the B18a1 thats going into my CRX has over 200,000 miles on it and the high mileage kindof scares me. (the idea of a rod letting go arond 7000 rpms) i'm wanting to use about a 50-70 shot of nitrous. is a something a machine shop can do to the internals, like clean them or something. i've heard some people say they gat there pisonts shotpeened. what's shotpeening do? any other ideas besides a complete rebuild would be nice!

 

bump, come yo
