Workin at autozone we have a few people workin there who really know their stuff and i was talkin to one of them the other day about boosting my z6 with 161k on it. I was sayin a rebuild would be inorder before puttin that kind of stress on the motor but he claimed that its better to put forced indiction on a high mile motor cause they have more "give". While a fresh motor would be rigid and tight with no give. I'm guessing that his def of give is just room for error to some extent. thing is he is goin on V8 and diesel performance knowledge. Him and his dad own a turbo diesel performance shop down in south florida where they make dragsters and quick diesel trucks. Lets assume that for large displacement diesel motors and other V8's its better to have a high mile motor. Would the same go for littke honda motors? Or does someone want to shoot this whole thing down? Let me know what u think.
