I purchased a ITR intake manifold and a throttle body.

and I don't have a mesuring tool.
the intake has a P73 stamp at the back.

but the TB was definatly reatached to the intake, and the grease marks weren't the same(didn't match up)


so HOW can I tell by looking at it, if it's a B16 or B18c5 Tb ??

and is there a cosmetic diffrence between the 96-97 and 98-01 tb ??

thanks

 

Most ITR Tbs if not all have a stamp on the TB that reads "GF89A"
