I was considering getting the same kit. I figured if I could sell my manifold, downpipe, and Intake I wouldn't be spending too much out of pocket. But as of this morning MAP doesn't have any 5858 BB in stock, only JB. I know transient response will be better with the BB, but how much better will spool be?
Also why did you pick the SS housing?

the non-ss housings have been known to fail under track use.
as far as bb vs jb, I personally would never get a large frame turbo without bb, mainly because of response.
i picked the SS housing because it's stronger and deals with heat better, both of which I need for track use.

So little change of plans. Got a killer deal on a MHI-18k from Cobb Tuning, they were selling them at a pretty good discount and it was too good to pass up. The MAP V band 5858 kit was tempting but seeing as I already have the MAP cast stock replacement manifold and 02 dump/downpipe I figured this would just be easier. Hoping to make 450/400 and having MHI reliability.
I wasp my stating cause in two previous messages I was saying how your purchase of the MAP V band kit convinced me to consider getting one as well. Almost pulled the trigger. Not trying to crash your party
On another note, that 5858 is going to make your car a monster Brian. Good bet it'll make 450whp and very low "track-safe" boost levels on E. I hope your brakes are up for it. My car makes ~430whp on the 23psi-24psi track tune. You'll have a similar flowing compressor, but with much less back pressure.

Then 500whp+ for the street when I'm feeling stupid.
If you get a good port job on the head (cough English Racing cough), she'll make 600ish for the street.
