i'm curious....i have a TB gasket but it doesn't seem to line up properly on my turbo TB but it also doesn't seem that it would cause anything bad. if someone has a pic to compare the two, that would be great


thanks, t3d

If the inside diameter does not restrict air flow from the TB to the manifold, use it.

how many different TB are out there? The one im using on my swap is totally different from the ones that my cousin has it on his car and parts. That and the TPS are different than wat he has. So im just wondering if it was stock on a supra. I saw the same one on ma70.com and the teal supra has that same one.

hah Jdub the reason I ask is because I had a TB gasket from a cheap set that I used after my original BHG repair. It was like two thin pieces of metal with some viton looking stuf between them and on places on the outsides. IIRC it was making a really loud whistling sound when i started it (vac leak). I make a gasket from the one that came of the tb originally and it worked. Since the rebuild I bought a OEM replacement though. I'm pretty sure the one i put on it that didn't work was an N/A gasket.

There is a diference in design, btw.
Just look here N/A:

and here turbo:

Make sure you have the right gasket, and then make sure both surfaces are clean. Put it in and torque down all for bolts. You don't need silicone.

well, according to the TSRM i have the NA TB gasket. but either way one of the holes on the upper intake manifold for the TB is stripped so i have to re-tap that hole. i might as well go to toyota and pick up the Turbo TB gasket while i'm at it. thanks guys for all the help!
