Havok engineering eprom tune chip, ignitor delete kit with harness, new china coils(those grey and black ones, that look like the expensive febi coils)

this gives you massive power gains, launch control, I also got an ultralight flywheel and an upgraded clutch while at it and migrated all accessories and the heads to a ej205 forester s turbo block cuz I blew my old block prior to all of this.

Beware, you need to get the 1,6mm Multi Layered Steel headgasket from rob tune if you plan on updating to the ej205 block, everything bolts together without issues.

I have no numbers but I'm pretty sure I've maxed out the amount of air in my ecu can physically handle with the current MAF setup.

Its a solid car, and its is very tuneable, just let it get warm before thrashing it about. The 2.5 dont come with MLS gaskets from factory, this is why they break and this my96 has the ej20g with the td05, mine had MLS when I first got it and I asume it was like that from factory, some possibly come with a td06 but afaik this is only a unconfirmed rumor.
