I have an automatic 2.4L solstice coupe and I want to put a turbo/supercharger in it but have no idea where to start. I am clueless on this subject seeing as I can’t even change the oil on this car. I would like to have some real power preferably faster than the stock 2.0L turbo solstice (would hate to dump money into the engine and still have it be slower than the gxp model). I use this car as my daily driver and need it to be extremely reliable, and last. I am a public school teacher and I earn a teacher’s salary therefore, I would like this upgrade to be affordable (not cheap just biggest bang for my buck), yet I am willing to pay more for reliability and power. Should I go turbo or supercharger, where can I purchase everything I need, etc.
Oh and as I mentioned before I will certainly not be the one installing this… I live in the Dallas TX area, I know it’s a long shot, but does anyone have an idea of a good reliable shop that could install this?

You have your home work cut out and a lot of reading to do before you make your decision, do you know the difference between a turbo and a supercharger? That is a good place to start, once you decide which direction you want to go, then most of your questions AND costs could be easily answered..I would say that google search here and on the WWW is your friend.. However I'm sure others will chime in with there point of view..I would also look at some of the sponsors here, as many do either or both upgrades, it is just a matter of what 'flavor' you want.. and how big is your bank account..:D good luck with your quest to upgrade.. Oh yea, welcome aboard!!

Welcome to the forum.

Turbocharger and Supercharger systems are available through 4 forum supporting vendors.

DDM Works, DDMWorks - Automotive Performance Specialists offers both supercharger and turbocharger systems for the NA.

DeJon Powerhouse, DEJON | Powerhouse offer turbocharger systems.

Hahn Racecraft, Hahn RaceCraft Homepage offers turbocharger systems.

Performance Autowerks, Welcome to Performance Autowerks! offers turbocharger systems.

For each of these vendors, you would need to deliver your car to them unless you have a local installer that can do the work, since you indicate that you are unable to do the installation yourself.

If you need the car to be a daily driver, I would suggest that you don't go too extreme. If you want more horsepower than the GXP, it's best to start with the GXP and add modifications. Reasonable modifications to the NA can get you into the same performance area as a GXP.

Use the search feature of the forum and do a lot of reading before you start this project.

Good Luck!

I had the Hahn stage II turbo kit in my car for a couple years and ran that thing through hell and back and it has held up fine. Now I have the stage III and it has quite a bit more power then a stock 2.0t. It spools pretty quick too.

I think the stage II is the best bang for your buck.

You might find this interesting


http://www.solsticeforum.com/forum/f11/tuned-gxp-vs-ddm-stage-3-supercharger-63176/

My personal experience is that the Stage 3 supercharger is basically equivalent to the GXP with the GMPP tune. A little bit more on the bottom end and a little bit less on the top end.

With a 2.4 you are not going to be doing a lot of boost because they are not designed for high boost levels. If you were my brother, I would tell you to choose the supercharger. Its a very proven, simple design that works very well. You get more boost low down where you are driving most of the time.

And it sounds very cool!

1st off Welcome

There are a handful of good tuners/shops in the DFW area. However, I do not know of any DFW area speed shops that specialize in GM, or more specifically Kappa tuning. Nearest reputable GM tuner I know of is Houston area. On the other hand, I do have personally experience with Jotech Motorsports & Cobb Tuning. Both have solid reputations and plenty of their work running the roads in DFW. Tony @ Jotech has helped me source several hard to come by parts for personal projects since I moved to the Dallas area several yeras ago. Every time I've interacted with Cobb, they have been extremely knowledgeable, helpful, and professional every step of the way.

Jotech is in the Richardson/Garland area. Cobb is about 15 mins up the road from them in Plano.

I would suggest deciding which route (turbo or super charger) you plan to take and which kit you are going to source, then ask them if they have any suggestions on local tuners as well. Regardless of which tuner you decide to use, just make sure it is someone you get a positive feeling about from the start, they have a solid reputation, and satisfied customers. The more time you spend researching up front, the more likely you are to avoid problems in the end. I think this is even more important if you do not work on the car yourself. Any time you have an issue, you will need to take it somewhere or to someone you can trust, who understands and can work on your setup.

