No offense, but it just sounds like a bad idea. If you're going to have to rebuild it anyway, why not spend the money and do it right the first time? The way you're looking at going (I seriously don't understand the advice you've been given), you basically drive it till it dies then do the work--when the engine could be in even worse shape and need more things replaced/rebuilt. I don't get it...then again, my mechanical advice right now isn't worth the electrons inconvenienced in its delivery :-p -Bryan

To: "miatapower List" <[email protected]> Date: Tuesday, June 10, 2008, 2:21 AM I've posted on and off about my engine "troubles" so I apologize if any of this is repeated. I have a 99 10AE that just tipped 70k miles. I'm planning to add a turbo (specific kit / parts not yet determined) with a Megasquirt ECU for engine management. I plan to start at around 5-6psi and upgrade from there. First step is to get the MS wired up and working, then I'd like to add the turbo. However, before starting anything, I checked the compression on the motor and did a leakdown test that showed leaking around the rings. Dry/hot Compression: 175 - 152 - 150 - 175 Wet/hot compression: 200 - 187 - 180 - 205 Leakdown: 25% - 35% - 35% - 10%I am not using any appreciable amount of oil now, and the car seems healthy (aside from the numbers). I was shopping for a replacement block, or a reputable shop to rebuild the bottom-end, but it's been suggested that I should just turbo the motor that I've got, and deal with the engine rebuild in the future. Considering my low (initial) power goals, how much of a gamble is this? If I could squeak out 6-12 months on this motor before it started using lots of oil, I'd be a happy camper. What do you guys think? Any experiences boosting a motor with numbers like mine? _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
