Default any way to get these here?

the diamond coils for the early ej20g motors? i saw where someone on ebay was selling some SVX coils and all 6 looked JUST LIKE the jdm ej20g coils.

just wondering if there is a compatable USA car with them where you could go to your local auto store and order them.

otherwise im just going to do the conversion if i can ever find some broken jdm coils so i can cut the pigtails off.

It depends on which engine you own. The Legacy Ej20G engines use a coil that's nearly identical to the SVX coils. The WRX Ej20G coils are slightly differently shaped and use one instead of two bolts. However, in a pinch you can grind some off the SVX coil and make it work. The plugs are the same.

However if you go to your local store and try to order them, you will find that they are practically just as expensive as new WRX coils are, at which point you start to question cost effectiveness depending on how many coils you need at that point in time.

I have a complete sets of 4 WRX and 4 Legacy coils with no cracks in their tips that I will sell. I usually sell them for $80 shipped in the lower 48. I might have a few singles too. I don't actively advertise them anywhere and only mention it from time to time when someone starts talking about needing them. So, just put that away in the back of your mind if you ever get in a pinch.

The biggest difference, like Matt said, was that the 20g coils use 1 bolt vs two.
If you can't get replacements for cheap, it's just better off doing the conversion. It's real easy anyhow.

I know I at least have 6 broken ej20g coils and a few working ones. That is another option. 4 of them are missing pigtails though. heh I'm just like Matt on that as well.

Pretty sure the SVX uses the WRX style single bolt coils. But like Matt said, I believe the profile is different.

Ah proof! I guess it's the legacy that has the 2 bolt style?
Take a pic of the svx coil when you get it!

The SVX coils will fit into WRX EJ20G and EJ25D heads perfectly. Personally tested. This also means that SVX coils should fit EJ20K, EJ20H and EJ20R heads just fine.

Legacy EJ20G coils have a smaller diameter on the 'mounting pins'. This means that to mount them on any other engine you would need to drill out the holes to use the larger mounting bolt. This would leave the mounts very thin, but may, or may not, pose a problem.

To use SVX or WRX coils on the Legacy EJ20G heads you would need to find a way to reduce the diameter of the 'mounting pin', or drill out the hole in the valve cover to match the larger size.

I wonder why there is a protrusion on SVX coils anyways?
