im about to send out a LS t.b to get bored out, are the gsr/ itr stock ones bigger to begin with and if so how much, and will obd 1 94-95 LS and GSR t.b's be interchangable on say a skunk manifold thanks

 

 

the gsr and ls are the same i belive....and the itr is bigger...62mm?

 

bump

 

b18b and b18c1 are 60mm
b18c5, b16b are 62mm
i think prelude is 60mm as well

 

Are you sure that the LS is 60mm?? I thought that they were 58mm lik the B16A.

 

b18c1 = 60, 62
b18b = 58, 62
b16 = 58, 62
b18c5 = 62, 66

b18c1 and b16a are both 60 mm. ls is 58mm. the type rs however are 62 mm.

 

anyone know what sizes come with on the b18a1? and the b17a1?

 

i know b16a are 58mm and not 60

 

b16a1 and b16a3 are 58mm, but a b16a2 is 60mm

 

second gen b16 is 60mm.

 

it tapers from 62 to 60.

 

whats the best size aftermarket Throttle Body , and whats a good brand to go with, that would be best for an all motor 99 ls wit small amounts of nitrous, like a 50 shot... thanks

 

paying over 500 for TB us gay send it tp maxbore for 100
