We Can Rebuild It!
By Frank Ewald
It was the last day of the Ontario Time Attack season and the competition was at the Shannonville Motorsport Park's Long track. We'd been up the night before adjusting the timing and finally getting the car to perform, as evidenced by the fact that Katie had just caught and passed a Corvette. Then she pulled off to the side and parked. No noise. No smoke. It was just a graceful glide to a stop. The corner marshal, who helped hook up the towrope, said there wasn't anything unusual. Katie, who knows the car almost as well as I do, indicated the power just stopped. The car was towed off the track to our paddock and we started looking for the culprit. With the oil cap off the stationary camshaft told us that our engine had suffered a catastrophic failure and, with that glide to a stop, our ignominious season had come to an end.
|My daughter, Katie, and myself have had an ongoing challenge to see who is the fastest. In the first year (2009) we jointly participated in competition, I shared that she was the better driver but I still had the edge on speed. I've been playing catch-up ever since!|
It wasn't for a lack of trying, but our Nissan NX1600 with its recently transplanted Pulsar GTi-R drivetrain had simply not met our expectations. It was amazing when it hooked up, but perhaps the learning curve for running a turbo'd B13 was too steep and I wasn't learning enough about the new setup as quickly as I needed to in order to be effective. The highs were keeping up with Corvette Z06's on the straights (well, that may have been because the wastegate hose was not connected properly and we were pumping out unlimited boost) to the lows of being towed off of the track with an issue of one type or another. Our erratic 2011 season was plagued by boost issues, overheating, handling challenges and human error that just made us want to pack up and go home. Three weeks earlier at Mosport human error led to an over-rev situation that resulted in a broken rocker and mangled intake camshaft. We finished that event borrowing Jeff Daley's NX2000 race car. Two weeks later, after a quick top end build, we thought we were ready to go but lady luck was not anywhere near us. We ended our season with a DNF and a lot of experience gained. Tear down showed that the Shannonville incident barely even nicked the camshaft, while the timing chain now had a beginning and an end. It was a gamble to assume that the chain hadn't been affected in the first incident at Mosport; history proved that it was not a gamble we should have taken. The four hour drive home from the race track seemed longer than usual. It was very quiet too.

A sane person would likely have switched platforms at this juncture in time. In my professional role as an elementary school administrator I am usually recognized by my ability to make logical conclusions about situations. This, however, is quite different. If you've read earlier articles about this Nissan NX1600 you will have observed that there is a strong attachment to this car that I have owned for twenty years. It was not a question of switching platforms for the track (I do have a marvelous Mazda RX8 that would be a wonderful track toy) but how to go about with the rebuild. I have wanted the GTi-R drivetrain for over ten years and I was not ready to give up yet. After a few weeks of discussion with my very good friend and trusted mechanic, Dave Schlueter, we decided to start the rebuild in my single car garage. This would not tie up his shop space and would be close to home for late night and weekend work. That also worked for Dave, as he lives only five minutes drive away.
