Mike - I've heard some good things about the Hybrid intercoolers. The guy that made mine was saying that they've seen tests of a few different bar and plate cores to see which cores lost pressure over a period of time. Apparently, after something like 30 seconds, while the Hybrid cores were still holding 30psi, genuine Garrett cores had lost around 4psi through tiny pinholes / manufacturing flaws !!!
I know that Mark at Western Suburbs (my guy) said they were really good value for money - much cheaper than Garrett cores. The only limitatoin at the time was the fact that they didn't have many end tank shapes or tube sizing options at the time.

If you send them an email with an questions, make sure the email is addressed to Mark in the subject line . I haven't spoken to him for ages, so I hope he's still there. He was the brains behind the fabrication side of the business.
GO THE BOOST...... THE DARK SIDE JUST GOT DARKER !!!!!!!
