Do you have pics of the manifold? Is it log style or tubular?

Tomorrow, the xA gets pushed to the limits, the fueling and clutch holding capability along with the turbo will be maxed out. C16 this time around, with strait h2o injection. Should make for an interesting evening on the dyno.

halfway through the tune, the pulls were becoming inconsistent and the boost wasnt inreasing. The turbo took a crap. On a good note, before the turbo gave it was odvious that the stiffer valvesprings helped a lot. The car was producing power all the way to 8000rpm :)

yes, most likely a gt3076 . I believe my car eats turbos because of the high boost I run. Also, I may get a high flowing blow off valve such as a turbosmart race port. I think perhaps the turbo encounters surge when I shift. While Im at it, Im going to verify the oil supply and measure the cc per minute.

I'm amazed that all the valve springs between all these motors are the same size

omg you are my boost role model. I think this was mentioned in another thread, I know you were running a stock motor except the rods. Is the valve springs the only thing you changed or did you upgrade the pistons also this round?

I imagine he had no choice but to get new pistons. He showed photos of the damage in his other thread titled "Finally, my motor went". Number 4 piston was damaged previously from a destroyed spark plug, and number 3 took some serious pounding when the valve dropped. Just wondering what piston set he went with and if there was any damage to number 3 rod.

Same bottom end, pistons and all. Just a replacement head decked and supertech valve springs. I was amazed that the motor pulls 20inhg vacumm after seeing my clyinder walls scored.

I found out today why my 6 month old turbo failed. The oil feed line restrictor had a peice of debris in it, which cut off oil flow tremendously. I did an oil change days after installing the head, but that was probably too late. Also, I have my oil feed line going to a oil filter sandwich adapter, which is pre filtered oil. So lesson learned, turbo oil supply should always come from the block.

Hey just an update... Im going to swing for a gt3076 this winter, but in the mean time I installed a $200 cheap turbo of similar dimension to my Garrett t3/4 50 trim which just failed. Im VERY AGAINST knock-off parts, but Im committed to attending a time attack this weekend. Im running 26psi (4psi less) because I don't want to go too hard on this turbo. Numbers are good , and notice that the car makes power all the way to 8000rpm! The supertech valve springs did wonders, those along with the hayabusa style turbo manifold allowed that to happen. Still stock head, valves, cams, intake manifold , throttle body.
