Need some opinions.

Pros & Cons:

buying standard Sky and adding aftermarket turbo kit.

vs.

waiting for the Sky RL.

probably will be many aftermarket dual exhaust kits to choose from.

Other than the no dual exhaust con, there is also the issue of fit. It maybe difficult depending on engine compartment configuration to add a turbo, a supercharger aftermarket might be easier to add due to not having to reroute the exhaust.

From what I understand it's not even true "dual exhaust", just a split out of the muffler. Which should be pretty easy to come by on the aftermarket scene.

hmmm...thats not good...i thought it was a true dual system. On the Sol forum i'm pretty sure I read something to that effect.

Another thing is the engines, I forgot that the stock one is 2.4L & turbo version I think is 2.0 or 2.2L. So an (aftermarket) blown 2.4L may be a whole other ball game.

So true, maybe squeeze more power get us to 60 in under 5.. oh.. what would be so worth it.

I don't know of any cars in production that have i4 engines and true dual exhausts. Cars like the S2000 and new MX-5 have dual outlet exhaust, which as mentioned are two ports off the muffler.

Also one point everyone seems to be missing between the engines is actually any of the technical details of the engines. Yeah the 2.4L has displacement over the Turbocharged engine, but that's about all. The 2.4L VVT ECOTEC has a very high 10.4:1 CR ratio. Which will more then likely limit you to 6-8psi of boost WITH an intercooler stock. If the Turbocharged ECOTEC is anything like the 2.0L Supercharged engine then the Turbocharged engine will be far superior then the base 2.4L VVT engine. Forged components, lowered CR, various other beefed up parts, etc. You could beef up the 2.4L and drop it's CR too, but you're going to be doing a lot of engine work, and spending a lot of money.

If you use higher quality engine components (aka can take more of a beating) you can still get decent boost PSI with a high compression engine. Managing the output Torque then becomes the issue.

Yes, that is true. But it requires more work then what PaulWall had originaly mentioned of getting just an aftermarket turbocharged kit. With the base engine unless you change the pistons or variosu other componenets to strengthen them and lower the CR, 6-8psi with an intercooler is probably the extent of what you can do on a stock engine.

Pro:
Price from GM will be under $4k for turbo model

Con:
Do it yourself as good as GM with original engine will cost over $6K, no warranty.

Why has nobody suggested upgrading the turbo on the RL?

Now THAT's my kind of mod-think.

And it's probably gonna be in my future.

I said that several time!! :cheers:

Anyhow... I've made my search and it would be a lot costly to add a Turbo by my-self.... and I rather have a 2.0 or 2.2L turbocharged engine than a 2.4 and not only for the ratio.... but for this GM bible that makes you build an 2.2L Ecotech from stock to 1400HP step by step!

The stock RL for me with a little tweaking to the computer. I'm betting this motor is going to be heavily detuned from the factory.

Ah, but if I have to open the hood to plug in a flash-tuner for the computer, why the heck not put in a spanky-new 12-pounder or something while I'm in there!

Heehee

Yea a "Stage 1 upgrade" sounds like a minimum requirement for the Redline. Hopefully GM Performance Parts can replicate what MOPAR does for Neon's. Stage 1-3 Kits for Solstice GXP, SKY Redline, and maybe even for the Cobat SS Supercharged. There is a GMTunerSource.com website......

That PDF is a great read! It's mostly geared towards tuning for the Cobalt SS, which is ironic because it was the Lisa Kubo ION that set all the records and whipped all the ass on the quarter mile drag strip before the Cobalt showed up to try to out-do the lowly Saturn. LOL

Anyway, if you ever want to know how to tune an ECOTEC, that bad boy is the freakin BIBLE that's for sure. Reading that made me want to run out and buy a Sky, slap in a few grand in new parts, and have that thing pushing 500HP! I think you could realistically get to 400HP without any emissions problems (street legal). We shall see! :willy:

can anyone say boost controller? i'm sure the factory turbo won't be maxed on the production version...

also other basic turbo mods like bigger exhaust when upping boost, etc., and we should see some pretty EASY power out of this car, no questions. putting on a bigger turbo might not be what most are looking for in this car, it's a roadster. how many people want to floor it into the curves to have the boost come on sudden and HARD only to have the rear kick out on you?

not me, i'll probably stick with the stock turbo if not maxed, and just increase total output on it. it should take it easily...
