I have my v6 throttle body, and everywhere that I find a tutorial they say you need to get extended hoses. My question is what ones need to be extended and what hoses can I use to extend them?
Thanks for any help the pictures attached show what I got

on your picture on the left. you have to extend the hoses that are coming out to the left and the one on top
It blows my mind how nobody looks at the manifold flange and sees that putting a larger throttle body on it nets you literally nothing. The flange is 55mm, putting a 60mm tb in front of that is not going to net you even a tiny bit of performance.
^as long as the throttle body plate doesn't hit the flange on the intake, you're getting an added benefit.
Not at all. The air is still bottlenecked by the 55mm opening in the flange and anything that hits the flange is deflected backward. I've done the swap on a few cars in spite of the obvious idiocy associated with it and it yielded not a single horsepower.
Even without porting his intake manifold he should see a pretty significant increase in throttle response though right? I understand the unported IM is bottlenecking peak power, but at any given throttle position (within the limit of the IM restriction) the larger butterfly is allowing more airflow, which should translate to snappier throttle response...
i agree with Silvertune. you have to open your intake manifold, that risk it snapping off even more, plus the engine can only draw so much being NA, its too much hassle not going to see gains from 5mm increase

I'll also agree with both parties.
My experience with this was with my 4g15:
Initial take off is sluggish at best but to the foot felt held back. With an upgraded throttle body that sluggish from stop to go vanished. It wasn't like adding some kinda big power booster and while cruising speeds you wouldn't be able to tell the difference.
But to get the full benefit I'll have to give it to silver tune. Port matching the intake manifold is the only way to go to actually have all the benefits of the larger throttle body. It's easily done by putting the larger tb's gasket on and coloring in the metal showing within the hole of the gasket with say a black marker. Using a tool like a drimmle will grind out that part you colored in and also a little bit further in will be all you need to port match and have proper air flow without that "damming effect".
Caution: larger tb is a +. Over porting the intake manifold is not and will make the structure weaker.
I I've been driving this galant now for a month and I'm very impressed with the 4g64, but it does have that first stop to go hesitation this tb swap well cure. I'm sure this is why so many love this swap.
