Hey everybody, i was looking at buying a new project car from a local ricer and i was looking to get a little advice. The car has about 125k miles on the chassis.The current state of the car is that it runs but has a rough idle and thedrivers side bank has smoke coming out. The car had a jspec motor installed, all outer seals and gaskets were replaced. It has new nismo 555cc injectors, Ported+Polished intake manifold, Ported exhaust manifold, new vtc solenoids,02's,cam seals,crank sprocket,crank spacer,timingbelt,tensioner,water pump,thermostat, upper and lower radiatorshoses(stillen hard lower pipe),Temp sensors,Turbonetics t-28 turbo's,Ashspec Ecu, appolo front mount intercooler,jwt dual pop intake, dual maf setup, Safc II(custom molded) greddy profec boost controller, Rps segmented flywheel,Rps Max clutch, CZP pivot ball, Czp Clutch line, Engine mounts, transmission mount, Brembo cross/slotted rotors, Stainless brake lines.

Guy claims that he was told that the smoke was an afc error but i severly doubt its a problem the air to fuel mixture. i think that hes either blown an o-ring or a piston head. Has anyone ever seen this problem before? With all the upgrades would it be worth it to buy the car for 6k and replace o-ring, or if nessisary, the block? I know a guy with a sjop where i could do all of the work for cheep, the quetion is it worth it? The car looks real sleek but i don't want a redneck lawn ordiment, i want a car.~Dustin

I have no personal experience but it could be a valve cover gasket or turbo copper washer leaking oil onto the hot manifold and or turbo

Lol thanks for the welcome. yeah, ricers, what can you say. Im sure a little yellow runs through my veins even though im like 8 feet tall and hard core irish looking. I want to differentiate between ricers and racers. Racers are the guys that know what theyre doing and have tuned their car, or at least have some basic idea of how an engine functions. Ricers.....intead of plane out bitching, let me tell you a story .... A guy at the mall by my house tried to drag me in what looked to be a 1996 pasio with a tacked on folgers can exhaust. We hit the line and went. He either he missed a shift or stalled, but as i got to the second light at the quarter, he was maybe 15 feet off the line. When i went to leave he tried a rolling start. i was in second when he pulled up and honked twice. i gave him the thumbs down, he cut me off, braked to like 10 in a 45, swerved back to the other lane and then honked. i let him tap 3 honks out and then i launched and had him by about 7 car lengths. He pulls up rolls down his window and yells, "that was so tight bro, ur such a good driver, what you got under the hood?" im like, "its a bone stock automatic 300zx. only thing i did was use the auto shifter to move from 1 to 2 and 2 to drive." He was stunned and goes, "isnt that car like an I4 turbo or something?" the light changed or whatever and i left. Next day him and his buddy are waiting for me outside of my work. I walk out and hes like, "come on hotshot lets race again, this time with my real car and this time, for PINKS." who the **** is this kid riight? Like, who acually races for pinks, ive never seen that anywhere outside of the movies" So im like, waht the ****, maybe its another pasio i would love a dailey driver so i can just screw with my z. He pulls up in this grand prix gt. Pops the hood, short of the sway bar, and some ****ty paint marks from where he tried to touch up the engine, it looked bone stock. He goes, "its turbo charged!" "im like excuse me?" hes like, "its turbo charged!!" "Im looking around for it, im like, "first of all, doesnt GM make a supercharger for this car, and second, where is the turbo?" "He goes, oh, its on the bottom. But you cant look down there, no matter how you look you wont see it. Its craking out 44psi of boost!" "Im like, thats huge, if its that big i should be able to see it. have you done any cylinder work?", hes like, "no!" So im sitting there and im like, "Well wheres the fuel control? Turbo timer wires, anything like that, with a turbo that big you should be running something to control it." "Hes like "no i just run it off the computer thingy" im like "the ECU?" hes like, "uh yeah!" So im like, "crank the engine then" he like, "no u just gotta race" im like, "then do a looser lap around the parking lot, show me how it handles," hes like, "no thanks, my breaks almost over" "im like, what your backing out? you came to race, lets race." "he goes, a minute ago u didnt want to race." "iim like, well i wasnt sure how i was gonna get ur car back to my house, its too far away ti drive mine and walk back." "hes likkkke, uhh, i gotta go" and he ran off. so tuesday i lef a 10 pound bag of rice on his pasio windshield, and stuck a "property of folgiers" sticker on his muffler.

In the words of Dennis Miller, "I dont mean to go off on a rant here but..."

Loved your 240 pic, what are you running under the hood? Drag or Drift?

PeaceDustin
