Hey,

I've searched and haven't been able to find any info on this. I was able to find the info for all the other B-Series, except the B20. Does anyone know what the Inner Diameter for the B20 Throttle Body is? I need to know this info ASAP if possible. Thanks!

This was the info I found on the other B-Series Throttle Bodies (if its incorrect, please point it out as well).

B18A: 58mm
B18B: 60mm
B18C: 60mm
B18C5: 62mm
B16: 58-60mm (Depends on Year)
B20: ??????

I would appreciate any help greatly, thanks in advanced guys!

Anybody know?

 

Alright, well I did some more in-depth search and apparently the B20 Throttle Body is 60mm ...

I am going to be running this B20 Throttle Body on a AEBS (65mm) Intake Manifold. My question is, will I be okay? I will later (when I get some extra money) get the Throttle Body bored out to 65mm. However, in the mean time I want to know if running the 60mm TB on the 65mm AEBS IM is fine.

I plan on using http://www.maxbore.com to get my TB Bored to 65mm, any used them before?
