om602 power potential
om602 power potential

03-31-2013, 06:58 PM #1Ok 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.

(04-02-2013, 09:36 AM)aaa I don't think any of the larger holsets will bolt up to a t25 manifold, they are usually t3.But it is easy to weld a t3 flange to yout om602 turbo manifold

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

(04-04-2013, 12:09 AM)TurboWalt HY35 7 blade 9mm vs. HE221W. Which one spools faster? Is the HE221W the smaller one, limiting HP?
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?

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.
