If i get a smog pump eliminator do i need to remove anything else?loosen or remove the bolt(9)that goes thru the adjusting bracket and into the smog pump, its the one facing the radiator
down by the motor mount, loose the long bolt(12), it needs a wrench on both ends or it will just spin
thats it, it may need a bit of a pry to get it to move. Chances are its seized up, you can gut the pump, replace the pump or get a smog pump eliminator kit(its just a pulley) The same belt also turns the waterpump.......so you need to have something there.
The smog pump can be swapped with an idler pulley. Done.
The EGR valve can be disconnected or removed, but the distributor will have to be recurved to retard the timing.
The cat can be replaced with a straight pipe if you want a noisy, stinky exhaust with a little less back pressure.
All the other things are just asthetics. You won't get better power or mpg. Just less clutter in the engine bay.
Some items that can go under the category of "smog" parts are good things to keep and shouldn't be removed.
HAC system, HAI system, Choke Opener operation, EVAP system, HIC valve, Distributor venting VCV.
All those yards of vacuum hoses in the engine bay are not evil. Most of them them help the engine run better.
