WHat is the process for removing the smog pump system on an 86 GT? What are the pros/cons of this mod? Any input would be most appreciated. Thanks.

 

cons:makes your car ILLEGAL for street use
Pros: i think u gain like 5hp or some stupid thing

BTW, welcome to the site and do u have pictures of your 86? I love that style!!

 

I've never done it and don't know anyone who has but I don't think it would be too difficult to achieve. The hardest (most time consuming) part might be taking all the air tubes off but I really don't know. Lots of aftermarket companies make an eliminator kit that gives you a nice looking idler pulley and prolly instructions.

Pros would be increase in power, slight weight loss.
Cons would be emissions-illegal in most states, might cause a back-fire condition since no more fresh air would be pumped into the cats.

 

check your local restrictions and if you can get away with not having it then just bypass it and leave it there but unhook the hoses. That is what is done to ours. Id like to take it off but I dont know if it will pass since ive heard that all original equipment must be on the car but it will pass without cats. Some states, like NC, only require you to have emissions testing on OBD II (1996-2006+) models and anything earlier can run with no cats (and possibly other things not working). THey just have to pass a safety test.

 

Catalytic convertors are required on all 1974-present vehicles under federal law. So even if your state says you don't need them you still do to be legal with the feds. I'm told the fine for removing working cats is 10,000 bucks per cat.
