For those of you who haven't been following a few other threads I have been posting in, I have been working on a DIY LS2 ignition installation and finally got around to installing it yesterday. Here are some shots of my work:

Nice .... now get back to work

 

well done paimon

 

i love you guys

 

how are you grounding them?

 

the harness has a ground running from each coil to a single grounding wire. That wire is grounded to the engine's ground point right above the coils.

 

Bravo, monsieur!
I've just enjoyed another episode of "Paimon Presents..."

How tight is the fit in the engine?

 

oh it's in there nice and snug ... took me a hell of a time getting in since the mains harness runs right around there. But i use all the same mounting holes as OEM so it is bolted in there and doesn't move around

 

haha, derp derp derp, you would think I would have seen that

 

can we know how much it cost you in parts ??

 

I managed to get the coils at a really good price (100 total for all 4), and then the wires and boots cost me a total of roughly 100. Throw in the sheet of aluminum and the screw dowels, and i would say about $220, and if you throw in the OEM coil bracket it would be a total of $260

edit: forgot to throw in the RX8 -> LS2 harness which was another $100 .... so we are looking at about $360ish

 

don't forget the PnP wiring harness cost

 

^ aha! thanks, edited the post

 

Where'd you ground yours exactly ? Others told me to ground on the driver side somewhere. But my PnP wiring harness was long enough to routed directly unto the battery's negative terminal.

 

there is a bolt right above where the coils are. There is something already being grounded over there, so I just tapped into that.

 

eventually you will need this too, regardless of coil/wire type

Beautiful little tool that is a mainstay in my toolbox now. That was an awesome DIY Team that helped me diagnose a bad BHR coil. (Which Charles promptly replaced!)

 

does anyone know what the S2 dwell tables show?

 

This is more common than people realize. It does not get discussed openly much. I developed the DIY troubleshooting a brand new BHR assembly that came with a bad coil. It was promptly replaced once I brought it to their attention. There is no magic at work here. These can fail no different than an OE coil for all the same reasons.

Unless they have access to the OE map how would they and why would it matter when there is no tuning solution to access and change it?

 

What coils did you use. D585s? Where did you find them at that price!?!?

 

D585s and i got them from a member here

 

Damn!!!! I'm trying to hunt some down

 

Forgive the ignorance, but what is the advantage of using LS2 coils? Higher output voltage/current? How does this compare to BHR's ignition kit?

 

looks great!!! so you cant use rx8 8.5mm wires?

 

if you don't adjust the PCM dwell table they make less spark energy than the OE coils from around 5000 rpm to redline
