ok so ive bought all the apperance mods i want for my car and i am now looking to buy performance mods for it. i have an auto 2.2l 5 with k&n shift plus and gmpp intake. My question to you guys is should i start collecting parts to go supercharged or go fully bolted with other suggested mods. Any suggestions and comments would be appriciated thanks.

If your saying fully bolted please post a list of what you would get thanks

or any other parts you think would improve acceleration

SC sounds sick and you get pretty good gains for a decent price... I say SC!

yeah i was wanting to go with supercharger with some upgraded stuff but didnt know of being an auto would effect that

why not...fully build the engine? THEN s/c? thats what i plan on doing. but if you're looking for RIGHT NOW...i say s/c

as much as i would love to do that this will be my dd and i want it to run good and crusch all of my friends cars along with anyone who tries to mess with me but i am also building a 81 camero which i will be building the full engine for so i will not have the time or money to do that to my 5 which is why i have to chose between the 2 probably

If you're gonna fully build you might as well go turbo cause the motor will be able to handle it, but you can get over 200 whp on the stock internals + M62 for a lot less.

ok i will probably go supercharged then just need to start getting a parts list together is there a post on which would give the 2.2 most pull for the money

and how much of a money difference am i looking at for a stock supercharger vs one with a few upgrades

whats fully bolted considered?

i was going to go with a header and full exhaust, 2.4 intake mani, have gmpp intake

Mike85220

It all depends...
Do you have $1500-$1800 for a used SC kit?
The install costs around $750.

Racing Solutions Header: $220 w/ shipping
DP: $280 w/ shipping
2.4 manifold: $280 w/ shipping
2.4 TB: $80 w/ shipping
Custom mandrel bent 2.25" exhaust w/ cat : $600
Trifecta tuning: $300

It will be around $500 to install the header, DP, TB and manifold unless of course you install it.

It is $1760 for the above bolt-ons.

I hear with the above bolt ons plus yours the car is about 170hp at the wheels and will cost from $1760-$2260. The drive train soaks 7% of the power, so this should equate to 181.9hp at the motor.

The SC mod is around 210 hp+ at the motor and will cost around $2250-$2550. The 2.0 is at a lower compression, and a slightly smaller displacement with the same SC attached. So it 'should' be around 210 hp on a 2.2 liter.

Drivetrain loss is 10-15% on FWD vehicles. I believe most are seeing around 12% on average on the cobalts. And without cams I guarantee you wont see past 160whp(being VERY generous). Remember, completely stock these motors dyno around 120whp. I made 123whp/132wtq stock. So just opening up the exhaust and intake isnt going to yeild 50whp. Thats ricer math. You WILL need cams. 160-170whp for stage 1, 175-185whp stage 2.

From learning from Jerry's build(specially being able to see it in person) I believe what he spent is pretty accurate as to how much a SC build would cost. I believe his came out to around $2000. He also has some issues us cobalts wouldnt run into, so I'd say thats pretty good. Plus guys are almost maxing out the M62 on the stock L61, Its not worth building the motor first then going with the M62 because it wont make enough power to warrant a fully built motor. Its like if I were to settle for my little TD04H turbo, which will only flow about 280whp worth of air. My motors built for 500+hp. Might as well put it to good use...

Mike85220

I actually calculated it by the dyno tests off the J-body forum.

Guys with the older 2.2 Ecotec that has 8 less hp with the same mods listed are getting 165hp at the motor, not the wheels that is my mess up. So if they are getting 165hp at the motor, how much is a Cobalt that starts at 148hp at the motor going to get with the same mods?

007CobaltLS

You are forgetting that he's auto...he's losing more than 15% due to drivetrain...I had my car dyno'ed stock and it was 112hp/111tq. That was on a dyno dynamics dyno and I think it's a little low, but not too far off (I think it would have been about 120 if I'd gone somewhere else...I don't think the person who dyno'ed it really knew what he was doing).

Intake, 2.4 TB, 2.4 mani, header, dp, cat-back, tune should net you around 180hp at the crank is my guess (maybe a little more).

Mike85220

Yeah, the dyno is more for doing before and after than getting an actual max output reading it seems. Some are more accurate than others and I also hear some shops rig the dyno so they make the customer happy with big gains that don't exist.

I think I'm going fully bolted for now, saving up and buying a used ss/tc or something outside the GM family...

Mike85220

I realized that the dynos on the J-body forum were for at the wheels ratings.
As such, it would be more like 170 at the crank for a Cobalt 2.2 with all those mods.

With a stage II set of cams, it could go over 180.

alot of good info here thanks but either way i go i am going to spend little by little until around christmas where i could get the rest of the stuff and is that a stock m62?

NJjon

Sure, if this makes sense to you go for it.

But think about it, if you're gonna go s/c, wouldnt you want to upgade your exhaust, dp, and header as well? Plus you still need a tune. So if your going supercharged, you might as well buy everything except the 2.4 mani and tb, and get a full h/d/e set up. Which will cost you 1400 "installed". But quite honestly, if you can't install that, then theres no way you can install a supercharger set up. So then add more money to the supercharger pile.

I honestly think that post was extremely biased towards going supercharged.
IMO, get your header, downpipe, and exhuast (under a grand if you install yourself), and then save up for your supercharger.

but if i get all of that for my 2.2 will it still work with the superchrager i know its kinda a stupis ? but wannt make sure

nicksredline

i beleave u can put together parts from a 2.0t sabb for cheaper than what ur gona need to go s/c so if i was you i would go to a junkyard and quite all the pices from a sabb ... ask most lsj's the whine is great but i wish i had a turbo that i could just bump the boost controler up on and make more power... ya know lol... no need to swap pullys( which is not hard once u get a modular system) but still i would go for the saab setup.. descently cheap and easy to upgrade for even higher hp lvl's
