I need to know, from those that are already, what spark plugs (7, 9, 10, etc.) are you running with your current mods and why? ...for example; are u running your T=7/L-9 or T=9/L=9 and why? My car is a daily driver by the way with the following mods.

red '93 touring performance mods;

apexi fmic
apexi power intakes
cosmo fuel pump
apexi power fc w/ commander
down pipe
straight pipe
n1 dual exhaust

future mods;
koyo radiator
extra oil cooler
1300cc as secondaries
rising rate fuel regulator


see ya,

car 53

 

Running BUR9EQ all around. My mods are in my sig. VERY similar to yours except that I have an ignition system. I run 9's because they're a cooler plug. Also because I can never get my plugs wrong. Also because 9's in the leading last longer than 7's...especially when you're modded like me and you

 

I remember asking you about your injectors. I'm still debating whether to go 850's all around or 1300's as my secondaries. It's more or less the work involved. How easy is it to modify the 850's to the primary injectors? Don't get me wrong, I don't mind doing the labor, I just don't want to be off on the grinding portion.

 

Hey, What's up

All you do is take the primary injector rail completely out. Then you shave the top down approximately 3-4mm down(about 1/8 inch...but if you're not sure, then too much is better than not enough). Use some rough sandpaper. Put the 850cc injectors in. Put the top on them and screw them down and put your injector rail back!

Good Luck!

 

You have to be kidding !! I canīt believe thatīs all to it ... So then, why do people SELL 850īs for use as primaries ..

..or they dont sell ém ?!

 

Because people can't tune...seriously.

My car idles just fine with 850cc injectors in. I'm not running rich. I don't have any stumbling problems...nothing. I set them and drove...
