What are the best performance upgrades for speed 3? What kind of power can I expect from them?

 

you have a lot of options to increase power. theres the intake, exhaust, intercooler, turbo, headers, etc. depends on how you want to start and if you dont mind voiding "warranty". theres alot of aftermarket parts taht mazda offers and you wont compromise any warranty. wat exactly are you lookin for in terms of power? do you have a budget?if you have no budget, can i get some money for an exhaust? lol j/k..

 

Kev79 Have you even driven a stock one yet?

SST, Man, I think you PEGGED this one right out of the box.

All Right!!

 

lol, ifa stock speed3 isnt fast enough,
try some of the following mods.

FULL turboback exhaust. (downpipe + catback)
cold air intake
turbo upgrade
larger top mount intercooler, or a front mount intercooler
blow off valves

shall i continue?

 

oh, and i'd expect those mods, all together, to yeild around 350 - 400 whp.
but thats just a guess.
i've seen dyno sheets from speed3's with turbo backs and an intake making about 280whp
