Is this as simple as a bolt on deal? Will the throttle rotor rotate the right direction? How will the sensors match up? Thanks.

 

I did a search, but didn't find an answer.

 

hmm.. the b series bolt on without problems.. but h series.. well i'm gonna guess so.. free dump

 

Can anyone confirm or deny this?

 

it will work but u need to port match the d16y8 intake manifold. use a h22 TB gasket.

 

Yes, if you don't port match the intake manifold you won't see hardly any gains. The bigger throttle body and port matched intake will provide only a small hp gain, the major gain from doing this is the increase in throttle response.

 

I'm not looking for a monster HP gain. I'm going for throttle response. Will an h22 TB from a 97 prelude fit? Are all h22 TBs the same? I know nothing about preludes. Thanks.

 

we just said it will fit, but port match the intake manifold opening to the TB opening, or else its a waste of time. the two diameters are totally off.

 

Thanks.

 

do you have to port match for a b-series throttle body?

Yes. It's the same concept. With just a bigger throttle body it won't do anything because the intake manifold won't be able to flow as well. You must port match.

 

Observe that the map sensor is located on the Y8 TB, make sure that the H22 TB is set up the same way.
