I am currently running a B16A in my car but I am going to swap out the block for a B20B that I just put in the macine shop to get bored, re-honed cylinders, port and polish, micropolished b20b crank, type r oil pump and type r water pump. I am expecting a gasket kit in the mail tomorrow to re do all the gaskets. The only thing I am wondering about is a good rod/piston combo with this build. I am looking to run somewhere between 11.0:1 - 12.0:1 compression ratio and I want something aftermarket (not oem honda). what do you guys suggest? I am planning on a thin head gasket, itr exhaust cam, ctr intake cam, adjustable cam gears, skunk2 valves and retainers, type r intake manifold, passwordjdm cf whale *****, jdm itr vtec solenoid, PR3-2 head. thanks for the help

 

I know you said you wanted aftermarket piston rod combo but you should think about the RS machine ITR pistons they make them in 84, 84.5, 85mm and are at a decent price. Cant use aftermarket rods on them but the B20 rods will be fine with your setup just throw some ARP rod bolts in.

 

Yeah I second that, I think RSmachine pistons will do you good and invest the extra money you save into a quality header

 

I can't find anywhere to buy the RS ITR for B20, i found a link to it here on honda tech but the links didnt work for the B20 pistons. I was looking for the 85 MM ITR RS machine just to check them out. any links?

 

try searching ebay or call race axis and see if they still stock them for the B20 thats where I picked up mine.

 

i sure hope your not planning on going with 85 mm pistons on stock sleeves...

 

You can use aftermarket rods with RS pistons.

 

With no mods?

 

Port and polished B20V block
