I think as you do research you will see 300 very to be more common than you think. I dont know what other forums you visit. And not to knock this one, but this is one of the smaller ones. There are Scion forums out there where everyday someone new is boosting their ride. From the 240HP rides to the 500 HP rides, all street car personal owned. ( i can post examples if you wish)

I know of about 7-8 tCs in the virginia area that are pushing the 300WHP envelope DAILY with nothing but a turbo kit, and yes I guess there are supporting mods. You need an exhuast that can flow that.

But I still consider that just slapping a turbo on, because an Exhuast is a given when upgrading to a turbo.

The greddy kit will get you in the 265-275 range, add in an exhuast and you are close to the 300 mark.

Zpi (sucks) stage 1 gets you to 300, easily.
Dezod S1 with the dezod exhuast hits 300.
Turbonetics with exhuast hits around 290.
Turbo toyotas around 275 ish with exhuast.
And there are more out there.

And everyone aroudn here runs them daily.
