00 Eclipse GT vs 99 GSX

So my buddy just bought a 99 GSX. He's been wanting to get a car for a while and he finally got one so he can cruise around with me in my 2000 fed spec eclipse GT.

Thursday night after work we decided to get a fun run in on the highway. We pace each other at 60 mph. My buddy counts us down: 3, 2, 1, GO! I downshift into third and punch it and he gets the jump ahead by a quarter car since he was already in third. I reel him in and pull about a half to three quarters of a car by 100 mph where where I was still pulling before we shut down.

My car: 2000 Fed Spec GT, AEM short ram intake, GReddy Evo 2 catback, B&M Short shifter.

His car: 1999 GSX bone stock

Now all we have to do is go from a dig where I expect to lose to the awd launch.

And yes I realize that once he starts modding I will be getting a nice view of his bumper :rofl: .

Good run...everyone talks about the 3G V6 eclipses like they are shit, but this just proves them wrong...in actuality they are much NICER cars, I've driven a 2003 GT-S convertible.

Yeah very nice looken cars, pretty quick too. When i was looking for cars before the Srt-4, I was considering Se-r Spec-V, VW GTI VR6, and an Eclipse GTS. GTS is a very nice car all leather, pretty quick too. Low 15 sec car.

Interesting results, not the norm

good luck with that turbo project I see in your sig...At the stop I ran into a guy getting a similiar install in his 3g.....seemed like it was going to be quick as shit!

^^^ thanks. I'm very excited about getting this turbo project done. My grandmother said she would front me about 3500-4000 to get it done before summer and I can pay it back interest free. So hopefully if I can find a good shop around here I'm hoping to have it finished in a month or so. I should be looking at around 350 to the wheels so people will have to watch out for this 3G

thats nice. i raced my friends eclipse gs-t with my uncles 01 eclipse gt and i won.

and? I read the "2g, 3g, which to buy" thread and I'm not sure what your point is to my reading that. If you want me to say that a 2G turbo whether a GST or GSX has a lot more potential and is easier to mod for cheaper than a 3G; well duh I already know that.

I'm not really sure what your point is so please elaborate for me.

That was my point exactly ass. No really I was looking at your turbo project. JUST make sure you tune your car right because I've read and seen lots of stories of motor failre on un-properly tuned 2000 plus eclipse gt's. Now the rs/gs's those are different.

my point was make sure you read about what other people said before you turbo your car. Not 2g cars being easy to tune because we already know that.

hows that short shifter? i know the stock pieces in majority of the new mitsu's feel like total crap.

Drew: Wasn't trying to be an ass, just trying to get some clarification. You quote me on my race and the point of your post is about my turbo project. Just some confusion is all, it was like 1:30 in the morning when I read that anyway.

I appreciate your concern on me not blowing my motor that's why I've done A LOT of research on how to turbo my car to make it safe. Trust me I'm the last person who wants to blow up an engine. I've been reading the tech forums over at club3g damn near everyday for the past seven months while I have been saving up money for my project. I have also been reading Maximum Boost by Corky Bell to learn some good theories behind turbocharging and how to keep it safe for the engine.


CivicHB: I love my short shifter. Really short throws and they're nice and crisp. It is a little notchy sometimes but I dont mind it.

i heard thats a great book. i will be buying it soon

Good luck with that, 350 WHP is a pretty lofty goal.

not very unreasonable though. there is a GT in florida running 8psi with 328whp. not too shabby

Good luck with that, 350 WHP is a pretty lofty goal.

I'm confident that I will hit around that number. I just have to find a tuner near by that knows what the hell he's doing. I'm aiming for around 350 but hell, nobody's ever been dissapointed with over 300 to the wheels so as long as i'm over 300 I'll be happy. It'll be exciting to see the outcome.

well just beware about goin 300whp and over on a FWD with no LSD. you will lose to almost every car from a stop becasue you'll just be spinning. however on the highway you can wrip almost anything to shreds.

TatII, I've thought about that. So I'll be going with a quaife lsd to get some more power to the ground without just making smoke. It'll also make the twisties more fun. I'll also have to get some new sticky tires causea the stock Eagle RS-A 's suck ass.

well the LSD makes it more bareable. however its still not much off the line without slicks or drag radials.

350whp?? Damn! What do they have stock?

2000 eclipse gt's have 205 stock since they're fed spec. so about 175-180ish to the wheels stock.

well the LSD makes it more bareable. however its still not much off the line without slicks or drag radials.

Traction is the crutch of a high powered FWD car. I'll be fighting with traction the whole way. It doesn't really bother me though because I dont usually race from a dig anyway. The thing I like about the LSD is that it reduces torque steer which is a big problem for FWD cars. The LSD won't completely get rid of torque steer but it will make it a lot more bearable. I dont want to get my turbo installed and not be able to drive it to its full potential because everytime I get on it and shift to the next gear and punch it the damn steering wheel gets ripped from my hands.

