rod bolts?
I have installed the Tuner Toys d16 rod and have already ran it for 2000 miles. I torque down the rod bolts to 37ft/lbs (Stated on TT website). I occasionally redline it a couple of time to see if the motor holds up and its still running strong. I am in the process of installing a turbo and was wondering if I should retorque them the correct way (loosen-tighten method or stretch gauge)? will it still hold up under boost if I left it alone? and if not, are the bolts still good for me to retorque them?

thats the thing, I didn't do it right. the right way is to use a stretch gauge and I only torque it down once to the specs provided but torque wrenches can be inaccurate. The problem is that its been running strong (unboosted) and I don't know if its ok to leave it like that when boosting.

A turbo is not going to add much additional stress to the rod bolts anyway. If a rod bolt is going to fail, it's going to fail at TDC on the exhaust stroke when there isn't any pressure in the cylinder anyway. If anything backpressure at high rpm due to the turbo will decrease the tension on the rod bolts at TDC on the exhaust stroke.
That said, the most accurate way to pre-tension (this is what you are doing when you 'torque' a bolt) a rod bolt is with a stretch gauge.

^^^ so does that mean that if it already last, it should be ok boosted. I didn't realize about the stretch gauge method until after i install the rods. should I do anything to them now?
