wow; sucks for those guys. didn't think porsche left any with the slipped sleeve issue hanging in the wind unless there was more to the story.

at any rate, this is the article i was thinking of. it doesn't mention porsche having fixed all of the slipped sleeve issues. must be another article i'm thinking of; i'll keep looking. this one shows all of the failure modes common to the M96 and discusses metal matrix composites in detail.

FYI, the company called autofarm out of the UK who is sleeving these blocks w/ nikasil is not the only company doing this now. i'm pretty sure that phillip raby from autofarm and jake raby from flat6 innovations are related. at any rate, jake has the capability to bore and sleeve our motors for reliability and power. this is great news, becuase THEY HAVE STOPPED making 2.5L replacement motors at porsche. there are like six left; that's it. still expensive to get the rebuild done, but probably about the same as a replacement from porsche. plus, more power & way more reliability. they can get 260HP from the 2.5L.

anyway, here's the article:

UPDATE: the article is 48 pages long and 2.7MB PDF file. it won't let me post it here. anyone have a place i can upload it to & link it here? thanks.
