32/36 weber carb z20

What do all you guys reckon about fitting a 32/36 weber carby to a 1991 d21 navara with the z20 engine? What kind of improvements/gains are there? Are they worth it? The z20 has a full 2" exhaust with extractors with a lukey muffler

Thanks

That's a nice little Carby. Since you have extractors and a more free flowing exhaust it may be of some benefit. You will need an adaptor plate and a few other bits of hardware to sort out the throttle. Proably a choke cable to if your going to run one. It would be of some benefit to port match the face where the plate and inlet manifold mate but probably not necessary to open up the manifold to the same size as the base of the carb as it's unlikely the engine would have greater flow than the opening in the manifold now. You may have to jet the carb correctly but easier with the Weber than the standard Hitachi. Who knows, but it maybe good straight out of the box. Ideally you will need or rather take it to a workshop with a 4 gas exhaust analyser to check and or correctly jet otherwise it's very hit and miss.

It's a full kit you can buy off eBay with adaptor plate and throttle linkages and it's already been jetted and stuff

excellent carbie. variants of this carbie came out standard on 2l escorts up to 4.1l fords, and probably a bunch of other pre injection era cars . i've had one for years, which has been on a datsun 1200, nissan L and Z series motors and early 6 cyl. commodores. very easy to tune and maked the cars run heaps better, as they run a mechanical secondary butterfly

probably work ok but fuel usage may go up.
especially as weber is vac fuel off not electric like most jap engines are.
the webers tend to run on if you tune the idle really lean like factory carbs.
