They have so called bad version motors I believe. I have heard that they cant handle boost and wont make much power, bad ports. Cant say for sure how much power they can handle as stock, but I would say max 250...

It's oil cooled only.

Mine popped at about 250hp.

Might want to see what Ade (TiddlesRX7) is running as I know he's done a lot of mods (IC, Apexi ECU, Exhaust, Intake,etc) and still runs the stock turbo.

I believe that the earlier S4 turbos could not handle the same power as the later S5 ones. My S5 one is running circa 300bhp probably a touch under as we couldn't get enough fuel through the standard injectors when mapping it. I believe they are good upto around 320 BHP but that is maxed out. And as already mentioned, they are oil cooled.

Turbo is oil cooled, max HP you can run for any period of time is about 270-80 on the standard parts - but obviously wear is increased.

250-60 is a sensible upper limit on stock parts, transforms the car and doesn't tend to burst anything more than the clutch.
