TB's and Inlet manifold newage differences
TB's and Inlet manifold newage differences
I have a 53 plate wrx, I believe my throttle body is 60mm diameter. Is there any difference between my throttle body / inlet manifold and that on a same age STI?
Are there any common mods or swaps to the throttle body or intake manifold to increase / improve air flow?

Its the same part, different color.
however swapping over to the TGVless bodies would be a upgrade, but thats not the manifold itself and can be accomplished with the WRX manifold and STI TGV deletes.
very simple mod that takes intake temp down is to insulate the manifold with phenol spacers, separate the coolant tank from the manifold using them also, and removing the throttle body coolant hoses.
Saved me a fair bit of heat in the manifold and thus intake temps.= more possible power

Sounds like good steps to take.
I've seen a 64 and a 70mm throttle body advertised to fit the sti, so either either should fit the wrx ok.
Is the TGV delete for the mani or the throttle body?

TGV's are located between the manifold and the head, where the injectors are inserted.
I personally think the stock throttle body is the best there is up to about 600hp. I wouldn't replace it with a aftermarket unit.
Could as well be that you will need a remap with a bigger TB.
