UPDATED!!!!!

VIDEO LINKS PLEASE LOOK
does have open downpipe

http://www.youtube.com/watch?v=gglUXjL956U thought it was the battery but it doesnt always start some reason

http://www.youtube.com/watch?v=ACIY3YC7Cvw some screech sound in this one...not sure

http://www.youtube.com/watch?v=hEsl3HmZF5s just wont idle

what does these symptoms show


ok so i just installed my enthalpy ecu, nismo injectors 555cc, and moved my maf z32 to the intake side and wired it up (blow through)

problem is when i started it up the idle was super rough and would die...if i rev it up it shakes the car i see the steering wheel move....but it wont idle if i dont give it gas it will just go up and down and die

not sure if its timing or what...martin at enthalpy had me set my timing to 20 degrees

im just vary confused i was expecting to not have such a bad idle like this

can some of you experts and guys that know some things please help

i showed a picture of my distributer to martin and he told me to rotate it clockwise a certain amount and i did not sure if thats why i just did what he said...please let me know thanks!!!!!!

i really need this car going by this weekend coming up :facepalm::wtc:

its idling way worse then when it had the stock maf, injectors and ecu...still idled rough before but thats cause the maf was on the turbo and now after i changed everything the car cant idle...

maybe changing the timing was a bad idea but i listened to martin

not sure if its vacuum leak or what this sucks

any help guys? from my reserach i assume its running rich or maybe my timing is bad...i wired my maf and soldered it so i dont think its that...im so confused and idk what to do...btw im young so i feel stuck and im starting school and need this car thanks guys please give me ideas

Ok from my research I assume it's timing. Should I be at te stock 20 degreees or joule I retard the timing? Can I do this without a timing light? Anything I should do when I go adjust it tomorrow? Hopefully this is the only problem

What is the history of this vehicle? Did it have turbo and run fine or did you install injectors, ecu, and mafs to get this bad idle? In my own experiences, a turbo set up with stock injectors, mafs, and stock ecu will still idle and even drive well when kept out of hard driving.

bmar19
08-06-2013, 12:57 AM
Yes it drove fine before. I mean it would die letting off the has cause of the bov open and the idle was not perfect but wouldn't die. Idle want perfect cause the mad was literally on the turbo. So yeah it drove fine nice and easy before I put all this

Waxball you always find me. Lol with all your comments you must be a real piece of work with friends and or co workers. If you have any lol no thanks on the civic my dawg

If it was running fine, or at least better, then the only things you have adjusted after the fact are your problem. Go back and start by getting the car to idle how it used to. Make sure you have no vacuum leaks and your mafs is wired properly. Also make sure timing is at 20*.

bmar19
08-06-2013, 01:43 PM
would a vacuum leak cause this problem? martin said my injector could be bad..imma check that and also i need to gap the spark plugs cause they aren't gaped...not sure if that causes this big of a problem or not and im going to make sure my timing is a 20...all i did was twist the distributer...nothing else..thats what i was told to do by martin

Did you put new orings on the Injectors when installed? Do you hear and high pitched noises at the fuel rail. Use a timing light and set timing. Gap plugs. Check maf.

bmar19
08-06-2013, 10:37 PM
waxball yes i installed new lower rings (the small one) the ones on top were perfect...i lubed them up with dielectric grease and put them in...havent heard noises...the car wont stay on long enough if i dont rev it...deff gonna gap the plugs just got my tool and gotta check the timing.....tomorrow im taking the fuel rail out and just turning to ignition to see if there is any leaks

any other suggestions??? i know my maf has 12V power i checked the wire

bmar19
08-07-2013, 07:49 PM
ok i fixed the timing but now it dies when i rev...upon start up, it goes up and down in rmps and then levels out at 1k.....but when i rev it bogs and dies....plus is the turbo supposed to get really hot after a 45 second idle? the exhaust part of the turbo...not sure if that has anything to do with my problem...im used to NA

heres a video of how it dies

is your setup complete? Like everything connected minus the open down pipe of course? That turbo should be spinning more than that! You obviously have some leaks!

bmar19
08-07-2013, 09:46 PM
yeah its all complete!! crap for real?? so the turbo not spinning is cause of leaks? its a t3 .50 .63 trim :/

08-08-2013, 02:59 PM
is it normal for my car to shut off when i plug in the maf? i start the car and the rpms go from 2k to 500 up and down then evens out..i unplugged the maf and it bogged down but then corrected itself....when i plugged the maf back in the engine turned off....any ideas? im rewiring today but is it just my ground i should do? its not grounded to the chassis...the orange and black wires are together so imma split them up and ground to chassis.....but can anyone explain why it shuts off when i plug it back in...

and my car still doesnt start like as if when i press the clutch the car doesnt sense it and wont turn over at all?? battery connections are good maybe the switch that senses im pressing the clutch is bad?? idk lol

maybe my timing is still off? i assume i shouldnt have it turned clockwise all the way like in the pics???? maybe thats why i cant rev??

you're leaking somewhere. air isn't getting to the turbo. it's not even spinning. instead of spam posting try and look into that...

