How would you build a DSP AUTO-X Z

[Curtis240Z]

Update/backdate. Very early 240Z arms are shorter by a little bit.

Good to know. Thanks!

The drawback is the ball joint stud taper. You need to have the early arms machined to match the taper of the later ball joints. That's a gray area and might lead to a protest, if anyone is smart enough to figure it out. A defense might be that the original ball joints are NLA and this is part of a normal maintenance/repair process.

Jon,

Which stock cam is a "C" cam?

BTW, did you send in your support to the SEB regarding this proposal?

Vic's "full interior" was an interesting interpretation. It clearly was determined to be legal as it would certainly have been protested at Nationals when he won with it. It was, as I recall lightweight carpet screwed to the door panels and the same on the floor. It wasn't so much THE full interior as it was A full interior.

Very fast car and driver...

Anyone protesting that would have to know Z cars and your car like a brother. Not likely to be noticed.

The "C" is the cam from the 260Z if I'm correct. Again, this swap is a gray area thing - actually, its plain illegal given the update/backdate requires the engine to be swapped as a complete unit. But, based on how SCCA tests cams, the specs will be within their range of error when they measure duration.

Its not that critical of a change because the power difference is very small.

I sent an e-mail in requesting the change, although I'm not going to build a car for the class. I was much more interested in the short lived proposal to put the 280ZXT on the same line in BSP as the 240Z.

[Curtis240Z]

If the proposal goes through my car is ready. I just got to get the travel logistics organized and that is a very expensive task considering my location, but definitely worth the shot.

[tholt29]

If it does go through, it will not become effective until 2011, so you should have plenty of time to get the travel plans worked out...

What about a ZX?

Would it be too heavy?

Stiffer chassis than the S30? I have no idea but if the ZX is the bastard child then it would be fun to get one competitive, put some noses out of joint.

[jmortensen]

Richard you are WAY too happy on the ZX. Curtis, you really want to ship your car 5 or 6000 miles for 3 minutes of seat time and a trophy IF you place?

[tholt29]

Making a competitive BSP ZXT will be a definite longshot... It's been in that class for decades and I haven't heard of anyone doing it yet. The Evo's are dominating that class and show no signs of letting go.

If the proposal goes through I'll take my Z to Nationals for sure!
