Does anyone have a list of, or, know the compelte line up of honda TB sizes???

D16 = ?
B16 = ?
B18A = ?
B18C = ?
B18C5 = ?
H22 = ?
H23 = ?

 

B16, B18A are 58mm. I believe the B18C (JDM ITR) and B18C5 are 62mm. The B18C1 (USDM GSR) is 58mm as well (pretty sure). D and H series I have no idea. I think the D's are around 55mm? The H's should be near the same size as the B's.

I don't know about the others but I agree, b18c1 is 58mm and b18c5 is 62mm.

 

i believe the B18b, b18c, newer b16s and H22/3 have 60mm, type r and type s are 62, and old b16 and b18a are around 58-59. Not to sure about Dseries somewhere around 55. These numbers are at the TB plate

h23/22 = 60mm, positive on this

d16 is a 58mm i think?

 

Not one post that was right.

d series 56 except dohc zc/a6 which are 55
b series 90-93 b18a first gen b16 58 mm
all 94+ b series 60 mm also 92-93 b16a
accord 56 mm
prelude 92+ dohc 60 mm
itr 62 mm
s2000 62 mm

Wow working on Hondas and checking specs works. Maybe some of you guys should try it sometime

I thought the H22 Tb was 62mm like the ITR b/c ppl used to use those instead b/c they are cheaper than the ITR!

I may be wrong but I think the H22 is 62mm!

Thats exactly what i though... 92-96 H22A TB's are 62mm, H22A4 97+ TB's are 60mm???

The ITR and 92-96 H22A bore capacity is the same as well...

 

All jdm h22 lude motors I have messed with have had 60 mm. The actual material on the throttle body maybe enough to bore to the same specs has a bored itr tb but there 60 mm stock. Micrometer can come in handy

Micrometers dont lie! Good job!

 

he's right. h series are 60.

only itr (ctr not included) and s2k are 62mm

 

Sorry to jack the thread, but what about the B20 B and Z throttlebodies?
