hey guys,
Just wondering if the 20b throttle body would be an improvement on my 93 13b. would it just fit in place of the stock one or would it need modification. would I see any real gains from it? don't know much about interchanging from cosmos to 13bs. thanks a bunch
Jeff

 

ask jspecracer7

 

the 20b people switch the 20b throttle boddy, for an FD throttle body, because the FD one is bigger.... ask me how i know. later -heath

 

Yes it will bolt up. No you don't want to do it unless you do a full Cosmo 13B swap. I tried to make it work, then found that there was very minute changes that wouldn't allow me to use the 20B TB with the FD UIM.

 

That's odd since I measured the 20B TB and it was 2mm bigger than the FD. Did I miss something?

 

i have heard of this , ..its said that the fd`s is bigger
but they looked the same to me , then i heard that the 20b`s is bigger......argh screw it i am sticking with the 20b`s thats all i have anyways

 

thanks guys, theres one for sale on ebay for 10 dollars if anyone is interested. think I'll stick with the throttle body I have.

 

all i know is that many many people running 20b's use the FD TB because the claim "it is bigger"if i get a chance ill measure both of them on the weekend.... im sure there is a reason that the 20b guys ditch their TB's
