Damn....wow

Awesome work. Loving the build photos...

...still can't figure out why you started with a 370Z, let alone a brand new one, but hey...:tup:

Cause it aint trickin' if you got it!

Okay, I'll bite... could have bought someone's used race car and that would have been cheaper but I would not have been able to enjoy seeing the car come together one piece at a time... In addition, most come with lots of unknowns and mechanical issues that need to be sorted out, and you may get a car with a bent frame etc. And wouldn't have been *that* much less expensive, assuming I targeted the same level of performance... I could have bought an American muscle car but I don't like the way they drive. I have 4 full days in a 2008 corvette at bondurant, and I was not impressed - just not for me. I could have bought another Porsche, was originally planning on a 2003-4 996 C2 conversion but that would have been boring! Those cars are everywhere and it would never have been as 'good' as the many GT3 / cup cars. The Z has the element of surprise at the track - no one knows what times it will turn - in fact I find that a lot of ppl underestimate it... My total build cost is less than if I had started with a used Porsche... and less than if I had bought a new factory Ford Mustang racecar... and I'm confident I have a faster, more reliable, safer track car

Re why new... how many used 370Z's were available in Feb 2009?

The cost of operation of this car is low as well... I can pick up a rear diff for about $1k... can't say that about a porsche!!!

Well said Travis :tup:

Just a heads up; I took my car to Willow last Friday and had all kinds of issues. Hard starting, getting codes not getting codes, car wouldn't accelerate over 3500 rpm, would die while idling and all with a full tank of gas. Didn't even get on the track.

We took it in to Fontana Nissan and it turns out that the crank shaft position sensor overheated and melted the sensor. I have a new one coming under warranty. I'll have them protect it with a heat shield of some kind.

Anyway Travis, you guys might want to take a look see at yours and protect it with some kind of heat shield or tape.

Fontana Nissan ROCKS! Great customer service :tiphat:

The sensor is mostly plastic, it's going to take some creativity to shield it from the surrounding engine heat. Even so I've never heard of one melting before, pretty weird.

Big thanks for the heads up!.... nice for someone else to 'find' one of these issues first for a change! lol ... and sorry to hear about the rough day! do you have a 'freeze frame' of the codes you picked up? i'm curious if there are other issues... the 3,500 cutoff sounds remarkably like a temp sensor issue - same for oil temp

Junior- any ideas on how to shield it?

I ll look at it this morning. That is some serious heat to melt one of thoes!

pics? location?
 

Do you have pictures of the sensor's location, or can you describe its location? To melt, it must be located externally, close to an exhaust component...

wonder if we can get this C6 rear diffuser to fit on the Z ? they claim significant downforce on the corvettte... anyone know how close the dimensions are between the two cars ?

You might want to give Fontana Nissan a call and ask for Chris who works on the race cars. Don't know his last name. Mention the blue race car and they'll get you to him.

He said it was a poor design and he also said he was going to shield it for me. He's a great guy who loves what he does. I'm sure he'll help you out.
