Greddy Turbo Kit -- Sparkplugs ?
I am in the process of setting up a Greddy kit for my car... came across this link for associated parts recommended for the Greddy Turbo kit:
http://www.rotaryinsider.com/faq-tac...cost-gap62.htm
Everything seems pretty straight forward, only question i had about was the spark plug recommendation.
"9. Spark plugs. You'll want to run colder plugs on your turbo. The stock plugs run about $35 each and are too hot for this application. It's recommended that you get the NGK-5255 plugs. You'll need four. Figure $50 for a set. RECOMMENDED"
Havent read about too many on the forum having to change to a cooler running spark plug... So i am hoping someone can shed some light on this ? And would it hurt to run these cooler spark plugs ? (all 4)

Cool, I have a BHR Ignition kit coming as well. I purchased 4 of those spark plugs for pretty deng cheap... but then i started to think that maybe i bought the wrong ones, since the oem ones are soooo much more expensive. Will these work for all 4 spots, trailing and leading ? I know the oem ones are different trailing vs leading.

I've searched man... Read through many people's build threads on the Greddy kit, learned A LOT, and like i said i havent read of many (or any) people switching to these colder plugs. Just asking for a simple answer, that is all-- Am i able to use these same 4 spark plugs in all plug positions without any real adverse effects ? If not please feel free to school me, or link me. Thanks for the help !

You know what 9krpmrx8, I have actually looked through the "Turbo Owners - Please Fill This Out" thread.... skimming through it, I never noticed the column for plug type. So in a way, thank you for answering my question.
Just wondering... wouldnt it have been easier to just fill me in with the answer ? or link me. I also hate when people ask general dumb questions aka "how do i turbo my car ?" I dont post much, and I only post when I am looking for guidance or advice. There's so many people on this forum quick to yell SEARCH NOOb...... when this should be a place to help others as much as possible. But who am i kidding--------> every car forum is like that, ha.

It would have been easier but I'm trying to make a point man. Turbocharging an 8 is a big endeavor and the stickies are there because they contain useful information. If you make a habit of skimming over these threads then you are doing yourself a disservice. Don't be lazy man, it will cost you. Trust me, I speak from experience.

if you track an FI car it would be best not to use the oem plugs. I do know that.
Basic rules for any FI--especially with our compression ratio etc:
1- use the highest octane gas you can resonabily get and tune for it.
2- use the best ignition system you can afford( that includes plugs!)
3- insure youre fuel pressure is adequete at all times
4- get the temps under control
5- FI on this engine means a more intense maintainence scheculed is needed.
So yes a step colder plug is recommended. Just because some use the oem plugs and get away with it doesnt mean thats it is ok to do.
If you run the strapless plug then you really need an upgraded ignition system. Those plugs have a big gap that has to be jumped. If you run a plug with a grounding strap--CAREFULLY reduce the gap to 29-30. denso plugs have a more robust strap than the ngk and it can be adjusted with more confidence. The ngk plug strap is easily broken.
After all the money a person spends on an FI install---dont cheap out when it comes to spark plugs.
Seems that I am the only one running the step colder denso's? I didnt see anyone listing them on the stickie.

Appreciate the feedback fellas ! I'm looking to run the NGK-5255 plugs in all 4 positions along with the BHR ignition. I baby my car, and ill be playing it extremely safe trust me... I'm stationed in Germany and I'm looking forward to running the 'Ring here in spring, WITHOUT the turbo setup. I just dont feel comfortable pushing a turbo Renesis that hard, on a track that rough, for that long.
My ideal goal is to 'recreate' the RX8 into what i feel it should have been in the beginning... 300 rwhp. Nothing fancy, no shiny pipes, no advertisements. Shoot, if i could reach that goal on a stock exhaust and without gauges in the interior, I would lol.

Oh yes I know sir... just waiting for my kit to arrive in the mail so I can forward the turbo to BNR for their upgrade. In the meantime I'm reading up, soaking up knowledge, and preparing for this huge transformation that I have committed to.
Getting 300WHP on a stock Greddy T618Z turbo is not likely even with supporting mods. My goals are similar even with an upgraded turbo. Aside from the gauges, it takes a keen eye to even know I'm turbocharged. I did not want gauges but in the end decided it is best to have them.
