You know how everyone is fixing up their cars to to be weekend warriors and what not? Well I drive a stock HF, and i was wondering if it would be worth rebuilding an HF engine to achieve maximum fuel efficiency.

Now hear me out. Gas is hella expensive and while most people put thousands of dollars in their cars, with good performance results, the oil tycoons make you pull out a home equity loan just to keep your wheels on the road.

MPG Happiness.
Now, i have been getting about 44-48 mpg with my Betsie, so i guess i shouldn't complain, except for the fact that i have a slightly smaller tank than the rest of you so every 300 miles or so, i have to refuel (have to drive around alot). I really feel that i can get more out of this car, especially since the Insight has a i3 engine (but with vtec) and electronic assist that gives it about 90 hp, versus my 62hp. (correct me if i am wrong). And yes i know that the Insight has an aluminum body but, it is just a benchmark for what i would like to have.

Reliability.
Also, i know that everything in the HF engine is puny so i would like to have a better piece of mind knowing that my weak, puny parts are reinforced (connecting rods and all that sort).I'm pushing 163k on the chassis, and engine and stuff is starting to die finally(right now the alternator). Everything besides the battery on this car was stock except for the normal tune up stuff and wheels (plugs wires battery etc, brakes). So far i have replaced the Starter motor (which later found out was fine), ignition switch, struts for the hatch, and intake (i have a CAI). Soon i will do a rear disc conversion.

Performance.
Most of you who are concerned with performance and power, tell me if you think this is a good idea? I mentioned an article in import tuner or Honda tuner mag (can't find the mag right now) about 2 years ago where they installed a garret turbo from a stock eclipse to push the '90 HF to about 160HP with about 6 or 7 psi. They did this reliably and actually were able to push the stock rex up to about 200hp with about 192 or 196 ft-lb of toque, but because of drive ability and fear of breaking something, the dropped the psi to about 6 or 7. So if your concern is about performance, then this could be an option with alil bit of fab work. But notice how i said option.

or...

Another "Bad Idea".
If you guys think that this is a bad idea (just like my CRX with a Rotary engine idea), How about a diesel CRX. Now i bring this one up because i am a fan of diesel engines and Honda has recently make a diesel CR-V in the land of 'pan; i bring this up because i have heard of people doing CR-vtec swaps (i know nothing about these particular swaps)!? Was just wondering if this would work, because i have yet to see a diesel crx. I know it would be a heavier engine (its diesel) but it would most likely take better to turbo or supercharging because of the nature of such engines. This little section is in fact for the weekend warrior rex.

In conclusion.
These are just my thoughts. i would like to see what people think, or if you have any suggestions on the topic. An please no smart ass remarks, I'm just trying to think different and encourage others.
