I have a 96 b18c ITR, wiseco 9:1 pistons, eagle rods, pt5831 turbo, e85, id1000 injectors, hondata s300, bkr7e plugs gapped to .018, 11psi roughly boost

I just got everything together and i was noticing when i originally gapped plugs at .028 i couldnt go above 5k rpms before breaking up. I lowered gap to .020 and now i can rev to 6.5k before breaking up. I tried .018 but it feels the same.

Cap, rotor are new OEM honda, wires are NGK blue a few months old, not sure if something else is wrong causing me to need to decrease the gap even more. Let me know if you have any advice.

 

It shouldn't be gapped that tight for only 11psi. Do you have an OE distributor or an aftermarket replacement ?

 

sounds like your coil is dying. Buy a new oem coil

 

Its an OEM distributor, it has a newer OEM coil from about a year ago.

 

I am thinking of just going hondata cpr... and being done with it..

 

I just lowered my gap down to .018 this week after blowing the spark out at almost 30psi, I had been gapped at .023 before that and was at .028 up to 15 psi. Blow out is not your issue, you sure your not leanning out?

 

AFRs are mid 11s in boost.

 

Checked bat voltage and is normally about 14v, at WOT dips to 13.5v, i assume thats fine.

 

There should be voltage offsets in the programming, but in that voltage range there shouldn’t be too much fluctuations I wouldn’t think

 

Also might want to swap out the igniter in the distributor

 

OEM or Genuine Honda coil? OEM is not the same as factory part.

 

There's nothing wrong with supplementing mJ of energy by using an MSD or Mallory ignition system, without going to Coil-On-Plug. (And a Hondata one at that....)

 

Its a geniune honda coil as far as i know, from JDM motor.

I have bee researching and thinking about going m&w pro 10 with t1 harness. All these distributor parts are so old, and new OEM parts are very expensive if you can find them.

 

Again, you don't need to go as far as M&W Pro1. you can keep it simple.

 

did u try another spark plugs?? iridium are best

 

TheShodan,
Do you mean just getting a cheaper ignition then the pro10?

1HGEJ2,
I tried BKR8EIX at .025", same thing happends

 

Yes. Keep it simple with Mallory or MSD system with an external coil

Changing to a heat range of 8 will cause idle issues, even if you weren't still blowing out spark. changing heat ranges doesn't change the amount if mJ of spark.

 

What is a reliable external coil you would recommend?

 

MSD Blaster SS.
