I have a 97 G.P s.e with 3.8l and have no mods done yet, can someone give me advice on upgrades that I can do myself (fairly mechanically inclined) starters tip would be great!

mufflers and tips would be good starters???? you need to give us some mroe info so we know were you wanna go with this car and how much modding you ewant to do

A CAI would be good. Also, since you're doing some exhaust, get the Ubend deleted.

Basically I would like to get around 250-275hp
if possible without getting internal,would like
to get to spend more time on cosmetics.

buy a turbo, but make sure you upgrade your tranny.

Well im not much for all-show-no-go cars myself, without getting internal your not gonna get many extra ponies since alot of the best mods for GPs only reach their potential when used with other mods that benefit each other.

I would suggest getting better intake before you put muffs etc on, but you gotta do your research and plan out where you want to go with your mods before you start to avoid wasting time and money.

Without adding forced induction you are not going to get those kind of #'s without going to internals (did you mean crank or wheel HP?) to get the 3.8 N/A to near those #'S you will either have to stroke it,or raise comp.ratio add a cam do some head work,larger injectors,bigger throttle body ,headers or PEM's ,all in all to achieve say 275 WHP is going to run around $2500-$3000 whether you stay N/A or add forced induction.I suggest you do some research.

by a gtp and do a ubend delete and get some muffs, you might get 250 out of that

Cosmetics: You mean like Aluminum wing, aero kit, large diameter muffler, uni-wiper e.t.c?
Save your money dude, those things are expensive, pointless and would look tacky on the car.

Besides, there aren't that many companies that sell those items for these cars because GPs are more so sleepers. For an S.E., the furthest you could go are wheel/tire combo and a paint job.

You won't get 250-275 easily with a 200 hp N/A engine. U-bend delete, CAI, throttle body, exhaust, will get you 220 at best.
For that power, yes you need the CSC supercharger or turbo with an upgraded tranny.

www.pfyc.com and www.zzperformance.com are places to start.

Yeah I'm talking about rims & tires front and rear bumpers from a G.T or G.T.P and a fresh paint job plus tinting the windows thats all I want for cosmetics.Your right all that other stuff looks ugly to me to.

Saw a car with 20s. You need to place in an additional offset but they will clear. 30 aspect ratio tires didn't last long though.

Best source for parts? JUNKYARD!!!!!!!!
Great expensive parts for pennies.

Not sure about the 20's anymore thinking about it maybe 17's now undecided that's what I like about the winter in Canada it give's me time to think about it. Just to drive me crazy.LOL!

What do you think of those mini bras I live in a small town and my hood is taking a beating it's just a stock hood for now.Do you think they look cool or what?

18s.
For bras, there was just a thread about them. You can check the archive. Some say causes more damage than they worth.
My vote is yes but use it temporary for stone chips. DO NOT use in winter or rain.

Eh, if you want to redo your body I would suggest the Inferno body kit, its the only kit on GP's I can stand to look at. Our cars are sleepers get some work under the hood and once you crush'em on the road your car looks much better to them.
