Hey Everyone,
I bought a 93' LS ATX just last month. The closet thing I did to modding was gettin some 9004 Silverstars.

Now I'm ready for performance mods.
Where should I start?

1) I had an airtake in mind...what is the best to get, which should I choose from?

2) Muffler. I was thinking about a dual tip muffler. So what should I choose from?

Anything else I should do while trying to make these changes?

Newbie..I hope to learn this car inside out.
My cars got 115k miles how much longer do I have on it? I hope to have it as long as possible.

Thx MX-ers !

As far as intakes are considered, your choices are limited. This is because the LS ATX is so crammed under the hood only a couple companies have made a TRUE cold-air intake (one that draws air from outside the engine bay). www.rr-racing.com has the only true cold air intake I've seen for the ATX LS, but it's expensive. stay away from warm-air intakes or "cold air" or "short air" or "ram air" intakes that are just a foot or two long chrome pipe with a filter. These units do no more than just buying a nice heat-shield cone filter and putting that on your stock intake. I would recommend that because you save some money and time by just getting the cone filter instead of Weapon-R or brands like that.

For the muffler, I would recommend what alot of people from this site, including myself, have done. Look online for a muffler that appeals to you. For this, either contact the dealers or check ebay for a brand name muffler. Then go to a muffler specialist shop, and have them put together the rest of the exhaust system. Just buying a muffler will most likely end up making a raspy buzzing noise instead of a deep sporty sound like most guys look for. I cannot stress this enough. Stay away from just the muffler because it will sound like crap and probably look about that bad as well, and on top of it won't really add any performance over a full cat-back. I got my muffler for 80 and my high flow cat for 90 and had the shop put everything together and my final price was like 380 or something, which I think is less than what most companies charge for just the full cat-back exhaust system with shipping.

As far as other performance, just the catalytic converter is a good idea. Plus, new spark plugs/wires, and make sure that the piping you get for the full cat-back is 2.25" or 2.5" which makes it larger and less restrictive than stock to really free up the extra horses. And if you care about more than just going in a straight line, a strut tower bar/brace for the front and rear is a good idea too. Can be had through ebay for pretty cheap I know for sure and it'll make a noticeable difference. I hope this helps! And if you're interested in some direct-fit Supra style tails, check www.mx6performance.com or just PM me. Welcome to the website man!

with only 115k miles, as long as you keep up on regular maintnance and do occasional repairs youre engine will last you forever. the main parts to worry about on your car are the timing belt tesioner, rear brake calipers, auto trans, and distributor. there nothing u can do to lessen wear on most of them but for the auto trans you can get an auxilary transmision fluid cooler, and just make sure your to a complete stop before putting it into gear, try not to put any extra stress on it than you already do driving.

Sup miami? Welcome.

CAI, Zoom Zoom is right, RR-Racing(~$195) is the only place I know of to get a TRUE CAI for the LS ATX. The Weapon-R Dragon setup is a warm air intake, and a bit pricey for that($81.00), but it is a foam filter not steel braid like most others, and if you buy it from RSWerks they are giving away a free heat shield w/ it...There is a thread(search for weapon-r or dragon intakes maybe) where someone had this setup hooked to the stock air ram above the radiator, this set-up looks fine to me, safer for areas where there is alot of rain, snow, etc...

Exhaust... I have a Borla, it was really cheap($75) from a local parts store and sounds really deep and throaty, I get mad compliments on it. If you are worried about performance you might be disappointed after installing a hi-flow exhaust as you will lose alot of low-end torque. Also, a hi-flow cat is not gonna make a huge difference anyway, but with both you will definatley lose ALOT of low-end power... You may wanna wait until after you have installed AT LEAST a CAI to do this.

Transmission...Definately buy a trans cooler, check out B&M Coolers, at the bottom of the page, look at 130-70255 and 130-70268, these are the best(most efficient) design and size.

Also do a search for IAT Mod, this involves placing a switch inline with the IAT which can disable the "luxury shift" system to give you much harder up-shifts. This mod costs the price of a switch and works very well, but you will definately want a trans cooler added b4 you use this too much as it will heat up your tranny pretty good.

Check out some poly-urethane motor mounts at RR-Racing, these will let you put more of your power to the wheels and are quite effective, the set for front and rear will cost ~$55.

ProCarParts is a good place to find the rear strut tower brace, get the front one from Here, Bomz are just phat.

Hope this helps!

Modding comin' in to effect

You guys really are helpful.

My buddy knows some pretty good help. Man the labor is alot, so getting some friends to help out with putting it together would help.

Another thing I wanna know is I read about how the 93' had alot of outside resonance. This problem was taken care of in the94" what can I do to keep unwnated noise out. Is this the same issue as air/wind noise. When I drive at higher speeds onthe highway I get air/windy noises.

Thanks guys.
