Ka24det project

[compactfean]

enthalpy is a tuning company. With your experience .....least amount of boost possible. Let your tuner mess with that stuff, or someone that has a knock light, wideband etc, that knows what they are doing.

[opie240]

Im new to the forum but I know what happens when you take shortcuts. A friend of mine had this idea that he would buy a 240, build it with all ebay parts to prove if it could be fast/reliable . Here are some pictures of the finished project.

SAFC




This happened while he was driving down the interstate and if I remember correctly, he had one of his children in the back seat.

[nissan240boy]

Ok im taking shortcuts but the only ebay part on my car is the turbo and im jyst guessing its an ebay turbo causr I got it free with the car and in my opinion ur friends car had a major fuel leak either due to bad hose or not using correct connectors to cause that pig of fire, that is also y u should keep a fire extinguisher in ur car

[compactfean]

Rotflmao!!!!! Bahahahaha!!!! A fire extinguisher.........got rice? Fml this s*** is funny.

[opie240]

It wasn't fuel man I can assure you of that. But you should build your car the way you want. You asked for everyone's opinions because you needed help and when they try to help, you just say you're sticking to your plan because it's cheap. Be sure you get that fire extinguisher you're talking about.. 2 of the big ones..

[compactfean]

^ word!^ mods lock this thread before we start giving zilvia advice! Lol.

[nissan240boy]

Lol, yea good point, however I am listening to people on this forum since im not getting ebay parts, im using a wideband, im using a tuned ecu instead of a fmu, and im using and 8lb wastegate to keep boost low , I have everything figured out most of it except does the maf go before or after the turbo?

[compactfean]

Depends on if you want your bov open atmosphere or recirculated. If you are going loud open atmosphere than put the maf after turbo....search on here ” blow through maf, if you are going to recirculate the bov back to the intake like stock then just stick it on the end of your cold air intake. Which ever route you choose, make sure to have 6” of straight pipe before and after maf to minimize the possibility of turbulence. Sorry to be an a** but if you feal you need a fire extinguisher than you built the car wrong, lol.

[chucky7]

i can tell you right now what caused that fire his dumbass didnt put a heat shield between the hot a** turbo and the master cylinder reservoir

[compactfean]

Dude I've been rockin no heat shield for like 7 years. if your egt's are that hi to melt s*** and catch s*** on fire than your tune is way off. My egt's barely hit 600 when tuning. Now I'm at a pretty steady 500 ish and that's after beating up on it.

[compactfean]

Oh, and for those of you that like the safc....(which is whats in that picture lol) they can't change timing.....actually they make your ecu think its in a lower load cell (if you are taking away fuel which usually is the case because everyone switches to larger injectors) than its basing its timing off of ” less air” (thats how the safc works, by altering maf voltage) and not the true load of the engine, and tp value. This is what results in to far advanced timing and detonation, or, to retarded timing, high egt's and s*** catching on fire.

[chucky7]

thats because you have a different set up but if you plan on getting on it hard a lot i would put that heat shield on

[nissan240boy]

Okay had a rough week with the car everything gave me trouble, the tubular manifold made my turbo hit my brake master cylinder, so I bough a cast manifold, now turbo fits great, made a custom downpipe, got my aem wideband, wastegate fits good, so I started the car up to check everything and oil started pourin out the exhaust side of the turbo so I ws like watever and orderd a new one, I got my 370 injectors, so I have everything except an ecu which im waiting on, and I messaged jason on ebay if he shipped it and he hasnt messaged back so I hope its shipped and on the way

[compactfean]

You ordered another ebay turbo? Lol you know what the definition of insanity is right? You run a oil restrictor?

[nissan240boy]

Wats an oil restricter?, I just ran a hose from the oil samwich adapter to the turbo then the bottom hose from the turbo to the drain pan

[compactfean]

If you are running a cheap china charger you need to run a .064 oil restrictor, othewise you'll blow out the seals first thing. Google ” turbo oil restrictor” to see what I'm talking about. Even the stock sr20det turbos have oil restrictors.....its part of the banjo bolts.

[nissan240boy]

Okay drivin with no wastegate was a bad idea, the bearing is junk now major shaft play, but I ran a little oil on the bearing and took it for a drive up the rd and boosed 1 lb of boost which I think is because I need a new gasket on th downpipe to turbo so its leakin out the wastegate hole, anyhow I was very impressed how much faster it was with only 1lb of boost, I cant wait till my new turbo comes and im pushin 8 lbs, if I drive around a couple days on 1 or 2 lbs of boost will it hurt anything, I figure itll just ruin the bearing in the turbo till it doesnt spin

[compactfean]

Driving with no waste gate would actually put less stress on the turbo. Do you research before buying or saying anything? Or is it, you just don't know how any if this stuff works? Your car must sounds like s*** with no wastegate!. If you know what a ” bearing” looks like in a turbo you would know that the only way it wasn't gonna spin is if it ran out of oil and siezed. If you are running no wastegate than you will boost zero! Just out of curiousity, how much money have you spent on ebay parts that didn't work right/fit right? Dude if your not going to do it right, you are gonna run out of people to help you.

