If I read that right - you want to put the 98 where the 95 was/is?

No problem - straight in, just use the thick head gaskets and it'll be fine. There are extra bolts on the clutch housing of the newer block but as your gearbox doesn't have them they won't be able to be fitted - again no problem.

Good Luck David APi Engines / APi Impreza
