om602 power potential - jltcasper3 - 03-31-2013
Ok i have a spare wrecked 90 300d with an om602 and trans in it. I am planning a antique pickup truck project and am looking for the powertrain for it. What is the potential power I can safely get out of it? I am willing to spend the money on sending injection pump off for 7mm elements and come up with and intercooler for it also. I have read on here people are putting holset chargers on the 603's like the hx35, hy35, hx30?? The 602 is smaller would I be better off with the hx30?? I know it depends on hp level but I want a good reliable driver with not much lag, I don't want it for hot rodding and burning the tires off it. Is 200-250hp to much to ask for?? what about trans upgrades?? any input would help.

Holset hy35 with 7 blade compressor wheel is gold for that engine
9cm exhaust housing

I think you're on the right track in terms of power goals.
RE: om602 power potential - jltcasper3 - 04-01-2013
Does anyone have a holset part number for the 7 blade compressor turbo?? Will it bolt up to exhaust flange without adapters?
RE: om602 power potential - aaa - 04-02-2013
I don't think any of the larger holsets will bolt up to a t25 manifold, they are usually t3.

Where do I get one of these, part number, or stock application?
RE: om602 power potential - HaavardPYA - 04-03-2013
Dodge Ram 5,9 Cummins with 24v up to `02 i believe got that one.
RE: om602 power potential - EDH_Performance - 04-03-2013
But you may rather go for a holset he221w if you are satisfied with max 300hp! These are rather cheap and the best turbo regards spool and performance
It has an t25 flange!
I have one in my 4 pot 1665ccm bmw 8v diesel and with a big 7cm housing i have full pressure at 3000rpm

so the om602 has a t25 flange??

HY35 7 blade 9mm vs. HE221W. Which one spools faster? Is the HE221W the smaller one, limiting HP?
RE: om602 power potential - yankneck696 - 04-04-2013
The HY 35 is used on 01 & 02 Dodge Ram automatics. I'll have one from my 01 for sale soon. Getting an HX 35 for my Cummins. PM me for details.

The he221 has an 60mm compwheel, so it is much faster
have seen 320hp on vw 2.5tdi with this turbo and 6 cm housing

You know that the hy35 and hx35 share the same compressor?
RE: om602 power potential - jltcasper3 - 04-04-2013
so it sounds like the he221w would be a better match for 200-250hp, because of less lag, is that correct.

Is the bottom end forged or cast?
RE: om602 power potential - winmutt - 04-11-2013
HX(Y?)25 is relatively easy to find over at 4btswaps and has a t25 flange. Not sure about 602 but I had a hard time fitting one on a 603 with an adapter.
