will a bseries throttle body fit onto a oem h22a1 intake manifold???

 

I'm not sure if it could, but even if it could, it would just cause power loss I would assume.

 

I was going to make an assumption post as well, but since I didnt know for sure I didnt bother posting.

Inlet size may be smaller on a B than a H, bolt pattern also might be a factor. Not to mention not sure of the location of the IACV on the B's. So....Generic post.

If you had them side by side you could measure for sure.

 

Inlet size must be different, H22's have to have the more airflow for the engine for it's needs due to obvious reasons, so I'm going to say it won't.

 

Is the TB in question OEM or Aftermarket?

 

Yes, it fits on an H intake manifold, I had to use one in a pinch.

Like said, they do fit, unsure of the size difference though.

 

H22 is 60-65mm depending on where you look, most B-series are 55-60mm. You won't have a fitment issue, but you might have a slight loss of performance depending on the particular TB you use.

If you were to go the other way H-series on to B-series, you could have a fitment issue, where the TB wouldn't open cause it hits the IM.

 

I'm surprised stock fits, knew there would be power loss, slight or not. Suppose a running car is better than nothing.

 

I used one to get my car running, at that point, performance wasn't my concern. It's not like I dyno tuned that way, so I couldn't give any true numbers or anything on what you lose, but it can't be too much, especially if you use a GSR TB which should be very close to the size of the H-series TB

 

True, I would rather have running car than none, the performance difference is probably only off at most 5-8hp which isn't anything significant unless you're going for an on the second car.
