So, after a dyno day and very disappointed results.
I felt the urge and the need to do this carbon clean as I am at 97k miles and have no idea if the previous owner ever did it.
First off, thanks to DRAKLORE and his awesome DIY's and explanation and the STaSiS k04 installation guide.
The results is phenominal, YOU MUST GET YOUR CARBON OUT OF YOUR ENGINE.
The throttle response is a HUGE difference, and my RPM seems to go up way faster.
Ignition now is so much smoother. It used to take 3-4 chokes before the car would start, it would take half a choke and the car started.
All in all, the car is WAY smoother and quicker.
Just a few heads up for those who want to do this.
1) Definitely do research, and have the guide ready. Look through multiple threads and learn the comments and etc. KNOW WHAT YOU'RE DEALING WITH
2) Have the right tools! Make sure you have the
-Triple Square M5 screw
-a magnetic pick up tool because nuts and screws will fall off
-air compressor (or just the compressed cans for keyboards - grab a shit ton of them) / or vacuum.
-seafoam and/or brakleen (or carb cleaner).
3) When you re-install the intake manifold after you finished cleaning your valves, you wanna make sure your BLUE o-rings are ON all four injectors otherwise you will have fuel leak, which means u gotta re-do the whole thing again.
4) BEFORE you start your car when you finished installing and double/triple/quadruple check everything to make sure the bolts and nuts are on tight, and all the sensors are plugged... Turn the ignition onto ON, and wait about 1-2 mins, then off, then ON. You should repeat this 3-5 times to let the fuel flow through the car and fill up the HPFP and the Intake Manifold/Fuel Injectors, otherwise your car won't start.
5) Be prepared for a long work job, this took me and my friend a loooooong time.
6) Valves will either be OPEN or CLOSED. Me and My friend used Seafoam for the OPEN valves, and Brakleen for CLOSED valves. The closed ones are so mcuh easier to clean cuz we filled up the cylinder with Brakleen, and let it sit for 5 mins, then scrubbed with our long flathead to get them loose off the valve, then dried it up with a shop rag, then used an Air Compressor and blew the poop out of the valve.
I think you can use Brakleen for the OPEN valves as well, but we were a little scared, so we used Seafoam.
You definitely need to get down and dirty with your flathead and scrub and try and dig them out as best as you can.
The job is all labor if you have the right tools already, and one or two cans of the cleaner, and air compressor or vacuum to suck out all the carbon stuff
