You have to understand, I push the car really really hard. With my original Stillen setup, I would have seen 280f in these conditions I am 100% sure... Also, remember that Nissan has said that 240 is within the sweet spot of engine oil operating temperatures for this car. Most of my time on the track was 180-220f... 240f was peak. I am going to give this kit my strongest endorsement. This is the kit to get! Robert will soon be providing details. He sent me pics but asked me to hold off until we tested it at the track.... hang tight just a bit

SO, HERE'S THE UPDATE... My post yesterday was after my second track session... During third session, I had an epic battle with a Lotus, then the engine completely shut down on me after going into what I thought was limp mode. I had to coast off the track.... It was not limp mode. One of the O2 sensors on headers had become disconnected and very likely caused the engine shut down. I drove the car to my in-laws after the event. Looked all around the car and when I looked underneath I saw that my O2 sensors that attach to headers had been nearly sheared off the location they mount to on transmission. The bolt had either rattled loose or was sheared when the car bottomed out on my 9 hour drive to Utah from AZ. I'm not surprised, I did some very serious canyon driving. I reattached the sensors with some make-shift parts and drove home from UT to AZ last night. Got a ticket on 93, but that's another story...

Lesson learned... All of us that lower the car need to consider relocating the o2 sensor bracket from the bottom of transmission to sides.

Unfortunately, I had to cut my day short and missed the last 2 runs and the time trials at day's end.... But I should be able to post the video from session 3... Stand by

PS Mike, your buddy Jimbo (with MR2) says 'hi'
