im looking to buy a holset hx 55 turbo for my 1994 3500 5 speed. the truck is mostly stock with a #0 plate and afc mods. it really dosnt smoke much at all i found this turbo for 400 bucks would it be a good turbo to run as a single charger? will it be slow to build boost with the fiew mods that i have? the exhaust housing is 19cm which the 1989-1993 went as high as a 21cm exhaust housing form what i am told? what do yall think about this turbo for a swap?
