What Engine Shop Should I go with in Colorado - Spun Rod S54

[Briggs]

Hi Everyone,

Hi, I'm Aaron - I am in the Nasa RM region. I have been tracking my BMW E46 M3 for about 10 years of and on. The car has about 145K miles on her - Bearing replaced at about 55K

Unfortunately, I am pretty sure I have spun a Rod Bearing at my last outing at HPR.  Although, there is no metal in my oil, or oil filter, so I am hopeful the damage is minimal. For now, I have no rods shooting out of the side of the block. But it makes a heck of a ticking sound with any revs

For my CO BMW folks- 

What race/engine shop would you recommend for doing an engine swap. If I go that route. Or is there a shop that can just rebuild the bottom end? Other than the bearing the motor has been strong. So I am open to the option of a rebuild if possible. However, from my understanding it sounds best to just swap in a new built motor ?

I have worked with SCR performance in the past and they do great work. I am sure they could do the job or work with en engine builder. However, I am located in CO Springs, so I am wondering if there is any place closer to me that can be trusted to do the job?  

I have  also considered a Lang Racing stage one engine, or Rouge Engineering offers something very similar.  I am looking for a shop I can trust that understands what these engines go through and that can make the swap if I have one of these motors shipped in. 

 

Does anyone have experience with this issue?

 

 

 

 

Thank you,

Aaron

Hey Aaron, that sucks about the M3, I feel your pain. If you're in the Colorado Springs area, I'd check out RM Motorsports or Lutz Performance—they’re both solid when it comes to BMWs and could handle a rebuild or engine swap no problem. I’ve heard good things about both from other BMW owners around here, and they know their way around these cars. If you're not set on swapping and think the bottom end might still be okay, it’s worth getting a second opinion, but if you're leaning toward a full rebuild or swap, those shops should have you covered.
