Can't hurt to smooth the incoming airflow. Personally with lower compression pistons I'd have put something more effecient on it but thats just me.

:-Pah hahahahahahahahahahahahaha. . Hahahahahaha r u kidding me. Porting a sc out means fine smoothing airflow and opening it up for more cfm. And less heat.... And ect so of course itll help. Anything to lower the iat2z and create more air at a lower flow of air will help! [/B]

Considering u think u know what ure talking about doesnt count. Boost dont equal power but more airflow on less boost does.. So say ure maf airflow is 35lbs at 3k rpm and then u compare the whp difference on the same engine and ect with the same.boost level as before and.rpm but the maf.lbs is 40lbs. Which one will have the better.power.curve./ whp..... Makin a product that creates more cfm at less.boost means a safer boost and a.safer.power. Which also means if op were to say get his sc ported and install a 2.6 or leave the pulley that he has now. He will make better power with the port job..... Goin turbo is his best bet it truly is but its a dd and ect.... o][/B][QUOTE=MP Cobalt;5960708]um i know what i'm talking about but that low of compression and a m62 is pointless the m62 cant force that much air your best bet would be to go turbo OP[/QUOonsidering the fact that boost dont equal power u dont know what ure talking about.f

I built my first turbo set-up for $2500 (this includes EVERYTHING, even a new 3" exhaust system)... sold my GM Stg2 S/C set-up for $1000, and the GMPP Exhaust set-up for $500.
And I went with the more expensive Vulcan Intake and Equal Length Manifolds (Was $1300 worth of manifolds at the time). Replace those with a $100-$200 LK9 Manifold and a $300-$400 Log Manifold... and that's a huge chunk of change saved.
I just helped my friend turbo his Cobalt - only spent $1500-$1700... and sold his stock S/C stuff for $1000.
And why WOULDN'T you have enough room? They make a turbo HHR... and plenty of HHR's have upgraded to larger turbo set-ups.

I put my first set-up together myself. Individual parts from many different shops.
