Hey guys, I'm new to the perfomance modifications game so pardon me if these are silly questions. I have a '98 Cobra droptop with A K&N, and a new X pipe and a Borla. What I think I should do next is a larger throttle body and MAF sensor, but I don't know if I would need to do anything else to upgrade fuel delivery to avoid running lean. Also I don't know if my stock gears are 3.08's or 3.22's, but I am going to upgrade to 3.55's or 3.73's. How much of a difference is there between these (in terms of RPM during highway driving)?

 

Dude, first and foremost... get gears... 4.30's no doubt, anything less and you wouldn't be a man

 

It's a daily driver...I gotta be a little more practical...

 

you could do 4:10's i have them and my 97 is a daily driver i still get about 300 miles per tank somtimes more or less depending on how hard i drive it.

 

What about the TB and MAF sensor?

 

I THINKTHOSE WOULD BE GOOD MODS BUT YOU WILL NOTICE A BIGGER DEFFERENCE WITH THE GEAR
