View Full Version : It runs but there are a couple concerns...

1st off, the power steering leaks horribly, but thats the least of my worries right now.
what took so long:
i am an idiot, and put the oil inlet fitting in backwards. had a machine shop clean the threads up and i got a new fitting inserted correctly.
i am an idiot, and used two bolts that were too big for the oil return bracket. i f'd that part up so bad you have to see pictures. i had the machine shop fix that part. now the engine or turbo system dont leak at all. i am nervous about the rear main seal, i saw some oil drops near that area.
fired her up in diagnostic mode. rpms sat dead staedy at 1475-1500. car was loud and there was a lot of smoke. i dont know if thats good or bad. i have a trubendz cat back in my trunk, and my only exhaust at the moment is my down pipe that goes down and comes out just underneath the car. i planned on driving to midas and having them connect my downpipe to my cat back.
anyways car idled fine. a lot of smoke made me nervous, i figured because it wasnt windy at all and my downpipe ends underneath the bay. my AEM wideband o2 guage read between 12.7-13.2 at idle. i dont know whther this is good or bad. input needed on that.
at start up my boost guage sat in vacuum and my egt guage read 250 C. Good?
now heres the other problem (besides the amount of smoke)......i went to rev the engine and it died at the first blip of throttle. i have no idea what would cause that.
my thought: i wired my e-manage off of puckpucks PCM wire file, but it was for a 2000 with a manuall tranmission. I have a return system so that could be a problem. my emanage hooks in the "airflow In", rpm, vss, 12v, and ground pcm wires. i also got the option fuel injector harness to play with fuel. these wires go into the corresponding injectors wires 1-6.
my idea is to remove the e-manage and see if that helps. the only other thing i can think of is that my fuel pump isnt working right. but i couldnt see why as i follwed DanG's post exclusively for that one.
please help i want to drive her within the week. for now im going to remove the emanage and see what happens. BTW i have an ADC chip
thanks

Sounds like same symptoms when MAF is unpluged.... it will run way too rich and at the first touch of the throttle it will die. If you tapped into the maf you may want to temp undo that and try again.

Sounds like an air leak. It's happened quite a few times to me. Check and recheck your air connections. Get some carb cleaner and spray around your air connections. If it revs up you have an air leak there. If you can't find anything start looking at that E-manage but I'd bet it's an air leak. Also another thing it could be is your TPS sensor isn't pluged in. If you reved it it wouldn't know to give it more fuel and it would shut off. Check the TPS wires. I had one short out on me once and a similar problem happened.

12 to 1 is WAY TO DAMN rich for idle.
Idle should by hovering around 14.6-15.0
Matter of fact any no load to light load conditions should be.
Do you at least have your chip programmed to your larger injectors? An E-manage is not going to do a good job at coverting 17lb injectors to 30+ lb injectors via hacking the MAF signal. Talk about a completely screwed up load calculation going on there.
I would not worry about "smoke" unless you see something visibly leaking. Pretty much every thing is going to smoke some for a while after a big project like that. It's just burning off grease, oil, spray, paint, etc.
Prolonged or thick smoke is a problem.
Prolonged smoke out the tailpipe is a problem.
I'd work on the fuel problem for starters.

ADC was supposed to match my 650cc RC engineering injectors to my 90mm maf
i hope they didnt mess that up
i triple checked all air and vacuum connections, nothing is messed up.
im pretty sure it might be the e-manage, cuz the wire i split (one end goes into the emanage, and the emanage goes into the pcm) was a maf air signal wire IIRC
and mt TPS was plugged in. ill check it to see if it is shorted.
going to pull the emanage this weekend and give ADC a call on tuesday. it wont be until tuesday until i get around to started anyway.
thanks and ill let you know

I think we've found the problem.
650cc injectors. WTF are you doing with enough fuel for 800 HP???
650cc = ~64lb injectors. 39-42lb = ~500 HP.
I'm sure the pulse width can not get small enough to idle a small 2.5-3L displacement engine. Maybe raise the idle to 1200 rpm to help some. Better yet ditch them for a sane choice in injector sizing.

Not tryin to make it sound like an easy thing to make a car idle with big injectors...but i know a couple Honda's with smaller displacement than our motors that are idleing just fine with 440's, and a couple even have 720's! :biggrin:

yeah but cougars walk away from most honda's when the coug is stock.
and if your not contrubuting STFU

Don't ever tell me to STFU again! I contributed more to this thread than you did! I was stating that it is very possible to make a car idle good with huge injectors! I am in no way saying he will need those big injectors, much smaller ones will do just fine.
And yes cougars walk away from MOST honda's when the coug is stock...big surprise :crazy: . MOST Honda's have a 1.6 SOHC cam motor that has 120 hp...go figure! lol
I just don't get why people hate on Honda's so much :crazy: . Yes there are some that are slow...just like there are some 4 banger coug's that are slow. Along with some Auto coug's that are slow as well. BUT if you take that little 1.6 SOHC maotor in a honda and slap a turbo on it with 8-10psi i would bet it would KILL 95% of the cars on this board! And i'll take that bet anyday of the week.
Now back on topic...Hey instigaotr have you gottne the stalling problem figured out yet? :cool:

i just keep messing up the little things. i am learning a great deal form my mistakes and if it makes it any better the engine has idled smooothly for about 90 seconds and started right up each time and there arent any bent valves or anything and no knocking, i think ive done pretty good for the most part.
those injectors were justified by my plans to have forged rods and puch the power potential of the motor, i wanted enough fuel to be safe while i maxed out the turbo i have.
obviously things have changed and i dont have forged rods. im going to work with these injectors for now, and do another rebuild maybe next year. i miss my car so much and i'd just like to finish it up just right and continue with my plans for it later.
thanks for all the help

Man i hope you can get that thing running...it should be pretty interesting to see EXACTLY what those stock rods can handle!

another thing, the turbine and housing got reaslly hot fairly quickly, is that normal? forgive my ignorance but i didnt think the turbine got hot that quickly....:crazy:

I'm no expert either but it is running exhaust gas through it so I would expect it to be as hot as the exhaust manifolds.

yeah, burning hot. Glowing red...that can be a cooling issue unless you beat it mercilessly

ya i understand that, i was just surprised at how hot it gets. just a little worried over nothing thats all.

Yup, I've never owned a turbo car either so I just figured it made sense when you said that.
