Throttle body gasket

[LoveMySupra]

I have found 3 different throttle body gaskets for the 7m.
One that is available at parts stores for the turbo engine has a little opening. I'm going off memory but i'd say the opening is about 1.5" in diameter. When put against the throttle body (off the car) and moving the butterfly the butterfly will touch the gasket. Btw, this gasket was $2.
Doing a google search I found two other gaskets. They both have openings that match the diameter of the butterfly. One is for a n/a engine and the other is for a 89+ turbo engine. One of them has mickey mouse-ish ears that contour the top of the throttle body to accomodate the vacuum line ports up top and one doesn't. The one with the mickey mouse ears lists around $15 and the other lists like $3.

What are the differences between the 3 :Q:
Why would one obstruct the butterfly's movement :Q:
Should i cut the one i got to match the full opening of the butterfly.. Should I also cut out the mickey mouse ears :Q:

thanks in advance,
will add pics this late afternoon..

That's why I bought mine from the dealer. Also one of the reasons I think felpro is a ripoff as their gaskets look exactly like the super cheap stuff you can get on ebay...

I've learned the only intake kit the parts store has is for the N/A supra. That little TB gasket u got is the same one they gave me at Oreillys when I tried to buy a turbo intake kit. Anyways what I ended up doing is buying a sheet of Mr. Gasket intake gasket and creating my own gaskets for the TB, ISC, and CSI

Oreilleys can order the other two.
I'm going to cut the one i got to fit the inside diameter.
Why does this crazy one exist with a waayyyy smaller diameter opening..

yeah ive always used the one you can get from the part stores and just use a razor blade to make the opening bigger

^ Beer first. A TB gasket change is a two beer job

Old mechanic's trick: place gasket material on part and tap lightly around sheet with ball peen or screwdriver handle to imprint. Tear/cut as needed. Crude, but effective...

10$ from champion or elmhurst toyota on sf. It can also be reused.

or I sell re-usable gaskets made from teflon for 30$, it'll be the las one you'll ever buy.
but more realisticaly go with what hvyman said.
