I've got a Pace twin core intercooler on mine and had the car chipped about 3 months ago the boost peaks at 14psi and holds at 12psi at 170bhp and 190ft and haven't had a problem with the standard turbo and the temperture is fine so they must be more than ok for that kind of boost but I just bought a Radtec intercooler a few weeks ago which is getting fitted along with the Airtec turbo cooler so my Pace will be up for sale soon on Ebay if any one is interested.
