I connected two grounds to the cylinder head and the neg. batt cable to the trans. I will double check them tomarrow and clean them. Thanks for good idea.

Those two grounds on the driver's side create quite the symptoms if not attached properly...I can attest to that!

Double/triple check your marks on your cam gears and make sure you have the correct marks and all your lobes are pointing in the correct position in TDC. There was no damage to the 2az motor because of this. Just something to check also. You never know. good luck

I will check the cam timing again. The grounds are all good. I even attached a jumper cable from neg. battery to engine block. No luck yet. I feel im getting closer though. Thanks for tips everyone.

Well I got it started after correcting exhaust cam timing that was off 90 degrees. Took it for a drive after burping coolant bubbles. It sounded like I have marbles in my engine at idle and I had a knocking noise under load. I did this test drive without the turbo and mass air and air filter attached directly to the T-body. I thought for sure I had some major piston slap going on under load causing the knocking.
I just about threw in the towl on this motor. I was still fucking around at 9:30 last night and decided to hook up the turbo just for kicks. Mabe take it out with a bang! I was blown away when the knocking noise went away. I am certain now it was internal engine noise coming through the air filter. I still have the marbles noise at idle but I believe it may be a valve clearance problem. I hope. I will check it out and let you all know. This has been a very stressfull weekend. |

This is a very nice thread. Hope your car is running well.
Are you planning to run beyond the normal rev limit? Any plans to change to the yaris cup valve springs,since you may have to check the valve clearance anyways? Also what break in procedure are you following? |

Yes, I am wondering about valve spring bucket placement. I will check this out in the next day or two. I needed a day to break and destress. Just out of curiosity does your engine have some piston rattle at idle? I know its sleeved but I am sure U are still running forged pistons.

Don't go easy on the engine Brian. Higher cylinder pressures will push the rings out against against the cylinder wall which will make them seat better.

Mine is sleeved and I have some noise.
Our break-in included 5 or 10 minutes at 2000 rpm, change the oil, I think two rounds of that at different rpm's, before driving.

Ok, I checked all valves and they are all within toyota spec. And VW TDI is the pefect way to describe the noise at idle. A older VW from the 90's, not one of those new ones that are so quite.
They should tell you this in the instructions for the pistons so you don't loose your mind when you start it. Took it for a drive again and got on her a little. No problems so far. I can feel I lost a little torque with the lower compression pistons. I will make it up later once some fuel upgrades are done and I can crank up the boost a little. I am so happy to have a car again. And the clutchmasters clutch is much more streetable then my 6 puck ceramic clutch I was using. Although pedal pressure is much higher with this new clutch. |

http://www.scionlife.com/forums/showthread.php?t=215013 some more photos of a clean setup I just did on a friends xB (for future ideas). Made 156whp at 4psi on our dyno, pretty darn awesome ( about 171 dynojet). It still has factory cat!

That sounds pretty amazing. Is there a lot of turbo lag? What other mods are on it? 4psi for 156 just sounds high for what we see here, is the xB plumbing bigger stock?

Did some retuning today. Engine is running great. It is running a little rich with the lower compression pistons.
