Default possible gain?

i bought another turbo from one of my buddies for $40. it is non wastegated, the tag on the side says H1C, and the compressor housing looks the same size as mine. the inlet is smaller and where the intercooler boot hooks up is smaller than on my turbo, but the exhaust housing is bigger than mine. i was just wonderin if i had anything to gain by switching the exhaust wheel n housing? is this turbo really worth anything to me?


i have the serial number if its any help

h1c were used on first gen 12 valves and in 94 for the p pump engines. i dont think youd gain anything at all the h1c's were not very efficient turbos. but i do not know 100%.

I know for a fact you won't gain anything but slower spool and higher exhaust temps.

WH1C is a decent turbo and is the same size wise as a HX35 on the compressor side.
To use it though you will need to remove the large exhaust housing(usually a 18cm or a 21cm) and install a smaller one.

Actually, an H1C makes a pretty good turbo for a smallblock, not-too-radical v8 gasser. I know a few guys who run H1C's with 302ci Fords. I may or may not have sold my old H1C to them for just that reason...
