hmmm not seen that one yet... wonder how well it works and what it actually looks like (as that is definitely not it since we dont have a I-4 manifold ;) ). T67 sounds pretty big too, i know the T78s would do 700hp + on supras with the fuel upgrades and all... wonder how much hp you could expect from something like that?

well if you put it on the STi make sure to beef up the drivetrain... people are having problems stock let alone putting a bigger turbo on..

Give the STi to my wife????

I've actually ran a T67 on a WRX and I was not very impressed. Perhaps the housing size was not properly matched but I didn't get that much power and the laf was sizable. I made more power on a GT30R and had much faster spool up.

Who's having drivetrain problems stock?
I know of a guy in town (s/n on club wrx scottinal) that has snapped his drive shaft or his axel or something... stock... hes not the only one either. Very stick track or surface + hard launch = problems. Adding another 100+ hp = more problems. Definitely going to need to beef up the drivetrain if you wanna run a bigger turbo (unless you never do anything but runs from a roll of course).

there is a guy getting beefier axles (do a search) he broke one (pictures were posted), but his sole intentions are winning at the drag strip

i would like to hit 400hp+ too one day but i will keep boost low in 1st and no clutch drops.

I'd much rather snap an axle or fry a clutch then eat diff ring gears or blow trannys.

That seems like a safe trade-off if your gonna get on it at the dragstrip.

I didn't realize STis had axles designed to fail? What PSI or torque are they supposed to let go at?
