Default 4 – throttle body for Subaru EJ20

Hello! Is it possible to make the 4 – throttle body for Subaru EJ20 – atmosphere (non turbo) engine? VIN GG9-009976
Now I have uniflow discharge 2,5 inch & STi muffler
I know that on turbo engines’ 4-throttle body’s were some times installed, but will it be working on mine Sub?

I find that information

Alex, I think what you're asking about is what we call individual throttle bodies (ITBs). It is possible to do, but not easy, and I think there are very few guys here who have done it. Here are some threads worth looking at:

I suggest you update your profile to show your location, which I'm assuming is somewhere in Europe. People tend to get grumpy when someone posts and their English isn't perfect.

It's going to be pretty expensive, I don't believe there are any aftermarket setups made, unless Jun made one. Your options are pretty much redoing the TGVs to turn them into TBs (not the best way to go). Or have your own custom machined, but that's going to be expensive.
