Hello , Getting right to the point. at the moment I'm installing a Greddy Turbo kit Bolt on in my Rx8 06 , I was wondering Is it better to have the Iridium Spark Plugs or Copper Spark Plugs.. I test Drive the car today, but it turns off when I'm a stop sign... Help.. please.

 

You have an air-management/installation issue and the factory Iriduims are the best plug to use with the GReddy kit as it comes from GReddy.

 

its probably more to do with the tune/install of the kit then the spark plugs

 

It could be ANY number of issues, the least of which being Ir vs Cu plugs.

Do you have a BOV? Venting to atm? Recirc that byotch.

In all seriousness, you might want to list ALL relevant details, including current modifications. What are you using to tune? What exhaust? What intake? Where did you get the kit? Is it used or new? etc

 

I do not have Many things that I have on the car, I have a Cat delete from Agency Power, Exhaust from Greddy, Spectrum Elite SE exhaust system, Iridium spark Pluggs From Greddy as well, and Agency power Under Drive pulley. Thats about it, and the Turbo kit.. That is the only problem I'm having.. the fact that it dies at the moment I stop at a stop sign... And I bought as well the Blow off valve... And ALL the parts are new...

 

You still haven't informed as to what EMS you are using.

If you are running a maf ems, you will want to recirculate the BOV. I had EXACTLY this issue the very first time I drove my car following install. The recirc fixed it.

Who is tuning your car?

 

have a feeling his using emanage ultimate that came out of the box

 

Yeah I'm Using the E manage Ultimate...

 

have read this thread and applied the fixes to your set up?

are you venting to atmosphere or are recirculating?

edit- are you using the emanage with the tuen that came int he box or are you having it tuned by someone?

 

I'm using the E manage that Came out of the Box.. and yeah I'm Venting to the Atmosphere.

 

I got it Guys.. I realized that It's not pumping enough Fuel in to the car. I need to re-adjust that in the ECU, so that it can send more...

 

If that doesn't work, get a compression check.

 

you need to change to recirculate AND you need tuning

 

fixed

 

Uh, venting to atm generates a rich situation, so adding MORE fuel may not be the answer.

The key here is that the OP needs to take a patient, logical approach to working through these issues. Does he have a wbo2? Is he logging data? How did he make the determination that he was too lean? I worry that this thread is going to lead to a "FS Greddy turbo kit" thread.
