throttlebody questions with pics......

[SpeedRicer]

maybe i thought wrong but i thought all b-series TBs should bolt on to d-series IMs. i got a TB off of ebay and i am uder the impression that it is an 91 integra TB can somebody look at it and tell whether or not i got what i paid for and why it's not bolting up?

i think it wont bolt up cause its a d15z1 or hf manifold... go get a d15b7 or d16z6 manifold

z6 mani ftw add a 94+ integra TB... i bought a y8 mani then reasearched and the z6 seems to be the better choice. i'm sending to maxxbore to be matched at 64 mm a little costly but worth it imo :noway:

if he gets that manifold, the throttle body still wont fit.

get a z6 manifold and a b16tb. bore manifold inlet to 60mm and you're golden, chief.

ok so i need a new IM and T. there's no IM i can use with the TB i got? and the z6 should bolt right up, correct?

[Black91CRXsi]

To use a B series TB(which you bought), you need a 92'+ D-series IM... Either from a D15B7, D16Z6, D16Y8, or JDM D15B... 91' and older D-series IM's have a different bolt pattern than B series IM's.

God deal so everything should be just fine now:TU:

... btw that old manifold you had will not perform. id be surprised if you could fit 2 fingers in the ports.

you should get a picture of the 2 manifolds next to each other, and u will see what we are talking about.

[SpeedRicer]

Honda/Acura Throttle Body Inside Diameters (in mm)

B18C1 60
B18C5 62
B18A 58
B18B 60
B16A SiR 58
B16A SiR2 / B16A2/ B16A3 /B16B 60
B17A1 60
B20B/Z 60
F20C 62

D15B7 56
D16A6 55
D16Y7 56
D16Y8 56
D16Z6 56
D16A1 55
D16A8 55
ZC 55
D15Z1 (different bolt pattern) 40

H22A / H23A 60
F22/ F23 60


Note: Most Honda Throttle Bodies are tapered and the outside diameter is larger than the inside diameter.

ITR/S2K/RSX-S are 62mm



so in the end... you should just find a d16z6 intake manifold cause the one you have is too restrictive, if you have a b18b tb its the same diameter as the sir... unless you have a b18a which is 2mm less...
