Getting a cam ground and head job; Worth it on a Honda?

I own my 2010 honda insight and its got some wear some years and has already tripped 100k miles. The car lacks like 15 hp and its 1.3l engine is rated at 88 hp and 88 tq at 4700 rpms 10.8 compression 8 valve SOHC. Ive been told getting an eco or torque grind on the cam will make a big difference as well as the usual port, polish and milling the head for a bump in cr. Ive had others tell me Honda knows valves, cams and stuff and I or anyone else can improvement upon it. :ermm:

Its torque peaks at 4700 rpms, cruses at 1800 rpm at 60 mph, has like a 5700 redline. For the most part it feels gutless and its hard to tell where the power band is. Id like to get what I can rather its up high or down low, but Id prefer down low as the cvt makes use of the entire rpm range.

So, is this something I should consider or just go with a methanol water injection or something else? I can see a bit more drivability with 93 octane, so I am sure a bump in cr would help if anything.

Thanks.

Well, I'd say mainly your problem is it's a cvt. That's like 75% efficient compared to a 5 speed. Nevermind that however; nothing you can do about it. But yeah, since a cvt likes to find the most powerful spot in the rpm range and constantly run at that rpm, theoretically a torque grind would lower the band's power in the rpm range and give you a lower cruising rpm and better power right off the line. That being said, when's the last time it got a real nice tune-up? I found that the most important thing on my vehicles were the plug wires. Also, I really wouldn't bump the CR up any more. Technically the lower the octane, the more power you're granted. I'd think you'd get more bang for the buck at 87 than 93, but you're the driver; I've never driven your car. Also, maybe honing the injectors might help? Have you done a compression test? Personally I'd stay away from doing extra such as the CR or meth/H2O injection and just fix what yah got.

Do you have manual shifting capability? If you do, you can also manually shift at peak torque (if the CVT is programmed on a different, "less than peak torque" schedule). Your torque and power may be lower than they were originally, but shifting at peak torque would get you the most you can get in its' current condition, whcih may be more than allowing the CVT to choose the shift points. :dunno
