Supercharger build or turbocharger build
I have a 2.4 L with 20000 miles on it. I have short ram intake and megan racing cat-back exhaust.
I am debating wether to buy the supercharger or turbocharger for my car. Can some people show me options of what i need to do. Like what will I have to do to my car before i slap a turbocharger or supercharger on there. I have the cash siting and just debating which one to buy. also what are my outcomes of hp and tq. and what are benefits for supercharger and turbocharger and negatives.
thanks please help

well, look deep within yourself and ask one question. How much power do you really want? The blower route is most likely harder to do but the parts are kind of easy to come by since most of us who are already supercharged are getting rid of parts. The supercharged build will more than likely yield less power than a turbo and won't have much room for upgrades before having to look into replacing things in the engine. There are those on here who have done the swap and had successes with it.
Turbos will give more power, and there are kits out for your car now, as I am sure you already know. The turbo kits will cost more to build, but upgrades afterward wouldn't be much to sweat. They are easier on the engine, and don't rely on pulleys to provide more power. The only thing would be the tuning that is a downside, but the same companies with kits already have it figured out.

It depends on how mechanically inclined you are, or more specifically, how much you know about cars.. By the nature of your question, I'm guessing the answer is "not very". That's okay, neither am I. It's not something to be ashamed of, you just need to recognize your limitations and go from there.
Your problem likely isn't going to be with acquiring or installing the parts, but on getting your engine to work properly with them so your car maintains drivability. I'm going to assume this is probably a car you drive regularly and not something you are hoping to turn into a drag monster. This means you need whatever forced induction system you use to work just like GM put it in (or hopefully better
).
So, you basically have 4 options (in order of likely cost):
1) Do it yourself and hope you don't tear anything up.
2) Follow a step by step supercharger install and use Rebel Auto's tune.
3) Go with Hahn's turbo kit, and use his tune.
4) Make buddies with a tuner shop in your area and let them point you in the right direction.
So far as specific drawbacks and limitations of turbocharging or supercharging your car.. there are books written about this stuff.
These are some of the pros and cons I went off, but I'm not insuring my accuracy. If I'm wrong on any of these - I'm sure someone will chime in. Oh, and this installing the Eaton M62 Supercharger (from a Cobalt SS/SC) vs. installing a Garrett GT2860RS (from Hahn's kit).
Supercharger -
Pros:
- Less expensive.
- Instant boost (there's no lag with a supercharger)
- Good power gains, looking at about 225 whp from 8 psi.
- Easier install
Cons:
- Finding the parts can be difficult.
- More difficult to control how much boost your engine's getting (pulley sizes, etc.)
- Parasitic power loss (since the blower runs on your pulleys, you are losing power just by having it on)
- Decreased efficiency and economy of the engine.
Turbocharger
Pros:
- Substantial power gains (250-300 whp on the same turbo on stock internals with minimal upgrades)
- No parasitic power loss, so efficiency and economy stay similar (if not improve) when not boosting
- Less of a probability of the wheel hop and tire spin that plague the SS/SC specifically because of turbo lag
Cons:
- Cost
You should also consider before jumping into either way that you WILL LOSE YOUR FACTORY WARRANTY. This is a reality you should really consider before slapping something on your engine that could potentially blow it up or rip your transmission out.
For me, I went with Hahn's kit. Mainly because it offers the HP and TQ I was looking for (in the 250 to the wheels range), has been used successfully on quite a few Cobalts now and numerous Solstice/Sky 2.4l and because Hahn has a lot of experience with turbos on GM applications.
The drawback - it's expensive. All in all, you can expect to spend in the neighborhood of $5000+ to take your car from where it is now to the bare minimum of where it should be. That price includes the kit itself, clutch, install, and any other tuning you'd like to have done on top of Hahn's. I'd also include new tires if you're still on the stock Pirrellis and you should highly consider a brake upgrade.

theres nothing custom about putting an m62 on a LE5. it all bolts right on. And anyone can make a ghetto L bracket to hold on to the second coolant tank, and some metal strapping to hold onto the coolant pump for HE.
all bolt on.
all bolt on.
