Anyone built up a D15/D16 like pistons, port and polish?

I was planning on replacing my D15B2 with the JDM D15B. Then I talked to a guy that knows a lot about cars etc, he said that I could take the motor I have, he could port and polish it, get better pistons, bigger fuel injectors, and make more horsepower than swapping the engine, and also have stronger internals.

Has anyone ever built up a D15/D16? Is it really worth it?

bigger injectors arnt going to give you more power, they will make you run really rich and waiste gas. ported and polished d16 with high compresion pistons would probly make 15 more hp.

You say "probably" is there anyway I can find out for sure? Plus, I have the D15B2, what are the differences in the JDM D15B other than VTEC that makes it have 130hp compared to my 92?

Well not all porting and polishing is not allways the same so it varys alot. As for differnces, *usually* jdm has differnt cam(s) pistions, and maby a few other things. maby someone else will answer with the specifics.

Yea 'cause I was trying to tell them that the D15B2 is the same size as the one I want to swap, and they were like well how does that motor put out almost 40 more hp? More valves? Bigger valves? Different cam? And how does VTEC actually create the horsepower? These were things I couldn't tell him.
