Ls2 Coil Conversion Guidance

[xashskylinex]

Hey up firstly I very sorry if this topic has already been discussed but me I can't find a clear answer to what I want

Ok I have a rb28 and always having issue with my OEM spark and coils now I have seen online people have done the ls2 coil swap can someone guide me to what LS2-7 coils I need and the wording diagram to do this swap ??

Also this coil swap would it be compatible with HKS F CON GOLD ECU

THANK YOU

D514a coils fit BNR34 ?

How about rather than bumping this thread every few hours when you don't get a response, get on google like everyone else has that has done this mod.

D514a coils fit BNR34 ?

Well yeah, they will fit in the engine bay somewhere. Clearly the pic you quoted has the coils mounted in a non stock location.

JH32 I'm sorry if bumping the tread hurts you

Firstly I have googled it before I put a thread up in here

Secondly - on goggle it does not give a clear info on fitting these to a RB26 there are loads of topics re the RB25

[xashskylinex]

Is the RB25 coil loom same as RB26?

Fitting/mounting the will not be an issue me the main is the wiring/connecting it all up !!

Well

Its not that hard to figure out....

It is that's why I'm asking guys Edited March 20, 2015 by xashskylinex

You cut off the plugs on whatever car you are installing them onto.

You then wire the ls coils to earth, 12v and the trigger from the ecu.

Makes no difference what car .

Yep, what Ben said in a nutshell. Really, there's plenty of info out there on how to do it.

I used this guide to do mine:

EDIT: actually this was the guide I used, but the one above helped fill in some gaps:

http://www.240sxforums.com/forums/rb-tech/137034-rb25det-series-2-ls2-truck-coil-pack-swap.html

Basically for each coil, there is a couple of grounds, a +12v and a trigger wire.

1) I joined the ground from each coil together (in series? dunno what the technical term is) and then had one single ground wire coming out the end of the new harness that then attached to one spot on the valley cover (see attached pic).

2) I did the same with the power wire for each coil, joined them all together. The single power that comes out the end of your harness then connects into the connector at the back of the head with 3 wires going into it (circled green in my pic attached).

3) The other 2 wires in that connector circled in green are i) the signal ground which is also ground to the valley cover, and ii) the trigger wire which you won't need anymore (you will see why when you remove all the back wrapping off the coil pack harness).

When you go about connecting the trigger wires to the wires that go into the ignitor (you will need to cut the harness on the firewall side to do this so you can plug them into your own, new connector), make sure you do each one individually so you don't stuff it up. Good advice here is to take a photo of the ignitor pack as all the wires as the wires are colour coded.

Read the above, then read that link I posted, then read them both a few more times. Once you get your head around it, it's dead easy.

Thank you !!

One last thing thing can you give me the part numbers for the coils

i am just somewhat confused with all the coil packs to choose from which ones to get the rest seems to be easy to do
