Build your own D585 Ignition System - Save Money

Recommended Posts

Hi all,

 

If anyone out there is thinking of going down the D585 setup and you don't have the €450 plus to spare, why not build your own rig? I did.

 

Below are links to where I made my purchases, Total cost €196.21

Made my own bracket.  Cost less than a €10. Woodies DIY. Based on Bennetbuilt Performance Bracket.

I've put a photo of them in the Gallery under Member Cars "Carl (Chazz) RX8"

 

Coil Packs 4 x D585 - €89.62 (Depends on US$ Exchange rate on the day) includes postage.

8mm Ferroflex D585 Leads – €48.50 (Depends on STG£ Exchange rate on the day) includes postage.

Link to his eBay Shop. NOTE: this guy makes them himself, so they’re not cheap Chinese knock offs - Mr-Retro-Leads-Plugs

D585 RX8 Harness Adapter – €58.00 (Depend on US$ Exchange Rate on the day) includes postage.

If you don’t want to have a go at building your own bracket you can get one from Bennettbuilt Performance.

Below is the link to their Bracket. €102 (Depends on US$ Exchange rate on the day) includes postage.

So buying all the parts yourself from various suppliers above, (NOT building you own bracket), will cost approx. €298.12 – again, depends on the Exchange rate on the day.

You could buy the complete kit from Bennettbuilt Performance for €363 includes postage.

Either way you’ll save €€€€€€’s

 

That's all Folks! :)

Addition to the above as it won't let me add, something to do with image extension not being allowed.

 

Anyway, if the above coil pack supplier is out of stock here is another one. Little more expensive, but still a saving. ;)

 

Coil Packs 4 x D585 - €112 (Depends on US$ Exchange rate on the day) includes import tax and postage.

I've been thinking about the above Chazz since I got the RX and now these 969's are about also making the decision harder again. I think I'm waiting to see more info (& cost) on the 969's before making a decision, I know the D585's would do fine but what if...... the next RR version have something a little more special! :(

Great DIY guide Chazz, thank you!

 

Yeah, the 969 were developed with racing in mind plus I don't think the dwell time map is the same as the 585s, all we know so far is they work better than the 585s with the stock map but their map is still a work in progress.

Are the harnesses for the 969 & D585 coils the same? And do they mount in the same way? (i.e. are they interchangeable)

 

Also, anyone got any sites that sell them cheap like Chazz has posted above? :)

As far as I can tell the harness is the same, but the leads are different. For D969's aka R969's they use the 10mm Magnecor R100 leads.

The 969's don't need the dwell settings changed as the setting are the same for the stock Mazda coils.

The 969's have a lower dwell than the original coils meaning they will charge quickly and run quite well on the original map. HOWEVER, it should be noted that when on the original map they become fully charged 1 milisecond sooner than the ECU expects and can cause either overheating or worse massive current draw (much more than original wiring can cope with)

Rotary Revs are the only ones' selling the 969's. They designed them. Not available anywhere else. So if you want 969's you'll have to buy from RR. ;)

As in they designed the coils from scratch?? Are they not off another GM engine? What're their benefits over the D585s?

Yes, to the 1st and No to the 2nd question. Not really much as far as I've read on the UKOC. Will post more info later.

Okay JP, here's more on the question you asked.

 

The D969’s also knows as the R969’s have the same design and mountings as the D585’s and the same bracket. The dwell setting are close to that of the standard Mazda coils.

 

What I’ve gleamed from elsewhere is that:

“The specs are different in that after only 2.6ms of charge time they will output a spark equivalent to that of the D585 standard charged for 5.5ms. That's a difference of 73mJ of spark energy delivered at 40kV”.

 

Now what Jamie (littlefeck) above said, is food for thought. Personally I’d stick with the D585’s and a mini map. They’ve been tried and tested over a good few years now.

I’d wait a good while to see what the guys running D969’s have to say about their performance :mellow:​

Hope this helps ;)

Agreed, nobody wants to run on cheap coils, sparks, plugs etc., but there is a difference between value for money and being ripped off.

If one does their homework on suppliers, one will find out the good from the bad.

 

A case in point on spark plugs for example: €161 for plugs I paid a reputable Motor Factors in Dublin not two weeks ago.

The same plugs can be got for €83 approx. from hadlowj on the UKOC.

He also sells them on his eBay shop for non-UKOC members for approx. €94.

So again, not all eBay sellers are shysters!
