05 sti limits
 

Hi

Im currently building my widetrack 2005 sti. Ill be using a 2.1 cdb and borg efr 7670 turbo. Hoping for 550-600bhp.

My question is.. at what point will i need to start upgrading diffs, prop, drive shafts ect?

Any help would be really appreciated

i think it,ll depends on the sort of driving you do really. harrrd drag launches will reguarly snap driveshafts ,with road driving its all pretty well lasted and proven into the 600s- changing clutch plates can get expensive though lol.

be really interested to hear how the B&W turbo drives, sounds a good upgrade from my current sc54(520 vpower 560 meth map) turbo. rich from zen reckoned it was a lot of turbo for the money:p

will need an ecu at that power level as well, syvecs is the way to go

Much less likely to snap driveshafts if it's a widetrack. They are much sturdier, with bigger hubs.

Ive got an alcatek ecu for the build. I was hoping the running gear would take the power. I suppose theres only one way to find out eh. Thanks guys
