Is it worth advancing the timing through the distributor on a b16a? Will there be any noticable gains? TIA

 

Yup.

 

I advanced mine 4 degrees.. noticed a big difference in midrange power.... pulls much harder!!!

Run it on higher octane fuel tho to avoid detonation but keep ure ears open for it pinking! I run mine on 98octane in the UK and it seems good

 

I've advanced it on a dyno on a b16 and seen gains of any where from 0 to 6 hp. It will just depend on what mods you have done to the engine, but generally 2-4 degrees of advance will produce power at most rpms. However, more is not usually better. I've never seen 6 degrees of advance produce any more power than 4 degrees. Also, if you are using a chipped ecu already I wouldn't advance it at all.

 

what about advancing with a zydene ecu? I remember right after I did my last swap it was at 23 degrees on the way to chicago (250 miles) pulled hard but it was considerably hotter as far as the exhaust goes, its now back to 17 and doesnt seem bad.

 

Advancing timing = You will loose on the top end, but gain on mid and low end.
Retard timing = Loose on low and mid, but gain up high.

 

i have my nearly stock b16 set @ 17 degrees i think stock is 14 or 15 plus or minus two....w/93 octane doin fine.

In theory this is correct, but in pratice on honda motors it most often is not.

 

I gained quite a bit in the 1/4 from advancing 2 degrees - about 0.2s.

I gained quite a bit (of ping) from advancing 4 degrees.

This was on 94 octane, BTW.
