Guys, what do you think about hanging an ht3b under my he351 rather than an s400? I found a guy selling a turbo listed as a "Garrett HT3B" but i was under the impession that holeset manufactured it? Quick replies appreciated I wanna make a move before its gone.

This is the description on his posting thanks

Garret HT3B turbocharger is in very good condition, spins freely and does not seem to have much if any play, I believe it came off of a Cummins NTC engine. I bought this turbo to build a twin turbo setup for my dodge truck but after I got the turbo I lost interest.

The tag on the housing reads:

Garrett Remanufactured
Model:HT3B
P/N:144404-9000
S/N:BJM0001

Ht3b's were made by a number of mfg's including garrett. I had a garrett bht3b at one point.

Those are older tech turbos and the advice here is you will do much better with a s400.

The ht3b is a very reliable unit. It is not the most responsive though. Unless it is next to free on cost, I'd pass.

300 bucks?

Also, I should mention this is a reverse direction turbo. Meaning you would have to find custom piping (can't use s400 piping) and may cost you more in the long run.

My vote is for the S400. There is probably some kind of plumbing out there for the ht3b, but my guess is that you will be in the fab business rally fast.

ok so ill go with the s400, excuse my ignorance but is there any specific details i should look for when purchasing one? Are there diff exhaust housing sizes and compressor wheel sizes? Or will i be safe finding an s400 and picking it up? thanks. Btw all piping including hot and cold pipes will be done by me at the shop so its gnna be a project thanks

An s475 is an ideal size.

The EH range from 1.25 to 1.32 is adequate. I am going off the top of my head... Those numbers are not the exact ones.

soulzoo thanks for the replies, i am starting to gather everything for the build and want to know opinions on wether or not to purchase a new manifold. I believe i will but want to know wether it is worth buying or not. Also is there a specific manifold i will need for the he351/s400ors475 build. I keep seeing diff flange names and numbers? thanks again im sure ill have many more questions to come

You have to buy a new manifold. Look at a number of other twin setups closely before attempting to do this yourself. There are a lot of little details to pay attention to. It is more than welding a couple of pipes together.
The manifold to use is a 2nd gen t-3 turned upside down. There are a number of good choices.

475 is the way to go, I love it

I have a 2nd gen stock manifold in the garage if you are interested. PM me
