Just curious...but are you dead set on brand new parts? I got my PI heads and Intake on Ebay for under $500.00 and they had less than 16,000miles on them.....just another alternative.
I'm gonna have to be one of those guys that says otherwise. My kit uses an Eaton, which has proven to be stone reliable in many applications, for years. This is why Ford can build vehicles like the '89-'95Thunderbird SC/Cougar XR-7, '03-04 SVT Cobra and '99-02 Lightnings. Several other manufacturers use the Eaton set up as well, like GM and Mercedes. I agree, if someone starts getting greedy with the boost, there's a good chance that it's going to lead to problems, but otherwise, I wouldn't hesitate going the positive displacement blower route, for a second.
