Hey guys, I own an 07 sportivo..runs fine at any speed (no vibrations) however when going uphill, there seems to be a humming sound which becomes louder and louder. My wheel alignment may be out of place, but wouldn't it humm on flat surfaces as well? Could this be the reason?? And also, since owning this car from September last year, I've had to get it aligned twice already. Is it my driving that constantly gets it out of place or could there potentially be other issues with the axle? maybe.. Should be taking it to a mechanic today to have a look.

Goals..a much better increase in acceleration. By safe I mean...only little change to the internals. I feel as if with too much change comes too much troubles and thus too much money

I understand the camry is only 4 cylinders, but I see libertys which are 4 cylinders and consist of turbo etc. Safest way to increase hp in my camry?
