the long overdue Specter's KA24DE rebuild thread

okay... let me just state that the car is running as we speak, these pics are kinda old and overdue. there are more of them however i just need to get off my lazy ass to get them.

okay as some of you know before christmas last year i blew my engine in my 92 Nissan 240sx... in a sence it puked all it's oil and spun a rod bearing...

anyways a full rebuild was commenced. and with out further delay here are the pics...


removing the head off the old block


grr... damn you lower timing chain


head dissembled


ooo new paint... and rice


well there's yer problem... seems there was a little more going on then a spun bearing


for anyone else doing this rebuild... remember to install this plug, apparently it's the darin plug for the blocks coolent... doh


engine in car finally


4X4-ing


like i said there are more pics... i'll just add them later

thanks for looking... next step is ITB's

Dope dude u took a part a twin cam, i gotta do the timing on my car im just to scared to take anything apart thats timing related.

this looks like a guy that WOULD have this


as his avatar. . .


hahahaha


i keeeed. . .. . i keeeeed. .

least i don't have an overrated clothing co.

Did ya just rebuild or did ya add some goodies to the KA?

well basically it's all stock except for the new bearings, rings, and seals. however i did go aftermarket for those. yay ability to hold 20lbs of boost

Eeeexcellect!

isnt a ka in its stock form capable of running that much??

idk on that.. about the only thing i've heard of was 10-15 psi on stock...

but this on these bearings i know i can safely run 20 psi without issues

u gona boost it? if so wouldn't u need stronger internals for it? wahhhhh... time for me to do more researching on KA-T.org BOHEEE

stronger ineternals never the bottom end on a ka isnt half bad I'd trust up 2 or close to 20psi on that bottom end

and the only reason you see built up bottom ends on ka's is because whoever runs a ka-t is usually boosting near that or more matter in fact the only people ive seen with ka-t's are like 20 plus psi

I guess its cool to always have a crisp running car atleast. Cause i dont even have a heater..........

It is true that some people have managed to hold 20 someodd thousand lbs of boost on a stock block. But for how long? Rings and bearings are not the weak point of that engine the stock piston ringlands are. It can be done if the car is tuned carefully, but the slightest hint of knock is going to start disintegrating the ringlands. From what I have read, about 12psi is the max for a reliable stock block.

As for the stock rods, there have only been a few cases of throwing them even with good amounts of boost. However they are fairly long and kinda spindly. I figured while I was in there, better change em just in case I miss a shift and overrev. Do it right or do it twice or more.

^ True. But from what I've read, you really don't need to boost really high to get some decent power out of The KA.

yeah i was not planning on boosting anywhere's clost to 20psi

and i'm well aware that the bearing and rings are not the weak-points

Also very true, with a stock compression ratio of 9.5:1, only 10psi has been able to net close to 300whp.

lol, no way ur gonna safely run 20lbs boost on that motor. There is a reason i built mine.

8.8:1 FTW lol

you didn't read the part where i said that i was not planning on running anywhere close to that did you???

reading > you

no i actually read the whole thread.

I was laughing cause u think u can run 20psi.

Totally different. Toootally ( biodome)

Don't mean to rain on your parade Spec, but yeah ya did.

And ATOWN: Try and relax a little. I've been readin yer posts and it seems your flexin too much muscle around here (this site). I'm sure I'm not the only one who thinks so either.

it really does not matter anyways considering that i will be going NA...

you're just pissed joe that i'm faster then you and i spent less money getting there

not really lol.

I'm happy w/ my motor and ur faster cause i've got lower compression.

In the long run though it'll all be worth it

And me flexing my muscle? Na me and specter are straight.

TANDEM at my house again! lol

Yesterday, dude pul a 180 into the parking spot. Eh u pulled a 45 lol

we really need to find an open parking lot

^ definately.

lookin good on the rebuild
