Ok so im getting a 2.2 ecotec. Should i throw a turbo or supercharger on it because im lost in which i want to do what do ya'll think?

It is mainly personal preference and power output goals.




its an old concept. time for something new to take the reigns. - Z yaaaa

Turbo is more maintenance, issues, and problems, more work finding parts, harder to tune....turbo will yield more power in most applications. more parts to go wrong....

Supercharger is bolt on and go.


I would still rather have the turbo on my car than a supercharger. Its been more headaches and pain and money but its been fun too. I wouldnt trade it for the world. Dont get me wrong, SC is nice because its bolt on and go and reliable, but im just in love with the turbo stuff on mine. So much to customize and work with that no two kits have to be the same. But yes a TON more work and money into turbo that supercharged.

Well im looking to boost hp of course. But im wondering which will affect my mpg more than anything.

There's no definite answer to that. Different size turbos will different amounts of power and different mpg (due to the difference in fueling needs), the same supercharger could yield different mpg's depending on the pulley/injector/tune combo, and same goes for comparing the 2 chargers...
It really depends on your goals for the car...as you reach more and more power, your mpg will inevitably decrease. Is your car a daily driver? Fun weekend car? Etc?
If it's a daily driver and you're concerned with mpg, I'd say both the m62 supercharger and Saab turbo kit (or a similar sized t3/t4 etc turbo) will get you in about the same ballpark power and mpg wise.

Your tune and how you drive will play a huge role. Im running a 3.1" pulley and 60# injectors on a m62...if i really romp around on the gas pedal and constantly boost the car, I'm down in the 20-22 mpg range...now on the other hand if I drive more conservatively on a regular basis and try stay out of boost in regular driving conditions I'm closer to low 30s mpg.

Turbos are easier to make big numbers on than blowers, and have a bit more options on customizing your setup, but superchargers have the benefit of being more of a bolt on affair and on a stock pulley can achieve pretty decent mpg. Like Vince said, it's really a matter of preference, and more than anything dependent on your specific goals for the car.

Either way if you're not building the engine you can only make 250 hp before breaking stuff, the blower can make that much for about the same money as the turbo. But the blower will have a fatter torque curve, making it a better daily driver too.

I was at 280 whp on a stock 2.2 eco, and there are a bunch more that have gone higher then that on a stock L61 and it's handled it, it's all in the tuning.

Agreed.

I think they all had better then average tuning. So again it is all in the tuning.

Supercharger is a really fun DD.

the m62 supercharger sounds like the way to go because it is my daily driver and something fun for the weekend such as car shows lol. Plus I was tired of going to cruise ins and shows and not being able to lift my hood due to the fact that I still had the stock motor in it lol.

You do not need to have a supercharger or Turbo to open your hood at car shows.

Just spend some time and clean your engine bay. Maybe paint the IDI cover. Polish small things.

I got a old beat up 2.4 thats dirty ive used engine degresser and never dull lol just cant seem to get that shine like my dad use to get on his maro. But anyways i still want power and i was thinking about powder coating a couple things.

Confilict of interests!! Lol, but i know exactly what you mean. Everyone else has summed it up pretty well, but i'll re-enforce the point that mpg, before all other things, is dependent on your right foot. I could build a 400whp turbo car that still gets 30's mpg highway, but likewise, you could build a stock M62 kit that gets high teens or low twenty mpgs. Tuning is very important, but so is your ability to control your right foot if you really care about mpg.

I actually get better mileage with the blower than I did stock. Likely because my tune is better than stock, even though its no where near as good as I want it to be.

I only have a heavy foot coming off a clean stoplight or when im riding with friends other than that i stay conservative due to the gas prices :/

My MPG dropped with the charger. I was getting around 34mpg n/a and tuned. now around 29mpg. I believe this is do to the 2.5 pulley on the M45.

On a M62 I feel it would be better.

Trust us when we tell you once you have boost you will have a heavier right foot.



FU Tuning

I can say my mileage is 30-35 with my foot out of it, but i mean come on, a turbo, blow off valve..... how often is my foot out of it short of cruising on the interstate haha.

I say neither, nobody puts puts boost into Jbody's anymore.

I got 26 when I was stock, and now I get 28, that should go up once I get an exhaust and dont make boost by just looking at the throttle.
