   Hi i want to ask i saw a tu5jp4 from a xsara today and i think if i take the head and put it on my saxo vts would i get a power gain because jp4 has biger valves?

   From what I know the jp4 has a 110bhp in comparison to the 118/120bhp the j4 unit has.the jp4s has 120+ bhp I believe.
   
   What you have to do is fit the jp4 head and then fit j4 internals to give a good power gain.
   
   
   Same idea as this

   But instead of fitting the 705 cams you can fit the std cams from the j4 head.

   And is it hard to fit a jp4 head or it is just unbolting and bolting the new head

   I think its best to put the cams springs and everything from the vts on to your head. Because the jp4 head has bigger valves.