That being said, DaveOC has a valid point. Why not look at a GXP? I personally like tinkering and turning wrenches on my cars, so the the aftermarket turbo/sc route and options appealed to me. If I did not work on my own cars, I would go the GXP route. If only for the reason I assume it should be easier for a non-specialized shop/dealership to work on your car when it breaks.

Either way, good luck and have fun! :thumbs:

There is a current post on this forum about a guy selling his 2.4 and considering selling his stage 2 S/C seperately. You might want to consider scooping up his stage 2 package for 3000-3500 and having a local shop install it for you for around 800 and 1 days work. This is basically the route I went. I have a DDM Stage 2 setup I bought used. It's been awesome and worry free for nearly 5 years now. It has been very well supported by DDM and keeps up with the GXP's just fine.

As others have said, there is lots to read about both T/C and S/C options on this forum. Personally I think the S/C option is better for a daily commuter - which mine is. As to value - this is the cheapest 100HP you could add and it's worth every cent.

have fun, good luck

Best bang for $$ and reliability is a GXP (any oem will be better than modding that way). BTW, add an aftermarket clutch to any turbo or stage III base solstice. Or slip slip away eventually.[/QUOTE

Still on the stock clutch with 320+ whp. No slipping at all either. I guess I'm a lucky one. :)

I repectfully disagree on the first point and have a Stage 2 with a stock clutch and 40,000 miles since I supercharged, so can say with all honesty that the second point does not apply to me either.

I agree with kwtoxman.... I have the Hahn stage 3 and my clutch couldn't take it. Replaced it with DDM's clutch and have been happy ever since. New clutch will be required with the stage 3. :)

Maybe I should have said if you drove the car. lol (a funny). Anyways, clutch slip definitely happens and you can search the forum for more.

King Oka directly contradicting himself here....

I never find your quips funny Tox. As to contridicting myself, well I suppose you could say that. I DO recall getting a little slip once or twice when launching in an all out "go for it" mode, but the OP and I regard the car as a daily driver, not a racetrack beater, so it is not a requirement for a stage 2 setup to get a heavier clutch. Yes, Stage 3 seems to be the line. Never argued that fact. Still runnning the original stock clutch 3 years after that post, so I guess I'm entitled to change my mind.

Also folks in the past have suggested selling 2.4 and replacing with 2.0.
Folks in the past have also had their 2.0 l engines replaced and rebuilt. Also I know of one 2.4 that required a rebuild after a Turbo was put in. I personally do not know of any 2.4 S/C setups that have detonated under daily driver threasholds.

Since you are an automatic, you will not have to worry about replacing your clutch and the automatic transmission will hold the power that the stock 2.4L can take.

There are of course several options available that are in this thread from our supercharger to a couple of turbocharger kits out there.

If you are looking for a supercharger, we are the ones to go to, as there is not any other options out there. If you are looking at turbos, we can supply that, I believe Performance Autowerks can do automatics now also, but last I heard HAHN was not able to do automatics you will need to check with them. The tuning is different between the manuals and automatics because of how finicky the automatic transmission controller is on these cars.

So I would say your first step is to figure out if you want a supercharger or turbo, then go from there.

Let me know if there is any other questions I can answer for you.

Thanks,
Dave

No biggie. I find your posts hilarious. :lol:

It's all just your history of fast and loose posting over and over again.


As for your original post and your last post....
I repectfully disagree on the first point and have a Stage 2 with a stock clutch and 40,000 miles since I supercharged, so can say with all honesty that the second point does not apply to me either.
so it [a clutch] is not a requirement for a stage 2 setup to get a heavier clutch. Yes, Stage 3 seems to be the line. Never argued that fact. Still runnning the original stock clutch 3 years after that post, so I guess I'm entitled to change my mind.
WTH? WHY are you talking about a clutch for stage 2??????? No one has talked about needing a clutch for a stage 2 in this thread and I never said a clutch was needed for stage 2. :willy: No one said it "applied" to you either. :willy: My links are to support the fact that a stage 3 will need a clutch. Yet you keep going off on that tangent.....







