Turbo cam for N/A use only.

Hi,

 

If one were to use a stage two turbo grind camshaft from MSA on a normally aspirated L28 with stock compression, what would be the effect?

Smooth idle?

Great low speed torque/throttle response?

Mid range and top end performance?

Just wondering what a boost in compression might be like from say 8.3 to 9.0:1 or a little more.

Would I have to run premium fuel all the time because of the higher cylinder pressures due to the cam's minimal overlap?

I had a look around in the forums and didn't really find anything that looked specifically into this, but I could be wrong.

I have a heavy car (1978 Nissan Cedric with an L28, 1500kgs, auto, air etc) and would like to keep low to mid range torque and improve the top end power production without actually going to turbocharging. I have another Datsun that will be built with a turbo L28 in it.

What do you guys think? Dumb idea or does it hold some value for my application? From my perspective, bigger cams always seem to rob so much from what I like about stock cams, low speed torque. Can the bigger turbo grind camshaft be an adequate if not optimal compromise?

Give me your thoughts please.

Cheers!!
