I finally got around to installing my ARD 19T conversion wheel and compressor cover, 4.4 ECU, TCV and new WGA. Install went very good in fact it was pretty easy going. I can say for sure that the car seems to have lost a bit of the low end punch. However when the boost starts to build above 5psi it moves out with authority compared to the 16T. The conversion wheel really does limit the amount of low end boost and onset of it. I'll get use to it I suppose but I may play with the wastegate a bit to see if I can bring it on just a little faster to try and recoup a bit of the low end punch. Over all I'm happy with the ARD parts and I knew that bottom end was going to be sacrificed for mid and top end performance, I just wasn't sure how much and now I know. I just throw this out there now so far ARD customer service has been great. Over all the car pulls harder and feels faster bottom line, except right off the line. So my luck also played a hand on me and no good deed goes unpunished. My rear main seal decided to go really bad yesterday. Leaks something fierce. Best I can figure is I have some new found crankcase pressure due to the higher boost levels and the old RMS gave up the ghost. I did a PCV service couple months ago and the old stuff was pretty plugged up and the car did drip a bit before the service but seemed to stop after it. Perhaps that played a role in the most recent failure. This weekend I'll start the transmission removal. Got to love these old cars and their new problems.....
