You already mentioned you had a 4" exhaust on your Civic, which I'm sure went along with a similarly up-sized intake and different cams. How did you minimize the negative FE impact of those modifications?

I dont think I come here enough to benifit from a whole thread for me.... Stock pistons can only handle so much so with forged ones at part throttle tuning you can tune very lean similair to the already produced "lean burn" engines.
I did add a better flowing intake manifold and considerably bigger cams... but from variable valve timing which we are all familiar with it doesnt take place until higher in the rpm band where the boost builds but isnt always necessary. Hondas are truley amazing to me and seemed way ahead of their time in terms of technology for multiple applications and longevity
