SBGarage, have you looked at/into the Series 2 RX-8 Coil Backing Plate as there are some differences, not 'how' 4 OEM Coils install, but the S2 plate has a few extra brackets extended on it for large wiring loom support and other. (don't know if you have compared the two different coil plates and if the mounting of yours would have any issues, just throwing it out there).
If you want to see pics of S2 Coil Plate front and back, let me know.
Apart from that should be great for all Series 8's.
If you get a chance and want to send us a PM or even just post in the thread, we'd love to compare the two. This bracket bolts to the AC compressor and one of the stock coil pack bracket locations, and for those of you that don't have AC, we'll provide spacers.
We've also added some provisions to rivet on an optional heat shield. We can also try to add whatever's necessary for the harness mount, but space is limited
Here is a pic of a new S2 RX-8 Coil Bracket I have, I don't have a S1, however as I said OEM Coils mount in the same positions (same coils), the changes to the S2
Coil plate/bracket is the heat ridge/gap down the middle and the end bracket (above my user name), I think that is about it...?
I recall a few S1 owners buying a new S2 bracket and it needed some mods to fit on their S1, I cant exactly recall (was not much).
IF you don't use this Bracket at all then this is a moot subject?
BTW: Mark, when I say I have any new S2 parts in forum, I physically have it, not just 'the' or 'a picture'. Remember this background cloth (sarong),
so you know it comes from me physically.
We're actually making a completely new bracket, which only uses one of the stock mounting locations, but it's definitely good to see the S2 bracket. I did a look-over and the mounting locations we're using don't change chassis to chassis so we're good But it's always good to confirm.
And now for the good news:
We really appreciate all of the interest and enthusiasm with the RX8 IGN-1A setup. We didn't expect to have so many email requests to purchase immediately. While this kit will cost a bit more to produce than the RX7 kit we currently make (additional plug and play connectors, and a larger, more complicated bracket), we were able to get the full kit into the same ballpark as the RX7 setup.
Retail will be $725, but we'll run a pre-production group buy sale on them for the first 15 people interested. We're only producing 15 kits for the first run. You can go to the following link to pre-order the kit. As soon as they are back from production, we'll ship immediately. We're guesstimating a few weeks, assuming everything goes to plan. We just submitted the order for our production run of brackets, so those will be getting here soon.
Please add your name to the list if you're interested in being part of the pre-order / group buy, and please mark yourself as paid if you submit your order.
Thanks again, and please feel free to ask questions if you have any!
I can't answer that currently, as we haven't tuned a turbo RX8 on the dyno. If you're experiencing ignition breakup, you'll need to increase dwell time, but that depends on the capabilities of your ECU. Without one on the dyno, we can guesstimate at an appropriate dwell time table based on the RX7 maps, but it's very much application specific. If you can't adjust dwell on your ECU, the only way to find out if the stock map will work is to try.
You'll want maximum dwell at peak torque, and to go easy on the coils, the best bet is to ramp up to that dwell as RPM increases, and taper off after peak torque.
The coils are massively powerful, and can put out the same energy as BHR in less time, or more energy in the same amount of time. More spark energy should mean more complete fuel burn, and more power. There is also a longevity argument, because these are deigned to be run on shorter dwell times.
Hopefully those that own the coils presently (and have done their own DIY work) can chime in and give you better info.
from a longevity stand point utilizing stock ecu tune, these would last at least as long as BHR?

Thanks so much for the reply
Without a 9ms dwell time they should last indefinitely. Just a heads up to everyone, these are not light coils, they're nearly 1 pound EACH. They're built for war. The large windings/oversized magnet, and top notch engineering on the internal charge control board allows for a very fast recharge time, unbelievable power, and great stability/longevity.
The coils also incorporate a sensor ground/reference ground which we have optionally set up on our harness (for high power applications) which will account for voltage fluctuations from the alternator as they constantly reference a known "zero" for ground (generated by the ECU). It's what keeps sensitive sensors accurate in a noisy electrical environment, and allows the spark output to remain extraordinarily consistent.
I have a PFC on my FD and I set the dwell at 4.5ms constant except for the leading which goes down to 3ms or so at redline due to waste spark
Coil settings for the RX8 did not seem to change between generations... can anyone confirm this?
For the FD running a Power FC I recommend this table (this is PFC set up for waste spark (obviously). You/your tuner can always tweak them from here if you're making a ridiculous amount of power and getting ignition breakup, but this is a really good starting point.
I don't know what to do ! I really want these -but are they overkill on a stock 8 ?
I do need coils as they've never been changed.
What to do What to do.....
We just got the prototype bracket finished and are gearing up to do our full production run. We've already got a bunch of pre-orders in, first come first serve, and we should be starting to ship in 2-3 weeks or less.
All done. We've got a production run in full swing. To purchase a kit at pre-order pricing please click here (8/15 kits left). After this first run the price will return to the standard retail price but we'll have them stocked
