i need to know what spark plugs are good on for this motor and suport these mods as im running it in about a 1bar boost ...

also what plugs are good for the same car with single turbo set up set to 1.5 bar .

thankes ....

 

I have a street port single turbo. I run NGK bur9eqp and bur7eqp. I cant remember which is leading and which is trailing. I also know that some guys run 9's all the way around. If you just purchased your rx7 or you are just starting to work on it. I strongly suggest reading some of the sticky threads and searching before asking questions. Congratulations and good luck.

 

thankes and no i didnt just buy it i have had it for about a year and a half .aslo this is the motor i have been builting for some time now and just wana be save using the rigth spark plugs ......

thankes again ..

 

most people with those types of mods run 9's all around. keep an eye on your injector duty cycles if you aren't already.

on a single turbo running 1.5 bar, you might need something around 10, 10.5 or 11 depending on your ignition components, tune and fuel system setup. do a search in the single turbo section for more info about that.
