hi guys! i would just like to ask on how i can identify wheather a throttle body is an authetic j's racing throttle body or spoon throttle body? is there any markings on the throttle? stickers or logo?

the reason im asking is because my friend is telling me he can get me a used one in japan and its original but i want to make sure that im getting the real thing not some custom bored throttle body by a machine shop... thanks!

 

anyone pls? thanks!

 

all they do is take a stock one and bore it out and call it theirs anyway.

 

well I think Spoons is different.

 

oh so no badges on it to tell wheather its spoon or j's racing? thanks!!

 

Check both fore / aft of the inside diameter and measure it. J's Racing TB is wider than Spoon TB at the aft part (J's is about 66mm and will require port matching to the intake manifold). If am not mistaken they do produce also s TB that does not require port matching, but at least is a start to identify it.

Let us know.

 

thanks!! where is the aft part?

 

my spoon doesn't have any badges or stamps.

 

my j's has a sticker or badge on the bottom of the tb. cant see it from the top. but its there if removed.

 

The following is only a sketch, don't take into account the dimensions.

What I meant is the diameter of the far right side just before the intake manifold. Hope is clear now.
