But from what I've read here I, need to learn about the insight - I like the idea of not having to work so hard to get sick mileage, and I am a Honda freak so only a Honda will do

in a few months, I'll hopefully have enough cash in hand & ready to buy my own, then I'll have to learn

The secret for mpg in an insight is to shift to sport mode and take on the muscle cars beside you and lift as you approach 5 mph over the posted limit.

I haven't actually checked, but I would bet that there are valve pockets in the tops of the pistons. If there are, then the 8v valves will not be in the pockets of the 16v pistons. The pockets are generally there because they have to be to make room for the valves--so you'll wind up with mashed valves...

A similar problem exists when trying to swap the D15 heads from the DX and CRX HF 1.5 liter engines around: One version is 8v, the other is 16v.

I know nothing about honda engines and just understanding vtec. Seems thats been around for some time too. Thats my mod idea for the insight go to the crz engine. For the sidekick with its 1.6 I like to think about one of the engines mentioned in this thread. Sounds like the vtec and 8 grand redline would be good as it goes 4 grand at 70mph in 5th. Its got rather short gears, so a high reving engine would be nice.
