imo the b18c series block is the key to FI
its one of hondas best and strongest blocks

the frm in the h22a makes it begin burning oil quickly when boosted. sleeving is necessary for any serious boosting and general longevity

the h22a makes a decent amount of torque over the b18c series

but again one is a 2.2 liter and one is a 1.8 liter, 2 different engine classes

either way you will be building up the bottom end for FI on both the engines
connecting rods

i also think using a headgasket to lower compression is one of the worst ways to do, less compression means less power also.

dont be so quick to lower compression

rather than building a block to withstand detonation and lowering compression, try tuning

and that where an intercooler comes in, as well as proper fuel mgt.

and as i always say

its all about tuning
DIAL OUT THAT CAM DURATION
