What whp and what spool can I expect form a Holset,WH1C who came from of a Cummins diesel 1994 Dodge Ram 2500 , on a h22a1 forge with a port and polish head, cause may be i have a deal on it

1600cc fuel injected mivec 4g92 engine
forged stock bore 4g93 wiseco pistons
stock head and gasket
acl mains and cons
stock cams
xs power ramhorn b16 manifold modified for the mitsubishi 4g92 engine
tial 38mm waste gate
hallman mbc
780cc precision injectors
megasquirt 1 v3
according to datalogs car makes positive pressure in 1st gear from 3800 rpm and 1st gear gives around 9 psi

Finally bought myself a HY35. Found it on Cumminsforum, lol. Definitely not bad at all, I'm excited to run it. Took the housings off the other day, wheels look bueno, so I'm going to clean everything up, weld the WG flapper, and slap it back together. Here she is in all her glory:

I have no idea what is all over the compressor:

wondering if a h1c is enough or if i should get a hx35. anyone using the h1c. lookin to make around 350 hp on a stock internal ls vtec with arp rod bolts and head studs. been looking for a wile and keep finding the h1c cheap. originally i was looking for a hx35
if shooting just for 350 go with hy35 great sreet turbo, or all around turbo at that
thanks i actually just picked up a hx35 for a good price. going to try that for now if its too big i guess ill try and find a hy35. not really worried about the spool time mostly track and weekend driver.
I would also like to know what size oil feed restrictor most are using. I would really like to hear from those that have an oil pressure gauge at the turbo. What kind of pressure have you seen with what oil restrictor size?
i would also like to see what people are using as a restrictor. i have read through alot of these pages and some people say use on some say you dont need one but no one ever says what size restrictor or what pressures they are getting.
which turbo is that, looks like h1c, ne way i just gat hx35 i have a spa top mount, people,with hx35 what other exhaust housing is there for the hx35,when i took off the wastegate acuator all that mounting point for acuator is ugly, i either want to grind off or find a replacement, was thinking bout the h1c housing cause its nice and smooth, ne suggestions, my reasons are because of my top mount, i know the 14cm housing spools great on b-series just look like **** when running top mount?
I finally installed the HX35 in my EG, I build a selfmade oil restrictor out of a wheel bolt from a VW weldened with a 1/8" fitting for the oilfeed. Works perfectly. Get a tune this week. The spool sound scares me^^ Love it.
Does anyone know if u can change exhaust housings hy35 9cm to he341 8cm? I have hy35 9cm now and if i can put he341 in that exhaust housing i dont need to make new downpipe..
