S55 Swap OG M2

1slowm2 · 08-26-2022, 12:16 PM

My M2 was running around 650whp on the stock block n55 engine before it blew. Mod list was:
* Big boost kit 3.4 (70mm)
* Spool performance fx-150
* Fuel it port injection (950cc)
* Fuel it stage 5 Ipfp (dual 525 pump)
* BPM4 low pressure fuel pump controller
* Turbosmart bov*

I decided I didn't want another n55 in the car so I found a great priced, low mile s55 engine and swapped it in. Took a lot of coding and tuning but in the end was all worth it.

How's it sounding/running on the S?

How does it handle with no front end bracing?

Awesome. Is it CARB compliant? I read somewhere later motors from the same model car is easier to get approved.

How much did it cost to put this all together if you don't mind sharing

Handles great. I mean it is a m2 🤣

Around $14k for engine/ coding/ tuning/ labor

Was thinking about this if my N55 ever goes bad *knock on wood* that never happens.

Comp with OG front face. It's perfect!

Hello ,
Congrats on the successful swap & the choice of an S55 .At the point of a blown engine the world was your oyster as far as any & all engines .
Were you able to determine why the engine let go & approximate miles driven after the mods were done ?

Thanks
Dan

I believe engine detonated due to super knock at around 170mph causing rod to shoot through bottom of block and sending oil and fire down the whole side of my car. Honestly can't believe the car didn't burn down. About 12k miles on all mods

I mean, this begins as a sad story, but also an unbelievably bad ass story.

Man pushes m2 to insane power levels, finds the limit of the motor in a blaze of actual fire at 170mph and then S55 swaps the remains.

5/5 sir. No notes.

Clean job, looks factory (

Are you running any of the Comp's cooling hardware also?
