I have a HT3B off a N14 Cummins - Would it be a good turbo to stack with my HTB2 62/14 turbo?

Thanks

 

Depending on the exhaust housing , that would be a good turbo to make a set of compounds out of.

 

What about the exhaust housing?

 

23 or 26cm is the most used.

 

How do I tell what size I have?

 

Clean up down in the inlet on the exhaust housing, and it should tell you what size. It will just be a bog number engraved into the housing, but it will probably be packed with soot till you take a wire brush and clean it out.

I looked at the exhaust inlet side this mourning and found a number "20" stamped in it. Is this to small? Also, I heard somewhere that it's better to have one big open hole on the Ex inlet rather than a split design (Mine is a split design). Is there any truth to this? Thanks for the help.

Is a 20cm ex inlet to small?

 

it would work fine for a set of towing twins. it would choke it on the big end for drag racing or pulling.i bet it would be fine to 550 rwhp or so.

 

That's great news! All I'm looking for is in the 500-550 HP range anyways. With some Mach 4.5's or 5's I'd be set up.

Does anyone think I'd have head gasket issues with just having studs and no o-rings on the head in that HP range? Thanks

I cant see a 20cm housing supporting 550 RWHP. It will be way to hot. I've got a 26 with just over 500 and it gets warm. I could see somewhere in the 450 range.

 

I would get a BHT-3b/26 for the primary, there cheap as turbos goes. It should work well with the secondary turbo that you've listed. It will work well with bigger mach injectors. I would go out on a limb and state that your existing turbo is to small for your existing turbo, but saying that you would have decent spool-ups. Your existing turbo should almost be able to run the mach 4. If you want to run a fueling box you will max out your existing turbo and have egt issues.

 

Can the exhaust housing be changed out on these HT3B turbos easily? I'd hate to have pay money for another turbo, maybe I'll just have to match injectors with the turbos I have. How big could I go? Thanks
