no clue why it was discontinued but it seems odd to me that its OBD 1 or 2..

isn't the B18C3 the UKDM engine or something?

i just did some research regarding this topic myself and there's no realiable source of info....some site says that it have more power than the 97-01 spec R but on hondaswap i saw this --> http://www.hondaswap.com/forums/inde...howtopic=29825

it says that b18c3 is equivalent that of a GSR....so i'm confused on this myself...i also realized that there's also b18c6 and 18c7....goddamn engine codes

just worry about the c and c5, i have done these engins for 12 or so years and have never even seen anything other than the c and c5. generaly the differences are in compression (piston domes and chamber volume) and cams.

As far as I know, the C3 was the Japanese motor from 96-97 in the ITR. It was refined into what is now known as the B18C5 or
B18C, whatever your flavour.

that would be the c4 i believe.

B18C5er

Yep. Also the Australian market had the B18C4.

imported_Spiderman

ahhh.
Thats what it was.

All these numbers confuse me.

Honda has developed a pretty straightforward means of coding its various engines. Each motor code starts with a letter, to denote the engine family. The two numbers that follow represent the engine's metric displacement. The last two digits, typically a letter and a number, represent a version or revision to the engine.
