Whats up. I am looking to rebuil my d over winter. There is a guy selling a set of crower econo billets and SRP forged pistons (.020 over & 9:1 compression) for $600. I was going to go with the vitara piston combo, but this seems like an awsome deal. My two questions are how much do you think it would cost for a shop to bore .020" and how well will the stock sleeves can handle boost after this much material is take away? Will it effect their stregnth a lot? thanks for any help.

 

.020 over is a very small amount of material taken off. It won't affect the sleeve strength very much. Pricing will vary alot depending on what machine shop you go to. I think I paid about $150 for a hot tank, bore, and hone.
