[VIDEO] S5 Turbo JDM swap, very low rough idle, no power
Hey guys so I finally finished my turbo swap, the engine has good compression, I have good spark, checked all my vacuum lines, and I am stumped at why this thing doesn't want to run correctly. Also I put some fuel injector cleaner in with the fuel to make sure that's not a problem but that hasn't helped much yet. I am running out of things to check for so I'm hoping somebody can tell by this video what might be causing the problem. The reason the engine sounds loud is because I'm running on only a 3" downpipe right now. Help me get this thing back on the road!

also, this time that I started it was the first time that it actually held an idle. before this time (the engine wasn't warmed up) I had to give it some gas to keep the engine running and when the throttle was closed it would die, but as you can see it now idles just super low and rough as freak as you can tell by the engine shakeage.
oh yeah and I test drove it around the block. i have a twin plate orc clutch, and the engine barely had enough power to transfer the weight to it... once i actually got it in gear, it had very little power.

Where is there good info on stand alone? I know next to nothing about wiring/ecu stuff so I'm learning as I do this haha. I'll start searching now too and check it out. I'd like to get the car running by this weekend and have all day tomorrow and Tuesday to work on it so whatever would be best. This is currently a daily/drift car but will eventually be strictly a drift car

lol well let's not get on that topic right now i'm worried about getting it started 
but basically i will drive it on the street until it's too modded to.
i think i'm going to try and get my hands on an n370 and s5 na harness that seems like the easiest and quickest route right now unless anyone wants to convince me otherwise. i'll update this with the results. thanks for all the advice!

Sorry to say it but it may be blown pull spark plugs and get a little mirror and check through the spark plug holes and turn the crank pully by hand. I blew my S5 swap from lack of FCD! and that was what happen to mine runnin on one rotor!!! Or check if both coils are firing...

Well I checked compression before the motor was installed and it was good both rotors were good. So unless I blew one starting it or something. I haven't revd it past 3k since it's been installed so I doubt it's blown but i know it's a possibility

This was mine after it blew the apex seal on the front rotor. So also check if injectors or good get them cleaned if all apex seals are in-tact and your compression is good.
