Finally got the intake and exhaust so what next???

[Wilfus65gs]

I finally got my intake (k&n filter with stock pipe) and my exhaust (custom piping from cat back with magnaflow muffler) and i was wondering what i should do next. I was thinking either a computer upgrade or underdrive pulleys but i dont know which ones are good. Any help or other suggestions would be great.

i would say:
replace the cat with a hi-flow or straight pipe
get a header
underdrive pullies
bigger throttle body

It is an underdrive pulley.

But yes 1) Get a Hi-Flow Cat 2) Get a header 3)af/x UDP 4) get a wideband o2 sensor and a a/f guage b/c after those mods i was running rich so i decided an afc was needed 4) Jusst port your own tb to 55mm then you will start heading into some serious modding ie p&p intake manifold, p&p your head, cam gears, cams etc etc. Maybe nitrous , internals etc etc.

There is a tuning guide on this site, i think u might find it helpful

EDIT: whoops the guy before me was nice enough to get a link, than ks

Dollar for dollar, the one BPU you will notice the most will be the UDP. It's $140 or so from Howell Automotive. I'd suggest getting that first. After that, look into a nice header. Check the sale/wanted forums and maybe pick up a used one for cheap. I got my mint condition Pacesetter 4-2-1 for $60 from a guy going turbo. After that, start thinking about what your goals are for the car and go from there.

it doesnt matter so much how many miles are on your car as it does what condition your engine is in. if its in great condition, and your compression is good, then you should be fine. if the engine is beaten to death, you might have some problems...

now with that said, you can supposedly use a 75 shot on our engines. i am not that brave so i thought i would just play it safe with a 55 shot. well the first day of having it i craved a little more so i bumped it up to a 65 shot. i dunno if im gonna kick it up to a 75 or not. but nitrous doesnt ruin engines, its improper use that ruins engines. use it right, and use it safe, and you should have some fun.

hmmm.... if nitrous is like sex, i wonder what it is like to do both at the same time. That would be interesting...