So you plan on running like 17psi+ on stock internals? I'd say 250whp would be a more reasonable goal...

not very unreasonable though. there is a GT in florida running 8psi with 328whp. not too shabby


I will be running .7 bar which will be 10.15 psi so I think I'll be able to hit my goal relatively easy with some good tuning. 17 psi from a turbo on stock internals would blow the hell out this engine. I've heard from a guy on another forum that builds engines, specifically the 6g72, and says that the internals can handle around 12 psi on a REALLY good tune but that's pushing it. So I'm gonna run 10 psi. to stay safe.

So you plan on running like 17psi+ on stock internals? I'd say 250whp would be a more reasonable goal...


There are people that have hit a little over 250 whp on the v6 running at 5.8 psi.

I'm looking at around 380rwhp@8psi. And 8psi is pushing it on my stock internals. I know they're two totally different engines..but is your engine THAT much stronger than mine?

I honestly dont know. I know nothing about mustangs or their engines other than their stock horsepower. I do know the faults of my engine and the reasons we can't boost past a certain psi or shit starts to break. It could also be the different methods of FI we are using. You're going with a supercharger correct? It might have something to do with that or it might not. Like I said I'm not totally sure.

Pressure is pressure. Doesn't really matter if it's from a supercharger, turbocharger, or nitrous.

Pressure is pressure. Doesn't really matter if it's from a supercharger, turbocharger, or nitrous.

Pressure is pressure but volume of air has to also be taken into account. I am runnen 15 psi out of my stock turbo, but it is so tiny that 15 psi is almost nothing. with 10-11 psi out of a larger turbo on my car and your gunna have alot more hp then the 15 psi.

Damp you'll be goen from 260 to 380 thats 120 hp increase at 5.8psi i think u said?

My stock block is roughy 130 hp with turbo its 230 at 15 psi so thats roughly 100 hp gain with more psi.

Now i can be completely wrong here and someone will totally own me. so i r prepaired.

More like 230rwhp to 380rwhp@8psi. 260 is at the crank. And if its 130hp stock...at 15 psi it should be like..260ish.

Hmm mb i have this all wrong, am i wrong that PSI doesn't matter as much as volume of air? Some one needs to give me a quick lesson on forced induction.

I'm confident that I will hit around that number. I just have to find a tuner near by that knows what the hell he's doing. I'm aiming for around 350 but hell, nobody's ever been dissapointed with over 300 to the wheels so as long as i'm over 300 I'll be happy. It'll be exciting to see the outcome.

Yeah, it is very important to find a good tuner. Your big problem is the lack of aftermarket for the 3rd gens. I'm not saying that 350 WHP is unreasonable, just lofty.

Keep us updated on it. :)

I'll most definitely keep everyone updated on when I get it finished and I'll have power numbers as well. I'm looking to have it totally finished before summer.

Yes, the guys in the DSM forum explained this to me...volume of air being shoved into the engine is a lot more indicitave of power than PSI...for example...a 16g running at 11 psi will put out a HELL of a lot more power than a T-25 running at 15 psi, because the 16g is a much bigger turbo and moves a lot more air.

you are correct sir.

my turbo knowledge=teh win...j/k

DSM turbo knowledge=teh win...


fixed :rofl:

Ohh ok thats what i originally thought. Damp had me confused there.

I allways though S/C was the better route to go on 2000+ eclipse GT's. I have seen quite a few kits but they look quite pricey.

nah the turbo made more hp per psi for some reason, its just a little trickier to fit in there, i'd love to have a turbo too, but i don't think that is a good idea until i have absolutely everything else done, brakes, suspension, drivetrain, and supporting mods

Whats the compression ratio on those motors? How well are they going to handle boost? The internals pretty strong?

My friend has a Turboed 2000 GS. T3/T4 set up, real nice and pretty fast. Him and I are neck and neck. He is still untuned, he is hopeing to get tuned this weekend so i might have a good race to post and a video.

The GT CR is 9:1
GTS CR is 10:1
not sure about the four cylinders.

thats a nice comp ration on the GTS btw.

but I have to be the bad guy and ask... besides just doing something new.... why dont you just sell your 3g and go find a 99 gsx with low miles for relatively cheap and mod it lightly? I mean if looks are your bias against it then yeah stay 3g. But speed wise its more cost effeciant to sell your 3g and buy a 2g dsm + mods.

Lets skip the whole whp thing. What do you think you will be doing in the quarter? 99 GSX with 2k or less in mods will do 12's.

