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?
