I'm gonna buy a new engine for my honda city. meron nagbebenta sa akin ng d15. based on my latest research, marami palang variant ang d15:

D15B 130 hp SOHC VTEC-D15B (eto sana gusto ko)
D15B 105 hp SOHC non-VTEC (eto ata yung stock ng city 1.5 ko)
D15Z 115 hp SOHC VTEC-E (ok din sana to. totoo ba 20+ km/l ito? eto ba yung stock ng city type z na 1.5?)

How do i know just by looking at the engine kung anong variant ng D15 yung tinitignan ko. thanks!

any other suggestions on where I can buy the 130hp d15b?
