hi all im new here... i was wandering what is the stock hp on these and the gear ratio for the trans i will be using 2, and 3 gear. . my car is a 2002 sunfire with a ecotec and 5 speed ? any help would nice. i am also looking to get as much hp out of this as i can but still look stock .. and does any body know if it has a limited slip diff in it ?
i think they are 140hp stock i have a 02 as well and the first thing i did for extra hp was a cold air intake. it took a few days but it really started to up the hp and mine is a auto (which sucks) but it started to change the shift times so now it redlines in every gear. also look into a bigger throttleody stock is 52mm i think get one that is 72mm or under anything over 72mm suposuble lose power for everyday driving.
i think stock is actually 56mm,and i don't think you can safely bore it out more than 62mm,but don't quote me on any of that, lol,and yes stock hp is 140
