I bought my 1992 Honda Prelude Si for $1100 in February 2005 with 198,000 miles. The labor cost of the entire engine/tranny swap was about $1550. The bushings took 10.5 hours to install due to the difficulty in removing the old bushings after 228k miles. In February 2012 I spent another $900 in labor (tuneup, brakes, climate control repair 244k/41k) and $550 in labor during the remainder of 2012-2013 (master cylinder, sensors, distributor, etc 245-249k). I have only been driving it a couple times a week for the last 5 years or so. Now I am looking to sell and get something AWD for the winter weather; my wife has to drive up a mountain to work. I wish I could afford to keep both, but we are paying for my wife’s Lyme Disease treatment right now.

The Good (cheap, reliable, and fast…..almost….):
This car runs like a top and provides all the fun I care to have on public roads. It has never left me sitting since the swap (the old h23 timing belt incident below was the only time it failed me since I bought it in 2005). I have only had minor issues expected for any car with a few miles. I care a lot about my vehicles, and though it may look rough around the edges, I have never neglected mechanical needs or maintenance. I’m a very spirited driver (the car was built for it), but I never rev above 2500-3,000rpms until it is fully warm. It has NOT used enough oil to need any extra between oil changes, but does sip a little in VTEC (worth it, but I generally shift shy of the notable crossover point). I always run premium fuel because of compression ratio and tune. The car has a bunch of new sensors and small things people don’t think about changing on the regular; I wanted to keep it running like it is supposed to! They don’t make them like they used to, get it while the getting is good! Cable throttle and cruise control!
The Bad (all problems I am aware of):
This car could use some paint very soon. The passenger window motor recently failed; my mechanic confirmed it’s the issue rather than another electrical problem. I have not ordered a motor, but I installed window visors to cover the 1 inch gap present when the motor failed. There’s some hail damage and a large dent behind the passenger door (predates my ownership). The trunk leaks a little in hard rain, could be sunroof drains again and/or tail light gaskets. It has some duct tape trim on the inside, but it matches the paint! It has regularly returned 27mpgs. My mpgs had fallen to 25ish, but much of the service (244k-249k) was an effort to improve this figure; it has, provided I’m easy on VTEC. Because it is lowered, it has some toe out in the back that cannot be adjusted in; this does wear the insides of the rear tires a bit extra, but seemed to reduce understeer, so I left it alone. The spoiler is currently off and holes siliconed. The antenna is gone (siliconed), but I think the wire is still there. I just use the CD player. I installed decent kenwood 6.5s in the front, and some mediocre rear speakers.
new genuine Honda clutch pedal cover
fuel filters and oil filter mentioned above...dot3, honda ps fluid
stock shifter (not installed, the short throw shifter is)
2x high beam replacement bulbs
1 low beam replacement bulb and 1 OE corner light cover (one was broken when I bought car)
I still have the spoiler… I plan on keeping my “blueridge” shift knob, but have the stock knob
Biography (keep in mind the engine has been swapped since the timing belt issue!!!):
When I bought by prelude, I guess it was my best birthday present to myself. I loved the H23A1 even though she was a heavy (oil) drinker and scared me once when the timing belt came off (without warping the valves!); I never regretted the purchase, and never doubted that I got a great deal. Eventually I was having to add a quart of 20w50 every ~900 miles of driving, and thought back on a not too distant memory… the cold cold morning I added 6 quarts of 20w50 (or should I say molasses) on the 18 mile trip to the mechanic when the seal above the oil filter decided the time was ripe for self destruction. This small tragedy inspired images of an JDM H22A driven Lude with LSD, a good tune, and fancy, albeit normally aspirated, “bolt ons.” Blueridge motorsports helped turn this image into a reality earning a regular customer and friend (not advertising; they now run a plant nursery). The car I loved before has been transformed into a trusty reliable daily driver that made the Si I remember so fondly seem like a shadow, indicating greater things to come.
Total cost I paid for the car $1100
Total cost of parts starting with the engine/transmission swap ~$7900
Total labor costs of extra work, discluding oil changes etc… ~$3000
Total = $12,000; I only hope to recoup half the cost of the car and parts, so I am asking $4500

jdm p13 vs eCtuned p28 dyno chart
see the nice gain in torque through the lower part of the band? car pulls from 35mph in 5th gear now without any complaints... I don't usually let it, but it can comfortably cruise along around 35mph.
peak numbers are just that, peak numbers... they don't speak to how much difference was really made with the tune... people who have rarely ridden with me have noticed the additional power.
