I have a 91 n/a, streetported, headerback exhaust, airintake, powersteering removed ac removed. Any ideas what 0-60 time and 1/4 time would be?

 

Maybe 0-60 in 6.5 seconds..

 

6.5... jesus christ my n/a is a lot faster than that... and it's on stock ports

 

Could be anywhere from 5 seconds to 13 seconds. 5 seconds being the car is stripped completely with higher gear ratios and a good driver. 8-9 seconds for a close to factory wieght, bad tuning and a mediocre driver. 13 seconds if the motor is nearly dead and you have an auto.

 

So your N/A is faster than a TII on its stock ports? Please don't tell me you counted 1 mississippi 2 mississippi while watching the needle. And if its alot faster you're probably beating WRX's, S2000's, and 350z's.

 

mines not stripped... has a little weight redux, stock ports, stock tranny, good driver, and im under 6.5... so wtf? on an s4 n/a

 

no, i didnt count, lol, had a friend with a stop watch, which isnt really that accurate... but it wasnt 6.5... only thing different with the drive train is a newer tranny, mazdatrix shifter, t2 rear end

 

A 6.5 0-60 is approximately 15.0 1/4 mile at sea level. On an N/A with stock port this IS possible depending on degree of weight reduction and mods. I hit 14.9 1/4 mile on stock port, but it took some work.

 

all of my weight redux went to crap, because i had a friend in the car with me... it all started when i kept beating everyone in first and second... which is 0 - 60... so we had to test it out against a few cars, and eventually a few times with a stop watch

 

but that was with the old SE tranny and open differential.. so who knows what would be different know with the newer stock tranny and TII rear end?

 

oh yeah I forgot the engine, is just rebuilt, 8,000 miles on it, it got everything replaced and the transmission was just rebuilt as well. the gear ratios were a little changed I believe. Because I got up to 88 in 2nd at 8,000rpm and 110 in 3rd at 7000rpm and 8,000 is redline.

 

i would say 14.2-14.8 if you can drive

 

any idea about a 0-60 time?

 

15.4. Sounds like whoever did your tranny killed your acceleration. Adding 20mph to second gear is pretty damn excessive.

 

I'd say 20mins 0-60

 

actually it accelerates very quickly, it goes 110 at redline not 7,000rpm** my fault, and that is only adding about 10mph as far as im concerned. n/a goes faster top end, less compression.

 

just go get a g-tech, their like $199 and they show you everything you want to know

 

with my old gtech i consistantly ran between 6.3 and 6.5 on several runs on a cool night with my 91 n/a (A options package), with a slipping clutch and bad throwout bearing. my car had a bonez racepipe, 2.5 inch catback with straight through mufflers, intake, msd ignition and no spare/jack and a few other needless items taken out. this was at sea level. it had a high milage engine but excellent compression. the car was in great mechanical condition and i would launch anywhere between 5.5 and 6.5k with good tires. although it was only a n/a it was pretty quick and could surprise quite a few ricers. died of pd failure/fire so until i finish rebuilding it im stuck with a 91 vert...auto

 

Doesn't matter how 'fast' it 'seems' to accelerate, by making 2nd hit 80 is going to slow it down from what it original was. Regardless, I still don't see much evidence that would get this car below 15's.
