Seriously?

Are you going to be able to get it done?

Here's what I ended up with. I used the GM bracket and mounted it to the firewall. Taylor "409" wires, $80. I cut and installed the coil side plugs myself.

Gonna go ahead and do this. Just ordered a "bank coil assembly" form ebay for $43 shipped. I asked seller what is included and he said 4 coils, the bracket, and the harness connecting them. Mine have 106,000 miles on them. Now I see an auction from the same seller for the same thing only $35 and 75,000 miles! Certainly worth a try.

D581 coils are dogshit coils, I will give you trees of them for free.

If you buy anything off a LS truck, it needs to be a D585.

Early E85 flex 4.8/5.3's and 6.0's, then I think all 6.2 trucks?

My 2002 LM7 came with d585's.

I don't know for sure, but I also don't think the coil pinout is quite the same. If you want to switch to LS2 style D585's you might need a new truck side harness.

The truck ignition coil upgrade - LS1TECH

Relevant info in one neat post here.

Hurray for not dogshit

Not sure how accurate but at least they are a few different vehicles and year ranges.

You guys think there's a way to test the coil out put? Say you had 4 and tested them and found out one is noticeably less than the others.

There are a few variants of LSx coils, bbundy has posted pics and part numbers here.

GM#12573190 ACDelco D514A LS2/LS7 Corvette:



GM#10457730 ACDelco D585 LS2 Truck:



GM#12611424 ACDelco D510C LS?:



GM#12558948 ACDelco D580 LS1/LS6:



The general consensus says the LSx truck coil (D585) is the best, followed by the non-truck LS2/LS3 coil (D510C, D514A), then the LS1 coil (D580). I'm sure this isn't an exhaustive list of all LSx coils but these are the common ones people are running.

If you want to use the FM bracket, you'll probably want the D510C.

They are all much beefier than our OE coils or the Toyota coils.

Mounting

You can buy the D510C LS2 mounting bracket from Flyin' Miata for $44.95, part # 26-04320. The part # for the Magnecor 5mm leads is 26-04075. These parts suit 1994-2000 cars (non-VVT). You can buy additional parts from Flyin' Miata to replace the VVT hard line to let you run this bracket on a VVT engine.

The instructions for their full kit can be found here:
http://www.flyinmiata.com/support/in...ra%20coils.pdf

Keep in mind that the FM mounting bracket won't work with the EGR pipe in place, and may get in the way of coolant reroutes.

Wiring

If you are retaining all the factory wiring you will need to wire these as wasted spark:

A - grounded on engine

B - existing ground wire on coil connector loom
C - existing trigger wire on coil connector loom (trigger wire on coil connector 1 goes to both 1/4 GM coils, trigger wire on coil connector 2 goes to both 2/3 GM coils)
D - existing +12v wire on coil connector loom

These coils don't provide a tach output.

Here is a wiring diagram from swimming108:



Here is a schematic from Megasquirt Sequencer Coils:



Dwell settings and optional capacitors

Taken from Megasquirt Sequencer Coils:





Disclaimer

None of this is my work, I've just brought together useful things found on this site. I haven't tested anything above first hand but have tried to verify everything from at least two sources.

Please post the type of coil you are running and how you have things mounted and wired!

Cheers
thank you for the everything! however, one question, how can I know which connector is the coil1 or coil2 from that 2 factory connectors

Connector 1 goes to cyl 1/4, use wiring diagrams and wire colors to figure out which one goes to which.

thank you. and is it ok for using LS coils on stock engine? I mean, can I install them when I get them in hands, or I better wait until I can install them with all the upgrade (turbo, injector, etc.)?

They'll work fine with a naturally aspirated motor, so long as you have an ECU you can use to set the dwell properly. Don't try to use them with the stock ECU.

MS3 and wideband should be the first power mods you ever make.

In March I did some DIY anodising of FrankB's aluminium overflow tank and figured I may as well anodise my D514A brackets too since everything was all set up.

From this:


To this:

Note: Portside bracket base is shaped since it looked too chunky when straight, starboard base is straight since it's almost hidden from view,





You can see details of my DIY anodising here: Lokiel's "Gina" (2004 Titanium SE) - Page 47 - mx5cartalk.com

It takes a lot to set up so it's a good idea to plan on doing several pieces when you do.

The results turned out far better than I expected.

Why anodise aluminium?
Anodising produces a hard surface that's less prone to scratching and staining.
Looks good!

- unfortunately the anodised coolant tank and D514A brackets make my Wrinkle-Black painted air box look ordinary so that's next.

My anodized Turbosmart BOV looks all sorts of shitty
