I'm still a newby so i can't open a new thread that's why i'm placing my question in this thread. Hope someone can help me. I've also got an EJ20BUG engine but it's a turbo. The seller told me it came from a gtt from 1997. I took it apart en bought a new gasket set for it and a set of head bolts to. The set was for an EJ20GN impreza/legacy turbo (what the add said) and is the same as the old set but..... the new bolts are 2cm longer then the old ones. And no way they are going to fit my engine. I've been looking and looking (and i'm very bad at finding stuff) but can't find anything about what the length of bolts should be. The seller is also looking but hasn't found anything either till now. The old ones are 18,5 cm from top to bottom and the new ones 20,5 cm. Does anyone know whats going on here and where i could find a list with the length of head bolts....?
