I did a search, it didnt help.
Just to make sure I want to upgrade my throttle body here soon. I have a z6 with some minor mods. I was wondering what size throttle body to use, and what sizes come stock on
LS GSR Si Typr R and the y8.
I am pretty sure the y8 is the same size
I am also pretty sure the Si and Gsr are the same size but how big?
Type R, Civic and ITR ?

Thanks

Xsi

ITR =62mm
CTR=60mm
GSR=60mm
B16A2= 60mm
B16A1=58mm

I'd recommend the 60mm gsr/b16a2 TB. The z6/y8 are the same size at 56mm.

thanks fellas

WongFeihung

how much do they go for..and how much for installation? what would be the benefit for a bigger tb? better and faster response?

Xsi

I felt much better throttle response going from 58->63mm

Nice listing

Not all of those would fit a D series though, would they? (I know the B series ones will, but what about the f's and h's?)

Spade

Yup they will.

kommon_sense

I don't think that the odb-0 TBs will fit such as the b16a1.

piscorpio

Cool. Just another thought, are there any OBD issues to deal with in any case?

madhatch

Glad I could be your hero (trey)
If you change the sensors to the proper obd I am understanding (not positive) they will work just swell!

TrboInteg

Are there any differances to usdm or jdm spec for the ITR throttle body?

tegboi

what about b17a1's?

Xsi

B17A1 I believe is 58mm.

slowhatch4now

i didnt kno that the h22 throttle body and the gsr throttle body was the same,
ive heard of people putting the h22 one on and porting it, but wouldnt that be the same as porting the stock gsr one ?
