are you wasted dude?
allright i tore it down today and found i spun a rod bearing.I also have all these hard plastic pieces in the oil pan but checked all the sprockets and they are all there.If you might know what the hell the plastic pieces came from it would be alot of help.Found pistons that will raise it to 9.1:1 from nissan and just gonna get a rebuild kit for the gaskets and get the crank ckecked out from the machine shop.

You probably found a lot of smaller plastic shavings as well, this is what led to your bearing failure and is very common. Like corn322 said, those plastic bits are from a busted chain guide, same with the smaller plastic chips.
Anyway, as far as a rebuild, it all depends on how much you want to spend. Most likely your rods, and crank are all in rebuildable order. Stock rods like noted various times before are very stout and upgrading them is only necessary if you plan to push massive hp and you have a lot of cash.
If you plan to eventually go turbo, the 9.1:1 pistons are probably not the greatest option. They are higher compression for one, and they are no higher quality casting than regular. Pistons are the one thing that you will want to upgrade if you are planning on higher hp figure, na or turbo. So you will have to decide what you want to do. I sell standard oem-style ka pistons (as well as other nissan/toyota/mazda/mitsu/honda pistons/components) in .020", .030", and .040" overbore. The 2.5l high compression kit has been phased out, and a new version will be available soon.
As far as cam, assuming you run a ka24e, pdm is the best way to go. These are reasonably priced, and work very well. I have run a few of their cams and have nothing but good things to say. The c404h is great for na, and in turbo form should work well also.

thanx for the reply d. i am going to go with the lower compression pistons.i am just wanting it to have alot more torque than stock due to tire spinning not building it for drag.it is at the machine shop and they said they would probably just have to regrind the crank and hone the main journals.How would it be possible to get more torgue.....cam?bore it bigger?
thanx alot again
thanx alot again

Wow, I'm a chubby honkey looking "pro grammer" spelling geek? I never knew! I don't care who the topic is directed too, the boy needs some grammar lessons. Looks like you need some spelling ones, need a tutor? **** off.
hey DEVIOUSKA in interested in you all motor na set up,ive been emailin you like crazy but i guess you havent gotten them but what all do i need?whats your current set up?how much has it cost you?if you can get back to me at [email protected] thanks
devious just got news back from the shop, crank is cracked on no3 so im gonna have to get a new one.Question is i want it to have alot of torque so should i find a lightened one or just get an OE spec. have you heard of grinding of the girdle to make the crank caps seperate ones and if so would this be good for a drifting engine, alot of high rpm's.thanx for the info appreciate yur time and effort to help people out.

Hey devious, could you please elaborate on the 2.5L kit.

The 2.5l "kit" is the same as i run in my personal car and is designed for ka24e. Specs are 91.1mm bore (.080 over) 10.5-10.7:1 compression ratio, and an upgraded 22mm piston pin. Only reason im going to discontinue it is because it is a little wild in some people opinions and seems to be unpopular. It will be replaced with a hypereutectic 2.4l (standard bore) high compression setup.
Sliders: basically your only option is an oem crank, find one used. There is no advantage to seperating the main cap girdle on the 240sx blocks.

thanx i found an oem crank from this company for like 261 with matched bearings and im going to get the pistons from nissan 0.40 over going to get 9:5.1. Was wondering about doing an sr swap but i want to keep the ka just more fun to build it up than buy one with more power, my funny way of thinking, call me crazy.Found this guy with a ka24de pushing 524 rwhp and like 490 something in torque......holly crap....with JE pistons,crower rods,and something else internal cant remember.Also if i get the head machined down how much should i go like 20/1000 with those pistons.I think ive made up my mind to go NA.......Thanx for the replies
