Another one down! IS20 and USP catted downpipe are now installed! Thanks again MeltedSolid for this awesome guide. I used the exact same method, except for minor details here and there. I haven't opened her up past half throttle yet as I have just been driving around getting the coolant settled and making sure I don't have any leaks. So far, so good! Now I have to get the JB4 dialed in to see how that works. A tune is going to be tempting to get better fueling if I hit the ceiling sooner than I would like.
- I did everything on 10" race ramps. Didn't jack up the back, although I was tempted when I started. Wasn't necessary. Like you said, the wheels stayed on the whole time. I used my old rhino ramps as a 7" step to work on since the car is kind of high.
- Like you said, the biggest pains were the oil return line on the back of the block and coolant line on the back of the turbo.
- The oil return line was a tad stubborn coming out of the block, just like you said. I got under the mounting bracket with a screwdriver and didn't have much trouble getting it to come out. Putting it back in was more of a pain for me though. I had to use a medium flathead screwdriver to pry down on the bracket so I could thread in the bolt properly. For a junior mechanic, they might be tempted to force the screw in. Don't do it. Take your time. This would be a costly mistake if you stripped the threads on the back of the block and didn't have a way to fix it.
- For the rear turbo coolant line, I could easily get to the torx T30 bolt using my mini 1/4" bit driver ratchet (good). However, my only 8mm triple square bit was way too long (about 3") to operate within the close quarters of the firewall (bad!) What to do...I looked online and couldn't find a shorter one at any local auto parts stores around here. Everybody had the same damn long ones. Why?!! Also struck out at Harbor Freight and Menards..."What is a triple square?" they asked. So, I went to Napa and an awesome dude there helped me cut a long 8mm triple square bit they sold using a power table saw in the back room. We cut it down to about 3/4" and filed it smooth. I then used my vice grips to hold it perpendicular to the vice jaws to get that sucker out!. Out the door for $9 and now I have a long and a short 8mm triple square bit, and a story to tell haha!
- I damaged one coolant hose whilst removing the IS12 and have a temporary solution in place. OEM part is on order.
No whiskey ended up being required my friend! And, no humans or pets were injured (well, my hands and arms have a few cuts and scratches).
Can you share your JB4 settings? I am most interested to see your initial settings where you dynoed and then also your current settings. Please also include your Fuel Open Loop setting and Fuel Bias settings if you have any of those set below 100. I am going to start slow and will likely also be contacting George for advice as I go along.
I don't believe it!
LOL...a reputable tuning shop well respected and known to the VW crowd can probably do them in their sleep, and they quoted me 4.8 hrs. It probably took me about 8-10 hrs including setup/cleanup.
What tuning solution are you using?