Not trying to be an ass but feel it should be said. If your just pro building a 3g v6 turbo more power to ya; just dont want you going down a hard route not knowing easier or most likely faster choices.

I know your not trying to be an ass even though I've heard your argument a BILLION times since I bought my car. I do know where your coming from though. It would be a TON easier just to get a 2G GSX and mod from there. I was actually looking for a 2G turbo when I first started looking for a car but I just missed out on a couple opportunities. Then I came across my 3G and got a great deal that I couldn't pass up. I'd like to get a GSX but it would be too much of a hassle to sell my car and get a good price for it and then try to find a decent GSX with low miles. They're really hard to come by around my area. And I'm gonna love having a 350 whp 3G cause nobody is gonna suspect a thing cause everybody is hating on them.
I'm having a blast modding this car because not a lot of people are doing it so I have a unique car whenever I go out and drive. As for quarter mile times, I'm not really building this car just to see how fast I go down the quarter but I'm expecting to be in the 12's somewhere. A Stage 3 SDS GT pushing a little over 400 whp put down an 11.84 so I think 12's should be a reasonable goal with some good street tires.

Besides, my buddy has a GSX (the one who I raced in the first post) so I'll get to work on that with him so I'll have the best of both worlds.

didn't know the compression ratio was so different, maybe i should look into changing mine to GTS spec, since i have the wheels and all

I dont think that would be very cost effective. You'd have to get new pistons to raise the compression to 10:1. Which means the money for the pistons plus money for a shop to install it. That's a lot of money for less than a ten horsepower gain. The main reason the GTS has ten more horses than the GT is the intake plenum. The GTS has equal length runners as well as dual runners which are rpm activated so the air travels a shorter path to the engine after a certain rpm. So if you want to change over to a GTS setup you should just get the GTS plenum. They're hard to find but can be had for around 300-400 bucks used and can be installed yourself. http://www.club3g.com/forum/showthread.php?t=531 here is a how to on the plenum swap if your interested. It can be done with simple hand tools and a little bit of soldering to extend some of the sensor plugs.

i have full access to a shop and there's a guy in okc parting out a wrecked GTS, so i'll see about nabbing them pistons cuz he already sold the plenum
and maybe i'll grab the ECU too just to be on the safe side

Sounds like a lot of work for such a small gain but hey if you're up for it then more power to you.

I would advise that if you plan on going FI in the future that you stick with your stock pistons or get forged pistons with an even lower CR of around 8.8:1 as they are more suited for FI.

i'm still in the debating phase of going with FI and having downtime on my car (large amounts of downtime) or going w/ an old-school eclipse GS turbo since i know people that know them inside and out and i'm more familiar with them too, that and they put out better numbers than highly modified 3g's, or a 240 turbo, or a 300zxTT or finding another GVR4, so i'm a little lost on where i want to go with things

thanks for polite post back. good luck on building up the 3g turbo. keep us posted!

all of the cars you mentioned are great choices for a project. 1g DSM turbos are pretty badass and have a huge aftermarket for them as you most likely already know. An SR20DET in a 240 or even a turbo KA24 240 would be badass as well. Good luck with your future project and have lots of fun.

thanks, i do know that repair times on 300's are killer though so i prolly won't do that

thanks for polite post back. good luck on building up the 3g turbo. keep us posted!


No problem man. I'll most definitely keep everyone posted on my project.

Excelent, i love hearing about other peeps maken thier cars faster. Def keep us updated i wanna see how that v6 in there takes a turbo. You goen single or twin turbo? are the 2 exhaust manifolds just gunna join down to 1 for a single turbo?

its going to be a single turbo. a pipe is going to come off of each header and merge via a y pipe and then go up to the exhaust side of the turbo. Then I'm gonna get the shop to make me a 3" downpipe through a 3" high flow cat and out a 3" Greddy evo2 catback made for a GST.

Do you have the parts you need for the turbo yet? if not what do u still need, if you do whats stoppen yah?

right now I have everything I need except the injectors, gauges, LSD, Cat, and Catback.

Technically I dont even "need" the lsd, cat, and catback but I figure I'll do it right from the start and get the 3" from the turbo back and go with the lsd for traction. Plus I'm hoping they'll cut me a break on installation since i'm gonna be having everything installed at the same time instead of getting things installed one at a time. Especially the tranny stuff like lsd, clutch and flywheel so they only have to drop the tranny once.

Right now money is the only thing stopping me but as I said in an earlier post my grandmother is gonna help me out with a loan so I can get my turbo done before summer. Thanks Granny :lol:

Awsome man can't wait tell its done.

me either

When you complete your set up we should race. My srt-4 VS your turbo GT from a dig.



















In reverse

lol sounds good.

what shop is doing all your work?
