Another KAt lost

[AceInHole]

Doh... that's all I gotta say to that.

How cocky was I when I turbo'ed a stock KA with 140k miles on it?? Apparently a bit too cocky. Anyways, yeah, my engine is gone. #4 piston or rod is gone. At least, it's not at TDC (probed it through the sparkplug hole). The plug itself was undamaged so I'm fairly sure the piston just gave out or something, since if it was the rod the piston might've come up and smashed the plug. Anyways, I'm looking for a new KA to swap in, then i can see if my old block is damaged beyond repair for a high boost rebuild or not.

My life sucks lately....

[silnv]

Sorry about the loss man. Atleast now you can rebuilt it. Keep hopes up!!

[CoasTek240]

dude.. i'm sorry man that sux

u'll get back up on ur feet dotn worry. i'll be on the lookout for a KA

[SR240DET]

iv got a ka from my 95 for sell... you wont be able to turbo it... well.. i wouldnt... its got 112000 miles on it... but hopfully if you want to buy it... itll get chu back on your feet... and your car running... PM me if you interested..

[IchigoMae]

how do yu think it happened? at wat psi were yu running at?

[kandyflip445]

That sucks. I hope you can fix it. What exactly happend with #4?

[96SEChick]

That totally sucks!! Sorry to hear about the mishap :(

[240Stilo]

That sux a lot. Just a few days ago I was telling a friend how he was wrong to say turboed KA's would blow up on stock internals. The reason I was telling him this is because I was going to be going turbo soon but now...If our AceInHole fails what other options do we have? Maybe super high compression pistons.;)

You want low compression piston to run with more boost.
If it's just the piston, can't you rebuild it with forged compression piston?(I think that's what it's called)

[Bbandit]

thats alright ace
life is all about trying new stuff!
at least you enjoyed it :D

ok need to remind you guys of a few things here that ace knew.
You don't Turbo a KA with over 80k mileage on it and expect it to last with a back yard project Turbo setup. Ace knew this and like he said got cocky.
Guys blow up SR's for the same kind of cockiness. Wow it boosts lets see how hard I can push it. Kaboooooommmmm. aw man I am a loser these engines are no good . The guys who sold it to me suck because I blew it up and can't admit because then my cocky ass would be wrong. I will blame it on them.
Sorry just got off on a rant there about a all to often seen familar pattern.
Point is Ace had that cockiness but at least he was willing to admit he knows better,
He is a better man than most. Though he had some innovative ideas and I don't doubt he will build a reliable KA Turbo setup.
He is following down the road that people like Chris May went. Experimentation, leading eventually to a powerful setup.
It does not mean that all is lost for KA turbo's . There are enough reliable setups running out there already.
And your wondering WTF this is coming from a guy who is putting a SR in? Yup I have no bias against a persons engine choice ,likes or dislikes.
KA's have there place SR 's have there place.

[SR240DET]

well put drift freaq... your job is finished here....


:D ;)

I guess I didn't make myself clear. I was trying to say that instead of turboing I'm probably going with high compression pistons.

Right, I just know now that with my 126K mile engine, with stock internals, it won't be the most reliable thing to do.

[Jeff240sx]

Dave,
I turbo'd my car at 83,000 miles, and it lasted 10k miles. It would have kept lasting up untill the fucking wastegate line blew off.
Anyway, Ace... sorry about that.
Do you have any ideas on what caused that? I'm not entirely sure that somthing would just break due to mileage without warnings at least.

[weirdstyles.net]

was it a boost spike.....

:-)


sorry jeff....jus ****in

[AceInHole]

Ok... I haven't spent a lot of time on the engine so I'm not exactly sure what went wrong for sure. I do know that 2 other guys with home built KAt's lost their engines to cylinder 4, but both did so on boost spikes. My engine on the other hand, had no indication of a bad ring or a blown piston. Either one of those would have started with some sign of power loss or bad idle, which I didn't have. I also never had a boost spike.

Here's what I think happened:
Anyone remember that my old turbo blew out on me when the compressor wheel nut came off? Well, the wheels chunked badly, and the bearings wore to almost nothing. All that metal eventually ended up in the oil pan and got forced through the oil galleys after a week or so of driving. This eventually lead to a clacking sound that I thought was valve lash, so thinking it was valve lash, I used thicker oil. Right there was probably the biggest mistake, in retrospect. So, what I think happened is the rod on #4 gave out after the bearing wore down. It's most likely bent, and wedged into the lower block or hopefully the oil pan (didn't look under the car yet, but that would be awesome if the block itself was spared so I can rebuild it).

So, it wasn't really the boost that killed the engine. I'm thinking it was the inability to get the oil and turbo center section changed soon enough, and incorrect diagnosis of the first signs of a problem.

