Now that my shake rattle and roll issues are behind me, its time to turn the wick up on the Meth injection. are the plugs the same? is the gap the same? I also have the HKS twin power module, if that matters. If this is a re-hash, I apologize, tell me where to look, or just fill me in on what plugs I should use, and what gap. Thanks in advance!

 

i run a reflash with the dli2 and my car runs the best on NGKBPR8ES with a .28 gap. the larger gap is fine because of the ignition amplifier

 

Yep same plugs. I personally use NGK BPR8ES.

 

o yea thats at 30 psi on pump gas with 100% methanol

 

Thanks guys, I appreciate it!

 

One step colder than stock...anywhere from .024-.028" gap works depending on boost. Closer gap for higher boost since misfiring usually occurs on stock ignition and high boost.

 

thanks nito99, I have heard the coils blow on the 03's, I have noticed a HUGE improvement with the HKS twin power, smoother idle, and stronger rpm powerband, with the increased spark signal. Has anyone used the coil on ignitions? ie Bushurs? I think i will get one of those, and see how they work also. Any input on those?

 

C.O.P's aren't necc. unless you're pushing over 450-500hp.

 

did not know that, thanks for saving me the extra dough on that one! I am getting close, but not there yet.

 

Those guys above know more than me but I would use BR8ES gapped to
0.025 - 0.027" stock ignition/elect <22 psi
0.022 - 0.025" stock ignition/elect >22 psi

 

Watch the decmal point everyone: .28 would be 1/4 inch gap. You must of meant .028 or, properly put as 0.028.

 

I had them at 1/4 inch, the damn tip was strait down!!!!!jk, I will gap them right. Thanks again.

 

The coil on plug doesnt really do you anything. They come from a Chrysler Sebring if you wanted to know. The reason they are better is IF you run an ignition amp. By themselves they wont help too much.

 

yea i meant .028, sorry for the typo

 

I have the HKS twin power ignition amplifier, does that qualify? do I need one then?