Suit
08-09-2013, 01:22 PM
is that setup internal or external gate? looks external either way make sure you setup the wastegate properly and make sure the wastegate is not stuck open i mean your comp wheel is barely turning thats all i can think in regards to the turbo not spinning lol

as far as the rpm problems my car did the same thing (idling stupid, dying when given gas) so it may sound stupid simple but find someone with a maf you know for sure is good and try theirs. my car at one point would just turn over and not even fire up, and it was the maf.

bmar19
08-09-2013, 02:32 PM
I'm not spam posting. I'm posting on my own thread through out the different things I face instead of starting a new thread. How does my timing look? I posted pics of my dizzy at tdc compression. Am I auposed to haw it turned all the way to the right?

Also I ran my hands near all couplers and I didn't feel air. :/ so idk about any leaks. Ill look at my wastegate. Is there any links to how to fix or work on a waste gate?? I need to ground my maf orange wire to the chassis I see people do that and sometimes it fixes

So a leak would not allow me to rev my engine? When I rev I see the turbo wheel spin but the car just dies..... It doesn't rev up but spins when I touch gas then falls on it's face and dies. Can't rev up at all

You were also idling at a grand.

you see how much that wheel is spinning at idle from the honda, thats how yours should spin at idle but yours is barely inching along. post pictures of exhaust side of turbo and wastegate

bmar19
08-10-2013, 05:26 PM
Ok I'm getting pics right now. The down pipe is open. Could that be why??? Ill post pics in 5 min. Keep an eye out. Taking them now

Suit
08-10-2013, 05:42 PM
your fine with the open dp, im just seeing whats up with your entire hotside because there would only be a couple reasons why your turbo isnt spinning at idle first and foremost lol. either your wastegate is stuck open/not setup right with vacumm lines or there is a gaping hole in your exhaust manifold or exhaust housing lol or for some reason your turbo doesnt have/isnt getting oil in it so it isnt lubed in the center section of the turbo keeping it from spinning smoothly but if it was the last idea i feel it would have been obvious to you haha

bmar19
08-10-2013, 05:53 PM
if you need anymore pics let me know!! i need to know whats up and what i gotta do lol...did my timing look ok? not sure if you saw those pics from the other day lol thanks suit

bmar19
08-10-2013, 05:57 PM
the turbo spins freely when i move it...i mean i cant spin it and it keeps spining lol but i can move it easily no force

i mean it reved fine before i put in the injectors moved and wired the maf and ecu.....?? you could drive it and it was fine

For the Enthalpy tune, you specified that you have a Z32 MAF correct? If you didn't, the car won't be getting enough fuel because Z32 MAF's output a lower voltage per CFM and would cause your ECU to think your car isn't pulling as much air. Also, I would agree with others that you have an exhaust leak somewhere, I would check your exhaust manifold gaskets. Good luck

bmar19
08-10-2013, 10:36 PM
Ok but why would I have this problem now if it ran better and actually drive when I got it? Yes my ecu is tuned for 555cc injectors and z32 maf

I feel as if my timing is off maybe I'd like input on that. Why would I have exhaust leak if I was fine before? My dizzy is turned all the way clock wise. I think that's wrong ? Idk I did tdc on compression and all that. Check my dizzy pics see if they look ok. Idk. Could timing make my car not rev and not give enough air or pressure or whatever to the exhaust side? My turbo gets super hot after a 1min idle. Te exhaust part of the turbo.

