ecotec swap (Page 4/98)

i forgot that i had to make a slight mod to the cradle to allow the ac compressor to fit .i did not reweld this area because with my setup this crossmember no longer carries weight ,it just acts as a spreader .my ac does not work right now but i hope to get it going this winter.the ecotec compressor was damaged by the wreckers when they pulled the engine.

i have been working on getting the fiero ignition switch to turn on the ecotec .i spliced onto the purple wire in the engine compartment and extended it to the eco starter.now the fiero key will turn over the eco.i added three relays to break the hot voltages that i found on the cavalier ignition switch .the plan is that when the fiero key is switched on the relays pull in and i can just leave the cavalier switch in the on position and use the fiero key to turn the car on and off.but i have run into a snag.when the fiero key is turned on ,it seems to cut out the key controlled accesorie feeds .so when i turn the fiero key the car cranks but doesent start .since i dont want to use a switch to turn on and off the relays ,i am going to add a second feed to the relay coils from the solinoid pull in wire.the accessorie feed will remain and take care of relay coil voltage once the switch is off . i can still start the car right now by turning the fiero key on and then cranking with the cavalier key ,but the goal is to only use the fiero key.

wire to eco starter

well adding the extra wire to the relay feed turned out to be not well thought out.i forgot that there would be a backfeed to the starter solinoid from the relay feed.so after i started it i searched in vain for a rattle that i didnt have before .that was the starter not disengaging and now i think i fried my starter.all this to avoid using a 3.00 rocker switch .oh well ,live and learn.

Good work. Is that the 2.2 or 2.4? I saw a 2.2 advetized today out a 2003 (I think) Cav for only 200 bucks.

my eco is a 2.2 .they go pretty cheap ,there really isnt a huge market for replacement ecotecs.

i have been working on my new exhaust system and i figured out that a 50 cent diode would have saved my starter .new one cost 270.00 cdn no one rebuilds these yet apparently.some more pics

No Ecotecs here, a shop I deliver parts to replaced an ecotec, and the cheapest one they could find was $1300, and that was just a long block, without an oilpan and exhaust manifold.

mine cost me 1000.00 and came with 5 speed
entire cars wiring harness
steering collum with ignition and key
shifter and cables
entire breather assembly
cavalier axle assembly.
found lots of ecotecs for around 500.00 for an entire moter without harness and accesories
got mine from bell city in brantford ontario.lots of bad drivers in ontario =lots of wrecked cavaliers
