Default 350 WHP on my STi, do I need to upgrade the clutch?

Hi everyone,

I am going to have a larger turbo (FP Green) installed in my 04 STi next week. I was wondering whether my stock clutch will hold the 330-350WHP that I am expecting the green to make on my car. Any help or advice you can offer would be appreciated, thanks!

Ernie

Also wondering, though I bet a search would reveal the answers.

I tried doing a search and did find a couple of threads on the subject, but didnt find anyone sharing their actual experience on the STi with a car of this type of horsepower. hopefully someone will chime in soon.

As far as I know the stock clutch will hold that kind of power. Im putting a GT30R on my sti and I should be making 400 HP and Im planning on using the stock clutch till it burns up. But i should hold 350 no problem.

FWIW, I've got almost 21k on my car total. I've been running a GT30R (370whp) for the past 3k miles, and Stage 2 (290whp) for the 15k miles before that, all on the stock clutch. Zero problems so far, but I don't launch the car and I'm pretty smooth on shifts. Moreover, I've mentally put aside the money for a new clutch...along with a new built shortblock. Personally, I think it's a question of "when, not if."

My advice? Run the stocker until it dies...it might pleasantly surprise you.
