Hi what is involved in fitting Split Fire coils to my R34 GTT. I have searched with no success,is there link to a do it yourself guide,or am I making mountains out of mole hills. Are they a stright swap with no wiring mods

Any "polite" assistance would be most grateful

Cheers

Steve

Ps The problem is I have lost my voice permantly due to cancer so I can't just pick up the phone and ask

I Have only changed them in my R33 Gts25t, but I would assume its the same process for changing them in a R34 Gtt. It is fairley straight forward. There is no re wiring needed. They should plug straight in. I believe I have a walkthrough some where or I have seen one. I will try find it.

I found this one. This is on a gtr but the process should be very similar for a R34 Gtt. Will just need to remove the cross over J Pipe. Also the R34 Gtt Rb25det uses different coils as they do not have a igniter box like the earlier rb25det's, rb20det's and rb26dett. So when you buy them just make sure you get the correct ones. The Splitfire coil packs do come with instructions but they are in Japanese. They do have pictures though which are easy enough to follow.

Mate I mean this in the politest way possible. If you have to ask about swapping coil packs then you shouldn't be swinging spanners on your car. I say this because it is one of the simplest things to do on a skyline. If you open your bonnet then it would be plain as daylight to see what you have to do. If you have to be walked through it, you are going to need someone to check it afterwards to make sure its reassembled correctly. As far as splitfires go I wouldn't waste my money if the car was to remain stock. If you intend to make a crazy, scary, don't lend this car to your mates kind of skyline then do get them but until then don't waste money. The oem parts will do fine for a completely stock car. If you are in the Perth region I'll come over with my tools and show you how to do it. For free.

honestly as long as you're careful, take your time, make note of stuff as you pull it off and store any nuts and bolts carefully (a, so you don't lose them and b, so they don't fall anywhere they can damage stuff) you'll be fine.

it's a pretty simple job. nothing wrong with being cautious but I say give it a go. you can always ask for help if it's not going right. :)

Don't worry about nathan he must be in a mood. Definately have a shot at changing coils, save ya self some cash.

Here is a link on changing plugs on an earlier RB25det from a R33 Changing plugs on RB25DET

Definitely go Splitfires too as discussed in your other thread. Not a waste like nathan says. Leaving your shagged coils in is a waste of money

You will have an engine cover and as said will not have ignitor module on top of coilpack cover as some earlier models have. In this tutorial I believe the coils are removed on their mounting bracket together. Instead or removing them all together you will find screws on the coil packs hoding them into the bracket. This way will be better for you. You could get some spark plugs for peace of mind and convenience while your doing coilpacks.

Bahaha. Thats right don't worry. I sound more cranky than I am. I'm not saying leave the stuffed coils in there. I'm just saying that splitfires are twice the cost of stock ones and if the original coils lasted 15 years then new stockers will last another 15 years. No doubt splitfire are better for high performance but simply aren't necessary for a completely stock car. Of course if money is no issue then get the splitfires. I agree with changing the plugs at the same time. I disagree with leaving the coil housings in there and swapping the coils individually. Way to fiddly and likely to drop the little screws in which case would have to remove the lot anyway. I recorded a youtube thingy in which I remove and replace the front 3 coils with one hand on the camera and one hand on the ratchet. I'll add it when its finished uploading. At the end of the day its just advice. You don't have to take it. devil.gif

just a tip, be VERY careful when you are removing the old coil packs and putting the new ones in, the little 8mm bolt can easily fall down and make its way into the timing cover from the back where the timing belt it, if that happens then you have NO choice but to pull appart the front of the engine to take it out, depending how far it goes down. Have seen this happen alot.

Also when you are putting the coil packs in, dont dive in and remove them all in one go, because they all sit a different way, (the plug for the coil loom sits facing the front of the car or the back of the car) disconnect one and make sure which way it goes put the new one in and plug it in, then move onto the next one.

this is not meant to scare you in anyway, just something to look out for so you dont get in trouble.

good luck

This is sound advice. They are good reasons to pull out the coil packs in their housings and do the front 3 one at a time then replace and the back 3 one at a time and replace. Can you imagine a little bolt poking through your timing belt? Yuk.

I am sure that if stockers were half the price of Splitfires there wouldn't be many splitfires sold. OEM coils from Nissan are over $1000 a set here. Can you point me to a good price source for OEM coils - even at the same price as Splitfires I would buy them.

Ok not quite double. The price has dropped a fair bit since I last checked.

Stock coils: http://www.ebay.com....5#ht_500wt_1156

Splitfires :http://www.ebay.com....#ht_2706wt_1139

EDIT: Splitfires aren't comparable to stock coils for price. They are better and cost more. Are you going to put $500 a tyre semislicks on your missus hyundai?

And why would you buy a stock coil for the same price as a splitfire coil? Thats like being offered $20 for free and $50 for free and taking the 20 cos you like the colour red.

Thanks for the link. I'll try to get me an OEM set.

Are you sure? There has been a lot of discussion about this over the years and there is no clear evidence that I have seen.

I'd like to make a bet that new coils OEM or Splitfires will produce the same results.

    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
