Noice.

Here's my drive line.

[Crunchy Taco [OP]]

Hopefully this weekend I'll get some good video of some turbo noise. I found a new driveline so I can wheel this weekend. Turns out the driveline from my wife's runner was the same length as my Tacoma with duals and a rear end moved forward go figure. That's how I got out of my little sitchy the other day and drove hers back to the house in front wheel drive. So anyway I picked up another 4 runner driveline and guna run it for awhile. It's a one piece with a double u joint up front so it should be smooth and strong.

I just found your thread!  Sounds like we have totally different issues with the turbo setips on factory ecu's.   

I ordered up the voltage clamp and it should be here Friday I hope because I want to go testing on Sunday.  Bought a multimeter to set the voltages and away I go

On a side note the guys @ G-fab and I built a teeter totter for our crawlers.  We are bringing it out in the woods (trail 47) on Sunday with the help of the forest service.  We built the whole swiveling mechanism out of steel and we are using logs for the rest.  I'll get some pics of the contraption on Sunday and post em in my thread.

Mine seems to be running fine.    I do not have a blow off valve. I'm running just over 8 psi... pink injectors. Walbro 255 fp,  4 coil motor, my maf is 12" away from the turbo. No egr, exhaust gasses don't burn very well    cat is back on. Still runs fine but ran way better without it. night and day actually. Vss is not hooked up, hmm what else...

What size tubing and how many inches of charge pipe do you have on your turbo setup?

Maybe me and the wife will come out Sunday for a couple hrs. What time you guys Meetin up Sunday morning. An also ill have to measure all my piping when I get to pville tonight. I can tell you right now that my maf is right in front of the turbo though, reason being is it didn't seam to make a difference when I had it far away so I just put it back where it fit the best. You'll see my setup this weekend hopefully:)

It's about time you found my thread!

[Tungsten Slayer]

I know, I should have seen your thread ages ago.  We are meeting at potato hill 9 AM Sunday for the big install of the teeter totter.

And I was asking Nation about his intake since he has no issues.. except with the 5-O..

[Crunchy Taco [OP]]

Yea I kinda figured out that you were talkin to nation. We weren't able to make it out to the trail I was up til 2 pullin turbos out of an Audi a6 that was my plan this weekend to get that car torn down I figured it would get in the way of having any fun. Now driving back to Portland today. Can't wait til I move to central Oregon full time, gettin pretty close to doing just that.

[Crunchy Taco [OP]]

I've been a pretty hardcore mechanic for about 15 years now and this was by far the hardest job I've ever done. Dropping the motor out the bottom of a 2001 Audi a6 Quattro to get the twin turbos out.

[Crunchy Taco [OP]]

I think I did pretty good compared to my brother in law that did the same thing on this car ten years ago in the shop at Audi of bend with a lift, an adjustable table to set the motor on and two of his coworkers that work on audis for a living  in half the time it took me alone in a home garage with some wood and some jacks. I guess he said they did it in like 8 hrs and tear down and reassemble is guna run me about 16 when it's all said and done. One 8 hr day to tear down an 8 hr day to button her back up

[Crunchy Taco [OP]]

Plus I have to rebuild both turbos. Guna be a long job all together

[Nation]

Don't ypu love German engineering?

[Crunchy Taco [OP]]

It's definitely some of the hardest and trickiest stuff to work on. I like Japanese engineering it's more better

[twistedtoy92]

LOL! Oh yes, gotta love these damn euro's! I get to pull my tranny, clutch and dual mass flywheel tomorrow after work and install new clutch, slave, ss line, throwout, and single mass flywheel then drive back home...

[Crunchy Taco [OP]]

Sounds pretty close to how much work I just had to do. I'm trying to keep that a6 running good cause someday the inlaws are guna give it to my wife and I. Figured I might as well figure out how to tear it all apart, it will prob need turbos rebuilt in another ten years. Car is so fun to drive its super smooth and for being bone stock with k03s it gets pretty nasty

[twistedtoy92]

Thats got the K03's in it right? Thats what I pulled off mine, things are so tiny but spool like crazy!

[Crunchy Taco [OP]]

Yea ko3s. I was already pretty impressed with it when it was runnin good. Even when you shut the car down from idle you can hear it spool down, I guess it dosnt take much to get those babies turnin

[twistedtoy92]

I was hitting 22 PSI at 2300 RPM with my k03... but boost fell off hard after 5200 RPM

[Crunchy Taco [OP]]

Is it because the little turbos get hot when you push them too hard ?

[Crunchy Taco [OP]]

I tore the ko3s down and there's a lot of damage. By the time I replace compressor wheels, rebuild kits, and the little plates that go behind the exhaust turbine I'll be in it deep enough. I been lookin at some ko4s as an upgrade, there's a pair for 550 I'd like to buy but I wana kno if the factory tune will adjust for it. Are you familiar with the ko4 twisted, not much difference, just able to push more boost and hp or ? Can I slap them on and expect any benefit without messing with the factory tune?

[Crunchy Taco [OP]]

They will prob. Run the same just stay a bit cooler than the ko3. I don't wana mess with the factory tune but I thought maybe there would be a small benefit somewhere with the ko4s. Keep in mind I'm mainly wanting to go with 04s cause the price is right

[Crunchy Taco [OP]]

Picked up a walbro 255 fuel pump and also wanted to try out the lce fuel press.  gauge. I wana check my pressure with my pump I have now cause I think it's lacking flow as I had the same prob a few years ago. The Tacoma fuel pumps have been known to lose their flow but continue to work. It's very strange, about 4 years ago I had problems with my truck starting, especially when warm, I checked everything and finally tested my fuel press. It was 15-20psi. I'm surprised it would run as much as it did. Anyway I think I'm havin the problem again it's been takin a minute to start even way before I turboed. It always starts on the second try, after it worked sone press up. Plus with the lce gauge I wana monitor after I put the 255 on and bigger injectors, wich is next on my list!

[Crunchy Taco [OP]]

I'm lookin to buy 300cc injectors from lce. They're 75 bones a piece and are good for up to 220hp. My latest plan is 10psi, walbro 255 fuel pump, 300cc injectors, aem FIC piggyback, and some kind of adjustable fpr. I'm guna call it good there with head studs and a good head gasket on stock internals. I wana keep it reliable for my dd plus have v8 power haha. It already smokes everyone up all the long hill on the way to central Oregon. I pull 80 in 4th up an hill since I intercooled it and it's much happier. This is only 5 psi. Can't wait for 10

[Nation]

Go bigger than 300 cc heck, I think the supra fuel injectors are 450cc. 

[Nation]

What's your fuel economy like after the turbo?

[88_Pathy]

I wanna turbo my 3rz so bad. Just worried about fueling. So, from what I have read 5psi can be done without mods? Or am I off?

[Crunchy Taco [OP]]

I have a maf calibrator cause I needed to ad more fuel from 2psi and up but other guys are runnin 5 psi with no problems. I think it depends on the manifold, turbo, wastegate, your runnin. I built my mani and am runnin an internal wastegate t3 turbo. Nations 3rz swap turbo build in projects and research is runnin like 7 psi with the lc engineering kit and stock computer and says he's runnin good. I was never really able to get mine runnin right with the stock computer and even now with the maf calibrator I am lean at 3-5psi but I think I might have a faulty fuel pump. Plus I feel like I need a tuner that adjust timing as well. I will update when I put my bigger fuel pump and injectors in and tune that setup with my maf cal.
