My question is, around how many miles is it too late to begin any major engine work. ie. Supercharger, turbo, cam, nitrous, and so on. i mean, i would want to save up for a supercharger, but could my 100k miles car take it?

 

im not sure but i have 102 on my care and i had a guy tell me that i really depends on how the car was treated and that i will be fine at 102k. Off topic how do u like ur u/d pullys? can u feel a diff?

 

Do a compression test. That will tell you.

 

yea i felt a little difference when i got the pully's put on, not a HUGE dif, but some.

 

+1 on the compression test.

 

What kind of compression are these motors suppose to have anyways?

 

how do i go about getting one, just go to a shop and request one?

 

man, if you are planning on f/i, a ruilt engine is a good idea anyway. then, with a new bottom end, you dont have to worry so much about the "age" or milegae of your engine. you got fresh parts, youll be good to go. just dont forget to streghten your drivetrain with it, or that will be the next weak link.
