Hey my brothers from other mothers

I should be getting my used OEM coils by this weekend. They were shipped out yesterday (express) so hoping to get them by this Friday Nov. 7. IF I get them is anyone around that would like to help me out with the install on Saturday? My car is stuck at my place, so anyone interested would have to come here.

Thx! This is still a maybe, depends if they show up, but wanna obviously get my car back on the road asap.

If not no hard feelings, I will just have to kick ya'll in the NUTZ!! :lol2:

Cheers!!

update Did a DIY in this thread on how to uninstall coils.

I have a tool kit, but many have broken working on my last car lol. It's at my buddies and have to see what tools are required. I don't think it takes very many, only like a 10mm wrench I think. Was kinda hopin if ThIef showed up he would bring his case again :) Will let you know thx!!

Dude it's along drive for you, so please don't feel like you have to!! Maybe the best thing to do is give me a ring or txt close to the end of your shift and I can let you know where I'm at.

HAHA funny fukin guy!! Dude if you go to the casino and get home at 8:30 I have NO prob's with you sleepin in :evil_laug

I luv my sleep so I don't know like 1ish. It gets dark so early now, so just want to make sure we are done before then. It doesn't seem like a big job. Have to remove part of my CAI tho.

what kind of intake are you using?

i had to swap out my coils at a dealership. i have the K&N intake so i could work around it. if you still have the OEM intake you might need to remove it to get to the coils. a ratcheting screwdriver with a long flexible extension with 10mm bit would really be helpful.

yeah... I'll make sure my calendar is clear for Saturday... I'll bring my tool kit as well (it never leaves the back of my car anyways).

See if you can get some instructions from somewhere... check the manuals (think there's a post in the DIY section). If not just get the aftermarket instructions from one of the kits... we'll just reverse the removal part.

I have the MS CAI, there is room, but not a lot. It's not a huge deal taking off the pipe with the MAF on it. Will just make it easier to work on it.

Thx man!! There actually isn't much of a DIY with clear instructions with pictures on the swap. Maybe we will make one :) From what I have read and such it doesn't look to difficult since I'm not even swapping the wires yet. Think there is only a bolt or two holding each coil onto the bracket. Unplug the plug wire and the wiring harness swap, plug back in. That's the theory :)

http://www.rx8club.com/showthread.php?t=131476&highlight=diy+coils Sorry looks like one bolt holding them on. Less work, but an extension ratchet will be best.

Will let everyone know one way or the other by Friday night if I get them. Thx again!

you pretty much have it. make sure if you remove all the wires to label them so you don't mix them up. i did 2 at a time so it wasn't too hard to keep track of but not much room to work with. my hands got cut up a little bit. the spark plug cables suck to remove BTW unless they used some kind of grease the last time.

oh yeah, the dealership didn't like it too much when i was changing my own coils in their parking lot.:evil_laug oh well saved me about $400 they were trying to charge me.

Cool man thx. I was thinking about doing just one at a time, but probably easier working from back to front when putting them back together.

I had new plugs and wires done in June of this year, so hope they aren't that bad to get off :)

Ya they were going to charge me $426 cad + tax. CRAZY!! I thought about doing at the stealership like you did, but was so pissed at them I paid to tow it out of there cause I didn't want my car near them anymore.

you should be able to get them swapped in less than 30 minutes.....it is a tight area though so you will scrape up your hands...........just be carefull when you put the new coild on you dont overtighten the nuts cause you will snap the bolts....they aren't very strong....then you'll have to pull out the plate, fabricate new mounts, get new bolts.....etc, etc......dont ask:)....it was an experiance...hehe.

I'm not liking this hand scrapping thing lol. What's working on your car without hurting yourself, just isn't the same. Thx Gecko will keep that in mind for sure! How come you didn't just go to home depot and buy the same size nut? It's just holding a very light coil on.

that is exactly what i had planned. can't wait to pull my plugs to see what they look like.

Hell ya!! The sooner the better. I'm not swapping plugs tho, mine are only 10k km old.

it wasn't the nut it was the bolt that snapped.....and they are spot welded in.....which means if you snap them the plate needs to come out, you have to grind off thehead of the bolt then find a replacement....also, I have big hands so I scrape myself all the time....but you are right....it would be working on a car with out hurting yourself....and remember...blood and oil mix:)

Hey anyone actually changed wires here before?

