Pulled right out of a 240 and put on the stand.  The piston rings were blown and it was blowing smoke.  The valve seals were also bad.

Started to take everything off and clean it up.

Why the hell I decided to paint it red I don't know really know, it was one of those ideas that seemed kinda cool and ended looking really stupid.

Some new bearings.

The silver turned out looking blue, also a bad choice.  It doesn't look so bad now that it's a little dirty though.

Put everything back on.  The pistons were also replaced but I don't have pictures of that or the very annoying valve seal replacement.

Got a new waterpump/belts/timing chain/thermostat etc.

Getting ready to put the engine in

The wiring set up is all taped and tucked now.

And there's the swap, running pretty solid aside from some leaks  :shifty:

But yeah it wasn't too hard and it was fun.

I think your being a little hard on yourself about the paint colors. I think it looks fine. Nice job man. I love my ka-de hatch! Great inexpensive choice for a solid engine. Unfortunately though a lot of ka's are often worn out from abuse. Overall though its a much more practical option then spending a bunch of time and money modifying a ca18et or ca20e.

We went with a red/silver/black theme on the VG33 we put in my wife's pathy and i thought it turned out great.  Keep up the good work.

I am gonna get them powder coated white eventually because I cleaned them up and it looks like the clear coat started to come off and they look hella dirty

So the time to fix my idle issues has come.  My injector flow was higher than stock for each injector as well as a leaky one, so I ordered brand new ones. None of the idle control was working, AAC, IACV, etc etc, so I got all new sensors and what not. The only problem right now is the new AAC valve uses the same plugs as the injectors and are different than the ones on the harness so I have to go to the junkyard to get some plugs off of some other nissan.

Those plugs are readily available at parts stores or on line & inexpensive, so get new ones!

Yeah it's going to run greaaat, can't wait to feel the results

Noah, what paint did you use to paint the block? I think I am going to do that but to match the color of the blue car.

IggyEGuanaDec 12, 2014, 7:51 am · #17

use gloss black engine enamel

Noah ADec 12, 2014, 2:58 pm · #18

It was just engine paint from pep boys

WonderingravenDec 12, 2014, 3:46 pm · #19

Gotcha,

Noah ADec 13, 2014, 12:53 pm · #20

the valve that's supposed to be in the AAC wasn't even in the old one lol

Noah ADec 18, 2014, 8:50 pm · #21

something isn't right. For one I think I may have the heater routed backwards on the KA. Also, the car starts okay now but idles at 15-1600 but doesn't go down afterwards. The AAC valve plugs were changed so I had to get different plugs, but when I wired them in I didn't know which wire should go to which on the different plugs, or if it even matters how it's wired. Anyone have any pictures of the KA/s12 heater set up or know anything about the wiring? I hope the idle control circuit is even getting power >.<

So the AAC valve I ordered is from an s14 KA, and mine still uses a single cam ka one, and they are calibrated differently and thats why the plugs were different

classic nissan

i don't know why you say "classic nissan" - that seems to be a pretty good idea in my opinion - if it doesn't plug in there's a reason.

good info to know
