the last 3 months in pics and words, 56k get with the times

[koukiKA240]

Well as some of you may know about mid august the day before a grind event and 3 days before my trip to Europe my motor saw some high revs thanks to a lapse in my own morals and allowing someone else to drive the car. The motor is finally back together and as of Sunday night lives again.

What happened: The engine was overreved beyond what the stock bearing tolerances would allow. Those tolerances were only .001 when they should be at least .002. So its half the fault of the business that last built my motor, and half driver of the car at the time. So what happened was spun bearing. I get the nasty knock sound that I thought was from previous input shaft bearing that finally went bad and I drove it from GGP to kingwood. If I kept the oil pressure up then the rod would not knock, so I tried to do that. Doing that saved my rods and crank which both showed minimal wear at teardown. However pieces of bearing mad it to my turbo and destroyed the thrust bearing which then caused the blades to eat away at the housing. Alright so the only new parts that went back into the motor are the New Nissan oil pump which was only done as a safety precaution because all tolerances were well within factory spec. And a Garrett PKGT32 turbo built to Ivan’s specs from http://www.turbo240.com. The day the motor went bad, me and some good friends busted balls and had the engine and transmission out that night, and the next day had it over at a friends shop and we tore it down to the bare block to find the spun bearings. No pics of the motor coming out, I just wanted it out so I didn’t take the time.

Here are some pics of the teardown the next day.

The first spun bearing with chunks missing

rod that bearing was in, kinda blurry but u can still see the factory crosshatching from crower

head, everything looks pretty normal

oil pan…yum bearing shavings

crower rods CP 9.0:1 pistons, all rings were still good

oil filter taken apart. It did its job but if Nissan hadn’t had gone reverse flow it would have saved my turbo

most of the parts minus the block in my garage

damage to turbine of turbo

After this I began cleaning up the engine parts, everything that could be seen I bead blasted with plastic beads and spray painted them silver. The valve cover I sent off to get candy red, the block got rattle can red as well as the oil pan.

oil pan

valve cover

all engine parts, including intake manifold and the new oil pump ready to go on

block

crank in



new port/polish

ceramic spray painted pistons, after the initial break in of 30 mins of varying rpms they still had the paint on em.

cleaned up engine bay ready for motor

ok so I got a new exhaust too. SSACrap, only $260 on ebay but it does what I want it to and that’s get the exhaust to the back of the car.

old turbo : new turbo

painted transmission

painted intake manifold and more importantly the main engine harness run under the intake manifold runners instead of on top next to the valve cover. The only thing I had to modify was the dist wires, they wouldn’t reach so I added 4 inches to each one and loomed them.

Skip ahead a few weeks now and this is the completed motor we had last week

so hawt

final

me doing the wiring for the dizzy

mine and 2blue240 (henry’s) car, mine is the s13. Just to show what the engine went in.

I don’t have pics of everything hooked up and done but u get the idea from the last one. I left my camera at home when I went to school, but it does run and ran for the initial 30 min break in and then an oil and filter change was done. Next weekend I replace the spark plugs and bleed the clutch pedal and hopefully be driving it around soon.

Thanks to:My gf Bea, Rents, Couch, Pat, Doug (makotos13), ben (Sir_Loin), and anyone else who may have gotten their hands dirty on it the last couple of months.~Sam

Pretty cool man, looks good.

[shockload]

clean car, dont let anyone else drive it and it should be good to go.

[1WheelWonder]

Your engine bay is beautiful.

[Craving4Boost]

good job man...looks great

[crzycav86]

ricer.

shoulda got an sr if you wanted a red valve cover.

[koukiKA240]

that wasnt what u were screaming last night

and thanks for the posative comments.~Sam

[Structure240sx]

looking super clean

[240DRFT]

looks good, wish ny car was that nice...and turbo

[DammitBobby]

Looking good! I am a few weeks behind you.

[S14tat]

yeah that engine is super super super clean.

[Jookmasta]

amazing how spray paint can do wonders. lol. looking good man. two thumbs up.

[EazyBreazy]

i concur with alll previous comments exept the sr one...looks good man

[koukiKA240]

thanks for the comments guys, the SR comment was from a friend of mine, its cool. And i love ur sig pic sdwyz.~Sam

[WDRacing]

Very very nice...

[hysteria]

i want one

[TravBear2]

Mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm...

Sorry had to rub on out there. That was a beautiful motor.

[sunnys14]

thats kinda clean...

[Dano]

Thats hot! You can tell u had a lot of patience with it and took your time!

-Dan

[jamied311]

thats f'n clean!

[Craving4Boost]

wouldnt the spray paint on the block get really hot and chip off? or is it high heat resistant?

[koukiKA240]

high heat, with ceramic of course. Good to 2300 degrees. I dont know of any engine blocks that get that hot unless something is wrong.~Sam

[hysteria]

my car gets that hot. i blocked off the thermostat so the car would get really hot and really efficient.i learned that in thermodynamics.

[koukiKA240]

LOL thats funny, they didnt teach me that in my thermo class.

Hey man, I'm loving the clean setup.

Are you considering doing anything about hiding all the wires, etc? ...To further clean things up. I want to do something similar in my next setup as well...

[koukiKA240]

Thanks, and by hiding wires what do you mean? The crazy amount of wire/vacuum line clutter the 240 enigne bay has running all around it?

The only way i would do that kind of stuff is if i had the money to pull the motor, take all of the stuff off of the firewall and strut towers ect and smooth down the entire engine bay, just get rid of random holes and find ways to run lines and harnesses outta sight. kinda showcar-ish. But this is a daily and i have other projects that need money.

and thanks for thke intake manifold write up, it helped when i was doing mine.~Sam

[fiznat]

kinda showcar-ish.

Yeah I'm torn on the issue because of this as well. I *really* like the ultra clean look, but I'm not sure if its worth sacrificing function just so that it looks clean. Still, this time around I'm gonna make things a little neater-- lol sorta like yours Nice work man.

[koukiKA240]

Yea i hate the fact i got screwed by this guy and had to build it again but i apreciate the opportunity to go back and do it the way i really wanted to. Thanks for the posative comments.~Sam

[knives.kouki]

Keep up the good work nice car.
