No one uses Block guards anymore, The only thing the K has over the B is IVTEC and a better cylinder head.

THe K shares alot with the H22 believe it or not.

Bottom line is you just are giving out bad information. The FRM sleeves are FINE. Why do poeple advocate iron sleeves? its because the OEM sleeves whether its FRM OR NOT, fail past 400whp.

if its 400whp an under, stock sleeves, FRM OR NOT, are FINE.

Emminos car makes great power, but he cant rev it high. But he also has a 2.3 liter.

an h22 with the same turbo kit versus Emminos setup, the h22 is better, id rather have DOHC an 1000 more RPMs of powerband, than .1 L.

but what do i know....

Apparently mazda people know more than me when it comes to hondas