Thanks for all the support guys, and thanks for those that offered help with finding a new engine.

My buddy up here just crashed his S13 though, and is willing to sell his stock S13 engine for $100. There's also a low mileage S14 engine in MA for $300, but I'm wondering if the mileage was a misprint. I'm gonna do a comp. check on my friend's engine and see what it's got for numbers, and also make some phone calls, most likely on tuesday when I have no classes. The car should be up and running again in a couple weeks if things go well. I'm hoping to get the lower mileage S14 engine if it's really only got 65k miles. Gonna be doing a lot of compression tests in the next week.

[240racer]

this should tell all those kids who think the bolt on "kit" turbo setups are more reliable then homemade kits. You still have to get the oiling system to work correctly. They don't come pre-installed. I have had a couple problems with my oil return line and water lines. Both are real close to the DP and they need heat shielding.
Hope that your block is good.
I would think that when a rod bearing is gone you hear some rod knocking that sounds differnent then what I would imagine valve knocking to sound like, but I haven't heard valve knocking so to speak. I guess the rod bearings on the MKIII supra's go out often enough that I have heard two of them with that problem, they sound funny under idle.

Oil it's a wonderfull thing

[AceInHole]

see... my prob was the car sounded fine at idle and under high throttle load... it only rattled around 3k under half throttle.... was really weird.

if you ever hear a knock, rattle, or clank.... stop your car and FIND OUT THE PROBLEM ASAP

[AceInHole]

update on the engine:
I've got 2 that look pretty good:
one nearby for $500 with 74k miles off a '96 and no compression test done on it or possible since the tranny is off of it.
one farther away for $300 with 65k miles off a '95 and did 170 - 170 - 165 - 165 for compression.

I'm leaning towards the one farther away since it has lower miles and known compression numbers (probably dry numbers). I could even buy that engine and my friend's S13 engine, and build up the S13 engine on the side :D I might even still be able to get that Starion FMIC!!

Things are looking good beyond my #4 cylinder.

well... i can get an engine for $200 cheaper with 2k more miles and close enough to pick up or ship cheaply. shipping from socal wouldn't exactly be a lot of fun :p

[Foxcolt]

Every blown KA i've seen (including mine) has been at the No# 4 cylinder. Mine was actually caused by valve float. Either way I still don't know why cylinder No 4 is so prone to problems above the rest. veird.

Good luck with the new motor!

[Grant]

well good for you. i just haven't seen a car babied so well like Greg's

Cylinder #4 is the furthest away from the water pump and oil pump, so oil and coolant are taking the longest paths there, being heated and losing pressure along the way. I don't know the exact oil route, but coolant would definitely be a problem as it definitely has to flow by cylinders 1, 2, and 3 before reaching #4.

well good for you. i just haven't seen a car babied so well like Greg's

i definitely appreciated the info. i saw it on the classified forums myself. it's just that shipping and such is going to be enough of an inconvenience to prevent me from considering it as an option.

[Kreator]

Damn, that sux. Think the fact that you dropped something in the engine when you were working on the head had to do something with it? Hope you find an engine asap.... this makes me worry now.... first jeff, now you. Wonder if my diy kit will last longer :)

Wonder if my diy kit will last longer :) nah. if it was the bolt we lost, the problem would've made itself known early on. I kept checking the timing chain for wear, so I'm sure it wasn't the bolt we dropped.

Like I said... I'm almost positive it was a lack of oil to the 4th cylinder. I'll know for sure when we pull the engine out.

I'm almost positive I'm gonna buy the engine I found in Mass. for $300. I don't think I'll be able to find a better engine for that price.

[clv5045]

I had a ka with 209000 lol, since i bought it to do the sr or rb swap. on the way home it sounded like an exhaust rattle but then beacame more common and louder. seemed too light to be a knock so i thot it was a valve but low and behold it was the #1 cycl. bearing that was basically turned into 3 pieces of paper. my guess is that the bearing was not getting oil/pre-oiled before installation since the kid before me said he had done work to the engine since he bought it from a friend who thot it had a knock. so i ended up having to buy an sr quicker than i wanted to. got it in it ran for an hr just like my ka then blew the seals on the turbo. think they were bad when i got it and i finished em off. just put a new turbo in it and now this thing wont start. has fuel spark and cranks. but wont start.

5 year bump...

Are you serious?

he used the search. Give him credit...:)

[phi_ho1]

holly crap i almost get a turbo set for my KA24DE already. lucky me. RB have some engine and can install it for u. post some pics up if u can.

[clv5045]

i was just agreeing that it is a weird noise and we didnt expect it to be so catastrofic

[chuy]

What you are one of the reasons Im turboing the KA

[slos14]

my shit went pop too i feel your pain :(
