get ya a HX 35 turbo off a 98.5-2002 manual tranny truck and ya can get more air and at 32-34 psi

30 sounds about right with minor pump mods and PODs. Those are pretty much the numbers I've been reading. I haven't installed my gauges yet (that I bought a year and a half ago) since I've been moving. Hopefully in a few months I can tell you what I'm putting out.

The H1C on a 93 has about the same compressor as an HX35. The HX35 has a restrictive 12CM turbine housing. If I was in your shoes with a 93 dodge and stock turbo I'd dump the huge exhaust housing and go to an aftermarket 14 or buy a cheap 16CM from a 4BT H1C and bolt it on.

The H1C's are cheap, good turbos.

The '93 H1C had a 18cm housing with a max boost of 15-18. The 94 and 95 WH1C had a 12cm as well as the HX35's 12cm.

That was my point, the wh1c and hx35 are essentially the same thing.
