GM 2.2 Ecotec Limits and Upgrades, based on info from GM's Sport Compact Performance Build Book.

 

wow great find, thanks

 

good thing i have most of that stuff already checked off. the only thing im missing is the nitrous kit and the alpine tubro kit to get me to 400hp

 

Time for a real noob question... but whats it all mean?

Please dont rip me apart too badly... I am just getting into all of this

 

It's a chart that was made by the poster consolidating all of the horsepower limitations of various components. Nothing more, no mysteries.

 

Not only that but it has numerous errors and false data (Oldpro=1 post??) and seems to promote various "upgrade" kits and companies that aren't even IN the build book (or vendors HERE for that matter)
Wop

 

actually. the build guide does referance Wiseco pistons, egale rods, ferrea valves and springs, and the bates valves and springs. there is an updated/edited build guide out that has these parts in there. the alpine isnt listed in it, they recomend Hahns ecotec turbo with fuel managment system. and you can get all of the engine components are turbotechracing.com which is a supporting vendor. also where i bought all my engine internals.

 

+1 i was just thinking "holy crap alpine got GM to put them in the build book??"

related to the post... where did u get that 2.5" is good to 300hp and no higher? just curious.

 

Guys, relax. This guy just made a chart on his own (that is not a GM publication) using information he interprolated from the book. No biggie.

 

I'm new to this I bought a cobalt from Marty ladwig he's a two time national champion fwd class anyway the car has only 15 miles on it a full roll cage and a new 2.2l installed but not wired (all electronics were stripped) Fuel cell in the trunk exc my question is I have no electronics with the turbo kit I have and I'm wondering if there's a one stop device to manage all aspect's of adding a turbo to a non-turbo car?

 

Standalone ecu like megasquirt

 

Stock Pistons wont hold over 250hp long. There just too weak and a bad pull will end them easy.

I've ran a stock motor with a intake and exhaust with a 100 wet kit no problems
