I am rebuilding my motor tomarrow with stronger internals and what not. I have a few questions that I need answered real quick before I can do it though.

1) What are the torque specs for crower rods? (D-series motor)
2) Arias pistons- valve reliefs are deeper on one side of the piston....which set of
valve reliefs are for the intake and exhaust??
3) how do I know when the rings have sealed??
4) I heard someone mention priming the turbo with oil the first time it is installed...
how do I do this?

I know this is a lot but you guys always have answers

One last thing. How bad would it be to install my turbo at the same time as I am doing my rebuild? As long as I let the motor break in properly before hitting heavy boost I should be alright, correct??

1) Don't know. Call Crower.
2) Intake side gets the deeper valve reliefs.
3) After 500 miles of break-in driving, your rings will be totally mated to the cylinder walls crosshatch as they'll ever be. For the first 1-200 miles, keep the revs differentiating... up and down as much as possible, below 4500rpm.
4) Run the oil line into the turbo, leave the return line disconnected into a drip pan... remove ECU fuse so the car will not start. Turn it over until oil has cycled thru the turbo and has returned into the drip pan. Reconnect return to oil pan and put ECU fuse back in, you're primed.
5) I personally would break in a motor without the kit on simply because I wouldn't be able to resist punching it which is not good for the motor in it's first few hundred miles. If you can resist, then being gentle with the kit ON will be just fine for break in.

thanx for the help. I will call crower on those torque specs.
