You didn't even read his thread. He's talking about his engine, not the body work.


And, to answer his question, yes some people have shaved the head and bored the block, but with how much some of the work costs, the results aren't pleasing.

 

I had mine bored .020 over (standard rebuild).... gained a whopping 1.3 cubic inches. I dont anticipate any major gains from it. These things arent like boring V8s out (example... boring a 350 to a 383), there just isnt enough displacement to begin with. Because the motor is an open deck sleeved block, you cant bore a lot out of it, because you'll run the walls too thin. You get 2 shots at it. .020 (1/2 MM) over and .040 (1MM) over. After that, you need to put new sleeves in it and go back down to 75MM. I dont know of anyone who makes a sleeve for this motor that converts it to semi-closed deck. The darton sleeves are dry, they just replace the iron liners that are already in there with allegedly stronger ones.
As far as shaving the head... be careful, there's a very finite limit to how much can come off before you compromise the head, and also before you start smashing the head with a high compression (usually dome top) piston. You dont shave the head for a boosted application.

Why didn't you ask in the DC5 forum, if you're getting an RSX? The D17 is nothing like the K-series.
