Hi all,

I am looking to buy a stock location Blouch 2.5XTR twin scroll turbo for ej207 with 10cm^2 hotside now I wanted to go with a external wastegate setup.

Usually you would need dual EWG for T/S, each for seperate port but I was wondering whether merging the pipes to fit a single EWG would be ok? or would it destroy the purpose of the twinscroll setup?

Cheers

 

2 take offs sort of y'd into 1 pipe would be fine

like so

 

would recomend doing it a lot better than the above though ie lengthwise etc not so long if possible

 

Thank you mate
