2001 Eclipse GS Turbo?

[brandoninco]

Are there any turbos available for a 2001 Eclipse GS? I read that it has the same engine as the 2nd generation Eclipses, so turbos that would fit those should fit a 2001. Is that true? Im seriously looking into turbos but I need some guidance and some recommendations please.

The 2000+ Eclipses come in a 4 cylinder and a V6, neither of which were used in the previous Eclipses.

There are turbo kits available for both of the new Eclipse engines. Check out www.ddynopower.com for more info on available kits.

Hmm thats funny, my 91 GSX has a 4 cylinder. No they didn't use the same 4 cylinder motor.

Anyways check out Hahn Racecraft or got to www.clug3g.com and ask on there. They probably have reviews on every turbo kit available for 3g's.

The 3G eclipse 2.4l is a 4G64. KNOWING this to turbo it I would suggest SERIOUSLY in investing in a 3G AEM EMS, speed density setup, and all the "bolt on" type turbo parts that the 4g63/64 crowd use for turbos. I have no clue what head is on them but you may have to get a 4G63 DOHC head to use our intake manifolds and what not. There could be other problems involved with it, but honestly I would say to do it RIGHT you're looking at $5,000 to $9,000.

Hahn sells kits to turbo things but IMHO it's a pathetic setup, just ask Patrick.

That's what I meant. Neither of the engines in the 3g Eclipses were used in the previous models. I'm sure he knows that they were all previously 4 cylinders.

Hahn Racecraft does not make turbo kits for the 3g.

According to one of the 3G sites they say the 2.4l 3G is a 4G64. Some of the Evo sites say this as well... It would make sense for Mitsubishi to use the 4G64 in their cars still because they have a ton of the blocks and they're a solid design.

Well I really dont have $5K - $9K to be spending on a turbo. Is that really the only way to go? Surely there has got to be a cheaper route. When I consider what some people pay for CAI's like AEM and whatnot, I find it hard to see just what makes those ones so much better than the one I paid all of $40 for. Dont they, in effect, do the same thing? Provide the engine with cold air so it adds a few horses? Mine is metal also, and seems to be doing just what it should. I dunno, I just have a hard time seeing past that. I appreciate everyone's help. I have looked into the websites that have been provided and got a few more answers. If anyone else can give me some more advise I would appreciate that as well. Thanks!

Ok, I'm going to type REAL slow so you can follow me here. AEM makes other products than cold air intakes.... I said to do a TURBO SETUP (not a turbo) correctly IMHO you should purchase an AEM EMS (ENGINE MANAGEMENT SYSTEM). It would allow you to not use piggy back devices and actually handle fuel and spark curves based on boost levels, which is the way that true factory turbo cars do it. It would also allow you to change your fuel system, which you will HAVE to do. Having said that.... lets follow the pretty bouncing ball shall we?


You will need the following items to make a 4G64 into a turbo....

a COMPATIBLE 4G63 DOHC head.... I do not know what head you have on the "supposed" 4G64 but if it is NOT the same as the DOHC 4G63 head you will need one.

An exhaust manifold which will bolt to above stated head so that you can bolt up a MHI flanged (or garret if you so choose to go with a different manifold) turbo.

An INTAKE manifold, preferably a 1G 4G63T type or sheetmetal (I do not know your engine bay design or I could suggest an appropriate one).

A throttle body that fits aforementioned manifold.

A turbo that fits above mentioned flange style exhaust manifold.

Oil feed and drain lines.

A 4G63T oil pan of correct bolt pattern. I assume 7-bolt.

A down pipe (most likely custom in design)

A custom catback system.

Preferably the water lines from a 4G63 to pipe in water feed and return lines for the turbo.

Management for larger injectors, and spark curve. The CORRECT way to do this is an AEM EMS or other such standalone.

All aplicable sensors.

Larger injectors, at LEAST 450cc/min@43psi

upgraded fuel pump

a 4g63T fuel pressure regulator or some such aftermarket one that references pressure based on manifold pressure (boost) at a 1:1 basis.

I am not sure of your knock sensor but I would change to a 2G one JIC.

an INTERCOOLER, either side mount (small turbo) or Front mount (large turbo).

Intercooler piping.

A compressor bypass valve (blow off valve a.k.a. BoV)



Now keep in mind that if your CR (compression ratio) on your pistons is too high you will either have to 1. run low boost levels or 2. rebuild the engine.

Your engine internals (pistons/rods) may or may not be able to handle the stress from a turbo at higher pressure so this make also become a problem.

Your clutch will probably go to shit too.



As you can see it is an involved project to do correctly. You can go a cheap route and spend $3000-5000 for a hahn type kit but I PROMISE you that you will regret it. They're done ass backwards and cause problems, if you do not believe me, ask Patrick (BoostedGS). They use piggy back devices and a bunch of other shit. This is NOT the right way to do things and will cause you trouble and heartache.

If you would honestly like to turbo it AND it is a 4G64 2.4l I4 I willl gladly give you advice.

Or you can spend $3k on a 90-91 1G vehicle. It would be turbo and AWD

or $5000 on a 95/96 2G turbo AWD...

[ryanman]

and worry about crankwalk

[v413nc3]

he's already got a 7bolt 4G64 problem... :)

And if you get a 95 you might get an early production 94 made vehicle and get lucky with an evo I block (they're EXTREMELY rare but they put a few in the 95's because they had too many)

DOH!!

[hoffman]

a good friend of mine, Tim, who owns speed-design did a turbo 3g. if you want email him and ask him all about that nightmare. if his story isnt enough to scare you, ask anyone of us that have ever turned a wrench on Patrick's car.

DON'T DO IT!

[DlandryTSI]

Heh yeah his car is a PITA. But its mostly Hahn's fault for having a shitty design.

How can you tell if its one?

I know my 95 was made in like sept 94'. Just curious.

[Dallas J]

Oh yeah, thats the car date...I dont know the engine date, and itll be another 3 months probably before i'll be able to check it too.

-Dallas J

[v413nc3]

The engine number.

-Dallas J around 92.5 and up = 7 bolt

[v413nc3]

He means which 7 bolts were EVO I blocks.

The engine number is the only way I know of telling. There aren't many of them out there. They were only put into the early 1994 production AWD's and from what I've heard they only put them maybe 5% or so of total produced during that time.

[hoffman]

hopes he has an EVO block for bragging rights :p

[v413nc3]

LMAO, there were VERY VERY few.

If you wanna keep the 7 bolt setup go find one :) Or just switch to a 6bolt.
