performance

i have a 86 b2000 with a 93 b2200 engine what a cheap upgrades to make more power

Really almost every Mazda engine modification is done for reliability rather than power. If you want to go faster you will need to do a motor swap.

You can installed a Weber carb and pacesetter header but i felt no performance gains rather than smoother idling and fuel economy improvements.

My bro rebuilt his engine and its pretty quick compared to the stock worn out motor... it was bored .30 over, has a bigger cam, lightened the fly wheel, solid lifter swap and then bolted on a weber carb and pace setter headers. Though going this route isnt exactly "cheap" or impressively fast but it's got enough power for a little mini truck.
Like Sask said, if you want performance your best bet would be to swap a better engine into your truck but unless you have a complete donor vehicle that can get pricey real fast.

what isnt faster than the stock 80 hp

a stock vw bug...
