Hey guys I am really new to this I have a 2003 gts eclipse I just put rims on it and The previous owner cut the springs .So any bump I hit sounds and fells really dramatic. What should i do cause I like the car how it looks dropped. Also what is the easiest way but correct way to get more horse power in my car just to make it quicker. My gts is really mint and I get a lot of remarks on how nice it looks I will take some pictures and put it in the garage here .I have to say this site is really awesome.Please help guys with these questions about the springs and how to make it faster the correct way.

If you like the lowered look, just get lowering springs. Cutting springs to lower the car is a big no-no.

For making your car quicker, check out this posting, it has all the info you need.

well it sounds most likely that you have blown shocks. granted your suspension will be stiff when you lower your car, but when hitting a bump you will still get a decent spring back and the sound won't be very harsh unless the shock absorber is shot. cutting suspension springs is insane unless it was done by a professional racing car mechanic or racing suspension shop.

you don't want to rely on modified springs that might be seated incorrectly. you could hit a pot hole at high speed on accident causing the incorrectly seated springs to pop out. bottoming out one shock completely. you could end up hitting your brakes and only having a 2 wheels worth of stopping power. could be very bad in any situation.

i suggest you change your springs out A.S.A.P. coil over springs aren't that expensive as long as you buy some name brand coil overs off of e-bay you will be fine. also buy some lowered shock absorbers i can offer a brand, but i don't know much about lowered shocks. i hear Ebaich are pretty bad @$$. remember when looking for inexpensive items any e-bay or e-bay like auction site will be just fine as long as its a name brand type just remember to look out for the e-bay or e-bay like brands only offered on those auction sites as they tend to be the same cheap made material with a sticker or etching slapped on it.

any HP gaining mod done correctly will be a name brand modification. i suggest you buy an intake it doesn't really matter short ram or cold air, its all in your own preference. there is a way to make a short ram into a cold air intake. if you get a hood with a real hood scoop that sits on top of the ram air it pulls in cold air once you start driving, Bomz i find to be the most inexpensive online. then get a full exhaust: short pipe headers, and cat-back with a high flow muffler. probably megan or magnaflow for inexpensive, if you want loud, go with a full Injen exhaust, but that will be a lot more than a megan or magnaflow.

after that your looking at engine mods which are a lot of work so not very easy. but you can always upgrade your spark plugs and spark plug wires. upgrade to a high output distributor. also a DSM high output ignition coil will help prevent misfiring, i.e. loss of power just after shifting. tossing in a short throw shifter will help with shifting times. that is if you have a manual transmission.

d-screening your mass airflow sensor will add a little extra HP maybe 2-3 but if you do you have to disconnect your battery for 15 minutes d-screen your MAF reconnect your battery turn your car on and let it idle for 15 minutes before you drive it. that will reset your computer to read your new air flow at what it gets if you had a performance MAF.

other than that its pretty much 225 fuel pump 550 injectors, a new high pressure fuel rail. then your looking at a rebuild of your engine. then getting a racing transmission and racing trans axles. then twin turbos for your V6 and a Stand alone fuel management system most likely a Apexi AFC neo system.

KYB AGX or KYB GR-2 matched up with Intrax Springs will give you the most comfortable ride on a 2" lowered look. I don't suggest coilovers. True coilovers are 1k+ and are best for track use.

The GTS is very high compression (10:1), so stick with basic bolt-on's. Feel free to visit www.sc-customs.com for some ideas on what we can offer and do.

I have a 03 GTS as a promo car. :)

Hey like I said I am new to this and already a big fan thanks for the reply and this car is absolutely awesome. I want to thank you guys for your replys and I wil definately look to fix my suspension problems first cause it really sounds like I can mess up my car and that would kill me with seeing the potential these cars have.I mean WOW i look at some of these pictures and I got to say great imaginations. Let me ask you this are these good cars to modify and do they have good potential for performance or is there not that much one can do. I got to say however it looks like I am going to give it a try and you guys will be hearing from me again. Do you guys know of good car shows I am from chicago but would drive to go see some nice Mitsubishi's just to get more ideas.One more question changing oil in car what do you suggest synthetics and I only put premium gas in my car ?

May 10-11 is Carlisle Performance and Sound at the Carlisle Fairgrounds in PA. It's in western PA so not to far of a hike for you. There are approximately 20-30 Mitsubishi's that I know of that will be going from MITSUOAMA.com

My vehicle will be on display indoors, so you are more than welcome to check that out too. It's a very LARGE event and the best way to expose yourself to the industry, products, cars, ideas, etc.

Thanks I will definately check my schedule cause it sounds like something that I would be interested in. I checked that website you gave me. I was really excpecting some high prices on some of the stuff on that site but i was wrong .You definately got me excited about some of the stuff that can be put in my car. I keep finding your replys all over this site sounds like your really knowledgable to this and i hope to hear from you again on visual and performance upgrades. I wanted to kow If you can answer my question as far as that oil and gas and the car in general .Is it a good car and it already sounds like it has allot of potential but just wanted to hear from someone that knows.

