I made a similar switch but to a 2800 5disc vig with similar setup and turbo as you and it spools better than my stocker did with my D5. It's a night and day difference for me and a GREAT street setup. I can slam 20+psi from a roll almost instantly and fry tires at anything 30mph or less.
I had to re-tune the alky though and turn it on sooner to keep up with the new spool characteristics. I wasn't able to get any more than 4 maybe 5psi on the brakes from the D5 and my 44 but now I'm only limited by my brakes. And my 60's are good with little to no launch boost. It just comes up that fast to still 60' well.
