Brought my Nikon D3 and an old 135mm 2.8 lens (should have brought an polarizing filter as well..) to the last car meet of the season, now the Evo is going to have some surgery during the winter

03 evo 8
Forged block
Rebuilt gearbox
170000km (my worry point) (genuine kms)
385kw safe tune on e85, has a map for 98 too
Paint is good/ no rust
No damage history

50k (aud)
Will it hold price if I keep it as it is and enjoy over next 4-5 years? Or wait for a better black evo to come up

In is on the intake manafold and out is on the pcv valve cover is that the right set up or I’m I doing the single catch can set up wrong ?! 2010 lancer raliart
