   It would be stall city I would assume. I doubt the stock ECU would be able to deal with the required adjustments to the fuelling for one...

   it's pretty lairy that cam.
   
   Think it's a close call with the valves and pistons as well.

   yer the ph4 is for the rallye and xsi heads
   
   and from what ive read they have bigger bearings so the cam cant be used on the vtr, i maybe wrong onthis though, its just what ive read

   ph5 is for race use, so yes i would imagine so.
   
   Ph4 would need headwork, standalone, and throttle bodies.
   
   You'd see very good gains though.

   Best bet is to go for ph3's unless you have deep pockets.
