Hi m, friends i need some help with my engine, i have a F20B DOHC Vtec in my SiR Accord and i already bought a turbo kit for my car, but i need to know which forged rods and pistons fits in my engine, i don't know which i have to install

 

there is nothing off the shelf for that engine, everything will have to be custom made.

easiest thing is to use h22a4 crank, h22 rods and custom pistons.

 

i thought the f20b comes stock with forged rods and crank?? with a good tune you should be able to make decent power with out upgrading the internals right??? should make decent power on low boost since compression is so high right? someone correct me if im wrong

f20b comes with the same mess thats in everyother honda is made of, no forged anything

 

they are pretty strong from the factory but running 11:1 wont be great for to long .

search for user name " THIS ONE"

he used a forged high comp f22 piston , but due to wrist pin location it was estimated around 9.5:1

 

"this one" is matt from one ***..

his "F20b" had all h22 parts inside

if you use f22 pistons in an f20b they will stick out of the block a good bit
