Ok I tried searching for this already but I only saw sizes for others. I know this is very basic but does anybody know the throttle body size for the B18C1?

 

58mm

 

58mm really I thought for some reason it would be at least 60mm.

 

58mm
way too many people think its 60mm

 

he's right 60mm

 

B18c tb is 60mm just like a b16a2

 

The DC2 GSR TB is approximately 62 mm at the inlet and 60 mm at the throttle plate.

this might be a dumb question, but would a b16a2 throttle body work on a b18c1?

 

60mm

It will bolt up fine but you will have to alter the vacuum and coolant lines
