Anybody know if the B16A2 and B18C (Type R one) have the same throttle body gasket?

IIRC the 62mm tb comes on the B18C GSR spec. but its got the gay reveres pull, which can easily be fixed by swapping a regular pull from another honda TB.

there might be a 62mm on a JDM GSR engine, but i doubt it. based off hondas use of the 60mm TB, pretty sure they only went out of there way for a bigger one on the type-r.

on this list, only 62mm stock ones were on the type-r and the s2k. though, it might be wrong.

I was always under the impression that the B18C-R was the only engine with a 62mm throttle body, but I'm an impressionable biff, so I may well be incorrect.
Think I shall order a B16 TB gasket and see if that fits as I can't find the part number for a B18C-R one.

Damn typing is hard when you're wasted!
