Topic: Bad ideas for engine mods
An engine from a 2004 Civic GX apparently has something like hardened valves, rods, pistons, and perhaps other things I know almost nothing about. (1.7l, CNG, maybe a SOHC w/VTEC? ~100 hp)
The listed compression ratio is 12.5 : 1; _designed_ that way to use the energy from methane, which is considered to have an 'Octane' of 120. (from online information)
I'm scrapping this particular GX, since it looks like I could pull the CNG tank and lines, and put them into my CNG van to extend the range; which means I'll have an extra engine with relatively few miles on it.
It's probably (??? - definitely!) an overreach, but I'm thinking about transplanting this engine into another Lemons candidate. Especially since this series seems to like bad ideas in race cars ;-)
I think the idea of hardened valves and other high-compression-ready engine things is a _good_ idea. Makes me want to put a turbo on it.
I've looked at the high compression, though, and a conversion to gasoline (CNG being a non-starter for Lemons racing) would likely require reducing the compression, because from what I've read, even full race gas likely would lead to premature detonation.
I've looked at the first few YouTube videos about reducing compression, so I know that's possible.
Or should I go the other way and fuel it with diesel?
And bring another engine for the race candidate.
Sell it for hardened parts for a different Honda engine?
Or just scrap it with the shell?
