I'm rebuilding a 92 W350 with an HC1 and what's an upgrade for it??? Any help would be great while I have it off the truck!!! Also I have an 91.5 W350 with an HC1? Is that the stock turbo for those?

 

there is a 60mm intake wheel and housing upgrade, runs about 250. I think Pure diesel power sells them among others. The problem is, for a little more you can get a better used turbo. If you have the 21cm^ exhaust housing, I wouldn't even mess with it. By the time you buy the smaller housing ($200) and the upgraded compressor wheel and housing (250) you could have bought a used HX35 or 351

 

I've had HX35's on 3 different trucks, don't like them for towing.

however i now have a 60mm with a 16cm housing on the exaust side and love it.
with the mods in my sig i feel like i'm in the 300-350hp range and can tow anything i hook to it with a max wide open EGT of 1250*

 

Well probly not going to change the housing's but also not sure on the size of the housings on it, it's a stock HC1 on a 92 Cab and Chassis if that help but i was interested in swaping out the compressor wheels? Where can i get one? And whats a better one? Its going to be used for towing. Not sure on how many blades is on mine now i can check it out monday when i get back in town

I might swap out the exhaust housing with a 16 cm $200 bucks aint bad

 

I to, swapped out the exhaust housing for a 16cm^

 

You can get a 16cm housing off e-bay for 169.00 free shipping for an H1C
and Gellett diesel has the 60mm upgrade, thats where i got mine.

 

What mm does the stock HC1 turbo have?

Whats better the 14 or the 16?

 

Depends on your fueling and what you want to use the truck for.

As far as the wheel goes, I think stock is 54mm

If your talkin about the 5 spd truck i would go with the 14, unless your gonna tow then the 16.

the smaller the exaust housing the quicker it will spool ......but.....also the smaller the hotter the EGT's will run when towing.

Well i'm gonna be towing with it and stock fuel might turn the screw up a little but thats about it and yeah its got the getrag 5speed
