what parts of the usdm engines CANT be used on the jdm motor? what has to be jdm parts?

 

im not 100% sure but this one guy posted something about this the other day, read the prelude archives on this one or do a search. it was discussed probably 3 or 4 days ago. good luck

 

sorry, i gotta bring this up to the top

I just ran a search (actually about 20) and every post had a link to a article on hondaprelude.com which is now gone. So can someone point us to a new article? or list what is needed for the h23 to h22 swap...

from what i know all you REALLY need is: the H22 long block and the ecu

then just swap engines and run vtec wires...

but some confirmation would be nice.

thanks
