   depends how much you have in your budget
   
   if you get a mild cam you wont need a remap and will probs spend around 400-500
   200 of that on the cam, and newmans ph1 is probs the best mild cam, or kent cams pt40 i think it is. and the rest of service bits headgasket and skim etc
   
   if you want a wilder cam like the newmans ph3 cam that needs a remap expect to pay an extra 400 ontop of the above for the remap
   
   plus if you get some one else to fit it will cost extra 300quid maybe? im not sure on costs of camming a vtr these days
   
   so its not cheap mate but well worth it

   thanks, so if i get a newmansph3 cam , i will need a map which i want any way, but wat sort of gasket will i need, i have read some were that if i put 2x 0.4 it lowers compression is this correct, thanks again guys

   dont double up gaskets, you dont want to lose compression. just replace it for the correct gasket, same thickness as the one you removed

   yes as sparco tom says just use a normal replacment gasket but try to get a mls gasket though as they will last longer
   
   to up the compression you would need to get a thinner gasket but doing this you run the risk of the valves hitting the pistons due to the cam having alot of lift
   
   so just stick with a mls replacment gasket, i can get the part number if you want for one? when you need to get one as i work for a motorfactor and got a mls replacement gakset for mine from work alot cheaper that from places like gmc etc lol

   as far as im aware there is no piper 300, only for vts
   
   the highest piper stated is a 285 and for the roller rocker which you have, is actually only a 264deg cam so you would gain less than having a newmans ph3 cam cause that is a 270deg cam, so you may aswell pay less and gain more by geting ph3 mate

    Yeah, most probably as rally engines usually have forged internals. Basically, the cam has a profile which raises the lift by a fair whack, so by using standard internals the valves would hit the pistons, and your engine would become an ornament.
    
    Also for such a wild cam you have probably bought, you would also need some form of iTB's or perhaps a rallye inlet. This goes into quite a lot of £££'s though, well worth it but expensive. You might be best selling the cam on mate and buying a PH3.

    well it wont be piper its more than likely the kent rally cam thats about 300deg
    
    but tbh thats quite a high duration unless your running a hugeee spec
    to gain the most i would say get rid of that get a rallye or xsi head so you can run a ph4 cam and run a decent itb set up you will need forged internals with the ph4 cam as it has very high lift
    
    if you do not want to use forged internals the next best cam would be a catcam 4900645, which again wis for the rallye orf xsi head, alot of people have had very good gains with this cam and decent itb set up, a guy on there has his 8v for sale at the min
    hes made 155bhp from 8v running the catcam 4900645, and gsxr bikebodies with a sandy brown inlet mani set up, also with a 16v bottom end, cause they use slightly pocketed pistons standard which means higher compression
    
    what spec do you currently run on your 'rally' vtr?
