BD5 EJ20R single conversion, coil pack mod tips/advice

[Westy177]

So I'm currently in the process of doing the Single turbo conversion to my RS-B.

I've decided to do the coil pack mod and picked up a complete intake manifold from a period appropriate forester v3/4.

My main point of reference for this entire project has been the thread on dirty'ol BC.

My main confusion with the coil pack mod is the fact that I have a single turbo loom, the write up focuses on if you're using a tt loom.

What wiring should I be expected to do with a single turbo loom?

I have the ignitor and plug.

Also I've never wired before and I don't really want to buy a soldering ion, are there any methods too wire without one? I've never done wiring before.

Soldering iron prob $10 from bunnings. Arent cop better than pack?

Only 10 bucks? right im getting a soldering iron.

I hear their more reliable, plus I have the complete manifold so I'd like to do it.

Fitting the manifold will give you issues with the tps. There are work arounds but they are not really worth the hassle just stick with stock manifold.

Coild pack mod is easy

each coil on plug has 2 wires. 1 sensor wire and 1 power wire.

Join/solder the 2 front cylinder sensor wires together and send them to one sensor wire on the new coil pack

Join/solder the 2 rear cylinder sensor wires together and send them to one sensor wire on the new coil pack

Join/solder the power wires for each coil to the power wire on the coil pack

Secure coil pack in engine bay

make sure to also

Preserve you're current coils wiring setup by going to pickapart and cut some wire and end plugs off some old coil packs.

Grab an end plug for the new coil pack with wires attached to make the easier to join to while you're getting the above

Done. Super easy mod

The throttle position sensor plug? I got that in easy just copied the loom setup.

So I'm getting the wires from the packs that are on the head and soldering the wires into the ignitor?

I'd rather use the single turbo manifold the twin turbo one is alot different.

I'm confused. Which coils are you currently running? the old single bolt style?

I can't comment on tps I don't know why you would swap tps or manfolds tbh as it makes little difference and the gtb has longer runners too. It's quite a lot of hassle.

When you say you're running a single turbo loom... Which single turbo loom? v1-2 or v3-4 v5-6 v7-9 ect?

If you want I could upload a video on how to do it. Would be quick and basic though
