Default V3 classic to newage coil pack conversion questions

I'm just wondering if anybody has converted a V3/4 single coil pack engine to newage coil packs?

I can pick some up locally and might go for it if it can be done without too much hassle. The loom is available too. I can do all wiring, soldering etc myself so no issues with that aspect.

Is the much benefit from this conversion?

Worthwhile conversion as the classic ones a common for cracking and causing misfire issues and sometimes fail when mapping for decent hp.
Easy enough mod to rule out them problems before the arise and knowing it's going to be reliable in that department.

I'm going to do mine soon.

Mine has a centre coil pack and HT leads going to each plug so I wouldn't have the same trouble as the classic with individual coil packs. That's why I was asking if it was a worthwhile mod for my car. Did your classic have an individual coil pack on each plug as standard?

Hi there, im in need of the wiring diagrams to do this conversion also please, ive got the new age cool packs for my v4 sti but can only find diagrams for the pre face lift conversion that already had coil on leads as standard, also anyone done a Z32 maf conversion on a V4 as can find a wiring diagram for this either. Thanks in advance

Ah I see, I don't know without checking but I belive its got the ignighter box and I plan to rewire directly. It's a 95wrx v2 I think.
I belive it's the actual coil/plug that cause the problems so I'm just doing it as a safety precaution

V1/2 were coil on plug, V3/4/5/6 were spark plug leads. Then back to coil on plug. I'd imagine Subaru went back for a reason.

Corky it's easy to do on yours.

I know Zen do a kit to convert V5/6 cars, and I know of someone who knows how to do the V3/4 - I'd imagine it would be pretty similar. I'm a retard when it comes to electrics, so that's the best help I can offer.

Use Justin's thread, the Yanks are over complicating things.

Thanks but that still only applies to the V1/2 cars. I've looked at the wiring diagrams for V3/4 and it should be easy enough to do. Just means all 4 coils will fire at once.

Sorry mate, I should have quoted Corky, or PM'd him to stop your thread going off on a tangent.

I used to have a PH1.5 coil pack, if I still had it, I'd have pulled it apart to see what was inside. I wouldn't have thought it would be like a distributor cap inside. You shouldn't have all 4 firing at the same time though.

No worries pal! Well as I see it, the ph1.5 coil pack can only fire all 4 plugs at once anyway so it wouldn't make any difference to the car other than there'd be more spark energy with new age coil packs. It's an electronic device so there's no moving parts inside like a distributor would. There's only a power supply, a ground and a trigger cable to the single coil pack. I'll be making the loom so I have all 4 coil packs taking power and trigger signals from the original source.

This thread on Perth WRX has a single coil to COP conversion, all be it V5/6 , it should be the same principle

http://www.perth-wrx.com/vb/mechanic...version-6.html


Hi guys,

OK here goes... Ive got pictures and drawn up a diagram of the loom wiring from the existing plug which used to plug into the single coilpack, to the 4 separate COPs running in a wasted spark configuration. My car is an Australian MY98 WRX and the new COPs are Diamond FK0140's from a Liberty B4 EJ20 Twin Turbo (EJ206 or EJ208) with dwell times of 3ms. The old coilpack that i replaced is a Diamond F-569.

I have attached 5 pictures to this post :

1) COP wiring diagram with all COPs, original connector, and original igniter



2) photo of the modified original igniter (butchered but working) with pin numbers that i have used in the diagram




3) photo of the original plug which connected to the single coilpack




4) photo of the new COPs and the pin numbers ive used




5) photo of the finished loom





The pin numbers i have used in my diagrams are not nessecerily the actual pin numbers and are not a direct reference to the workshop manual, i have just used them to easily show which pins need to connect to what.

Anyways i hope this helps someone - email me on scooby_001@hotmail.com if you've got any questions and ill try return Rossco's favor

Now its time to embark on my next mod.... converting from a 98 stepper IACV (currently separated from the intake manifold) to a 04 stepper IACV (integrated into the throttle body) - if anyone has any pointers let me know

Thanks heaps for your help guys
Rich
