Anybody know if an eco from a suturn Vue is the same as a cavy? I'm prety sure, but not 100%.
yes, the only differences are cosmetic. Saturn had the motor back in 2000, so 2000-2002 are the same, and 2003-2005+ will be the same. fuel injector, fuel rail changes as I recall.
Some parts on the ecotec engines are different...
00-03 "L" IM: 24409050
00-04 Vue IM: 24467211 (same for 03-04 Ion)
05-06 Vue IM: 12587202 (same for 05 Ion)
00-03 "L" auto TB: 17099120
00-03 "L" man TB: 17113709
02-06 Vue TB: 12568796 (same for 05 Ion)
03-04 Ion TB: 17202005
00-01 "L" Injector: 12565473
02-03 "L" : 12574282
02-05 Vue : 12575947 (same for 03-04 Ion)
06 Vue : 12582704 (same for 05 Ion)
00-04 "L" rail: 12574291
02-03 Vue rail: 12575952 (same for 03 Ion)
04-05 Vue rail: 12586713 (same for 04 Ion)
06 Vue rail: 12596245
05 Ion rail: 12582689
Also, the Vue had a VTi transmission. On those the flexplates are different than Ion. Same if normal auto trans.
06 Vue has different water pump
i have set my ecotec up in the back of a 9" stretched fiero on a t 125 fiero transmission with a adapter plate now ,i am down to the wiring i have a 2003 cavalier harness i went to the dealership today an got a ecu computer plug pin out wiring diagram for the wiring , i want to find out what is in the gauge cluster that will keep the engine from starting so i can jump it out or send the correct voltage to it ,to make it happy ,i hope their are some experts here ,i plan on riding in 4 weeks so i will share info an i hope you will too ,if you want to see pictures go to :

i also found a place to reflash the ecu , they increase air / fuel ratio turn the governor off an increase the RPM limiter to 6450 rpm ,after this rpm you would float a valve ,why did GM put the rpm limiter on when the engine was still making power ,so you would go to the next size engine, ( money for them ), if one is avalible ,reflashing the ecu NET 170HP AN 155 foot pound of torque this is a stock internal engine with a larger diameter exhaust header ,this is for normal driving ,daily use
