Eclipse 3000 GT Engine Swap Decision

[SLArcice]

Hey everyone, getting frustrated to all hell trying to find someone locally who actually knows what the hell they're talking about lol so this forum became my result after reading a few posts and actually being quite amazed. Anyways, I stuck this in the general information area to maybe even catch a couple 3000gt owners drifting off and taking a peek lol. Anways, to the point:

I have a 1999 GSX Eclipse shell heading my way, roughly $500.00 - $1.000.00, a set price has yet to be agreed upon. In the long run there will be the hope to have an 10-12 second 1/4 as well as a 120 mph touring car for roughly 4 hours long, breaks here and there but nothing to extensive, maybe 15 minutes per hour.

Anyways, considering how cheap the shell will be, there will be roughly a 10k starters budget for performance. Curious as to see the biggest Mitsu engine I can slam in this thing, enter a 3000 GT vr4 engine. If I'm not mistaken HP raiting roughly 300 horses 3.0L V-6, 60 degrees, Front Transverse, Twin intercooled turbochargers. Stock GSX, 210 horses.

Anyways, it's quite obvious by anyone an engine built to withstand twin turbo's have more perfomance potential in the long run. However would this swap even be completely possible while maintaining the AWD, the tranny, ect. As well as would this make a decent touring engine? Or would I be better off just going and starting a bonfire under my hood now. Keep in mind, I know I'm going to get a lot of "Just go buy a 3000 gt" comments, considering price, ect. but the idea was to keep an eclipse (personal preferance) and perticularly the AWD system since this will be a touring car dodging traffic left and right at high speeds between Las Vegas, and Cali.

A few more questions pop up as well if you guys don't mind lol.
How good is the aftermarket availability for the 3000 gt performance parts and price?
Common engine swapping prices? (I've been quoted 800 to 3k for a typical engine swap)
And, of course, how well do you think this would work for performance in the long run?

All the money your gonna spend to throw a v6 in there is gonna cost a lot, youd be better off spending it building up the 4g63. As in, instead of spending x amount of money putting a 300hp engine in the shell, you can spend x amount of money and push more then 300hp out of the 4g63.

you can build an 8 sec car off a 6bolt 4g63 engine. and i bet you will never do a swap

And that's the end of that. There is no reason you should get that swap done, other than for he sake of being different.

You are going to go through a heck of a lot of trouble and money to get that engine to fit, and to run turbos on there. Like TreeFrog says, we've got 8 second 4g63's out there. With the dough you'd "waste" getting that V6, you could probably get a 6-bolt, a TRE racing tranny, a bigger turbo, and air/fuel upgrades for your DSM.

That is simply not true, the fundamental thought process here is flawed. Its kinda cool to say "I got a twin turbo V6 under my hood", but that won't settle well when you get smoked by a 4g63 GSX with a 16G. 4g63 potential and upgrades have been vastly documented, from the power gains from a host of turbos, to the detailed swapping of 7-bolt to 6-bolt, there is nothing you won't find archived. You even have 4g64 DOHC conversions, and AWD Spyder conversions. The 3000GT swap, however, is something I have yet to see done... if youv'e got money to burn, I'm all for it, but if your like the rest of us, trust me and others on this forum; upgrade the 4g63, ditch the V6. Just my .

Listen to the almighty Shpy.

There's no need for a twin turbo setup on engines anymore, one large turbo can easily and more efficiently do the work of two smaller ones.

agreed!

[gthompson97]

there have been many, many guys with 12 second 4g63 dsms for what...maybe $2500?? with 10k you could very very easily get into the 12's and probably 11's. don't quote me on that but depending on how you budget specific parts, you could very easily have a very very quick car, and for way less the money than you could dropping in a vr4. and personally, i'd rather say a 4-cylinder just whopped your ass than a 6, it's just that much more of a kick in the face

[SLArcice]

Would this DSM builld last a touring race? And yeah, that is true, a Bigger turbo can easily compensate for having a twin, however both twins can also be replaced with bigger turbos just the same. The idea is to offset the boost to completely eliminate turbo lag, as an example a 800 horses s2000 with the same custom setup. Anyways, I'm not justifying the swap, but answer the question as if money is not an object. 10k is not a capped limit, it is the first build limit.

