I currently have a DSM T25 .48/.49 and the cheap e-cracking mani/dp setup.
I'm pretty happy with everything @11 psi and love the spool, but it's time to switch to something reliable and solid for track days. Since I can't find a good mani/dp for DSM flanged for decent prices, I think I'm going with the begi mani (for standard T25), new turbo, and dp.
I've tried to search for answers to these questions, but haven't been able to find much, if any. Questions are: Begi dp, or FM cast & SS dp? Reliability? If Begi, is the divorced gasses worth the $, or go with the S kit dp? How much more performance in the divorced gasses design?
I'm pretty sure I want .80/.64 T25, but should I go with SR20 S13 T25, or spend the $$$ on the GT2554 (and get it from begi since they mod theirs)? I think everything is the same (trim, a/r, etc.) between the two, except for BB, and new vs. used). How much better spool on the BB vs journal bearings? How much spool would I be losing compared to the .48/.49 DSM?
Just want a cost effective solution. I don't think I'll be going to external wg either, or looking for anything more than 230whp in the end.
