om602 in a w114?
I apologize if this has been asked before, but after several weeks of research, engine searches, dead ends, ect. I feel it's time to ask people who know more than I do about the subject matter at hand. I recently traded my daily driver for what by all accounts appeared to be a good condition 1969 220d. Unfortunately the motor didn't make it out of town, much less back home. In light of the stock 220d's lackluster performance, I've been searching for a newer and better MB diesel engine to replace it. The original plan was to replace it with an om617 turbo motor, but locating one with reasonable mileage has been problematic. What I have been able to locate, however, are a '92 om602 and a '96 that could either be an om601 or om602.
From what I've read, either motor would satisfy power requirements. I mostly need help on fitment and wiring questions. To begin with, I've read that the w114 requires tunnel modification to allow an om602 to fit. I'd like to get a better idea of how much it would need, whether anything else needs to be modified along with it, ect. I'd also like any information on om601 fitment as I've not seen much discussion about it being used as a swap candidate.
In addition, I've not seen the exact requirements to run either engine posted anywhere yet. I'm under the impression that it requires an ECU for the injection pump, but not much else in the way of electronics. Any info that someone could provide for me would be greatly appreciated.
If there's a better route out there that I'm not seeing, I would be more that happy to listen to an opinion on it. My only real preferences would be diesel and something with the potential to be reliable after performance modifications. Or if anyone on here has a running om617 turbo motor they'd like to sell within ~2 hours of Morristown, TN shoot me a pm.
A big thanks to anyone that takes the time to read this post, I certainly appreciate it.
