i have an intake manifold from a jdm b16a engine ... its just a bare manifold. and i was wondering if a gsr tb is any better than a si tb ?? like i know an itr one is really good ... but i dont wanna dish out the money for it. also what sensors come on a throttle body .. just map sensor and throttle position sensor right ??

 

the gsr tb has the butterfly lever thing facing the opposite way as, i believe, all other b-series tbs........... even if it is better, which i doubt, i'd still go with any other one.........

 

B18c and b16a throttlebodies are the same size
gsr tb has a reversed throttle pulley meant for gsr intake manifold so
since you are using the b16a manifold you would want a b16a or itr tb

 

hmm thats what i figured. thanx thou for the help

 

You can use a GS-R TB with a b16 manifold as long as you switch the TB Pulley and spring, so it goes the other way.
