I am looking to do the H6 swap into my 05 Legacy this coming year. With the help of my brother's pipe fabrication, I can create a custom turbo manifold to run a precision PTE 6265. We are also looking into fabricating an intake manifold as well. Once I finally have everything in place, I'll start a new build thread to show the motor build and the swap. I've been skimming through a few pages of this thread and I still have a few questions before I get started with this swap.
1. Is the EZ30 a PITA to tune? Or should I go with the EG33?
2. As far as the radiator goes, would I be able to get away with a Mishimoto radiator with single fan, or should I be looking into a dual fan assembly?
I know there will be plenty of questions that will come up, but are there any major complications between the 2 engines?
