Ok, need some help here, hoping someone can help out (@GeneralDisorder?)
First GT forester series 2 (2002) head is off. Piston is noticeably different - GT on the left, EJ20G/whatever it is on the right. This EJ20G/x piston is what came with the heads I’ll be running with.
I’m now worried the valves might hit the pistons. I’m hoping I can put one head on (not fully torqued down and thinking without the gasket too), refit the timing gear and rotate the engine to find out if the valves will kiss the piston. Also to note, the GT had thin MLS head gaskets, the HG units I got ages ago in prep for this build are thicker composite gaskets (OEM).
I really don’t want to swap pistons on this thing!
Here’s hoping!
Some background info on the build: this will be going into my Gen1 RS turbo. The heads match the intake bolt pattern and the intake equipment matches the engine management system, hence the head swap onto a known good block.
And no, I don’t want to run later model management or run aftermarket management, please leave comments like that to yourself thanks!
Cheers
Bennie
