I have a 92 ex accord (f22a6) and am thinking of boring out the throttle and eventually the ITM to match. But I have also been considering just swaping it with another larger throttle body. Somone said use a H22 TB, someone else said use the S2000 TB. Which throttle bodies would bolt straight up and would provide the best gains? Thanks.

 

I bought an H22 TB for mine on Ebay. It works good. I can't remember exactly what I had to do, since it's been a couple years. I think I had to make a new gasket and possibly do some grinding. But yes, an H22 will work, haven't tried an S2000.

 

Any other opinions?

 

Both the F22 and H22 USDM Tbs are 60mm stock.
I can bore either to 64mm and port match the manifold.
The JDM H22 type S is 62mm stock but that TB is rare and expensive.
the S2000 TB will fit as well as the ITR but both are only 62mm and expensive
