1998 Civic LX to HX D16y5 conversion has begun!
I have given up looking for a CLEAN HX in this area. They're either completely trashed and asking way too much or are clean but asking way too much.
I decided to just get a complete D16Y5 and swap it into my LX. That way I can keep my A/C and cruise control.
I have gotten a best of 37mpg in the D16y7 and would say I average ~35 which isn't bad considering I do zero hypermiling at all.
I didn't get the longer geared y5 transmission. I am going to stick with my y7 ratio'd trans and see how it goes.
I will be installing this 100% complete and will even make the *useless* upshift light work.
Here's the motor / harness / ecu I picked up today and believe it or not the exhaust manifold has NO crack!!!! Hooray!
T-belt, valve cover gasket, oil pan gasket, rear main seal, cam seal, front crank seal will all be installed before dropping this engine in.
I plan on having it up and running by next weekend.
I'll report the change in MPG *if any* on this thread so people in the future can decide if this swap is worth it.
My calculations say that if fuel is $3 a gallon and I gain 6mpg by doing this then the conversion *Total of $650 including all new parts being installed* will pay it self off in 56k miles.
Bear in mind, I am into the LX ~$1500 dollars so by spending another $650 i'll be into it $2150 and there's NO way to find anything still resembling a HX around here for close to that price.
The other side to this is the Y7 will get Vitara's and rods and a full refresh while out. I'm going to be building it for boost along with a chipped p28 ecu and will use that in a year or two for some fun racing at the track so the Y7 being removed won't goto waste.
