420A Bolt-on TechIntake, exhaust, ignition, fuel system, cooling, etc - specific to 2G N/T DSMs. New Members must limit their 420A tech posts to this forum.
I asked Hahns which side was which and they said the top one is the "outlet" and the bottom one is the "inlet".
I also ditched the whole bumper saftey support, so all that cover my intercooler is the bumper itself.
Edit: I think I realized you were talking about something different. No I havent cut that peiece off, I plan too, but my main concern is that I get the car running with no leaks, and that it builds boost okay. Then I will tinker with the minor things, such as this peiece of the bumper.
One other question, referring to the FCD. The Symtech lab instructions refer to black, yellow green and yellow black, wires. I have green black, yellow green, and yellow black wires.
Im planning on just referring to the green black one as the black one, because that is the only one that doesnt match up.
Maybe you guys can tell me something I dont know.
Okay guys well its altogether, and I start it up today.
Having some issues, and didnt get too much trouble shooting time, so just looking for some input from you guys.
Some things you should know about...
It will not idle by itself, if you take your foot off the gas it dies. That simple. It sounds like its missing, when you bring it up to higher rmps it stops, bring it down a little it does for a minute then stops agian, and so on. But you pretty much have to keep it above 1200rpms.
1. I have no exhaust lol. I want to get it to idle good before I take it to the exhaust shop.
2. That means no 02 sensors at all
3. Around 75psi of oil pressure
4. When its missing the fuel pressure is jumping from 25psi to 35psi like crazy. When it stops missing then it evens out at 30psi. This is on 315cc injectors and a sfmu. (The sfmu isnt set at all) Im still not totally sure how to, will look into it 2morrow, but it still should be able to idle at 30psi of pressure...(By the way, the sfmu has a screw in the boost port and a vac line hooked up to the barb fitting at the top, thats it)
5. The boost gauge isnt working... at all it doesnt move from 0psi..
6. We revved it up all the way to 4k I would say.. then it backfired. The wastegate never opened, or at least I never heard it nor saw it.
7. The bov never realsed any pressure, but the throttle plate never got closed all the way either, so that could be why for that.
8. The timing should be good. Set it up according to Chiltons and everything lined up.
9. The plugs look fine
And... hmm idk just look at the video and let me know what you guys think.
O I also unhooked the turbo from the intake and it still ran like that so it isnt really related to the turbo.
Throwing Code P0106 for map sensor/barometic sensor, and some other crap. Perhaps we screwed up with the FCD install?
Idk just looking for some input.
Thanks guys here it is, and thats my dad at the end, hes kind of excited lol. Apparently he likes how it sounds other then the missing. Like a "racecar" he said lol.

-Without your O2 sensor hooked up your going to have a littlle trouble keeping it alive without throwing codes.
-Boost gague will not show boost from just free revs... The BOV will not release pressure because there is no boost...
- You should get that downpipe together first.....
Maybe someone can chime in dealing with the fuel pressure and the S-FMU, because I have never used one. Congrats on getting her running!
It should still run with no 02 sensors. When your 02 goes bad your car still runs, I know I just had to fix one on another car lol.
Hmm, boost gauge doesnt show anything with just revving? There is boost though.. I just dont understand how it cant show it.
I understand why the bov wouldnt do anything because the throttle isnt closing, but it is building boost. I know because I took the coupler off, and it was definatley blowing air..
This is my first turbo experience so maybe Im missing something..
Edit: I do have a wideband, just nothing to put it into yet... unless I can stick the tip of it by the turbine outlet lol.
Yes, the ECU will remain in open-loop without an o2 sensor.
The boost gauge should register vacuum, as well as boost. If it's not moving at all, then you either have a massive vacuum leak, or the gauge is installed incorrectly.

There is very minimal boost when just revving an engine, so your gauge will not go above zero(especially if you are boosting low, but as Locke said there should at least be vacuum (unless your revving too high to tell).
Where did you tap for your boost gauge source?
Thats what I was meaning, it wasnt showing vacumm or moving from 0psi at all. The vac line runs from the compressor to the mbc (the boost gauge is after the mbc) then to the wastegate.
It should probably be in the intake manifold and thats what causing that problem.
After work today I will check for vacumm leaks, retap that boost gauge, and try to bring down the fuel pressure on the sfmu and see how that works.
I am considering just getting that downpipe made that way I have the wideband and it makes things alot easier...
No leaks as of yet. But only time will tell.
Thanks for your input Locke and TalonESIT, very appreciated.
Edit: Would having it running rich, still cause it not to idle at all? Or is the idle problem probably related to a vacumm problem and the misfiring is related to the running rich?

Reason: Another thing
Mike, thats probably what I will end up doing, if I cant get it to idle right today. With the wideband it should be really easy to tell whats going on, plus then another problem is removed.

congratz on getting it fired up. running too rich could overflood the engine cause it to choke and die? when you hooked up your fcd, you set it as 3.63 right? (its around that cant fully remember) i think you should get your sfmu set correctly.

Honestly this is what happened yesterday. I got the battery installed and a few wires run, the fcd hooked up and it was 9:30 when I started it the first time. Looked for oil/fuel leaks but thats about it. I had work at 7 today so I didnt want to be up all night.
I just wanted some input from you guys so I would have some things to check into right away.
So, Im going to check vac lines, sfmu/all fuel issue possiblities, the fcd, retap the boost gauge.
Anything I should check? Besides bringing it to the shop and getting the downpipe made.
So after looking it over tonight and rechecking the ecu codes, I have determined that somehow the timing is off a tooth. Somehow during the process of putting the belt on it must have slipped a tooth... I dont know but its definatley missing bad. I removed the FCD and got it to idle, but it still misses. Time to tear back down..... *sucks*

Are you sure? Because something like a slipped tooth could cause internal engine damage...
Its definatley not more then one tooth. When the piston is at tdc the cams arnt lined up perfectly where they should be.
We turned the crank before we started it to be sure that everything was going smooth and it was, so no valves hitting pistons or anything.
But I do think thats whats causing the miss. Only other really explainable thing, we got the sfmu down to 28psi, probably running rich but not bad enough to make it miss.
So tear down time on friday.
Suppose to turn the engine over about 6 times by hand to make sure the timing is still all together. Follow Corbin's writeup to time the car, I did and never had any problems and it was my first time doing a timing belt job.
