Mot of the GTers use the stock L36 UIM....but..the L26 UIM wont shatter under HIGH boost.......
the L26 is a better option....and with a little modification will fit onto the LIM of a L36.
the blocked off SC housing is what most SC cars do...as it is little to no modification.
if you were to add the LIM from a L36/L26....onto your L67/L32....you would have extra injector ports...as the L67 fuel injectors spray through the heads.....
you would either have to block these ports off....or it would be a good time to add a direct port nitrous kit ontop of it..lol depending on how big you want to go.
