Which Schwitzer 4LHR would best match the NHC-250?

I want to add a pulse manifold and Schwitzer 4LHR to my stock engined M813 and I can't seem to find any technical info on the various 4LHR models such as 4LHR-733, -743, -773, etc. For you turbo guys out there which one would have the best wheel sizes to accentuate a 290-325 HP level without being overly massive & slow to spool?

Stick with a ht3b. The 4LHRs are a bigger inlet housing than the 3b so they spool slower. They are rated around 350hp.

It looks like Borg Warner lists about 20 flavors of HT3B probably with different wheel sizes / cartridges.

I came across a listing for a BHT3B that they say is ported for pressure spike reduction that plays nice with non auto-lash jakes. I think I'll look into this one a bit more.

Wes, do you (or any other members here) have any experience with the BHT3B turbos? It looks like they're the same as an HT3B but with the map width enhancement groove. Do they have any other advantages?

I have one as a spare to my HT4B

26lbs of boost with a #5 button and 250 rp.

HT60 is an upgrade of the HT3B but not by much.

The 3 series and HT60 are good to 600hp. You will want the most air you can get into it.
