Steeve - you say : "I suggest you stick with 260 cams or possibly go with 264 HKS solid compatible camshafts for even more mid-range. "

Why would 264 give me mor mid range, and 270's wont ?

Also, i dont really understand - what is the theory about using smaller/bigger pleanums and low end torque on a turbo engine ?

About the Cams - if everything shifts up 500RPM, but i still make power, up top, then it wont be so bad i guess - providing i can rev 500RPM higher, then i do today.

Anyway, any dyno numbers, on the torque/power difrence, of 260 and 270 cams, on the same engine/turbo etc. ???
