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

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

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.

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

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
