After a ton of money and time the bottom line is that all the crap under the hood of my 89' mazda b2200 is a bunch of crap that is not worth fixing. I have had a lot of exp. with doing weber carb swaps on Samurais and know they are great. Looking back now if I was smart I would have just taken the money I put into this little part and that little part and ALL the time and just put it into a weber and header and got rid of all the emissions stuff right away. I would still say do the easy cheap stuff like plugs, wires, cap rotor and such for sure but behond that, good luck!! I HIGHLY RECOMMEND IF YOUR MAZDA TRUCK RUNS POOR JUST INVEST AND GO THE RIGHT WAY THE FIRST TIME!! GET A WEBER 32/36 AND HEADER, IT IS SOOOO MUCH EASIER!!

 

The webers also run great on VW bugs too!

 

What do you think I am going to do with my '87 B2000? (Nikki carb is current being nursed along until I can replace it)

Next tax return she's gettin a weber (though a buddy of mine has a holley 5200 with adapter plate from an early ranger, thats already jetted to run up a 2.3 Liter) and a header too.
