in a 1/4 mile. It's cheaper to buy a turbo RX-7 and make that faster then build up your NA to do a 11 sec 1/4 mile. If it is a newer car she would beat you in an auto-x unless you upgraded your suspension and driver skill plays a lot too.

disagree big time with this negative nacy statment. my 89 gxl full interior stock 90k motor rx7 with a stero system and a 100 shot ran 12s in the 1/4. there was only a rb header hks 60mm cat back and rb sylencer and and hks megaflow and a jacobs hot box. and asfar as suspention it wouldnt take that much for a second gen to make a TA look stupid on an auto x cone killing track. TA and Camaros are slush boxes and stock handle for **** and really are not that quick stock in a 1/4 either. so all you would have to do is loose alot of weight by taking everything out the car that is not needed, run a little larger secondary injector , a 150 wet shot and put some sticky tires on it and that car would be low 12s high 11s. a turbo full interior 90 turbo 2 with 433 whp i did some work on ran 11.2 at 133 all day long every day it went and that was almost a 2800 pound car with a stock gear box and diff wich was a 4.10. now go and get a 4.88 or a 5.13 diff loose the weight in the car wich a second gen can get down to 2100 pounds very very easly with a 125 to 150 wet shot and proper tuning n i bet easy that will be a high 11s car.

Yeah I'm pushing about 160-180hp (estimate) right now, so a few more mods and it should be solid for at least decent quarter times. Also donhayes, I'm staying NA because I'm not particularly a fan of turbocharged engines, not that turbo has any issues, but it's just not really my style. I waited a long time to come across a 13B and I'm not gonna throw that patience out of the window just so I can take the quick and easy way. Whipping muscle *** is more entertaining when you're running natural, and seeing as most of my interior's getting torn out anyway, I might actually be able to shave this thing to a good 2200lbs or less. P:W is where it's at in the japanese market in my experience, and the P is okay for now, so I might as well work the natural advantages of the RX-7 (higher rpms, overall balance) to ****** a win rather than throwing new engines in.

If this is a WS6 hang it up, these cars with basic bolt-ons, on a tire & a decent shot of nitrous will put up good times in the 1/4. Not saying that the NA FC can't put down good times but the car will start to get unstreetable when in the range to beat the WS6 still in modified street trim.

i beg to differ on that, you can with enuff money and the right set up beat a TA with an fc na easy and still be very streetable and leagle.
