I'm not sure which plugs were installed in my car but I did end up burning a small hole in the mother board of my P72 ecu, is it possible the electrical surge that is sent back from a non resistor plug could cause that? I read earlier in the thread that non-resistors can cause idling problems which is something I'm experiencing now.

I don't have a picture of it but I checked my plugs (same ever since I swapped the engine) and they are a resistor type.

So i purchased these for my turbo b series build. Not chasing big power like 300-325 or so. Would these plugs be too cold, or they are ok?

You should discuss the plugs used with your engine builder or tuner or both.

I'm a big fan of using BKR7E's in turbocharged Hondas making power in the range you're looking for. I think you're on the right path.

Yep with all the research i did, it seems these plugs are the plugs to go to . I'm wondering what gap will be fine. I wrote down all the gaps and i believe they are at .031 thousandths and i think I'm going to start at .025 clearance and see how it's looking.

That's a decent starting point. I have mine at 0.020".

If you start breaking up as boost comes up, you can try tightening your gap, as it may be blowing out the spark.
