I thought they were toast after the head gasket issue. Does the head gasket replacement work? I should do more research.Grab a D2 that's had the head gaskets done.
That's the biggest issue. Coil packs are a bit of a pain since they're mounted on the back of the motor with almost no clearance against the firewall. Other than that, they eat cooling system parts, but they can be had fairly cheap and are easy to replace.
