This is my second choice for turbos.
I selected the GT35R for a fast spool.
As for the 'regrind' choice of cams: I will look at those that have a known history of performance. At this point I just don't want to be the test subject. After getting this project together and tuned on my dyno I will be in a better position to make grind change choices.
As for the cam gear to gear drive - Mercedes and BMW both have adjustable cam position drives (chain driven) and was thinking Subaru might as well.
The AEM would be able to control an adjustable cam timing set-up.
Thanks for all the comments and questions. Any input is great
