A know-it-all friend and MB/BMW buff keeps pooh-poohing the SLC 43 engine. He keeps saying it's the "same engine" as some other biturbo used in an older model SUV that did not have much more power than the regular engine, approx. 330 HP, yet cost about $10,000 more. That engine existed, I remember it. I've told him the SLC 43 has 362 HP to no avail for two months now, still brings that up. SO - is there an engine number for what he's thinking of and an SLC 43 engine number? They may be similar, but probably do have different official numbers or other designation I can use to stop him from saying that. Not a biggie but will save some aggravation. Thanks!
