how big is it and what can you bore it too. and yes I did search and found nothing. I found one post that said maybe it was 60mm tho also how big is the gsr tb

 

i think they are 62 or 64. i think the biggest you can have it bored to it like 68. just buy a nice spoon 70MM

 

how are the gains of borring the stock one out ?

 

its almost not worth boring the stock one. you can get a nice used 70MM for around 200 i think. 68 MM is pretty big for a stock one, and you have to have a new butterfly valve made. some guy on here does them for like 100 bucks.

 

so is it 62 or 64

 

its 62

 

spoon makes tb's for our h22's 70 mm??
sounds nice!

 

whats the dif of the spoon one and a bored out stock? cant the stock not go up to 70mms or something?

 

it's spoon

 

you can only bore a stock one to 68MM. After that is just weak sauce

 

Auto = 58mm
Stock = 60mm
Type-S/Euro-R = 62mm
Max Bore = 64-64.5mm

you can't bore a stock tb to 68mm

 

68 is big...but spo0n 70mm sounds sick n-e-before and after pics of a bored out stock vs. stock?

 

never said i was the TB master. i was just sayin. i recall 68MM as a good # but 64 works too. whatever. If you are thinking about doing anything TB get a new big one end of story.

thats taken from the guy who does over boring of TB's on here. so we both wrong.

I've never seen 66 on an H22a TB, so I'll stick by comment.

 

anyways, bigger the better? spoon is the way to go ?

no...if you don't have supporting engine modifications to support it I don't see the reason to get one.

i agree, the best way to benefit from a larger tb is to have other work
done like ported head and im, cams etc. otherwise it's a waste of money, imo.
