how much psi can we boost on stock motor?

 

eleventy billion.

Stock turbo is already maxed out. leave the boost alone.

 

so..... if i want to up the boost to eleventy - one billion i have to upgrade the turbo?

 

yup

 

and if you want to reach 30 billion, get forged internals and valves and all that fun stuff.

i tihnk i saw a kit for the MS3. its a larger turbo, and piping i believe. i think ups the power to 320 whp. all this for i think $1000 cdn

 

320whp on a MS3 is nothing more than an exhaust and piggyback away.

full catless exhaust, CAI and piggyback and you've got 300-320whp..

very fun cars but leave the turbo alone unless you're prepared to pay.

 

i thought that they where having tuning issues with these? so piggybacks like safc and such are working?

 

there, i found the link.
and it makes around 320 whp, with stock everything else.
so with adding a CAI and catback and piggyback, you'd be pushing i dunno, ~350whp?

Well using the Apexi SAFC on a mazda is just a joke.. our ECUs are way too smart for it.

Something like an XEDE plug and play ecu though.. now we're talkin

 

or electromotove full stand alone lol
