2ZR Turbo Yaris

[06YarisRS]

A Slow Weekend...

Didn't get much done due to being away visiting family. A couple things project-related did happen though.

I fixed an issue I had with the oil return line. It had a very, very slight uphill curve going into the oil pan. I reclocked the center section of the turbo, cut 1/2" off the pipe and reinstalled. The front of the car is higher on the jackstands than the back, so once the car is lowered, I should have a very good downhill run to the pan. However, I'm going to temporarily replace the steel braided hose with clear braided hose of the precise length and test the oil drain with the car still nose-high. I imagine I'll be in boost on a few long hills from time to time. As a positive spinnoff of clocking the center section of the turbo, my coolant lines are now a wee bit father away from the downpipe. I have about 1.5" - 2" clearance. I'll wrap those in the aluminum tape that came with the kit. I should be fine heatwise as I've read online about people with lines closer to the downpipe who have had no issues.

I also addressed the clearance issue between the first charge pipe and the subframe. This I did by shortening both legs of the coupler, allowing the aluminum pipe to go up farther into the engine bay. Although I've read the install manual myriad times, somehow I missed the trimming of the 45 coupler (RTFM, more carefully, silly boy, lol). I now have about 1/2" clearance where before I had slightly less than 1/4". Since I still haven't tightened up my dogbone mount, I rocked the engine back and forth and the piping doesn't contact the subframe. Yay! I had a few inches of turbo to wastegate hose left (after clocking the turbo way back when, I had to shorten this hose) and it worked perfectly as a contact pad between the charge pipe and engine casting rib. I degreased the rib and hose and glued it on with a bit of RTV. Worked great! I'm going to use a bunch of this around the car for all potential contact areas between the turbo piping and body/frame etc.



In other news, most of the stuff for my custom intake has arrived to my US destination. I hope to start to work on that about mid week. I may get the urge to hook up the stock airbox and start the car, but I'll try to wait until my intake is finished.

Lastly, I'm going to ask the turbokits guys if I can get a shorter oil feed line. The one with the kit is quite long. I need one less than 1/2 the length of what came with the kit. There's probably a lot more space in the Corolla to route that around than there is in the Yaris.
