It's been mentioned, not sure if porting the m62 would provide any gains on such a small motor.

 

I think I might try it.

 

I dont think anyone else has tried on the Cobalt, if you do, be sure to let us know how it went.

 

The M90 swap will be a better gain.

 

If you do it through them you better be made of money, there work is expensive 995 to get it polished and ported. Seems like a lot for probably minimal gains out of our set up. Unless you plan on major HP

 

Thats if you want the outside of it polished but just the port job is $500

 

Oh well thats better but i would ask them if you got this done and sent back dyno sheets on the improvement if they would discount it for you since other people are interested but want to see results first. I would be interested if its a good 20 FWHP or even if its 15 FWHP. Just a thought