Back to what the OP wants, Rob summed it up early and well in this thread that with the OP request...
I would like to have some real power preferably faster than the stock 2.0L turbo solstice (would hate to dump money into the engine and still have it be slower than the gxp model).
.....a stage 3 supercharger was needed, even just to keep up with a GMPP tuned solstice. His link also showed experience where without a better reaction time in a stage 3 supercharger, GMPP GXPs were faster.

Except if your king-oka with a stage 2 supercharger, then your as fast as a wester's tuned gxp! :jester::barf: From here...http://www.solsticeforum.com/forum/f93/worth-build-gxp-better-56751/#post852440
My stage 2 DDm on the 2.4 engine can run away from a stock GXP or Redline and could likely keep pace with a Westers tuned 2.0 turbo.





Well, lots of info in this thread for ya Staygold.

Lets be accurate shall we.
1) a DDM Stage 2 S/C setup is faster than a STOCK GXP under most driving conditions. The OP wanted to be faster than a Stock GXP. If he wants to be faster than a GMPP tune, then a Stage 3 would indeed do the job - and his (automatic) clutch will hang in just fine.
2) The OP has an N/A so a GXP conversation should end there. The rest of the conversation should be concerned with what mods he can make that are simple, easy to maintain and have lasting properties. To me ( my humble opinion only) the DDM Stage 2 setup is exactly that. Certainly trading in his N/A for a GXP is an option, but not really a mod now is it?
3) A lot of assumptions were made on this thread by one of the posters. I think that poster should try driving one of each configuration (Stock GXP, Tuned GXP, Stock 2.4 and tuned 2.4 in several configurations), before flapping his lips. I can assure you I am not that "fast and loose" poster, as I have done exactly that.

Please don't make the effort to mis-quote me again Kwtoxman, and - oh yeah - try reading the thread before you post to it.

Keep ignoring and twisting away. :)

1. Faster, faster, faster! LOL. Keep telling yourself that, whether its stage 2 to stock gxp or stage three to gmpp (factory tune, which everyone and there grandma runs). :cool: Continue to ignore the stock gxp dynos out there at 235 whp too, just like DDMs stage 2 supercharger website 235 whp. Also no need for me to post any ACTUAL stock gxp 1/4 mile times showing the car doing similar times to ACTUAL posted stage 2 supercharger times, as you ignore it. It's obvious you don't care about all the other posters who also find a stock gxp as fast as a stage 2 supercharger, you ignore that as well. http://www.solsticeforum.com/forum/f93/ddm-stage-2-1-4-mile-time-73398/#post1099372. As for stage 3, well, that was already asked, answered, and ignored by you too. Nothing new here. Same story for years.

2. Conversation can go wherever. Sorry these options don't fit with your option paradigm.

3. This is getting too funny. No assumptions here, just lots of supporting data and tons of real world experience in the earlier posts. And funny man, I've had plenty of experience with all these solstice configs and lots o lots o solstices. As well as at the track with solstices. Having lived in a population of almost 20X the okanogan (and 3X the Greater Vancouver Area) helps. Still, you may as well continue your pattern over years of ignoring all this information stick with your personal conjecture and ad hominem attacks.

And let's not wreck your dream world with reality here. ;)


By all means a supercharger and turbo upgrade to the base solstice will help alot and are great options. But it is important to show what the overall forum experience is with regards to GXP comparisons because of the OPs specific expectations. It would be a shame to see the OP spend money with expectations for mods that aren't met. I'd much rather make sure the OP is happy, than play fast and loose on the numbers, like someone else, and set him up for potential disappointment.
