ka24de motor prep, input please..

Hey guys, this is my 1st post, I'm about to pick up a motor that i bought for 300 bucks. It has 69999 miles on it and i'm getting it for 300 bucks. My goals are: Install clutch, break it in and then turbo it, looking to get 220-250whp.

I'm not going all out with boost and will only run 7-9lbs and maybe 10 if i can get to it.

my setup: ssa manifold/dumppipe t25 sr turbo/370 injectors walbro 255lph safc 2 touge factory 3 inch downpipe s13 sr smic with stock bov z32 fuel filter mbc

Basically i'm gonna run the same setup as bluebottlemax

Reason for lower mileage motor: well my car has 180k on it and i'm getting the motor really cheap and the turbo and injectors are going to me for 100 bucks, the safc, downpipe, smic/bov is also going to me for 350 bucks(new), and i will buy the manifold,dump pipe, and walbro from ebay ($300). Gaskets, lines, and fuel filter will prob be $150. 900 bucks total for turbo kit... not to bad

with this setup, moderate boost/power, with little/no turbo lag will be used for autox/drift events.

questions....

While i'm doing the motor swap, i would like to know what I should do while the motor is out the engine bay? I would like to do preventive maintance stuff and not anything crazy like a whole rebuild...because i will eventually/slowy rebuild my 180k motor and have it for a spare.

I know that i will be replacing the rear main seal since i already have the new clutch ready for install... front main seal will also go in. is there anything else you guys can think of that will not put my bank account in the negatives?

Also, the motor was probably sitting in the junkyard for 6months or more, is there anything i should do to lube the motor? Is it necessary for me to drain the oil, pull the valve cover and flush new oil through it? should I change the plugs or just swap my current plugs in instead of getting new ones? Should i also replace starter, alt, water pump with my current ones? should I remove the iaiv valve, egr, etc?

please let me know what should be done with the lowest amount of money involved...

thanks a bunch...

Do you know what year the motor was produced in?

Dealing with any motor swap, I would flush the oil and coolant. Also I would definitly replace the water pump, thermostat, plugs, wires, and distributor on this new motor. The starter and alternator can always be replaced afterwords, if there are any problems found concerning those parts. And yes i would remove the EGR valve if you are going to turbo the motor.

i would be VERY surprised if you made that much power with a T25 a SMIC....

yes yo are right, smic will not cut it....i should of specified that i will aim for 200whp with the sr parts(smic, bov, etc)....then i'll upgrade to a ebay intercooler, customize piping, greddy type s bov, etc, and then my goal will be 220-250whp...

thanks for the correction...

oh, the motor is from a 95 base model, no power locks, 240sx....I just picked up a new valve cover gasket from nissan.....anymore input? i really dont want to take the motor apart....

thanks

Ok, today I took off the valve cover to see if any creatures were living underneath and I found OLD OIL THAT TURNED INTO SLUDGE/CRUDE....IT WAS LIKE black jello... :tweak: :ugh:

here are picsThat is some of the jello oil that i picked off of one of the cams.. :-(Do you see how glazed the oil looks?

I'm assumming that the oil turned like this because of the motor sitting very long and the oil wasn't circulated at all.... the oil in the pain is still liquid though....I plan on switching my current valve cover to this motor... When I do switch them, I plan on pooring some oil over th head so the motor can be lubed... do you think its ok if i swap the motor, hopefully crank it, and let it idle for 5-10 mins until it warms up, then shut it off, and drain the oil? Do you think the sludge would clogg anything up?

Also, any other info would be greatly appreciated..

thanks, you guys are awesome

your still thinking of puttin that in after you saw THAT.....?!?!

lol.....don't put that motor in!!

rebuild all the way man.....i wouldn't want any motor that i'm going to put stress on in the form of boost (especially 10 lbs) to look like that before it went in.....do a compression test on the motor in ur car now and consider running very light boost on that one for auto-x or something and rebuild this one....

if ya need any help i'm always on AIM and there's a ton of knowledgable people over in the KA-t forums

Tell me why he shouldn't use it ? I'd like to know. I'd like to know why other than just the oil too.

i heard using diesel fuel inside the engine will clean everything out real good. anyone know if this is true?? it will smoke for a while and when u are done running the engine u drain all the oil and put new oil in.

uh for one the oil.....did you not the gelish type crap it looks like now? thats just not healthy for a motor that's gonna be boosted and the other more obvious reason

the motor was probably sitting in the junkyard for 6months or more

he doesn't know how long it's been sitting....it's out of a 95 and it has 70k on it...which means it could have been there much longer....no one knows for sure....but with a motor like this, one that you don't know if it came out of a running car or not, it's much safer and smarter to NOT PUT THIS MOTOR IN...why go through all that time and effort of pulling the old motor and dropping the new one in only to find out that it won't crank or doesn't fire? Well there goes one day....o wait, now ya gotta put the working one back in! FUN! another day gone swapping the motors back? i'm definately not willing to take that chance.....

rebuild this one for more boost and give lighter boost to the one that's currently in if you feel it's necessary...don't rush a KA-T project...it's not worth messing up an investment as expensive as this...

nismo240sx, there's a motor down the road from me in another 95 that's in similar condition, sludge and stuff all over it....if you feel like you can prove me wrong...it's $400 with a 5-speed transmission...

thanks for the advice guys, the car was in a wrecked car and the car was on its correct side, the wreck was on the front driver side corner and was not that bad, but i've decided to take this motor apart and do a stock rebuild....i'll up the pistons to forged ones and use a better head gasket. due to lack of funds, it might take me 2-3 months to get it rebuilt though... anyone think its a good idea if i rebuild it outdoors beacause I dont have a garage or any covering... i may just by a tent and put it in the back yard and cover everything up with plastic or something...

thanks again...
