i bought a b18 t.b. because i got numerous responses that said that they fit on d series i.m. but u have to port match it. well i went out there just to see if it would line up and it doesnt the bolt holes wont even go through. so please help me out. the t.b.'s off of a 95 ls.

 

nothing fits the HF manifold but the HF throttle body - B-series or 92-up D-series TB won't fit on any 88-91 D-series intake manifold - the only one that fits is the TB from D16A6 or D16A1

The B6 is the HF motor and it's TB flange is different from the D15B7.

I dont know i happen to have a spare 68mm race TB and i bolted it up, im not sayin im right but there is another thread a few days again asking what B parts fit on a D and someone else has done it as well
