OM617A, hx30 vs hx35?
OM617A, hx30 vs hx35?
Hi, I have a 83 300D with an OM617A (.952), and am looking to do a dieselmeken element upgrade on my MW pump, and get a different turbo than the stock .45 trim Garrett T3. The three turbos I am looking at are a HX30, HX35, or HY35. The HY35 is on the end of my list, and I don't intend to get one unless it is very cheap. From what I've read, the HX30 is kinda big and a good choice. I'm having a little bit of trouble tracking one down on the cheap, but I have found several HX35s. Is a HX35 too big? The particular one I am looking at now is assy# 3590104.

12-13-2020, 10:06 AM #2I have a brand new Holset HX35W-10cm I bought from one of the trusted vendors, Alcaid on here. Will sell it to you at a bargain. The small turbine side should spool up nicely for you. I went another route. PM me with your cell or email and I'll send you photos. Too bad you have a 617 or I could sell you a nice turbo adapter for the Holset but it's for a 606.962. They're probably different although I don't know for certain.
If you're making a 400hp drift car that lives at 4000rpm and smoke is a good thing, then the HX35 is your turbo.
If you want holset, then why not HE221W?
The HX35 is ~40% larger than the HX30, so this should be a simple question for you to answer. The HX35 is a decent choice for a cheap turbo to make 400+hp. The HX30 is a decent choice for ~300hp. I am under the impression that a 617 with 7.5mm elements tuned for good drivability does not make 300hp. So both turbos seem a bit too big for 617.

I see a lot of people using the HX30, and some using the HX35. A HX35 popped up very cheaply in my area, hence the consideration. With the HE221W, it appears something is funny with the wastegate, judging solely from this link: https://www.benzforce.com/collections/ho...set-turbos. What considerations other than the T25 flange are there with the HE221W?

There are several versions of of the HX30 and HE221W turbos, so there is some overlap. The T25 flange on the HE221 isn't ideal, but there are adapters for that. If making the turbo fit is a large issue for you, then the performance difference between the HX30 and HE221W is probably not as important as picking the option that will fit easily.
The HX35 very common due to it's use on the 5.9 cummins. Its cheap and reliable, but absolutely silly to put on a 3L diesel that makes less than 300hp. It throws away all low end power for top end power that could be had with a much smaller turbo.

12-14-2020, 09:20 PM #7I have the new HX-35 10cm turbo and neat swivel adapter for an OM606 if anyone on here is interested. ASSY # is 4051229.
I think the 5.5cm has a T3 housing option which simplifies the install. The 7cm housing might have lower EGTs, but it will also spool/respond slower. Between those 2 housings I would probably start with the 5.5cm see how the EGTs were. They might be tolerable. A good intercooler is going to be key with whatever turbo you use if you really want to take advantage of the bigger pump elements.
