Soulfly is your car a white EF similar in your avatar? I think I passed by a very clean white EF on LDP. If you noticed a red karer eg dirty like hell.. that was me..
Anyway.. just to answer some of your questions... and increase my postings hahaha.. :P
OOps.. first to correct you... Big B16a and small B16a refers to the 170ps and 160ps engines. both are DOHC Vtec. The SOHC is not a B16. Try not to refer to big B16a and small b16a.. these are only words used by locals aka pasar talk.. similar like dolphin, belalang, katak, beruang, etc... all just pasar talk.
THe proper one is B16a first gen and B16a 2nd gen. Then you have the B16B. B18A, B18B, B18C, B18CR, B20
B16a 160ps
cable clutch
cover difference , PGFI I think is a different colour
B16A 170ps
Hydraulic clutch (however the first generations I believe might have cable clutch)
PGFI difference.
Sepat.. I don't think the DOHC vtec stickers prove anything hahahaha.. everyone seems to have a NISMO, MIVEC, VTEC, TYPE R, TRD, bla bla bla bla.. JUN etc etc.. sticker on their car.. hahaah..
