I haven't found much info relating to Hondas I have 680cc precision a in a turbo civic I noticed one I can really feel the pulse and hear it the rest not much if any noise or vibration... Sign of a bad one? I recently fried a ring land and it could be from it any suggestions how to check ?

Are dsm 750s too big if I grab a set I'm tuning in chrome gold tmrw and just noticed this. The car runs ok holds steady fuel pressure and af the tune is for the old b16 and pretty close

How concerned should I be?

 

No such thing as dsm 750s. No dsm came with an injector that big

 

I was looking into that... They gotta be injextor clinic

 

Could be the injector, but I doubt it.

If you fried a ring land then you need to tear it down. Do it right the first time.

The noise could also be valve last or something else broken in the head.

 

There's nothing broken the swap is rebuilt ground up to ensure all is good.

The injector I feel the pulse much more than the other and am getting them flow tested. Horrible timing tho

 

Swap the injector to another cylinder. See if the symptoms follow.

 

I bet it would have... It's not super major like the injector was working... And wiggling the other I could feel the pulse. Given they are 680 they aren't quiet but still.

I will post the results and probably continue to clean my injectors annually. Hope all goes well I can't risk any fault up top or it will lean out and do the same thing as my last swap

I still think 350-400bhp is too much for a b16 my shop disagrees. Thinking ill hit 285whp for the time being closer to 325-350bhp

 

Injectors cleaned and pushed an average of 655cc across. Seems this method has been used to test and clean injectors for ages. Good stuff...
