I tried but wouldnt work with neo head. Perhaps my coils were slightly different. Ended up mounting then on the exhaust cam cover using the gm leads.

You have to set your dwell correctly or it will misfire.

Yes. I used stock coil boots and modded springs. Currently supporting over 500rwkw

What head is that?

If the yanks can do it obviously we can.

RB26.

Honestly the hardest part was working out how to make the brackets. If I had a tig I would weld some rod from the sides of the valley and tap a thread into them, and secure the coil packs with a bolt.

This is cool, can you give some more info on how you did it?

[Mitchee]

There's really not much to it.

Use the boots and contact springs from stock coilpacks (i think i had to stretch the springs slightly), sit the coilpacks where they are happy and have good contact with the plugs, then make brackets to hold them in place.

From my build thread:

Had a couple of hours today to dick around with the coilpacks..

Grabbed some old boots of some stock RB coilpacks and found they fit nicely over my LS2 truck coilpacks I have. Standard these are a 'Coil Near Plug' which means they are designed to have a small lead from pack to plug. With the contact spring pulled from the RB coilpacks, stretched slightly, they fit perfectly over the electrode in the LS2 coil so I can run these on the plugs. The contact spring compresses about 5mm once the coilpack is in place on top of the plug. Should work OK. I wrapped some electrical tape around them just to keep them in place and give it a bit of strength.


Heres how they sit.



And some brackets I made up which will hold them all firmly in place, just need to pick up some more nuts and bolts.


Also received notification today that my Tomei Procams and Supertech stuff is on its way from the states. Stoked!!

^ how bout wiring ?

[Ben C34]

Wiring is easy. A quick search gives you all the info you need to do it.

[Piggaz]

How much power are you after to warrant this setup?

[Ben C34]

I did it because the ls coils are heaps cheap ( I got mine for nothing) and a bit of wiring and some brackets takes no time.

[etang789]

If you cut the stock coil boot shorter can you lower the LS2 Coils enough to fit the stock coil cover back on?

This is funny. Just today my father was mentions this to me. Now im seeing it here. Well what are the advantages of going with a setup like this. Is it cost.

Cost. They are heaps cheaper.

Somewhat performance. They are substantially more powerful coils. But guys make big power with stock coils so that's not the main reason.

The dwell needs to be set higher (5ms) or else they won't perform as well as stock coils.

Aren't you in the states? They would be cheap as over there.

Here we can buy 8 new coils for 280 aussie dollars.

I have them in my neo, using stock ls leads they are mounted on the exhaust cam cover.

Yes I am in the states. I figured that it would have been a cost thing. But compared to the stock GTR coils what your saying is they are a way better coil performance wise and obviously cost wise. Im running a power fc in all my cars so I should be able to set the dwell settings. Im going to need coils for one of my build. I willing to give this a try. I also ahave a tig welder. So making the bracket to hold them down would be easy.

[Ben C34]

Yep I think it's crazy to buy oem coils.

The ls coils are so easy to wire up and way cheaper and better!

Why wouldn't you want that?

Status explains which coils to get and why.

[etang789]

This kit looks like it would be an easy plug and play kit!

someone did this in canada on stock tune , no problems. not sure how good it works w/o adjusting the dwell

[Ben C34]

When I did it before adjusting dwell it would miss fire above 15psi
