who has blown there pistons at 350hp??
havent seen it yet.. point me to the source please..
i have worked with this ecotec engine alot
my ion, cobalt, sky and hhr as well as over a dozen customer builds we have built
i have not had any internal problems with any of the cars we have worked on for the past 3 yrs and a couple have been over 350hp mostly in the high 200 low 300hp range

I don't think you need to worry about piston until 350. Once the turbo kicks in it will produce boost more efficiently. Its really the pressure that will kill the pistons, along with bad tuning.

yeah i think im good with the mods im planning on doing for sure, rods,heads and all that i dont think will be needed. and also in the gm build book doesnt it say to change pistons for the 2.2? if you pay attention to the 250-400hp build itll suggest to use alot of the 2.0 lsj parts, i dont think the motor is as weak as some think but i still will do certain mods to be safe. i know how i am and ill probably end up wanting to play some more after i get used to the power, so id might as well build up the engine somewhat to hold the power nice and safely. once i get a quote on how much all the parts will cost me, that will decide how much work ill be able to do when its time.

another thing i like about this setup is i can go straight turbo in the future if i wanted to.
another question though, if i get forged pistons at a certain compression wont that throw off the tune when i get it from hahn?, as far as im concerned hahns kit is tuned assuming your on a stock motor no? another thing is if im using a specific piston for this setup what will happen if i decide to go straight turbo later or something else, does that mean ill have to change pistons again?

Director of GM Sport Compact Race department suggest I change Pistons above 300 which is my Goal After HIN. Adding Bates Cams, springs, Stage 3 Duel pass Intercooler, 50 Shot with GMs algarithem for CPU. Head Work Exh. Side. How Much boost will it produce combined

and thats pretty good if srt-4's are running that well in the quarter, do they have slicks though? or street tires?

Well someone should put this kit on their stock pistons and tell me how it goes and why the hell would you lower compression put the same compression in there 9.5.1 or something like that. That way when you go to tune the bitch it won't be that difficult. I think this is the way to go unless someone comes out with a blower swap. Then its over for everyone on the road. 400hp and 400tq in a blown 4 banger All I could say is wow.