I'm not saying you guys are wrong but the car drive and reved before I installed the maf injectors and moved my mad to blow trough. Intake side.

ok here is the video of my problem guys check it out....its dark but the turbo barely spins...almost seems like a clog type feeling idk weird... but i have video...could it be my maf?? or would bad timing still be the culprit...btw the turbo was pretty hot after this idle....normal? like why would it get so hot???? the exhaust part...even if its exhaust its only a 2 min idle :/ also listen to how it starts up...watch how the rpms go up and down

here is the link

For your turbo, that would make sense that it gets super hot at idle when it's not spinning, the exhaust is working under a lot of back pressure because the turbine is not spinning and the heat is absorbed by the exhaust housing. I would suggest taking off the turbo and checking the gaskets to make sure that they are working correctly and that all the gases are actually going through the turbo. At least try spinning the turbine by hand and see if it feels stuck. Good luck

bmar19
08-11-2013, 11:25 PM
It's spins fine by hand. Like I said before I moved the mad and wired it and put the new injectors and ecu it drove fine with the stock stuff and revved fine. Would my maf keep my turbo from spinning. When I rev before it died the turbo spins fine. But yeah I agree something has to be wrong since it gets real hot. Ughhhhh lol this is confusing

bmar19
08-12-2013, 04:37 PM
Would my fpr have something to do with it??? 555cc injectors with the stock fpr

Also should my car shut off when I plug in the maf?? Or is that bad. I unplug it when the car is on and go to plug it in and it turns off .....

Suit
08-17-2013, 01:10 PM
well first things first we need to figure out the turbo problem because regardless of the dying problem your turbo isnt even spinning so gases arn't moving, so even if the motor was running fine it wouldnt be able to breathe. take a look at picture #7 of the first set you posted. dont know if its a multiple flange manifold or something but that doesnt not look right at all. Definitely looks like you used a turbo and manifold with different flanges. Almost looks like your turbo obviously didnt fit the manifold so it was welding on there lol whats going on in there haha

and i dont know for sure but moving the maf from pull to blow thru may have thrown it out of wack or the maf could have just went out. once you have your turbo spinning and not cooking like a hot plate find someone whom you know has a working z32 maf and swap it for yours to see if anything happes because the way you are describing the maf and spark relationships right now sound like its a bad maf

hey guys, here is more pics of my timing...idk if my dizzy should be turned all the way to the right how it is ???

as for your distributor, setting it pretty mcuh full retard isnt necessarily the best route to go about relating your timing for boost but its a general place to start so it wouldnt be fucking you this much lol. once your turbo spins healthy and all if you really feel like you want to, set it back in like 1/8th inch or less increments closer to the middle, do a pull, analyze results and decide what needs to happen from there.

on a side not feel bad for you man. looking at a brand new build always sucks when things arn't going smoothly, i know those feels lol the final product will be worth it in the end though of course :trogdor:

Ok suit not sure if I told you but the car drove good with the stock stuff having a turbo on it. And it spins fast when I rev just the teeniest bit but stalls and bogs. I see the turbo spin. Just not at idle barely. So you are saying it's only spinning a little at idle cause my manifold Is the wrong fitment? And maybe I can't rev cause my maf is bad correct? That's what I'm thinking but I've also heard timing will also cause your car to bog and not rev. I'm out of commission now so I have to take it somewhere. Tell me what I need to have looked at. I bought the car like this. But installed the injectors. Maf and ecu myself. Since I didn't books it what should I get checked on to prevent future problems and fixing my current ones. Imma take it to a place so I wanna write it down so I can get it done thanks!! I got school Monday. This sucks. Can't wait to graduate lol

So your car was running completely fine before you installed the ecu injectors and moved the maf? like I said before the maf may be reading incorrectly now it is a blow through setup instead of pull through but that's the last thing I would want to say because I don't know for sure if it would disrupt the maf readings, just a thought. maybe it was a shitty tune on the ecu you got? was it one of the deals where you told the dudes your motor and upgrades and shit and they made you a tune for it and sent you an ecu? you can take your injectors and get them flow tested but I don't think they are your problem I think you have a bad tune to be honest. you should sell the enthalpy mail in ecu deal and pick up a apexi s afc 2 and s itc since your not shooting for insance numbers, put the stock ecu in with those and tune it, or if your willing switch to a standalone and retune with a local tuner. I feel like the computer controlled timing is fucked on your ecu since it was a premade tune not live. I could still be wrong about all this though just really seems at this point your ecu has a shitty tune on it.

so here is my word of advice. Try 3 things, flow test your injectors see if they are still good, try another known to be good maf and put in place of yours see if anything happens, and if nothing still happens with a good maf as a blow through, put it back in front of the turbo as a pull through and see if anything happens. if you do all that and everything checks out, I would ditch the enthalpy man. since the car ran fine before it can only be the things you have changed from that time until now as someone earlier mentioned

... So you are saying it's only spinning a little at idle cause my manifold Is the wrong fitment?...

as for this not necessarily but it still just doesn't look right at all haha the flanges on the exhaust housing and the exhaust manifold should be the same dimensions with the same placed holes i.e. the same flange lol your manifold flange is a lot bigger than the turbo flange thats all lol
