The ignition coil pack, not enough space between that and the intercooler for it to slot in. Turbosmart Dual Port looks shorter but the Car Mods Australia bloke reckoned that wouldn't fit either.
Apparently this is a bit of a known issue for JDM Foresters and GFB fitment. 🤷♂️
I'll be investigating the Turbosmart Kompact Dual Port tomorrow, found them on the Repco website so if I'm really lucky there might even be one in stock down the street I can try for size.
Yeah, the GFB Respons, sadly not enough clearance. I'm gonna need something with a lower profile, the GFB is exceptionally chonky!
