OM603 ideas for 300-350hp
OM603 ideas for 300-350hp
So i have been digging around in the threads here and learned about the 603.
-Heads that Crack have the casting number 14,15
- NA splits rods around 400hp depending on turbo size
- 606 rods have been used in 603 because there stronger
-6mm elements can be swapped from 606 to 603 but need calibrated for smooth operation.
-hy35 for mild performance
-hx35 not quite wild
-he351 is VNT or WG. rod bender for NA 603
I had the w123 om617 then sold it, had withdrawls from it and was on a rant for 606 but there to rare and expensive so im looking into a Turbo 603 w124. at some point i want 350hp. I will get an EGT and Boost guage to see how a stock one is tuned and when modified say away from 1200*f
1. what can the stock pump support with a hx35?
2.manual gear box option and clutch?
I've got a stock number 14 that has to be pushing 300 or near it. The engines can handle it (or making them so is relatively easy), everything else behind them has to be replaced and is more difficult (imo) to source/plan/execute.

I've got to admit, i'm quite surprised about the 603 NA. I've had it up to max rack travel with stock (bosch, no dieselmeken or something) 7mm elements and hx35w with my redneck trottle (trottle hooked up to the rack ) And held up surprisingly well... I still want a dyno run at my job but the clutch is bad. I'm guessing its about 300-350 hp daily driver. Goes easily over 220 km/h (max speed on tacho)
For a trans, get an adapter plate & put an AX15 from a Jeep or Dodge product. That should hold well.

I don't know the story, I bought it as a spare. But it certainly didn't come off a highly tuned engine Probably just abused like so many...
The cylinder head casting... higher number the better
Check the coolant res and if it's nasty looking (purple/brown/black ish) the car probably overheated at some point and may or may not have been fixed. There's a detailed w124 buying guide out there but I forget where I saw it. Google w124 buyers guide and you'll probably find it, I think it's from another forum member over at peachparts ? Been awhile since i've referenced it.

emailed the folks there and bob here replied quite promptly if i might add
"The kit, once installed, enables you to use all Chev flywheel and clutch parts from 1985 and older 350 engines. Using a T56 however is a bag of worms. The only T56 that will bolt right up to my kit without
modifying it is the one that came from behind LT1 engines.
Bob"
so the th350 and all the other transmissions are up for grabs. l believe i will go this route.
@jeemu
where can i buy 606 rods at? I think this 603 needs 450hp to the wheels
If you use a TH350 and a loose converter, the stock gearing might work out.
well there is the 700r4 which is a overdrive trans too. then for the techy people the 4l60e and 4l80e. and get a tranmission standalone controller. which could be a flappy paddle gearbox if one was inclinded to have a car like that.
