I have a TB thats off a b16a..
i just measured it and its approximately 58mm
now i've been told that the b16a is 60mm and the ITR is 62mm
what size is the b18a/b TB's?
and if this is truely a b16a TB why is it 58mm?

thanks in advance

 

ALL b and h series engines are 58mm at the plate and 62mm at the neck.
ITR and Prelude Type-S are 62mm at the plate and 66mm at the neck.

 

the jdm sir2's use a 60mm
but us b16 and 1st gen jdm are 58mm

 

thanks for the replies,
i'm boring this one out to 62mm
i spent an hour in the machine shop today trying to figure out what's the best way to do it.
i've decided to put it on the verticle end mill with a boring bar.

trying to chuck this up in a lathe and use a dial indacator to get it set perfect is just too much work.

 

Let us know how your t-body comes out for your 93integraRS.

 

heh definately..
i work for the engineering department so i'm gonna get them to order a new boring head for the end mill.. i could go down to the technology building, but, i'd have to wait till their end mill was free.

 

i hear of people using FORD TBs, if i ever know which one, i will try it myself.

 

hmm.. well that would mean they'd have to be the same bolt pattern .. interesting
