My shop just replaced an engine in an sti for a customer. My tech advises every one to adhere to breakin recommendations. This particular customer didn't. Ended up doing the rebuild a second time. The engine lasted 200 miles. Didn't even get a chance to switch out the break in oil. This is an extreme case, but I'm not going to take the chance. My old man bought a 2001 S430 back in the day from the dealer. In 2008 passed it on to my little brother. Car has +200k miles. Original everything. Followed break in. The race engines that someone mentioned earlier have up graded and forged internals that can take the heat. On a stock engine i wouldn't recommend anyone take the chance... Even if this is a super car ; ) after all, those German folks aren't that dumb. Lol
