Outer Limits 4x4 Board

Yep two questions.

First: Do Sierras carburated engines come with catalytic converter??

Second: Can someone tell me whats the brand of the original carburator in the Sierras???

Thanks

Will

Yes

Asin i think

Not all sierras that ran unleaded had a cat. Some post 1986 N/Ts never had a cat. All wide tracks had a cat.
Grimbos trayback never had a cat (1987) as it was a commercial vehicle and did not have to comply to ADR's for passenger cars.

Could be aisin. Vitara carbs DEFINITELY have a mikuni stamp onthem.

Ive got an early 88 WT, and found out that it is missing the cat, looks like they have chucked on an early model exhaust, and it passed a road worthy . Easy way to tell if it meant to have a cat or not is to look for the heat shield that is just behind the engine.