They are freakin tight on the coils, any hints at getting them off?

Gecko69
11-07-2008, 10:17 PM
I have a garage...but its in ktown.......the wires are on there well...just wiggle them as you pull them off.......be carefull though....if you are reusing the stock wires they have a spring loaded connector on the inside of the wire connection point.....if it falls out you just have to put it back in before you reconnect the wire...but just dont want you to drop it somewhere in the engine bay.....it will be lost forever.

11-08-2008, 12:02 AM
hey thump, when i did my wires, they were pretty stuck on as well to the tip of the coil...i've found if you kinda "peel" at one side of the rubber seal (part going over the coil connection) you can wedge the tip of you finger under the rubber cap and just go around the entire tip of the coil, after that it will come out nicely...all the heat makes those caps stick on pretty tight!

Well if ppl want, everyone that wants to can come here, we can basically take the whole thing apart so all I'm left with is wires then play some poker after? That way I only have to put the coils back in next week when I get the new ones and that won't be much of a deal after I get the current ones off.

Up to you guys, one way or the other, I'm gonna take it apart so I can swap it quick next week.

I have the original coils in my car now YES. I want to take them out, so when the new ones show up I can install them quicker and get her running again. Since Most likely I will have to be doing the install at night.

So for everyone that missed it here it is:

The 4 tools needed. The bendable elbow socket attachment work perfectly. Not one banged up hand :) I sprayed WD40 on all the nuts last night. Don't forget to disconnect the battery.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall0.jpg

MS CAI I decided to remove it. It could be done without removing it, but wanted more room to work and easy enough.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall1.jpg

The ignition coils being removed, still with the plugs and wiring attached.

CAI removed.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall4.jpg

This nut was a bit of a problem, as you can see with the main lead wire right next to it not much room to work. That plastic strap holding it comes off I'm sure but didn't want to screw around with it. A 10mm closed ended wrench fits in there with a little work.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall6.jpg

Also unclipped this wire since it is in the way of one of the wiring harnesses and the rest of the wire gets in the way. Use needle nose pliers to pinch the back side and pull out.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall7.jpg

Now just pull the plugs off and wiring harnesses. I labeled them with tape, but make sure they are labeled so they go back together the right way. TIP Yesterday I was having trouble getting the plugs off the coils, RotaryGreg and phobi mentioned to just run your finger in and around the rubber part of the plug. Basically the plugs with age, heat, etc...are just seized on. You can kind of hear the plugs peal off the plastic coils and pull. Very easy and you don't even have to pull that hard. Thx RotaryGreg and phobi!!

Now that every thing is unplugged, use the 10mm socket, with the elbow and extender, it fits onto the back 3 coils with no problems. Use the closed ended wrench and take off the first one. Be careful not to lose any nuts. And then you have this.

http://i61.photobucket.com/albums/h76/silverbullet33/RX8%20Ignition%20coils%20install/coilinstall10.jpg

My coils, second picture you can see all them had the white spot on the bottom except one.

Thx Greg! No worries man as you can see wasn't to difficult and now everyone should be able to do their own with no problems. Everyone will have to make it out for the BHR kit install, since it is a little more work and replacing the wires is a little tougher. That's a shitty way to spend the day lol.

Got my used OEM coils tonight. Hurray! Installed and she is alive again. But man was she smokey. I'm guess it is from the new CAT?

I let her idle for awhile before I went for drive. Hit the hwy and wot up to 4th redlined the whole way, and got a CEL :( let off the gas and the CEL went away. Turned around and came back down the hwy wot, no CEL but felt a bit of hesitation in higher rmp. Drove to my bro's house and back, some 1s and 2nd gear wot and all seemed good. Will see how the next few days go, since the computer has to reprogram I guess. The upgrade is gonna be nice!!

