Updates... Rad fan and CEL issues were due to the C101 connector being unplugged. I don't know how that happened. I guess I did it when I was trying to clean up wiring.

I found the bogging issue that I was having when I gave it gas and then let off to have it return to idle. The fuel maps had the a/f @ 13:1. When i ran the ecu in open loop, it would die everytime. I reduced the fuel below 2k rpms by 5%, and now a/f is a steady 14.5:1 at idle and it doesn't stumble when I take my foot out of it. I was using the k20a basemap that came with the k-pro.

There is still more work to do, but its pretty much small stuff that I can do as time allows.

Now for the pics.

I forgot to take pics of the p/s cooler install when the bumper cover was off, so these are afterthoughts

Simple FAL cooler. A cooler is basically mandatory if you want to run p/s with a k-swap.


You can see that I mounted the cooler on the center post that the horn is mounted too. There are already 3 holes there. I just drilled the 4th on the top right corner to mount the cooler. Be sure to put a block of wood on the backside, otherwise when the drill bit breaks though its going right through the radiator.


This is where I mounted the reservoir. You can see the big hose going to the inlet to the pump. The bottom hose goes down through the fender cover/wheel well liner to meet up with the p/s cooler. It fits almost perfectly. I would like to get a bracket to raise the p/s reservoir up higher and move it back a little. I have to keep the reservoir nearly completely full to keep fluid in the big line. Otherwise the pump squeals on startup until its full of fluid. Not a big deal. I'll take care of this properly at some point, but its fine for now.


You can see my modified p/s pump inlet here w/button head screw. This is the stock fitting from my d-series pump and I hacked it to make the mounting flange thinner. I gained about 1/4" of clearance doing this. Doesn't sound like much, but it was the difference between hood hitting, and not hitting...


Be sure to use the bracket that mounts the p/s line to the valve cover to relieve stress on the pump fitting. I had to cut the backside of the bracket and bend it downward to get better hood clearance.


Updated engine bay shot.


I removed the radiator hose insert from the top hose, so got a new hose from autozone. Part #m248.


I relocated the hose insert to the lower hose. The fan switch *MUST* be near the thermostat. The top rad hose is hotter than the lower hose. If the fan switch is in the top hose, the rad fan comes on prematurely and it takes much longer for the thermostat to open (if it ever opens at all).


Here is my homemade intake. Autozone sells this build your own intake piping. You just buy the pieces you need and stack them kinda like legos. I bought a 6" straight, and a 45deg bend. They are 3". I bought a 3", 8" wide foam air filter from www.unifilter.com along with their foam prefilter. Unfortunately the uni-filters do not come pre-oiled, so you have to buy the oil/cleaning kit as well. Foam filter filter great and do a better job at filtering than filters like a k&n. I bought a 3" to 2.75" silicon transition coupler to fit it to the throttle body. Got it from a seller named "siliconeintakes" on ebay.


Pic with air intake in place. Notice the black wire running along the intake. That is my IAT sensor. I just tucked it under the big foam pre-filter, so it is directly next to the filter.


Another shot.


Time to clean up those wires. I mounted k-pro in the factory ecu spot.


Much better. The wires are high enough up that a passenger shouldn't be able to interfere with them. Notice the zip-tie between the blue and green connector. See the little white/blue label on the wire above the ecu. That is the charge light for the hybrid harness. Unfortunately hybrid cuts this wire too short, so I had to lengthen it. No biggie, but if they added another 3-4 in of wire, it would have been perfect.


Same as last pic, just further back. I still need to route the o2 sensor wires, and mount the o2 fuel relay (blue wires). Simple enough.


Time for more hacking on the hood. The valve cover is rubbing.


Valve cover shot. This is the front corner near the p/s pump.


Be sure to wear proper safety gear. The dremel gets hot, so gloves are good. I also don't want my bare skin that close to the flying metal fragments and sparks. Glasses or goggles are a must. I like the glasses because they don't fog up as much as goggles. And a mask. Sometimes the dust is really fine and you don't want to breath that stuff in. I had sinus surgery a few months back, last thing I want is an infection

More wrenchin. One day it'll get done. I have been driving it in the evenings to break it in. I watched the hondata training videos online today so I'll spend the next few evenings getting my fuel tables right.

Here we go...


So I cut a notch for the hood to clear the valve cover and crank the car. Now I hear this horrible screeching sound. Turned out the corners on my cutout on the hood were scratching the valve cover and I was getting a nails on chalkboard effect. So time to break out the play-doh to see where the problem is.


I marked the area that need to be removed.


Final product. I'll go back in and dress up the cuts and paint behind them to get them to match the factory paint. Just don't see any reason right now when I'm still hacking.


Shot of areas that I've cut out. If you look at the top hole, I had to cut out more on the lower left corner to get better clearance on the power steering pump pulley. But looks like I'm good now.


Look what came today. I ordered them a month ago. Found out after I placed my order that they were backordered. Was a little annoyed about that because I asked about availability before I placed the order... Oh well, they are here now.


Nicely packaged inside.


Front setup. They are 10k spring rates which is about 560lb springs.


Rear setup. They are 8k spring rates which is about 450lb springs.


Good bye koni yellows + h&r sports... Anybody want to buy some koni yellows w/h&r sports? Seriously?


Here is the front installed. I need to clean my wheel wells. No clue they were that dirty... Kinda like when you buy new white shoes and then realize your socks are dirty...


Better shot.

Loving them so far. you simply point the car and go. However since I'm still breaking everything in, I haven't really been able to push them on the street. I was hoping to go to Road Atlanta in Oct, but the dates for the group I go with got moved up. So looks like i will be doing VIR in mid October. I will be able to give a full report then

Thanks man. Nope, it isn't running properly right now. My map is reporting really high values when I'm just cruising at part throttle. As a result, I shoot to a high spot on the fuel table, and it triggers the lean protection on the ecu. This causes a fuel cut for 1/4 second. I can turn off lean protection, but I'm glad that I have it on. Might not have found the problem otherwise.

I broke out the helms to diagnose the map and it checks out within spec, but still reports high values. I ordered a new map sensor a few days ago. just waiting for it to come in so i can get this thing back on the road and driving properly.

I've also got a small coolant leak that I need to chase down. It is either from one of the rad hoses or the radiator drain.

I've also got to spend an evening leveling out the car. I need to level it so the height is the same left to right and drop the front end about 3/8".

Its getting there Right now researching tires for track. I've done a few events already and my tires gave up on me. Seriously looking at getting a set of 205/50/15 Toyo RA-1's for Oct.

Are you looking at purely track tires or street/ track. I picked up a set of General Exclaim UHP tires for auto-x use for $55 a tire from tirerack. For the price I am extremely pleased with them. Don't know what you're looking at in tires but I figured I would make a suggestion. BTW the swap is looking good. Great Job! I'll have to look for you around here when you get it running right.

I'm probably going to have a set of dedicated track tires. Part of the issue with street tires is that while many of them do well in auto-x, they start to get greasy near the end of a session on a road course because they never get a chance to cool off. For example, an auto-x run is like what, 1-2 minutes? An HPDE run is 20-30. Falken azenis, toyo t1-s, etc., all get greasy on you Traction was becoming an issue with the d16. Now with a bigger motor and stiffer suspension, I think that I'm really going to have to go with something a little more track oriented.

Sorry... wasn't quite sure what the intended use was . Well it looks great anyway. Would love to have a K20 to show up all my German car snob friends. Again... great work!
