so i have been messing around with the computer program for a bit building my dream 383 stroker engine and i started thinking to my self "why not add the LSJ engine into my program. but since im not really familiar with the crazy fuel injection concept cos im still into carburetors and i spent like an hour finding the stock specs for the 2.0 LSJ for the 07 cobalt SS/SC and couldnt find em all. i was wondering if one of yous could help. ive had my 07 since feb 07 but i havnt had the cajones to do anything to it while its still under warranty. plus a 2.0 engine producing as much ponies as a 350 engine still boggles my mind. i have the bore and stroke, and compression ration. i need the intake and exhaust valve specs, and camshaft specs. maybe one of yous knows where i can download the 2003dyno file for the LSJ. sorry for the rambling. i love this website i just wish i could learn it all in a day and go put it into my car. any help will be fine thanks ><

 

one question how is the compresion a 9.2-1 on a lnf and it a 9.5-1 on a lsj and still have the same stroke and bore?

 

Different piston height ("Shorter"), mounted on the same rods = larger combustion chamber volume with identical stroke and bore. Same displacement with lower compression.

 

yea i felt like an idiot after asking that q oh well

 

There is a ecotec carb intake manifold.