If I do stay DSM this would be the outline for the 10k first build:

Also, one more question then, staying DSM, 2.0 vs 2.1 destroked vs 2.3 vs 2.4 liter, all custom modified by slowboy: http://www.slowboyracing.com/shop.ph...b1b66&cat=2538

[gthompson97]

you better leave room in there for a DSMlink, you'll NEED that if you plan to run 10-12's. and do you know anything about dsm's or car's for that matter? i mean not just maintainence things like changing your oil and shit like that, do you know the mechanics of a car? it's easy to pick and say i want this and that, but that is 1/10th the setup of having a 10-12 sec. car. you better start reading up now on everything you can about dsm's because there's a 99% chance that you'll run into more than just a few problems in this journey.

[SLArcice]

Trust me when I say that I've already met that conclusion. As for that being 1/10th the setup, a lot of considerations based on those parts are also to be taken. That set up has been rated in pushing 500 horses + (hence the 2.1 liter destroked can withstand roughly 650 self claimed horses, which is why I was asking for some further comparison) This does not include a rough loss when it actually meets the tires and pavement, maybe losing 100 more horses worst case. Not to mention cranking the boost up changes a lot of factors and numbers along the way as well. This is a STARTING PLATFORM WITH A 10K STARTERS BUILD please keep that in mind. Not a final product without further advancement.

Keep in mind that besides this there will be extensive, and I do mean extensive, weight reduction plan (not everything entirely legal... or safe for that matter) but all that is going to be personal fabrication, and little to no cost considering how I will be doing all the work myself, that's why none of that is included in the build cost.

As for how a car works, yeah, I work in a shop restoring muscle cars (big kick in the nuts I'm buying a tuner instead muscle to those I work with, but hey $3per gallon of gas is $3 for a fricken gallon of gas) turbo chargers are less my area, when it comes to a v8 superchargers reign supreme. I'm here for aid in my shady areas, so if knowing everything is required to ask for advice then I guess not a single one of us would be here right now. If you look at that setup and disprove then go out of your way 2 minutes and list a better part instead of asking the person if they know what they're doing.

[ted_ex]

First off, stick with the 4g engine. Second, on your list you need the following additions:
front mount intercooler
transmission
exhaust manifold
exhaust
other drivetrain parts?
intercooler piping
radiator
fans
MAF?
Depending on how complete the shell is you might need a lot of other stuff like alternator, PS pump, etc......
Also, the e-manage isn't the most popular route for DSMs because in my opinion there is a lot of better options like DSMLink or AEM or something else similar. Good luck on your project though, there is a huge amount of info for these cars online so you can always find answers.

[Nayr747]

I think you could find some better parts. Everything you want is from one shop? One small shop isn't going to have the best of everything.

You can do high 11s on the Evo16g. And that setup doesn't cost near 10 grand. If you've got a bunch of moeny I would just go to a shop near you (someone can probably point you to one close in Cali) and tell them what you want. You're gonna run into resistance with engine swaps and spending money frivolously with DSMers though.

[TreeFrog]

again you will never do it, so there is no need to us to keep posting this. YOU WILL NEVER swap in that engine, i promise you that. You come in with 3 post and shoot off your mouth about stuff you know NOTHING about.

[Whathits14]

Fastest 4g63 is faster than the fastest 6g72. 2x 20g turbos for a properly built 6 cyl tt =10s, and for the dsm, 1x 20g properly built =10s. Therefore the argument of turbo lag really doesn't adversly affect performance when compared to the 1/4 mile performance of tt setup. For spool, yea tt will be faster spool, but not always faster overall. That slowboy setup should be good for way over 600WHP. Which can = low 11s, mid-high 10s. The fastest stock body dsm is sheps 2.0L. I would get a stroker if you wanted to run a street monster, 2.4L would make spooling a huge turbo easier than with the 2.0L. Although I do like the idea of a engine running past 10k (2.1L) I can't think of any turbos off hand that would provide good boost that high into the rpms without being HUGE and not getting intial spool until very late in the stock engine range (5k+)

10k will get you a great setup, built engine, supporting mods, and a large turbo. Ditch the greddy inejctors, get FIC or denso as good or better for less. Also, check out BB turbos, they are faster spooling, more efficient. Make sure whatever you do for this car, that you get a 6 bolt engine.

Of course to get any of these crazy fast times, you have to be able to drive like a mo fo.
