What is the largest turbo I can run with a stock clutch on my 09 Cobalt SS?

The stock k04 with a tune lol. Anything more than that and you'll blow it soon enough.

Have a look some build threads, your first question should be what are you goals for power? The smartass response above comes from a guy with a little over 400TQ and HP running a S257

I mean he's kinda right tho. U can go through a stock clutch with a stock turbo depending on the tune.

Yo could probably get away with Z54 with a smooth boost ramp. I did all last season with my stock original clutch.

the stock K04 is arguably the hardest turbo on clutches and trans because the torque curve comes in so hard and low.
Torque is the enemy of drivetrain parts.
