Decking/Machining question
I'm currently building my motor to be boost worthy. I'm close to sending it off to a machine shop for some work, but I am still unsure of one thing. That is if I want it decked or not, and if so how much?
I was using this site http://www.c-speedracing.com/h...c.php To determine my CR and imput as follows: B18A1 Block - 81mm x 89mm B18A1/B1 Head - 45cc/Cylinder Piston - Other - (-12) Dome Displacement - Wiseco model no. K541M81 Gasket - Other - .025 inches - Cometic HG Piston To Deck - OEM B18 - .030 All calculates out to a whopping... 8.143703808595147! That is crazy low. Though I'm not sure how accurate that site is, I would like to know what my options are in this situation. I want at least 8.5 CR. Unfortunatelly right now I cannot afford a Vtec head, and probably wont be able to till next summer, so I need to deal with this issue now. Any body want to shoot me some options that don't include getting rid of my current pistons or my stock stroke Eagle rods?! Thanks much! |
Re: Decking/Machining question
Just have them deck it the least they can to make it flat.

Re: Decking/Machining question
Decking is when you make it flat. Milling is when you're taking material off. Same process, yes, both take material off, but decking means just make the ---- flat and dont take anything off.
Unless you're dead set on milling, I'd have them check both surfaces and if its fine it's fine. |
Re: Decking/Machining question
if you want higher compression then go for it, but i'd personaly keep it where it is for a turbo setup
