milage is IMO not really a good way to judge what shape the internals are in. If you want to know how good your running go get a leak down test and a compression test. Those will let you know how good everythings lookin and sealing up.
I will have to get those tests done. thanks for the info. I have heard of people running the JRSC between 150,000 and 170,000miles.
What do you think those tests will costs me ( I know, I will call around )?
I plan on rebuilding the motor later on, I just figured I could have a few years (1-3) of fun with the supercharger before I do. Plus, It wouldn't be that big of a deal to rebuild AFTER the supercharger has been on for a while....... or would it???