Hey bulletbike this attchment you sent that is definately some good info thanks

You have a GTS, and high octane gas is recommended because of the high compression (10:1) in the vehicle. You CAN run less, however - it's not recommended.

Just do whatever is recommended per the manual and manufacturer for oil. I believe that's 10W30 or 10W40, regular or synthetic blend, doesn't really matter assuming you change your oil on a regular basis.

Carlisle P&S is a must. Go to it. You will learn and a lot and have a chance to see different things on different cars, or in this case, you can look at my vehicle which will be on display and I have every item refinished or modified on the vehicle as a product presentation.

Thanks again I have really got to get my car fixed remember the springs i told you about. They cut them so I was looking online and I saw some I think there called coilovers what do you reccomend should I get those lowering springs and shocks cause I skid on every little bump and If you have a recommendation I would like to hear it and about what a good price is I would likt to do It asap so please help.

yeah man, when i first got to this forum i had some serious learning to do about modifying too. i put in everything i have learned about in that post. now about the springs. some people will suggest against coilovers, and some will support them. coilovers however do not offer a very smooth ride as you mentioned you want to get away from. unless you match coilovers with some great adjustable shocks i wouldn't recommend you get them. i do not know that much about shocks so i would wait until SC posts about the ones he would recommend, even though he will suggest against coilovers i however think its really about what you want. coilovers are often adjustable and lowering springs are often not, unless you pay for that option which comes generally high.

keep in mind that any suspension can ride smooth as long as you match your spring height with your shock height. now when hitting a large pot hole it is more likely to bottom out your suspension on a lowered vehicle, but the natural road conditions like: pavement patches, hilly areas, and train tracks. your suspension will feel soft and smooth as long as you buy the types that are meant for that. now with performance suspension you naturally feel each bump, crack, and road pebble so you can adjust according for best road conditions to help with your tire grip. i had 94 ford escort GT with lowered shocks and coilovers. the car sat exactly 3 1/4 inches off the road from anywhere on the closest part of the car.

i had the e-bay tower strut bars and a custom anti sway bar also, it was a horrible ride, but with that setup i could feel if my car was starting to slip before i got out of control. and i could out race cars with 100 HP or more than me on a twisty turning road any day. you give up comfort for performance a lot of the time when looking for race applications. if your looking for comfort i suggest you get the correct lowering springs and match them with lowering shocks and you should be just fine.

O.k thanks for the advice so S.C if your out there I am ready to but it is very important that I do this A.S.A.P so what do you suggest the lowering springs I have had people tell me I should be fine with just the springs since the reason my car is driving so bad is just cut they cut my springs .

If your car has not been running a full synthetic in it previously than switching to a full synthetic can sometimes be harmful and cause you to start burning oil pretty badly. The best option to go with is a synthetic blend oil. Valvoline and Castrol GTX are the only ones I use in my GS.

what a asshat response, if you switch from a conventional oil to a synthetic and you start having issues of burning oil, i suggest you rebuild you engine because you have some serious issues to fix. "oh lets just let our engine have seal problems as long as you use thick conventional oil or a synthetic blend your engine will be fine until it blows up!!! "

if your engine gets a seal problem from switching to synthetic it still has the problem when you use blends or a conventional oil. seal issues are not seemingly harmless even if you believe it or not. it only takes a little seal problem to make a generally easy fix turn into a complete motor rebuild. playing it safe with a synthetic blend? are you kidding me?

a seal problem is a seal problem. thats like when people put in thicker gear oil in their transmissions to fix a transmission shifting problem that only required you to switch your fluid and filter. instead we will go ahead and put in the wrong gear oil and then next we will take a sledge hammer to our trans axles to try and straighten them out because they are bent......

Hey how are you! I went to buy some lowering springs this weekend and I ran into a situation do I have struts in my car? I really want this fixed correctly. If I would replace everything would I need struts shocks and springs. I just do not want to pay somebody for putting springs then the car still not driving good and then having to pay him for going back and putting in struts or shocks I am trying to learn all this on the fly cause I am better honestly with older cars and I really want to learn to do stuff myself it just fells more gratifying.

The proper way to make the switch to synthetic is to use blend for 2 oil changes then the switch to full synthetic will be fine.

Make sure you have Noooo leaks at all the smallest hole may squirt more than the little you see before the switch.

Hey I wanted to ask with all those modifications that short ram intake or the cold air intake and the full exhaust and the short pipe headers and that cat back exhaust and the d screening of my mass airflow sensor about how much horsepwer extra will that give me honestly.By the way how you guys doin?

All that MIGHT yield 15-20HP.

Your car has factory struts and cut factory springs. The struts are designed to ride at the normal OEM height. By reducing that, more strain is applied to the struts causing them to wear faster and eventually blow out. THe PROPOER way to lower this vehicle is replacing out the struts at the same time as you install true lowering springs. The more expensive option is moving into a true coilover, which I don't recommend on a daily driven car.

I was reading and heard that Long pipe headers would by itself give me 30 to 40 horses is that wrong.
