Hello and Mazda Question!

Hello!

I am the proud new owner of a 91 Mazda B2200 Standard Cab Short Box 2WD Manual!

The truck needs a little maintenance work. The engine has a rebuilt head with 30,000 kilometers on it, 297K on the whole truck and engine. The truck has some rust but only surface, except the rear wheel wells in the truck box, which have holes, and rust holes in the side mirrors (never seen this before on a vehicle, rather amusing!)

I am curious as to what kind of work I can do to keep the engine running and alive? It is a carb engine, with the funkiest EGR/Preheat system I have ever seen (seriously Mazda, 3 huge pipes going across the engine to a massive air cleaner module with a spider's nest of vacuum hoses hidden underneath? WOW.

I have heard there is a relatively simple conversion kit to a Weber mechanical carb, any info on this or guides to do the work? I basically want to seriously clean up the engine bay, provide a little more power and not spend thousands (sadly, there is rust, not sure what to do about that yet...)

Any ideas would be helpful. Right now I'm just glad it runs, the heat works and defrosts and it shifts smooth as butter.

Welcome. The simple answer is that yes a Weber will make your truck look cleaner under the hood.

Where are you located? There are a few areas where a Weber is illegal for highway use, mainly California. I'm in GA and they just do a sniffer test on 25 and newer, so I'm fine.

Welcome!

To fix the bed I suggest replacing it, don't waste all that time and effort on sheet metal work unless you are the guy doing the work. To replace it you'll need to find a clean one which isn't easy but doable.

A weber swap is easy and provided it is legal (you don't have emissions testing) you'll definitely clean up your engine bay.

Keep her oiled and lubed and you'll be fine engine wise. Make sure you don't let her overheat, the heads HATE it!

There are other guys here in the 200 - 300K mile clubs so you'll be in good company.

One "rule" here, post pictures of your projects.

Im still rolling on 288k I just recently put a headgasket, waterpump, thermostat, timing belt and all pulleys on timing gear as the previous owner let it get hot and blew headgasket. I drive it 60 miles each day. I have the weber and pacesetter header which cleans up the hood a ton and Im very happy with it other than when I turn it off it deisels but Ill be fixing that soon enough but my truck was neglected motor wise and the thing still is running strong. I couldnt have gotten a better truck so mileage is meaning nothing to these trucks if you dont neglect them.

Thanks for the suggestions and help!

I'm in Alberta, last bastion of the Wild West, land of no emission testing (it floats down to California on the winds, and becomes that paint peeling rain you guys love!)

I'll see if I can find another wholesome short box... not easy up here, winters are very harsh. We'll see though.

Also, that link provided for the Weber carb swap is for the B2000, is it the same kit and same parts for the B2200?

Thanks!

+1 for no emissions testing...
I removed the double cats on mine.

Still learning, but where can I buy a header to work with the Weber carb? Also, where are the 2 cats located?

You'd think an 85HP motor would be bogged down enough without those POS!

my header was bought thru jcwhitney. eBay is probably the cheapest tho. the header gets rid of the exhaust egr crap. you know those exhaust hoses going to the carb... the cats are right behind the manifold straight beneath the drivers feet under truck. mine had two of them some sort of precat and then a cat. converter. I removed both of them. My truck sounds good and I have a cheap O'Reilly raptor exhaust.
