i have a 94 z28 auto with 102000 miles on it and its 100 percent stock and i want to run a 12 sec and i wanted some opinions on wut mods to do money is not important cus im doing it slow. thenks

 

Cold air intake, headers, catback, Tq converter, gears and tune. That should get you close depending on what your baseline is. After that you need to chose between spray or a cam. You can also reduce weight, but it takes about 100lbs to equal a tenth. get some timeslips and let us know where you stand in stock form.

 

what gears do u think are good for me and converter to i dont know much bout them its my first auto

 

Overall the best gears for you would be 3.73's. If you was going strip only, then im sure a much lower gear would be better.

 

you can also go with bolt ons such as a throttle body, under drive pullies lil things like that. I'd recomend a 3200-3600 Circle D converter.

 

...and don't forget the Drag Radials!

 

the car is not a daily driver its mostly a project

 

drag radials, full exhaust, and a stall. If that doesn't get you there a cam will.

 

what times should i see before any mods 100% stock

 

Down here in south texas we hit high 13's to low 14's on lt1's 100% bone stock.

 

14.4~ is what I ran in ohio.

 

Stall, drs, LT headers, cat back, CAI, Electric water pump, 1.6NSA roller rockers and a mail order tune should put you into the 12s; if the motor is running good.

 

13.80s @ 100 bone stock 94 Formula A4

 

In my opinion, the best way would be in this order
3.73 gears 3000+ stall, drag radials, cold air, long tubes+ exhaust, torque arm+lower control arms, sub-frame connectors, remove front sway bar, remove all the crap
dont forget the tune

Ive run 12.80 at 108 with a less than 60 hp shot of nitrous
on street tires.
I'm thinking when I get my new trans and stall Ill be in the 12s with drag radials

 

With just a K&N CAI, I ran a 14.1. That was my first time in my 80,000 mile Z28. I know it would run 13.9 if I had a better reaction time.
