It's difficult to make an ultimate pickup because of the way the older EJ20 upper baffle really
crowds the pickup. I'm making some "Rugedized" units for a couple of Cosworth applications, since they provide an OEM pickup with thier reworked OEM pan. And we all know by now how the OEM pickups fail.
You can find info on the Rugedized pickups HERE.
Read post 36, the one with all the pictures in it, to see why the STi pan is better.
