Re: 87 8v throttle body!

["Ryan Schuermann" <rts@nol.net>]

umm heres how to tell, on the manifold, is the stock hole as big as 
the orig one or is it as big as the neuspeed one? take the s-pipe off 
and manually open but venturis (full throttle) can you see any of the
manifold through the venturis? it would be noticable. if the NS 
measures bigger than yes you had the smallone, look at my website, i 
think under the silver scirocco, maybe the cabriolet i have pictures 
of a ported manifold and the difference between the audi manifold and 
the stock 1987 JH cabriolet t-body (which was the small one)

people
