hey i threw my first rod and i made the worst decision ever and that was to try to limp home ....that means its time to rebuild my first engine and make some improvement..im prety shure becuse i tryed to drive it like that i fucked my engine up to much and think i just need to pull one and start from there..

that brings me to my first question ... my brother has a 94 altima and i have a 92 240 we both have the ka24de motor but ive knowticed a few differences like the position of the distributer is this becuse of the fact that its a fwd and mines a rwd o ris it becuse of the year of the engine itself .....also how will this affect my engine shoping (will the engine in the alt still bolt up to the tranny)

after that im still on some what of a budget and was woundering what some of the more worth while things to do to the motor while i have it apart( deff not gona cheap out on the rods and pistions but other than that i dont realy know what dose what inside and wanted to get a few basic upgrades until my smarts catch up with my driveing then build it again.

right now im just trying to get my game plan together and tips are very much appreciated

 

Get a new block or motor set. Motorset would be my best bet because of the time issue, but if you want to wait. good lock

expect to spend in the area of 400-500 for a good running ka.

You need an S13 KA24DE

 

240sx KA24DE. S14 ones will work too, just reuse your old intake manifold and distributor.

Truck KA's have the dizzy in the block, and FWD ones are different too. You shouldn't have any trouble finding a 240sx KA.

 

haveing a lil more trouble than ude think... if i were to use the 3 14 why would i need to reuse the intake manifold and distributer? j/w and thankyou for the responces...ide think if the were gona make the same motor different it would have a sub modle number

 

s13 has butterflys in intake and different sensor plugs. s14 distrib has a built in coil its not external like the s13 is. u can make it work but that is not worth it to go s14 distrib. the intake can work with modifying it to.(i never tryed it i just use the s13 intake/distrib and call it done)

 

thanks and it looks like i found my block ... i am planning on building it up and tearing it down 2 or 3 times to upgrade it ($$ issues) this time i wanted to focus on the ka probs like the shitty rods that broke out in the first place and new pistons aswell i know i wana bore the holes out and get bigger ones to (i dont plan on cheaping out eaitherfor two reasons)i was looking at the bc sires forged steal pistons that look all cool and shiney witch is all good and well but honestly

i dont know that much about motors any info on the main parts what they do and how they effect the over all power of the motor would be great..
i know theres the cams pistons rods crank timing chain valve springs tentioners and pullies that could all be potentialy be upgraded(based on after market parts sites)

on my block i read that i could also improve on the ka's exaust ports ... something about there angle ide like to improve this but i dont know what they are refering to or how to modify correctly

as always help is appreciated

 

Dude good luck with that. I had to do the same not to long ago

 

dude, seriously, I appreciate the enthusiasm, but maybe you should step back and really learn something before trying to throw some money at this thing otherwise you're gonna end up with an expensive pile of parts.

learn about engines and how they work.
learn about how to get power out of engines
learn what makes good parts good and cheap parts crap.
learn the difference between inexpensive and cheap
learn the amount of work and time and money it takes to build an engine
learn what exactly goes into rebuilding an engine. There is a little more to it than just bolting up a bunch of parts.

once you know all of that and have a working understanding, then start looking into your options.
in the mean time, just get a running motor. If you want it to last a while, then take the head off, replace the head gasket, send the head to a shop to get it cleaned/hot tanked and planed. Very carefully bolt it back up. It sounds like a rather simple head gasket job would teach you a lot about working on an engine. flush all of the fluids, get good spark plugs, new wires, cap, rotor, all of that good stuff so you have a healthy engine.
Learn how to drive. Your comment about "my smarts catch up with my driveing then build it again." was rather unnerving. Its like you know you can't drive for shit and you beat on engines and just expect to build a stronger engine that can handle the abuse. It doesn't work that way. Quite the opposite actually. If you aren't going to cheap out on parts, by the time you buy rods, pistons, a new crank, get it all assembled/balanced/machined/installed, you're going to have spent over 2 grand, easy. The way you are talking, you're just going to beat up on it until it blows up again...? You said the stock rods were crap. I'd bet the guys running about with 15+ pounds of boost on stock internals would have something to argue about that.
Not trying to be a dick, just trying to point out just how much you need to learn, and actually understand, before you just pick up a wrench and go.

 

You're doing something wrong. I'm 100% sure mine have seen more abuse than yours and I haven't experienced any failure.

 

yeesh.
yeah man. take a step back and think, "am i doing this right?" "is there a way that makes more sense?" then follow that path
