I run a small business doing performance builds on high end vehicles, Raptors being one of them... During research on buying built performance ecoboost engines, I found RMB to be well recommended and received... I ordered a Gen1 as well as a Gen2 ecoboost 3.5 for a few builds.
HOWEVER, after spending tens of thousands of dollars on builds, (a gen 1 ecoboost, a gen 2 ecoboost, and a handful of Mclaren engines,) I've had some issues.

- The gen1 ecoboost started knocking within 20 miles, Ryan actually came out and tore it down in person... fantastic! Couldn't find a problem, it came back intact and runs fine (albeit late)
- The gen2 ecoboost blew up in under 3000 miles, catastrophic failure. Loss of compression on left bank. Timing guide exploded, apparently due to a tensioner failure.. At this point RMB stopped returning calls...
- The Mclaren engine suffered an unknown failure, we're going to have to eat that one too ($$$$$) again no response from RMB
In between ordering the gen1 engine and getting it running, I was impressed by his knowledge and apparent integrity, and employed him to r&d, develop a rotating assembly, and put together THREE mclaren engines, with about half a dozen to follow after the first were received. I sent over $150k in engines to his "shop," with promises that the first engine would be delivered in a few months. Six months later, there were apparent problems sourcing bearings; no problem, I discussed the issue with my clients and we agreed to go with a billet crankshaft. RMB was to spec a custom billet crank, and order ten units to start ($30k for the first 5, the second 5 would be held as shelf stock by MFG)
Turns out I was bull****ted the whole time, the cranks were never spec'd, as RMB decided that he'd spec and throw together his own stroker setup for the ecoboost platform instead of ours. I finally got fed up with getting bull****ted, and drove all the way to NJ (over 12 hours) to retreive my parts. Turns out, none of the engines were even in the shop... they were in a storage unit, and I had to jump through hoops and wait nearly 24 hours to even get my ****. One engine block and two sets of liners was missing, the custom pistons and rods we bought were scrubbed of part numbers and reboxed, and no machine work whatsoever was performed. the torque plates we paid to have made for the blocks were now his property apparently; and after begging to "borrow" them so another machine shop could hone our blocks, one lie after another about shipping and tracking. We are now being sued for nearly half a million dollars due to RMB's lies and deception, and failing to meet delivery dates due to broken promises.
Curious to know if anyone else has had a similar experience?
