> Sound about right? If you’re sleeving the b16, what mm are you boring out to? I ordered 84mm for 2.0L on GSR crank. If you go stock dimensions for B16 you’d need more boost to make 500 whp…and a GT3582R will do it on the 81mm from my sources.

My Opinions…  
-Wiseco pistons come with rings (id just use them)  
-Hondata intake manifold gasket is junk. mine melted/deformed  
-38mm is way to small for 500+ i boost creep like a mofo. wish i went 44mm  
-Hondata S300 FTW, i dont like crome on big $$ setups (thats just me)  
-dunno if id run a walboro 255 pump for 500+ they make a setup for (2) 255’s intake. id run that or a sump  
-Also when it comes to mani selection…LifteTime Warranty Pays Off!
