I heard somewhere that a h22 throttlebody will fit a sohc manifold,does anyone know if this is true and if so what year??

 

You can make it fit....?

 

if thats true then you can fit a s2k TB

I have a H23 sitting at the house and a B18b1 IM...ill try to line them up since the 23 and 22 use the same TB

 

I had used a GSR throttle body on my Y8 swap?!?!

 

so B18c1 TB works on a D16y8 IM?

 

Yup.

 

so if I can proove that a H23 TB works on a B18 IM, that then means a s2k TB will work on a D16 IM....wow Honda you may have done it again

 

they all fit. the difference is in the bore size. all the TB's have the same bolt pattern/tps/map sensor. i don't think an s2k TB will work because i've never heard of anyone doing it. but i know that the H22/B series/D series TB's are all interchangeable. however, if you upgrade to a bigger TB and do not match the bore of the IM to the bore on the TB...you will probably not see a damn difference in performance.

 

Hondaaaaaaaaa baby

 

Mike:

Preludes can attach the S2k TB to the stock manifold, we only have to rerun the coolant lines to make it work...kinda like using the Euro R H22/H23 TB on a USDM IM
