Was wondering though - how much is the custom work (such as piping) costing you? Or is your buddy doing it free of charge?

Its all me except for welding up the downpipe and mabe some final tuning. I am going to try some tuning myself first. Gotta learn somewhere!

Power to ya man. I'm hoping between the two of us we'll help shed some (additional) light on turboing this car successfully. I can't even begin to tell you how much I get laughed at when I tell people what I'm doing to a YARIS.

Granted, those are the naysayers that think a turbo on this car is only going to put out 10 hp at .5 bar.

I kinda wanna learn tuning too, but that's one thing I just don't feel comfortable doing currently. The other way I see it is that an AEM wideband is easily $200, and with that money you're already half way done covering your tuning costs.

Once again, good luck to you.

Well this thread has been quite entertaining. You have one more fan rooting for your success can't wait to see.

What I love the most is the budget. Really goes against the idea that turboing successfully will cost $5000.

Budget turbo on a budget car makes total sense.

Alright, I finally got some more work done today. first since last post I took the exhaust manafold to my friends machine shop and had him resurface the part that meets the engine block. I think it would have been ok it just looked a little rough. I also installed the turbo and manifold for the third time to set up oil feed and drain lines. This is my daily driver exect for my motorcycle, so until I am fully ready to go I need to keep retuning to stock when Im done working.
It was hotter then hell today and super humid. I removed my lower oil pan and tryed to judge where to tap the upper oil pan for my return line. I had allready recieved my 20in braided -8an return line and one 45 degree 1/2 npt fitting and one 90 degree npt fitting to install in the upper pan. After checking this out I decided 1/2 in is to large a hole to be drilling and tapping into my engine. So I will order a 90 deg. 1/4" to -8an fitting. I didnt want to wait for that to get here so for now I bought some fitting from hardware store to use 1/4" rubber hose. I also bought a 1/4" npt tap. I drilled a hole in about the only place accessable in the upper pan without removing the engine. I used my unibit a drilled to 7/16 as recomended by my tap. I was very surprised at how thin this aluminum is. I then tapped the hole. All worked out well. Also installed fittings and gasket with some silicone on the turbo.
One problem I have is that with the return line so low on the pan. If the line is removed oil will leak out. Im sure atleast 2qt. So for now I installed a kinked hose to seal my engine.
Tomarrow I will prime the turbo. Attach the return line, and let it idle for a while when checking for leaks. Im sure it will be loud as hell with no exhaust.
Speaking of that I found a local exhaust shop that will work with me on welding up my downpipe. I told then I will need to take it home between welds and measure and mark for the next weld. All for 40$. What A great deal. Hope it all works out.
I will also order my AEM FIC tomarrow after depositing my paycheck.

Nice work man but why did you tap the block so near to the bottom?

[cali yaris]

^ might be ok, but it also might back up, I had one do that. Regardless, he's committed to that spot for now.

Regardless, he's committed to that spot for now.

LOL you got that right!. I mean you could always plug or have it welded, but it should be alright. It will drain out when all the oil gets moving away from the oil pan and starts to circulate. Ever test how much oil is in the pan when the car is warmed up? I think you should be fine

[Focus_Sh1ft]

Bah, I wish I had a mechanic friend and all the tools you have lol.

The return should be fine, it's even lower on the Zage pan. I haven't (yet) had any problems with it.

[cdydjded]

The return has to be above the oil line. You have it too low. You will know it is to low when you get white smoke from you exhaust....

[pimp my yaris]

Well I primed the turbo and started her up. Sounds awsome when spooling up. No intake tubing in place yet. Also no oil leaks and sending unit working well. I think my return should work well as long as long as crankcase is vented properly. As for why its so low. Its very tight behind the engine and I drilled about the only place I could fit my drill between engine and K-frame. I will by a catch can soon to keep crackcase pressure low and keep return line free flowing. I also got a short video http://www.youtube.com/watch?v=G07Q5LSiT6I

sounds like it was blowing bubbles

[pimp my yaris]

Ya I think my I-phone was maxed out. And it sounded a little weird with no exhaust. Gonna try to get exhaust completed this weekend.

[Focus_Sh1ft]

That sounds... So familiar...

[Parmas]

Man that is so familiar when I had it with only the downpipe attached

At least I enjoyed it for a few months like that then I had to make a full exhaust because of people complaining in the neighbourhood

[pimp my yaris]

Ok more work today and a problem. I installed all my intercooler piping, air filter and mass air.
Tryed to start her and it will only run for about 10sec, then it starts missing and shaking then dies. Of coarse check engine light is on but my obd2 scanner will not read newer car that use CAN communication system. Also my o2 sesnor is disconnected because I do not have downpipe yet.

What Im thinking is that the mass air sensor is to far away from the engine to read correctly. Mass air is located on intake side of turbo. So many feet of tubing including intercooler and turbo between mass air and throttle body. I may try to have pressurized mass air and locate it just in front of throttle body. More similar to stock location so there is not such a lag in readings.

Hey Jerzy if your checking this please tell me where zage locates there mass air sensor. I am very curious. And any other sugestions are appriciated.

[pimp my yaris]

Never mind I'm a total retard! Dam mass air was in backwards. Air flowing wrong direction. Its all good now.

Still have no downpipe, but I coudnt wait no more. I went down the street and gave her just a little gas and got up to 3psi. Awsome the torque started pulling right away. Thats enough for today. Tomarrow hopfully I can complete downpipe or mabe the whole exhaust.
