I been using 9s all the way around.. NGK Pt.
I want to try new set up.. 7 for T and 9s ofr L...or maybe even colder ones? 9,10??

iridium plugs make difference? my car has miss firing problem at high rpm.. it is runnig pretty rich..

also NGK plugs are pre gapped??? I jst wanted to make sure.

thanks

 

U cant gap the BUR9EQP and BUR7EQP.
And how did u determine that it is misfiring?

 

Well, the stock plugs are 7's for the Leading, and 9's for the trailing. But the important thing is to find plugs that fit your current mods. What mods do you have now?

I wouldn't bother with iridium plugs. You need to change the things so often in a rotary that those are just way to expensive.

 

full bpu... high rpm break ups at 10psi... car hardly revs up at high rpm.
crane hi6 would help?? i thought about gettting hkstwin... lil expensive..

 

Lets never say BPU on an rx-7 forum again, thats a supra thing.

But anyway, 9's all around should be fine.

 

hehe my bad .. i jst didn't feel like typing dp,mp, ic, etc etc .

thanks!

 

depends what u'ev checked so far to narrow dwn the process. it could be something simple like sparkplug
wires.

 

I changed wires last year..
Im using magencore wires. My ecu is tuned a lil rich to be safe(XS eng)....

really thinking about getting my friend's Crane Hi6..
or should i save money for HKS twinpower?..

 

r u referring to Magnacore? these wires interfer with ECU trips. The EMF is insulation on the wires r not effective. during HIGH RPM it interupts the ECU signals.

 

interfere

 

REally?? Thats a news to me... what kind of wires do you use?

 

stock NGK and Racingbeat wires r good.

 

I always heard mag makes best sparkplug wires.
Neone else knows about this???

 

I'm using JACOBS ignition wires

 

a lot of people dont know. once the wires r new, the assumption is something else.

 

dam i just bought myself a 10mm set of magnicores.. can anyone else confirm on this? if its true ill pick up some racingbeat wires..

 

R u reffering to MAGNECOR??

I got magnecor

 

yes, r they RED?

 

yes magnicor , thought they were good wires myself , i didnt know anything about high rpm breakup. may have to change mine if its true

 

weve tested these on dyno for smog check, this is what weve found on FC3s and FD3s. it didnt pass.

 

Taylor plugs work fine and have less impedance that most cables. Many Houston owners have been using them for over 5 years with excellant results. Crane Hi-6 and Taylors is a great package with no misfiring.

I also run NGK B9EGV at .020" gap. Requires special socket.

 

I'll change it if someone else agrees on this...
I had same problem when i had stock wires.. of course they were old n ****.. but..

that is a big news to me.. always heard nothing but good things about mag wires.

 

That's a load of crap....

I've been using them for over 2 years without any problems.

I agree with Mahjik. Been on Magnecor wires almost 2 years myself. Someone needs to show some proof before they go spouting off bad info..

 

I've never heard anything bad about Magnecor wires. I don't have them myself, so I don't have any first hand experience, but a few friends of mine have had them for 1-2 years and had no issues.
