Hello so i have ran into a few problems on my build. History its an 02 with srt4 head swap srt4 intake and trottle i had to have head work done so i rebuilt the engine and did work on yhe engine bay. And have put everything back together plus added turbo although i havent hooked the turbo pipping up yet. I tried to add a msd disc 2 plus witch didnt work for some reason so took it back out. And hooked the factory coil back up and it started but during this process of tring to get it to run we noticed the when the key was turned to the on position there was a humming noise coming from the engine so i found where it was coming from the IAC when i unplued it it noise stopped. Dont know if thats normal for srt4 IAC. Also i do have a safc hooked up. So after putting the stock coil back on the car started up but has a ruff idel it jumps all over the place but mainly sits around 1200 rpms and the IAC still has a humming sound. I dont think the timming is out bc i dont hear any spark knock and im not throwing any code like i was at first when i had the msd hooked up i throw codes p0508 ? P0123 tps volt and p1685 key skim. I dont know what the p0508 is for its not on the list of codes. But mow they are all gone and have no codes but still runs ruff. I have check all harnesses and grounds i just lost. Now here come the kicker after starting the car when i let off the clutch the car dings as if the door was open with the key in the ignition but the doors are closed and the axle starts spinning and speed odmeter raises to 10mph. Really need some help from the neon gurus please. Please please i miss driving my neon and really want her back on the road.

Update
Car is now running smooth i took the IAC out cleaned it but still makes a humming sound. Safc is hooked up and seems to be running smooth with it. New issue got a tappng sound coming from belt tensioner it seems to be jumping back and forth. Is it suppose to move or is that alignment thing suppose to stay still i do have videos of the tensioner if i can get it to upload.

The IAC humming is fairly normal. Usually you can't hear it with the engine running.

The timing belt tensioner does move a little, more the slower the engine gets. It moves all over the place when turning the engine by hand. That is why it should be set at TDC, so the cam lobes are positioned correctly.

Question do i need to have a oil cooler for a turbo build? And would a transmission cooler work bc these oil cooler out here are expensive for a budget build.

An oil cooler of any type is definitely a plus!
You mentioned a transmission oil cooler, I'm assuming your running an automatic. Then "YES" run an auxiliary trans cooler as it will help cool the fluids off since your adding a major additional load to the transmission.
As for an engine oil cooler for the turbo, the same principle still applies, the cooler the oil the better Rock ON

I am running a 5 speed but was going to use a trans fluid cooler to cool the oil coming off the turbo

k, the way the post sounded "i could be wrong" is that you wanted to add a trans and oil cooler......
Anyways, YES the cooler the oil to the turbo the better. Which means running the pressure hose from the block, to a cooler and back to the turbo. The thing you need to be careful with is the hose diameter as you want to try to keep a steady pressure to the turbo so it does not lose lubrication. So for example you have 60psi of oil pressure leaving the block and it drops down to 55psi when it hits the turbo, you don't want to lose this pressure by running 3/4" hoses down to a cooler and back to the turbo because there is so much of a pressure drop the turbo would lose lubrication.
Maybe using something like a power steering cooler setup will help keep the pressures tight, but then it boils down to is the 10deg temp drop actually worth it? If you could drop the oil temps 20+ deg before entering the turbo with minimal pressure loss then I would say do it!!!!

The best answer for this is to google search reviews on BOV's...

Ok so here is the new issues i have the turbo installed and running now when i tap the gas more of a bump i hear this strange noise sounds almost like it comes from the valve cover that wasnt there before. This noise came after hooking up the turbo piping. Any ideals what it could be?

Edit: ok found the noise it was the pcv valve.

2nd. I now also have a vibrating sound coiming from where the battery use to sit i cant tell if its coming from yhe turbo its self or the transmission only new things i have done was put atf in the transmission and install turbo piping. I dont know when they switch to atf in Manual transmissions but my car is a 02. I have checked around the turbo piping and cant find where the noise is coming from. Any ideals what it could be?

Edit: it is the transmission sounds like a gargling sound. See i beleive my transmission has gear oil to start with.

How do i check to make sure the turbo is getting oil?

Edit: now im throwing a code
P0172(M) 1/1 Fuel System Rich A rich air/fuel mixture has been indicated by an abnormally lean correction factor.

I do have a map clamp that i havent started messing with yet. Does that code mean that it detected the boost and added more fuel because it was leaning out ?


Thanks for all the help i am new to the turbo world and will learn as fast as i can about them.

you have quite a bit of misc questions Rolling Eyes
To me you need to sit down and breathe Laughing
I was always in a hurry to get a build done and there were always things I would miss. One thing I learned before taking my car for a drive was to start from the passenger side of the engine compartment and work my way around to the drivers side double checking everything incase I may find something I missed during the build.
Electrical wise I would always miss a ground somewhere. There was one time I actually forgot to ground the headlamp to dash harness at the radiator core support and my wipers started working Laughing
Make sure you do a complete once around and see if that fixes any of your bugs Rock ON
Also note when it comes to the PCV system, since your boosted now you have to reconfigure the system a bit to help evac the motor better. I made the mistake once of plumbing the pcv to the intake manifold not thinking that the manifold is going to pressurize and since I did not have another way to evac the block I blew gaskets out everywhere on the valve cover(note this was with a 2.2 Turbo2 motor and not a neon)
Hope some of this info helps, please post back if it doesn't
Smile

I have looked this car over and over all items are hooked up. I dont know what i did but messing with the map clamp and safc i seemed to stop it from adding fuel and throwing a code . But the new thing now is during one of my start up it almost sounded like the tubro sound was in the valve cover but after a min the sound went away. This happen 3 times. I drove the car and it doesnt seem to be getting boost. Still feels like stock even with the pedal to the floor. How much boost does a stock srt4 turbo make and at what rpm should the boost kick in?

Edit: just throw another code on start up for some reason it is haven a ruff ruff start up say its lean and adds fuel which causes the code p0172. Why would it do this if its not seeing boost yet at idle.

Edit 2 : so i put the factory 02 injectors back in and come to find out that one of my injectors wasnt put in all the way so might of had a air leak which might of caused the running lean. But with the factory injectors ran good without boost so i then add the boost back and still ran good. Took it for a drive and everything seem to be fine. I used my scan tool to take some reading while driving. During my drive had no issues no lack of boost no hesitations ran perfect. No codes yet. Now how ever here is the kicker. The scan tool showed i had a pressure of 15.2 in the intake manifold at about 6000 rpms . This just gets crazier more and more

Ok so i thought i was boosted but boost gauge showed today i was only 2 psi so i turned the boost up to 10 drove with factory injectors and it seem to have a hesitation in the higher rpms so i tried installing the srt4 stage 0 injectors and right off the bat the car had a ruff start and bad idle for about a min then smooth out and i theow a code p0172 again.

Why is the bigger injectors haven a hard time working you would think they would push the fuel needed from the start. After that the next few start it would die out. What would be a good injectors to use on a 02.

You need the PCM tuned!
You will be able to run the bigger injectors once your pcm is tuned for them. The SAFC controller is not going to help pull enough fuel down low to get the motor to run correctly.
Depending on your local state laws for passing emission inspections, I would run either MS2 or get your stock PCM tuned properly with a tuner.

I think i got it im using stock injectors and it seems to drive fine pushing 10psi. I still need to get a wideband installed to make sure but test runs been good. I blow my first turbo pipe off lol 4th gear 5500rpms at 10 psi pushed the pipe right off the turbo. Scared me for a min thought i really did some damage to the motor lol
