Just bought a speed3

[o3clipsegts]

Whats up guys just traded my 420whp STI for a new Mazdaspeed3.Im wondering how strong these motors are. I never had any problems with my STI at that power level. What hp or psi can the stock block and tranny handle. I love the car so far.

350 seems to be the general consensus before having to go forged. Try searching and reading around, there are plenty of threads about this.

if he came from a 420whp sti, i dont think he would be asking "what psi can a motor handle"


seriously

not to mention gasoline powered cars don't use motors they use engines motors are for electronics buddy, and idk how many psi my windows can handle