[nissan240boy]

Ok dude big misunderstanding, im pretty car smart actually, heres how it went, I put turbo on, hooked up oil without a restrictor cause I didnt know bout it, oil poured out exhaust, so I disconected oil and wastegate, so there was no oil goin to thr turbo for 2 days of drivin around and thete was no boost because there was no wastegate, I thought the turbo wouldnt spin at all or very little without a wastegate but I was wrong, after learning bout the restrictor I got one and installed it, then took off.my air cleaner anf discoverd the nut came off the turbine amd kept getting sucked into it and its all marked up and there is magor shaft play, so I decided screw it I hooked the oil up and everything else, also I have sr 370s and emance ecu tuned for my setup and an aem eugo wideband, anyhow I was bored.wating for my new turbo so I put a valve on the incoming oil line to the turbo to restrict it enough that it still somewat lubricated it but dorsnt leak out, then I took it for a drive and boosted 1lb of boost, I think it.boosyed so low cause theres exhaust pressure escaping from between the turbo and downpipe flange cause my gaslet is bad and prolly cause the bearing is work so bad, so to sum it up I ruined my turbo cause I didnt know bout a restrictor and drove it with no wastegate or oil to the turbo and now im just tryin to have alittle fun with my broken turbo till my new turbo comes, also im runing a cx racing wastegate, and I only have 2 ebay parts on my car which are turbo and manifold and the manifold seems very strong, the rest of my parts are aem wideband, emance ecu, jecs 370 injectors, bov of my old turbo ford probe, stock maf, magnaflow cat back exhaust, custom downpipe I made and heat rapped, welded rear I had my grandpa weld.with a stickwelded, full body kit and bodywork and custom base coat clearcoat paint job done by me, also have an autometer boost gauge, stock fuel pump (is stuck pump of for 8lbs of boost on my setup, my valve cover I painted witj flames, I have 2 and a half inch intercooler piping withe a jdm intercooler, so there is me being as thourogh as I can and sry for bad typing im typing on a phone, so I hope that explains to everyone im not dumb and know my stuff but there are things I dont know and I learn on here which is good cause I love learning bout cars so thank you everyone who had helped me, ill try to post some pics of my car tonight

[nissan240boy]

im having problems with the car right now it is missing on two cylinders, im gonna try and figure out the problem tomorrow

[nissan240boy]

Okay engine runs good now, the problem was the sr injector o rings werent sealing and were pouring fuel into the cylinders, I put new orings on and car runs good. Now I did make a mistake when I removed the oil pan and welded a piece of pipe to the pan which isnt big enough I just found out, so I ordered the correct parts and im gonna do it how everyone else does with the 10an steel hose and fittings, now I got my new turbo, it comes with a restrictor fitting in the lf flange, is this ok to use, its basically a flange with a very small hole on the other side for the oil to go to the turbo

[compactfean]

If its about the size of a 1/32 drill bit hole than yes. I see a flaw in your turbo setup though. Your ” drain” is on top. Oil is going to pool up inside the turbo bearing assembly and eventually leak in to the compressor housing, or exhaust housing.

[nissan240boy]

Yea I know that was an old pic, I have the drain at the bottom now and the feed at the top

[nissan240boy]

Aliright guys been workin on the car in my spare time, its almost done, i just got the oil pan off again to do the bung right. Does it matter where i weld it as long as its at the top because i was gonna weld it toward the back side of the oil pan just over top the rack and pinion, there is a lot of room there to run the lines and i can still keep my ac and power steering, so would this be ok, just to clerify i want to weld on the same side that most people do but towards the back of that side, any advice is appreciated, also im using 10 an fittings and stainless steel hose.

next problem which im lost on is my gauge cluster is acting so wierd, first my turn signal would light up when i pressed the brake but that went away now, however now the dash buzzes and makes noise in the gauge cluster, i think its the tack cause depending where the rpms are the noise changes and goes away also the brake light on the gauge cluster lights up and dims out and goes away with the rpms and this sound, is this something to worry about or should i just keep ignoring it?

Okay now i have all parts for my car and heres the list of what I went with-

Stock engine, burns a little oil
welded rear
cast iron exhaust manifold
stock maf
stock ford probe bov, i wanna get an rfl later
cx racing 8 psi wastegate
cx racing t3/t4 turbo
custom downpipe
emance enthalpy ka24det tuned ecu
sr20det 370cc injectors
2 and 1/2 inch intercooler piping with jdm intercooler
spectre air cleaner
aem uego wideband
glowshift egt gauge
apexi turbo timer
megan racing pillow bearing suspension arms

What you guys think, sound like a decent starter drift car?

[spank044]

Videos of it running?

[nissan240boy]

Ill work on taking a video, ok car is running good, really fast at 8 psi, I was wondering do I need to adjust base timing at all or does the enthalpy ecu take care o retarding the timing

[spank044]

The ecu has a modified fuel and timing map to run correctly with the boost. If you change the mechanical timing, the computer doesn't know. So leave the base timing at stock.

[nissan240boy]

Ok got my gauges in today and got some reading, here they are, I guessed idle cause it jumps around a lot, idle was around 15 but jumped around toward 16, at cruising it would jump around like idle but if I was making no vaccum it would run around 14.7, and boosting half throttle is about 13.5 and wot was 12.1, my egts are hot at wot, just 7psi for 4 seconds jumps to 1200, it hasnt gone much over that but im not pushinb my luck, my guess is base timing isnt set to stock, any ideas?

[compactfean]

If your timing is retarded too much, yes it well cause high egt. I, would set the base timing and double check your readings. Also check your base fuel pressure. That can affect your afr. Turn it up, 1-2 psi at a time if needed to get the proper target afr at wot.

[nissan240boy]

Ok I called nissan and they told me to set my distribute 18 degrees advanced from tdc, does this sound right, is 18 degrees advanced from tdc the stock timing and what I should set my timing to with the emance ecu?
