LS2 Coils and N/A
 

Hey Guys,
I want to do an upgraded coil set up because I feel the coils will need to be replaced soon. I was wondering if anyone has run the LS2 Coil swap on NA? Is there any benefits or should I just go with a BHR kit? Money is tight and I'm looking for the best route to go on a budget.

They will last longer that's for sure. Buy 4 D514A coils, RX-8 Harness to LS2 Coil Connector (ebay), make yourself a bracket and make your own ignition wires . Done deal

Those aren't the same coils that BHR uses in their kit.

I know they use d585's, chose your poison.

once to buy known good coils, all the correct connectors, sparkplug wires ( you will have to make yourself), harness and mount you will find that you will not save that much money. You will save a little. But you will have to wonder if it wouldnt have been better to just buy the kit. Be careful in buying coils--dont go to e bay and just buy anything out there.

Thanks guys really appreciate it. I think I will just go with the BHR kit. It will just be easier to put on in a weekend.

My DIY D585 coils. Went with simple bracket that provides better cooling. Not shown are the MSD plug wires. Total cost about $375 with new plugs. Two hour build, but I designed bracket on the fly.

Very good craftsmanship. What does the rest of the bracket look like? What cost and time do you have in it?

oh i reused the mazport bracket i have

Let me know how the D514A Corvette coils work. I thought about that, but went with D585. They seem to be the most popular here.

hmmmmm - I have one of those gathering dust in my gge as well .....

this is what i found....


The LS2 coil (GM# 12573190, AC Delco D514-A) from:
2005-2006 Corvette (& GTO and Avalanche)
2002-2005 Cadillac Escalade
2000-2006 Yukon
1999-2006 Chevy Silverado
2001-2005 Trail Blazer
Some Hummers, etc.

The model is GM# 10457730 or AC Delco D585 (also Wells C1251, Standard UF262, GM/Daewoo 190005218). The LS2/truck coil has a visible external aluminum heat sink near the connector.

These LS2 coils are incredible. Even compared to the LS1 coil, these are just crushers!

On the LS1 coil there is around 40 milliamps of peak secondary current with 5 milliseconds of dwell time.

On the LS2/truck coil (AC Delco D585), there is 120 milliamps!

I just installed the d585 coils with home-made wire with 45deg boots and they work fine, but I twisted the coils to suit the 45 deg boots.

taylor list these as compatible 90 deg boot.
Taylor Part # 46067

The wire challenge is not the angle, it is the LS2 connector. MSD and others make the correct plug wires.

i got this ones and they are working just fine

My coils cost me less than 80 and comes with lifetime warranty?

well coils ,harnes,spark plug wire total of 322.00 with shipping!!!!!:naughty:

Where did you order the harness and plug wires from? Break down the $322 please because that's a significant savings over BHR. For that price I will order it today!!!

pm'd

sorry is not 322.00 is 301.25 total with shipping

ls2 swap dwell ?????
 

Can these just plug and play as far as the dwell is concerned?

Reviving an old thread... but why won't the stock ngk wires work on these coils? I've heard that 12a spark plug wires do work however. Anyone tried this before?

stock wires wont work because the coil connector is different. I currently use wires from a 05-07 Ford F150 V6. If you are handy with a flat blade and crimps you can shorten the wires to length.

Found this bad ass bracket thought i'll share. Search eBay lsX coil bracket

Holy shit, i'm glad someone revived this thread and you posted that. i've had the coils/wires/ Pigtails for like months and just been too lazy to make a bracket. Going to get on this now though

thanks!

Where can you pick up the coil connection kit if you want to piece this together as well? I was given a brand new set of ls2 coils and won't have to buy any of them so I think piecing together will be the least expensive route

Where can you buy anything on earth? eBay of course. Lol

@ linuxadickt -- First you SN is GREAT!!! Now on to your find do you know if it will fit the stock location? Either way man what a great find I will be picking on up for my LS2 kit!! Nice work!! I wish I could give Thumbs up!

Hey Sebarx8, where did you get these? did you make them?

I've built my own ignition wires before using MSD parts, that's easy. A quick eBay search didn't turn up a cheap source of those coil plugs though (ignitor/ecu side). :/

Here they are.

LS2 Yukon Ignition Coils to RX8 Harness Adapter | eBay
I used them with D514 coils and wires of a 05-07 Ford F150 V6. The wires you can shorten if you are handy with flat blade screwdriver and crimps. Still have them in a sloppy row zip held together with allthread and zip tied in place. No hot start issues, and worked fine with stock dwell. Hope that helps somebody.

May I have this info aswell.looking to order

Google is your friend.

Has anyone used this bracket?

Google is not reliable nor has google bulit a rx8 but thanks for that useful information

The 2nd post on this page tells you exactly what parts you need. Use google to find the lowest price for said parts. A little reading goes a long way.

where can i find these D585s, there expensive as hell for authentic AC Delco, 75-119 bucks a piece. im scared to do the swap if im gonna have to spend 400 bucks to replace coils in the future. Are the benifits really worth the expense? if so, how?

Just buy the BHR kit and you won't have to replace them in the future.

A DIY kit is very close to the price of a BHR kit, and the BHR kit uses the right coils, is plug and play, and has excellent customer service.

BHR uses a D585 derivative coil. Just buying a set of D585 coils will NOT get you the same thing, as they aren't ideal for use with the RX-8

Yeah I was wordering where you ordered the premade wires and the RX8 to LS2 harness?

Posted already, read up the page.

What do you mean exactly when you say they are "derivative"? I thought they were the same?

I can give you a great deal on the Brooklyn Bridge too

I can't seem to find what I am looking for so I figured this would be a good place to ask, does anyone have a wiring diagram for the actual harness between the rx8 ignition harness and wiring up the ls2 connectors?

as attached, note the position of the "tab" as shown on both the connector layout and coil itself

and in response to the deleted post by another member, why do I need the specs of any particular smart coil when it can be tested directly? Aftermarket specs being different than OE is nothing new, quite common actually. The real key is modifying the dwell map properly, even on those particular coils as I've done many times.

And adjusting dwell is from good edu management such as adaptronic and microtech? Or will even just a Cobb do? And thanks for the diagrams btw team

alright so I have been looking and I cannot seem to get the wiring right. I got the ground hooked to the battery, but as the order of wires into the order of the pugs on the harness of the car I cannot get it to fire. any help of the full wiring harness for the d585 coil would be appreciated.

Probably should have pointed out that you can't assume that the A - B - C positions on the RX8 wiring diagram match the coil. You should have compared the wire color positions on the wiring harness coil connector and wired accordingly. All of the B position wires are solid black (B) and all of the C position wires are black/white (B/W) and the A position wire color varies by the coil position due to that being the signal wire to fire the coil. I'd recommend running the new common ground either to the battery post or to a ground point connected to the battery post.

Also would recommend buying the harness on ebay for $100. Its a quality piece, better than any of the kit harnesses I've seen ...

Cool I see what you mean I will look at that when I get home from work. Do you happen to know a link to where I can buy the male plugs that plug into the harness on the car? I can't find them anywhere.
