I was doing some reading on this same subject. Johann (who seems to have some chops with these cars) suggested in an older post to only use the NA intake cam.

I figured his suggestion was from a reliable source.

By just using the intake n/a cam does that provide a more even power spread?

kind of, can make adjustments to the powerband. Advance for more low-end or retard for more high end.

I'd also like to do this in the near future, to those who did both how big of an issue was overlap and what would you say your actual adjustment was?

What is the range of the low end power band? Does that mean that you entirely loose your high end power, or it's just turned down a bit?

It seems like there's a lot of unknowns with the NA cams.

No, All it simply does is shift the power band slightly...

It is known to the community that about 15hp is gained from switching to NA Cams (Yet its hard to find exactly what setup, intake only both or exhaust)

Advancing and Retarding Cam timing makes a huge difference in the powerband though! So be careful how much you advance/retard

and considering you can find a set of N/A for about 20$ a set at a local junkyard thats almost 1$ per HP, if only everything was that cheap!

I set the cams at the stock turbo settings, which is about 4º adv EXH 0º INT

there was a lot of info on the QBM website about cams. its all gone now :(

I downloaded the PDF. I can always email it. I have no way of web-hosting PDF files. Same goes for the Mitsubishi Turbo Rebuild Guide - great reference for anyone doing it for the first time.

If you could email it to me, that would be great. My email's in my profile.
