   as above tbh, got a ph3 in the vtr atm and its covered next to no miles, do i keep it or sell it and go for a turbo spec cam as i was originally planned, seems daft to just sell it on and it would save me time and money if i keep it?
   plan on running just over 1 bar boost???
   opinions much appreciated

   Have you compared the cam specs? There is no real reason you can use a mild normally aspirated cam. As to how good it will be it all depends on what your after.

   turbo spec cam will obviousley be better but the ph3/285/708 type cam is supposed to repsond well to a small amount of boost, having not looked into using n/a spec cam i dont really know how well itl work, was hoping that someone whos ran 285's will be able to put some input in on how well itl go??? just thinking of it being virtually brand new is there really anyone point selling it on and forking over more for a custom catcam?????

   For most turbo applications we have found that the standard cams/cam works best. Turbo cams seem to make little or no difference. Go for standard on turbo.

   how much do you think you could sell it for, you can get turbo spec cams for less than £150

   wanting 150 for it mate its done less then 1k, more realistically about 4-600miles, cheers ian but i no longer have standard so its either turbo spec or my ph3, was looking at the cituning re-profiled cams bt theyve got no spec's? and far as ive seen no one on heres used one(so im a bit sceptical), 145 on exchange iirc?

   My only view is that on a 16v it's relatively easy to switch cams over if need be, whereas with an 8v it's a bit more involved.
   
   People seem to go for a milder exhaust cam on a 16v so this allows you to reduce overlap whist still keeping the na inlet cam.
   
   I'm planning on running my Piper BP285s with boost, and Andy-l is running 708's in his supercharged 16v with 300@wheels.
   
   I'd opt for a turbo spec cam, and sell the ph3. If the ph3 does have too much overlap, then will cost you more to simply change the hg, than it would be to switch to a turbo spec cam now. That's what I'd personally do, but purely because you don't have the flexibility to vary the timing of inlet and exhaust cams independently, and change them to milder cams to - effectively running an inlet and exhaust can that suits the car best.

   this was my main concern in the firts place tbh ross, its alot easier on a 16v and in all fairness id dont really wanna have to have the head of if i find im getting a fair bit of overlap once its up and runnning, i know you can get good gains from this type of profile but to what boost rating on a vtr??? know one really knows, gonna be more worthwhile to go with the turbo first off isnt it?

    I would say so - it'll give you the best chance of gains fitting a cam I'd say!
    
    But then engine builds would be nowhere without people trying things out to see if it works or not - and going from there........

    Wanting £10 collected matey. It only did 32k miles from new... taken from a 52 reg VTR.
    
    Ideal for re-profiling, or it might even have a different profile to the 90bhp VTR standard cam?
