Help me, need answers!

I just bought a 2001 3G GS. I've already put in a cold air intake and I need more. Here's where I need help. I have complete access to a mill and all the other stuff to machining work, I just don't know what to machine. I heard someone talking about boring out the throttle body and still like that. Also, in another forum, some guys were talking about adjusting your maf screw, can someone clarify on how to do this. Thanks

how bout putting an exhaust on so the car can breathe, or your intake is near useless..

That's next week, I'm going magnaflow, but only the muffler. Everyone seems to think the cats and piping are just as good as aftermarket. After that I think I'm going direct port nitrous. But I'm wondering what I can do now, especially considering I have access to a digital mill. Also I'm wondering about that maf sensor. Today I took off the heat shield off of my stock exhaust manifold, and cleaned off the headers, then reset the ecu. Seemed like it gave it a serious power gain. After that I actually took a 5.0 in the first 3 gears.

no way in hell is a muffler as good as a full exhaust, whoever told you that is dumb as fuck and shoot be shot on site.

The stock exhaust on the 3G is really quite good, which is why you only gain 2-4whp by changing it out. the biggest restriction with the exhaust would be the muffler. The biggest reason for getting an exhaust system would be to get quality sound.

For the MAF, you are only able to bore it out by about 3mm which really will not add alot to the power of your car as you are still running off atmoshperic pressure.

For the MAF screw, that adjusts your air/fuel ratios very rudimetarily. I would suggest that you get the GReddy E-manage or another type A/F controller such as the HKS SAFR II. If you want to adjust the screw, it is under the MAF and you will have to remove all the silicone. I would recommend that you get on a dyno and adjust it.

it is in fact similar to a full exhaust if by saying full exhaust u mean cat-back so sit back and read a little before posting, every muffler shop i went to suggested i not take out the stock system just because it was just about as good as it gets when it comes to exhausts, the muffler however, i could do w/o

after you get done w/ that i'd try getting some resonators taken out, i heard a diameter of 1 and 3 quarters inches...the smallest part of the exhaust route thus far
unless you have fed-spec, then muffler is all you need

How bout you don't know what the fuck you are talking about, a muffler is no more then a fucking fart can.

on a honda yes, but on the eclipse the stock design IS AS GOOD AS most aftermarket cat-backs, on the eclipse it isn't a fart can because these cars won't fart like a honda, so instead its just a muffler

How bout you don't know what the fuck you are talking about, a muffler is no more then a fucking fart can.

and thats why you're a newbie and you dont know what the fuck you're talking about

and obviously you don't know shit about your own car

i doubt he drives....:-/

i don't know think anyone on this site has a dam clue wtf they are talking about, where the hell do you get your information from. It is physically IMPOSSIBLE for just a muffler to be as good as a cat back. The bigger the piping the better breathing, so how do you come up with your moronic theories??????

well then....that shows that you don't know shit about your car. if you did, you would know that the stock exhaust piping is just about as good as aftermarket piping. the only difference between the two is the size. the stock size is 2.25''. the Greddy Evo II is 2.5''. thats just a quarter of an inch. it doesnt make that much of a difference. the only part of the whole exhaust system that makes a difference is the muffler. thats where our exhaust is so restrictive. change the muffler and your get ALMOST the same as an aftermarket exhaust system. now where do you get your moronic theories from??????????

The bigger the piping the better breathing

If your piping is too big on an n/a car you'll lose power because you'll lose the vaccum effect that your car uses....

omg I can not believe you are all fighting over this! Obviously those of you who know what you're talking about, know what you're talking about! Those of you who don't (i wont say names *cough*) stop trying to be a big boy. Why don't you just try getting a muffler and if you aren't as impressed, get the rest of the freaking exhaust. There, fighting done!

Hey bitch how bout i already had a muffler put on for months then i switched and had a cat back put on. You guys are dumb as fuck, i told my friends about this website and they laugh their asses off at your comments :loser:

then i guess your friends are as stupid as you are

stupid people have friends?! i thought their friends were invisible....

as for ur thinking we're stupid, every application has different needs to make power, in our case, its only a muffler, on any other car, its a cat-back system

go...learn...become un-stupid

i told my friends about this website and they laugh their asses off at your comments :loser:

Man, I dont know what my life is going to be like now, since you got your Friends to laugh at me. :uhoh: Haha..chill out, it was a joke man. but you are still wrong about the muffler thing...I mean..it is laid out for you 2 1/4 inches to 2 1/2 you gain only 1/4 inch in piping. All they are saying is that, with that it isnt really worth the money and that the muffler would be a better purchase. Youd get more for your buck. Man, im a newbie and i knew that.

:screwy:

honestly...I try to fix a situation and I just get called a bitch? Wow...how impressive...big boy knows how to use profanity!

you know, eclipsesage, this whole forum is meant to be a place to help out those in need...not a place to vent some pent up frustrations...so either accept the fact that we're just trying to help, or dont put in your input if you just plan on starting shit, that's childish and unnecessary on this site

hey mitsugrl, do you have a picture?

of?

haha, YOU!!! i think he wants a pic of u....he might think ur cute...

actually i gained alot more then 1/4 inch in full piping if you knew anything then you'd know that stock GS piping is like 1 1/2. so yes i will laugh at you, thanks.

Honestly, I'll admit I only know as much about DSM tuning as the guys at Buscher let on. My boss's kid is much more in the know about what works and what doesn't.

But I will say this, with a stock turbocharger you're more concerned with optimizing current systems than you are with replacing them. The biggest gains would be from reducing strangling baffles and bends in the exhaust. True performance mufflers, like those from CapTrap, Walker, and Flowmaster, re-engineer baffling systems so that they still allow for free-flowing exhaust. Couple this to a high-flow catalytic converter and a fresh turbo manifold or header and you'll see substantial gains in low end torque and a healthier powerband.

Simply attaching a larger pipe to the factory cat or factory style mufflers will give just about as much gains as bolting a new exhaust tip on. In other words, none at all.

And, by the way Sage, consider this your warning to mellow out and be a bit more receptive to the general population here at AF. We do have profanity and content rules here, after all.

a picture of yourself crazy

*blinks a few times* i'll possibly think about finding one =)

Eclipsesage, the GS does not have a 1.5" exhaust. I am sorry that you think this, as any measurement will tell you that it is 2.25". I have measured it, AAI has measured it, Ripp has measured it, Magnaflow has measured it, etc., etc., etc.

You are wrong in your assumptions and keeping down this path of blindly thinking your right will only turn more members off from you.

well what the crud...I cant find a really recent pic of me but I have one posted from last christmas on my yahoo profile, you can find that by clicking my name on here =)

ok nm I guess that doesnt work...hmm...

put a 1" throttle body spacer on it! i payed about $90 for mine. i noticed a big difference in torque.
