d15b (sohc) ~130hp
b16a (dohc) ~160hp to 170hp
d15b:
- mas mura, practical at minimal welds lang sa engine bay mo (since halos sakto naman yata ang 1.5 sohc sa city)
- minimal welds > less hassle, galaw > less risk of engine damping failure
- mas magaan, kaya ng stock front suspension mo > plus the city's lightweight > pwede na yan, bilis na yan
- recommended
b16a:
- mas mahal plus more welds to your bay
- more welds > more hassle, galaw > more risk
- mas bigat, di kaya ng stock front suspension, so you most likely have to upgrade them as well
- malakas na makina + your stock brakes + your aggressive driving + the unexpected = lam mo na
(even the SiR's stock all disc brakes maybe underpowered for it's stock b16a engine) - kaw bahala
I run on jdm d15b sa eg civic sedan, and medyo satisfying naman so far.
d15b man yan or b16a, kung hindi maganda ang condition ng nakuha mo, magkakaproblema ka pa rin. mas madali nga lang hanapan ng parts and d15b kasi it shares some internals with out local 16 valve honda sohc engines
