DIY-Injector replacement

[skandalis447]

Finally after many days thinking what to do with injector replacement on Friday i did replaced them...It was difficult to do and needed small hands...however,after approx.6 hours everything was done. 1)There is no need to lower the motor,not even an inch...i did everything with the motor in the original position. 2)Drivers side. First I removed the airbox and the intercooler hose...it can be removed from upper side if you first remove the airbox...no need to jack the car and go underneath... then I removed fuel filter,F hose(for more space)and the metal intake hose that goes from the airbox behind the engine,to the firewall...this hose has FOUR screws and a clamp...three of them are at its end,near the firewall and need a large extension on a 10mm wrench to be unbolted while the fourth one sits on the upper side,near the F hose...When hose is removed you can finally see the fuel rail...then I unscrewed fuel hose from the filter and second fuel hose that goes to the other side of the engine with 17mm and 19mm wrench.Then i unbolted two 10mm screws that keep the rail in place,reversed the rail upside down so to unplug the connections to injectors and took the rail out.Replaced stock injectors with RC 60lb,and reinstalled the rail line.the problem is that it seats 6mm higher and 5mm to the left than before because new injectors are larger...injectors are seated at 45degrees angle compared to fuel rail so the holes of the rail need to be enlarged for the screws to pass and bolt to intake...Photos will show exactly the difference...Also because now fuel rail seats higher needs spacers,and i used 2 nuts of 6mm hight...Everything was OK,rail was very stable without any leakage...I reinstalled everything in reverse order...except for the airbox... 3)Passenger side... With the airbox removed,remove engine only side of intercooler hose and air pump...air pump is easy,just 5 bolts,a hose and a plug...also I removed the vacuum solenoid bolted on airpump so to manage to get out of the engine bay the air pump!!Now fuel rail and FPR are seen...But you need to get rid of the harness that sits on the rail...Cut the tire wraps,and remove harness plastic base...then harness becomes flexible so unbolt fuel connections and two 10mm bolts that holds the rail on the intake...turn upside down the rail and remove the injectors there...the rail with the injectors in place is not possible to get out...with the injectors in hand take the rail out,replace the FPR,Enlarge the 2 holes of the 10mm bolts stated before and re position the rail below harness so to install new injectors...Install new injectors and bolt the rail on the intake...then reinstall harness base,clamps,tire wraps,conectors,air pump,intercooler hose and airbox...When airpump is reinstalled because fuel rail is higher now it might touch a metallic fuel line...I slightly lowered this line to avoid metal to metal contact... 4)Tomorrow I will add some photos...

from my understanding the RC injectors are much easyer to do then the regular 60 lb seiemens dekra with adapters.

You're very welcome, glad I could give back to the community, surprised you didnt have to lower the engine, I did to remove the Y pipe and give a little more room. I swapped the motor mounts as well.

Looks good! If you are doing the injectors, leave your stock 3.8bar FPR.

Yea its a bitch...you did it in pretty good time, the only thing I would do is also take off the Y-pipe it gives a little more room.Good job man, it's rewarding when you do it your self

Big thanks, great write up!

more pics, please

[skandalis447]

ok...got the pictures resized so to upload them...you can see the difference in the holes of the fuel rails...This enlargment is needed in order the rails to sit properly on their new position...

[skandalis447]

I replaced the FPR with a stock one because I had a 5bar...But with the injectors it is not needed...Hopefully tomorrow the car will be fine tuned so to see where we are about...
