emissions

hi i have a question about my smog control systems. i have an 84 12a car, my question is what can be removed without hurting the engine.

[TOOL]

You can remove the lot. It won't "hurt" your engine, but it might mean you can't pass a smog test.

Our cars in the UK are exempt and only require a visual smoke check.

i am in the us and my car is right at 30 so i do not have to have any form of inspection.

[TOOL]

Rip it all out then, air pump, rats nest, etc.

Fit some headers to release 10-15hp for a start and go from there.

[tj19985]

but what is the purpose of the air pump?

[TOOL]

It put fresh air into the eaxhaust to burn the remaining unburnt fuel in the thermal reactor.

I've got motors pre emissions and they had "cast headers" for lack of a better description.

Totally unecessary equipment.

Find the instruction sheets on here for removal of the air pump and reactor.

Probably 98% of UK cars now run with a standard type of exhaust, usually stainless steel. The instruction sheets have been prepared by the stainless exhaust makers and include reset data for the Nikki carb.
