Either by voluntary upgrade choice or due to implosion, if you paid out of pocket to replace your engine or rebuild it, please let us know what was performed (straight swap, rebuild with upgrades, etc.).
And most importantly the price you were quoted (you can keep the price you actually paid to yourself if you wish). You also do not have to disclose which shop did the work if they don't care to see their shop's pricing showing up in a forum thread.
Over the years we've seen a lot of numbers thrown about when discussing this topic but I'd be curious to hear about real world experiences.
