Is there a difference between B16 and B18 LMA's? I'm just asking becaus Honda sells them cheaper than Acura by a buck and some change. I should just be able to buy them from Honda and they're universal to all B series VTEC cylinder heads, right?

 

i know every place iv shoped around for em they do have a diffrent selection when buying them.( make you choose B16, B18 etc). so i think they may be diffrent but im not positive.

 

Are they the same part number? I also remember seeing a thread about H22 LMA's fitting B16's if they are reversed or something like that. And they're alot cheaper. Try searching for that

This thread makes it seem like all B vtec heads use the same LMAs.

However, no personal experience here.

 

Thanks guys, I can't compare PN's because they differ between Honda and Acura, I guess best thing to do is buy a b16 head and compare with my gsr ones. But I'll do some research and see what I come up with.

 

sorry for bumping an old thread
I found on Unlimited Honda / Acura

99 Si use 14820-P30-010 22.25 ea
ITR use 14820-P73-J01 33.79 ea

Different Part number..??

 

yes older ones are smaller and break easier.
