   right made my mind up to save for a vts engine and upgrade it so i can build fir and race down santa pod next year....
   
   what kind of bhp could i be looking at with...
   
   vts engine
   fast road cams
   4.2.1 manifold
   ported polished head
   bmc
   decat exhaust system..
   
   anybody? your all great on here
   
   more suggestions would be good too for example...
   
   would it be worth gas flowing my throttle boddie?
   
   any idea on prices too

   I would hazard a guess at around 155BHP give or take a few horses with the mods you've listed. Depends on the mileage, age how it's been looked after etc will effect it's power output. Some engines will make more power than others even in standard guise. A well serviced engine will perform better than one that isn't regularly maintained.

   If you are going to buy a parted head get a good one. If not forget it. For every good head out there you see dozens of utter shit ones.

   As I said around 155BHP is typical for a VTS with them mods. Standard ecu will be fine for anything upto Newman PH3 cams for example. If you want to go down tb'd route you will need aftermarket ecu.

    i dont think you realise what gas flowing actually means
    
    you do it after you have ported and polished to see how smooth the surfaces are, you wouldnt just gas flow the throttle body with out doing anything else to it
