Hey guys, as you probably know by now, my teg is not exactly the youngest car here...it has 156,000 miles, all highway (the previous owner used to drive from cali to chicago twice a month), but it still runs very tight, and acceleration is nothing less than violent.
Anyway, I am going to turbo charge before the end of the summer, and I wanted to get your guys thoughts on charging an engine with that many miles.....I do not plan on running too much boost though.....What parts should I check/change before I do it ? How many pounds of boost do you think it is safe to run on it ? Do you think with that many miles I should just stick with a T25, or can I go bigger ? Should I just swap the engine out, or can I do it with this engine ?

 

Perform a routine tuneup and a leak down/compression test to see the status of the motor. I'm a firm believer int he reliability factor.

With 156k on the block.. What have you got to lose.

Your clutch on the other hand. That, I would worry about.

If tuned right on a solid motor, 6 psi should be fine. Just make sure you have sufficient spark and fuel press.

 

If you blow the motor its just an excuse to rebuild and then boost more:thumbup:

 

:werd: Bigger and better rebuild is my motto :thumbup:

But mileage is not a determining factor in the running condition of the engine. Like stated above, get a compression/leakdown test. If that checks out ok, you're good to go.
