Well I finally got my ca running right, idlin, and all that good stuff,(Thanks for the help in pointin me in the wrong direction when it came down to the afc hotwire setting u kno who im talkin bout) but anyway after i got it somewhat tuned. Me and a bro started tuning the car and long story short it seems like one injector was bad and detonated the engine sooooo..... Basically Im lookin for a longblock. As long as the block is good I dont care lemme kno ur prices or if u kno where I can get just the engine.p.s. the hotwire setting on my afc neo with z32 maf was hw1 in and hw7 out Thanx.

could not have said it better. I cant think of too many motors that are more reliable........ assuming popsicle sticks and JB weld isnt the cheif components in your engine install.

Don't forget using straws for vaccum lines, and and dryer ducting for ic pipes lmao

I used a kazoo as a bov once, almost put the ssqv to shame! My buddy is currently using a whoopie cushion. Yeah the CA's are fragile, so fragile I droped mine once and it shattered into a million pieces!!!!!

I still maintain it is 2in 7out. SAFCII, don't know if anything changed between that and the neo version. Of course, when I installed my SAFCII I went to the Apexi site and downloaded the pdf file with the settings. Didn't have to worry about whether anyone was right or not, what with it coming from the horse's mouth and all.

I see the same hate leveled at the KA24. They take a high mileage motor with high compression and a long stroke and throw a ton of boost at it and whack off the rev limiter on the way to PepBoys for knock-off GT-R emblems and when it pops it's the engine's fault.

It reminds me of when a baseball player misses a catch and looks at his glove accusingly like it screwed up.

to be honest I had terrible luck trying to keep that KA reliable under normal driving conditions. it was a total crap machine. Then again, I wasnt the first owner and the first one was kind of a moron.....

I have never messed with a KA, just looked at manuals and read accounts. Upon cursory inspection it appears capable. The DOHC seems well thought out and rugged, good port angles, I don't know what the flow capabilities are but on paper it looks very usable. The rods concern me as to the NA pistons. I would go aftermarket on those, the rest looks fine.

I killed multiple distributors, popped several caps(hehe that sounds funny), and had the power cut out on my mid drive down the block and all power cut out.

on the upside my arms got stronger as I pushed the 240 a lot.

Yeah cuz guys like girls with big,,,,arms.

Caps were bad, the distributor itself was ok, just a bad cap? I know the SOHC Hondas would eat distributors, could never find a D-series engine in the junkyard that still had the ditributor in it.

My KA blew up after 20 years of hard abuse, and no oil changes for a year! (well I just fed it oil because it ate so much and I didn't want to bother with it).Pretty rugged motor, I over heated the crap out of it many times which would have crippled other engines for life, not the ka though! The one thing I hated, and hated over again was the coolant bypass hoses under and to the throttle body. Ironically after many hours of cursing and bloody hands I had changed them all out (after all the cracking for 20 years of old rubber) WITHOUT REMOVING THE INTAKE MANIFOLD AT ALL!!!!!! I'd say that's pretty impressive, or stupid and lazy if you really want to get down to it lol. And then I thought what would be a good replacement..... Duh the CA of course! After all I did have an S12 with the Caet in it years before, great little car. Plus you can't go wrong with older tech! Screw OBD2 lol:D Yay for AFC2+Z32 Maf

I blew the main water line under my CA18DE's intake. Did an emergency reroute in a gas station and never messed with it again.

They appear to be fragile because of unreal expectations from an old/non-refreshened engine that's usually coupled with an owner and friends that are not that keen on tuning. When you experiment, you get experimental results (hit or miss).

no it eat distributors too. just killed MORE caps. tried to figure out what was shorting out, but it was drove me so nuts because of its poor care that I swapped it.

though, word is the dude I sold it to has been driving it at events and still beats the piss out it so maybe in the process of getting a new harness he has sorted it out.

Have you cracked open the one you have? It might just need a basic overhaul, they all do really.

Pistons and head usually take the brunt of the tuning mistakes.

Hah! Im an idiot that deserves to be flamed. Sooo yesterday I go outside and look at my ca hmmmm... wtf the oil puddles looks like its falling from the oil filter.. HAH! I put a greddy oil filter sandwich on it(duh) long story short I took the sandwich off and put the filter back on added some oil and the tapping noise went away. No knock or tapping shes just as good as before I drove her home maybe 1/2 a mile with 25psi of oil. AMEN