11-12-2008, 08:43 PM
ya marc, glad your back on the road. that first time when you had the CEL, was the car completely warmed up? like no doubt about it at operating temp before you went to redline. just wondering. mine was getting sort of finikie lately, if it wasnt 100% at operating temperature when it was cold outside, i would miss when i got on it. if it was really cold it would happen as low as 4500, when it was almost at OT, it could happen as late as 8000rpm. I changed my plugs and damn, what a difference. i can start the car and slam it in gear and go no worries now (i dont make a habbit of that, i just wanted to see if it was really the plugs). i know you said you just recently changed the plugs, but it might be worth changing them now too. after all that missing from the dead coils the plugs are bound to be fouled up pretty bad. Although, if this CEL was a one time thing and it doesnt happen again, then i wouldnt worry about it. if you want to do the plugs, let me know man. im sure i can help you out there.

Greg

also, can you be more specific about the smoke? where was it coming from, smell, colour?

Thumper3322
11-12-2008, 09:09 PM
Ya once i got her started (and she started right up), I let her idle for I don't know 15 minish, she was at normal operating temp. via the gauge, drove up to the highway and hammered it and got the CEL.

Good to know about the plugs! I was wondering about them myself, after everything my car went thru, it couldn't have been good on them. I feel like I blew $500 bucks on plugs an wires a few months ago now. That would have been the only reason I would have paid Mazda to do the coils for me. What a JOKE can't believe $426 for that job.

Been talking the Charles Hills bout the coil upgrade and he has a great deal on plugs so I might be picking some up anyways. And the upgrade comes with new wires so all is good. Ya, Thx!! I would need help with the plugs for sure, never done them on the 8. Love learning more and more about the 8.\

The smoke, thicker black, stank smoke. No blue or white. Again new CAT so could just be from that? It was much much less when I got home, could only kinda smell it. Will be keeping an eye on that as well.

rotarygreg

alot of exhaust parts come shipped with stickers on them that usually dont get removed upon installation. that could be some of what was buring off, unless you mean the smoke was coming out of the end of the exhaust...hmm...

and as for doing the plugs, not hard at all. it took me 10 mins to do on my hoist at work. could be a bit of a pain on your back though, the front leading plug you need to use a wrench for because of the way the motor mount is, so you have to be really sure your on it good or you will round off the edges of the plug and then you wont be getting it off period. the front trailing plug is easy enough if you crank the stearing wheel all the way to the right before you shut the car off, then use a really long extension and go in from the wheel well. both rear plugs are cake and no special tricks needed. although i dont know how easy this would be without a hoist. seems like it would be a huge PITA.

I should correct my other post, wasn't too black, more grayish, but more than normal. Seemed much better this morning. Car started much faster as well.

10min eh lol...and they charge an arm and a leg for that as well. I figured as much, taking off the wheel and the inner liner to get at them. Always wondered, do you have to space the plugs? I think that only goes for two plugs, or do they always come spaced properly.

if you buy the plugs from mazda theres nothing to do but install them. two plugs have an L on them for leading, and the other two have a T on them for trailing, but the electrode end of the plugs looks very different from eachother so theres no question which goes where if you pay attention when you take the old ones out. for the record, leading plugs are the bottom two, trailing plugs are the top two. also, you dont need to take the wheel off or take the fender liner out. you just need to turn the wheels all the way to the right. the fender liner isnt in the way at all.

I wouldn't be buying them from Mazda, from Charles Hill instead. No shit! Well if/when I do them, then maybe you can come show me. You didn't answer my question tho. I have seen what they look like and two of the for look like more of a normal spark plug. Do they come spaced correctly?

BTW...my car is running sweet now! :) Hammered in getting onto the 401 again 1-3 rdline the whole way and no problems at all. So glad she is back :) Thx again for everyone's input!!

sorry, the mazda plugs do not need to be spaced. period. thats why i like them. i trust them. i dont know about charles hill....if his are just mazda plugs then i would assume no spacing necessary, if they are RX7 plugs then ive heard they need to be spaced. with a car as finicky as the rx8 can be, im not inclined to buy spark plugs from anyone accept mazda....they have the rights to the plugs the rx8 needs for the next couple years at least, so everyone elses plugs are just the next best thing IMO. i havent tried the others myself personally, but it seems that way to me, i have my reasons.

Cool thx for letting me know and your insight on them. I haven't decided yet, and no idea which are better, but no bad reviews yet on his plugs. My car is running sweet right now, will probably just keep my current plugs goin, and do the upgrade.
