Turbo or S/C??
Thursday, March 15, 2007 9:04 PM
I honestly can't decide whether i want to turbo my ecotec or turbo my ecotec? and that reason is because i dont know much about either of them....Can anyone help with some pros and cons of both of these? Maybe make my decision easier? I would like to do one of these in the future, but i wanna learn more about it first. Thanks

well if the decision is either a turbo or a turbo, id go with a turbo......
now if ur talking a supercharger, then id go with a turbo.

It also depends on what ur looking for..... if ur looking for raw power and wanna build a street sleeper, by all means go with the turbo.
If u just want something a little bit quicker and more reliable, then go with the supercharger.

yea, a turbo is a good way to go... i would suggest learning about both in great detail before u start thinking about installing anything. forced induction isnt something you really want to mess around with untill you know what it does and how it works. either way you go im sure it will please you! good luck!!

I am taking the turbo route and while our application may be different just because it is complicated time consuming and obviously hard work not to mention expensive ....it is still fun if you like to enjoy things in the long run....it isn't impossible obviously have fun with it find out your preference and get goin as for me I have an extran long block to mess with in the garage but it wont be till next year when things will be coming together for now parts parts. and if you don't wanna chunk a motor before its time put things togerther before you beat them up

It cracks me up when people make the argument that turbo is where the big power is, and yet most people with jbodys rarly break 200whp with any given turbo kit and have loads of problems when NOT installed correctly.

the turbo sc debate will never end

well turbochargers are more effiecent, but don't kid yourself, superchargers can make tonnes of power and tonnes of torque. As far as reliablity goes.. I personally think it is up for grabs.

In my opinion, I believe reliability is in the users part. If you beat the crap out of your car with a f/i setup, you will probably have negative results in the end. Dont get me wrong, if you go about putting this on sloppy and half assed, this could also result in engine failure. I myself have just chosen the path of the supercharger the other day. My reasoning is the ease of install, the ease of a reflash, and costwise, the hahn stage 2 just wasnt in my price range.

Here is the main difference, in my mind. People cry and cry about reliability, but keep this in mind:

The GMSC kit (M45 and M62) had years of development, testing, and engineering put into them. They are the product of the best parts available to GM to make a proper and reliable supercharger kit.

A good percentage of home made turbo kits, probably over 95%, contain shortcuts. These shortcuts may be in materials used, time taken, knowledge, engineering, or a combination.

The end result is a lot of ambitious turbocharged projects literally blowing up in one's face. Creating a proper turbocharged setup requires money, and lots of it. You need GOOD parts if you want reliability, you need knowledge, you need experience (be it yours or somebody elses), and you need to be WILLING to take your time to do it right the FIRST TIME. While I have had issues with a headgasket blowing while turbocharged, etc, I am YET to have an issue with my over-engineered turbo kit. It has performed since day one and never let me down... I can't say the same about isuzu transmissions...

My point is this: you cannot cite reliability as a factor for choosing to go turbo or s/c... the reliability factor is 100% up to you when you design a turbo kit.

As for power, again that's up to you. Superchargers give you different options than a turbo, some which some people prefer. At the end of the day, it's going to come down to you and your experience. What can you do? What can you handle? If there is a break down can you afford it both financially and time lost driving the vehicle? Do you plan to beat the snot out of the car once boosted? Is downtime something you're willing to accept to get more power? So on and so forth....

To be bluntly honest, every GMSC car I've ever done an install on or helped with or advised with has run almost flawlessly out of the box, (except for Sam's but it was second hand)... he has been learning first hand what it's like to have to deal with the above issues on a car he NEEDS as a daily driver. It sucks sometimes, but at other's it's totally worth it to him. But for the most part, the GMSC kits have been quite reliable and are dead easy to install. (The Ecotec kit requires a bit more swearing and a lot more beer)

So I leave it up to you, original poster... what are YOU prepared to accept. Once you know, you'll be able to easily make your choice.

Good luck.

Excellent post Chris.

I myself, when I first started looking into boosting my car I was going to take the turbo route. After getting my head wrapped around the idea, what was needed and the cost to do it, I had to rethink my plans. I wasnt really prepared to get "X" amount of engine work done and having no car to drive in the meantime. My path to the M45 charger kit was set at that point. Dont get me wrong, its a great addition to my LD9 motor, but a turbo would have been better. In the long run, the cost was easier to absorb in my wallet, and I enjoy driving the car even more. Gas on the other hand sucks, damn you boost.

My plans took 5 years before I actually did it, so I really researched both options to make sure that I wasnt going to spend my money on nothing. Since I've done the charger, a lot more options have surfaced that allow me to net even more power (water/meth, hptuners, etc.). I really liked the route I took and now my wallet is killing me once again.

I say do your research carefully and dont jump into it until you know exactly what you want and/or hope to gain from it.

Oh what a night that was...12:30am...

Me: "Chris, go to Darren's and get the fuel line disconnect tools."
Chris: "But I just got home, it's freezing cold, and I have no heat in my car"
Me: "We have a blower, we have beer, and ahem...three NVG ins-outs in a week"
Chris "sigh...I'll be there in a half hour"

Are you kidding?? I've seen soooo many posts before.... It really all depends on a few things:

1. What your realistic goals are
2. What kind of money you are willing/able to spend
3. What kind of time you are willing to put into it

Once you figure that out, along with what everyone else has said, you can make your choice.
