Hello all.

About a week and a half ago I bought a turbo on a whim for my engine. I knew this turbo was a bit big, but I got it today.

The package was 61lbs, and came in a wooden box that i could only open with a powered drill.

I don't even know what kind of turbo it is, as I can't ID the casting or Assembly numbers.

Here's a few pics:











Looks like a divided T4 flange (hopefully)



Here's a few pics for comparison:



KA24 rod and piston inside the compressor inlet:



Turbo next to a tall degreaser can:




On top of a friend's K20A3:





I do intend on making this work on my 2.5L 1JZ-GTE. The turbo has a 6" inlet, 5" exhaust, and looks pretty decent. Doesnt have much side to side shaft play, and no in and out play. the shaft spins freely, and didn't bind anywhere.



I'm going to do a fair bit of custom modding for this to fit, but i think it can be done on a budget. Don't want to run more than 10-20psi with a quick-spool valve, for fear of compressor surge.

I got it for 145 plus shipping


Let me know what you think.

do you know the specs of the turbo to know if you are able to only run 10 psi range??

It's off Cummins truck. Nothing special.

Looks to be a holset hx55 or bigger, look at the holset tag on the compressor side and give back the info on what the tag says.

Ok the turbo you have a is ht3b, they run around a 23-28cm^2 housing, and suppose to be equal to a 76mm turbo, and support 700-800hp.

Nope, just assumed it would surge.

Lawls. When you deal with tiny turbos all the time, it's a big deal when you can fist an inlet pipe.

Great timing, As youw ere writing this, I found this out. When I get home, I'll find out what housing I have.

I feel much better about spooling this, since people are spooling T88s, which are larger, with a 1JZ. A bit laggy, but nothing to worry about. I think I could get this thing spooling by 4k with cams and a quick spool valve. I'll see if I can find a smaller housing in the meantime.

LOL it is a truck turbo.

I think you could switch out the exhaust housing with a hx40 I'm not too sure so you could spool it quick, but most of holset turbos spool very quick so you may be ok.

Some of the diesel guys have trouble spooling it, but their exhaust characteristics are completely different. I think it has a 32cm^2 housing. I think I may just block one side off permanently, or use a quickspool valve to get the desired result.

man i did not know you can put these on our cars.because at work we have a bunch of old diesel trucks with turbos on them doing nothing.

Thats a Holset HX50.

BFT!!

I pretty sure you can switch exhaust housings so you can spool it quicker.

For most part those are big turbos and spool isn't too good on those. Get something smaller or if you want big there are turbos with quicker spool.
