I was considering sending my LS throttle body out to have it bored by one of the board sponsors, but i was having a recent convo with someone who told me when you bore out LS t/b's they become very thin and can snap. Has anyone ever heard of this? How big would they have to bore it to be easy to snap? i dont want it huge, just like a 60-62mm....

 

it depends how much yoou bore it bro .

 

dude..i just had my jdm b16 tb sent to him and bored to itr specs...and its great. You cant beat that deal....yes it looks thin but when you get it back you'll be able to tell that its not so thin that it will break...Plus turn around time was great...i sent it out and got it back in less than a week....You'll be very impressed i assure you.

 

isnt stock bore 60mm?

 

what are the gains of doing this bore?

 

who are you guys talking about in terms of sending it off to? I can't find the site sponsered peps like.

vnt

 

the sponsor is maxbore.com

they do great work and have a nice turn around time

 

On a B18A t/b the stock bore is 58mm, so the most you could bore it to would be 62mm. I would just buy a stock b16 t/b and have them bore it to 64mm since the stock bore is 60mm.

 

Good info, thanks

 

try a s2000 throttle body...i just bolted one on with no modification needed...works good....only thing is...theres no idle screw on it...but it stills idle koo...i think its 62mm...someone correct me if im wrong...

Well just to inform you also that even a b16a1 t/b is factory 58mm. therefore can only be bored to 62mm. so if you plan on going to 64mm size then you'll need a b16a2, gs-r which will bore to 64.5mm, and a itr which will bore to 68mm. All are completely safe bored sizes and i'm speaking as a very satisfied customer.

i think he meant 64.5mm...he probably had cylinder bore in his head

 

haha you guys caught me slippin, my bad i was meaning 64.5mm. late night posting owns meh.

 

so you doods with bored out throttle body's..notice any difference in performance?

 

more throttle respons for sure, but it also helps if you have a port matched intake manifold, and a plenum that's the same size as your t/b.

 

whats the skunk2 manifold plenum size?

 

64mm, just like the stock ITR plenum. hence why the ITR has more throttle responce than all other hondas, let alone the port matched t/b-intakem mani-head-exhaust mani. hence why they make the power they do.
