I'd suggest Taylor as well, they're top notch and competitively priced, at least when I bought mine. No personal experience with a clutch style, but I installed a temp probe in my R200/Quaife last year. My first event was unseasonably cool (70's), I was the last race group of the afternoon so it had cooled to ambient temp, and it still hit 300 at the end of a half hour session - this with the 300zxt finned diff cover too. Needless to say a cooler went on shortly thereafter. Prior to that I was changing the fluid every race and I can only imagine the temps.

Unfortunately Greg wasn't able to pull it off. I watched the live web cast, which was very good BTW. The race weather started off with a sprinkle but degraded quickly from there, it rained quite heavily at times thereafter. Just going off my memory, Brakke spun in T1 on lap1, Prather went off in T8 also on lap1 (maybe lap2). Greg, who I'm assuming was on full slicks, kept it in check but was soon passed by a few guys and later came in to change tires. Looks like he set fast lap of the race after, finished 9th. Here are the results: http://www.scca.com/popup/raceresult.aspx?event=13506&file=1008 I can't help but be happy for the race winner, Sam Halkias and his TR6. He's been racing that car FOREVER and usually a mid-pack car at most runoffs IIRC. Prather had his car painted in Tom Thrash livery and flew the Texas state flag on the warm up lap, nice touch.

Thanks! Good vids.

I never tire of seeing the car, beautiful, and thanks for the photo links Alan. A dream venue of mine, I hope to make it there one of these years. The sounds of vintage race cars at speed AND Merlin powered aircraft.. heaven!

Thanks for the update. Great news, .1 seconds is a huge improvement over 3 at the Sprints. Interesting note about his competitors, I would've thought Brakke was the guy to beat.

Many years ago I mounted 240 bumpers on my 280. I simply sandblasted them inside and out, welded all the trim holes etc, skimmed a coat of bondo on, and painted. They turned out pretty good. Sandblasting aids paint adhesion as well.

No hard feelings personally, I was only joking thinking it was a misprint. Nonetheless it sounds like a wild ride, any pics?

Try some searches, there were some very good rebuilding posts by a member both here and on Hybridz, wanna say his user name was hisandhers on both sites. To reiterate, quite often simply replacing the brass synchros themselves won't entirely cure the grinding problem as the synchro hub springs tend to "relax" over time. Zdoctor - last I checked he hung out on zcar.com, sells some stiffer stainless replacement springs. I picked up a set from him but have yet to use them and can't offer any first hand experience. Here's his website, but last time I tried to contact him the email listed was invalid: http://www.thezdoctor.com/ EDIT: Welcome BTW!

Yes, congrats to all z guys! With that said it looks like Tom "jumped ship" and is now running a vintage 1974 Evo

Just reading through the SVRA group 8 rules and they list two acceptable rear spoilers. The first is the infamous BRE style, 4" tall, Nissan p/n 98100-E3300, which we're all familiar with. The other which I'm curious about is the 280Z rear spoiler, p/n 99996-R8Z01. Does anyone have a picture of this? How tall is it?

Very cool. Any individual, higher res pics available too?

Pretty cool, that's an autocross on steroids! I'd love to try out a course like that. Heh, I forget you're in that line of work, I was expecting some home video footage, not these, nicely done!

Thanks for the vid. A friendly fyi, your link doesn't go directly to the EP race, for the others it's race #4. Ironically, I met the driver of the #47 roadster (the "smoker") this past weekend, he was instructing at our club's Sat drivers school. I hadn't planned on attending the runoffs but some of my fellow drivers had talked about going as spectators. Nothing concrete, but there's a chance I'll be there. Tell that to the 5 of 7 Z drivers who DNS'd, DNF'd, or had limped through the race with problems at our Council race @ Blackhawk this past Sunday. We had no less than 6 Z's (including myself) in Vintage - possibly a record. Bill Oakes and I were the only 2 who escaped the "bad karma". A good weekend for me, won the race with a 19 second lead over 2nd place.

I found a good gallery with many good pics of Greg and John's dice: http://dennisw.smugmug.com/gallery/8736269_bXH6W#587324618_fTFha Here's another one, not though quite as good: http://gordon.smugmug.com/gallery/8893659_iHYkF#P-4-15 Both photographers have a gold mine of years past Sprints as well as other events too, just click on their username. Greg, the #67 on the airdam was a nice touch!

2 seconds, great to hear! The real test for myself will be next weekend @ Blackhawk, can't wait! The first event on the Bilsteins was at a new track (for me), but I appeared to be running faster than my nemesis - a wild Ford of England '72 Escort with a twin cam Lotus F2 motor. I'll also be on old rock hard tires deliberately (victoracers at that). In my case, the car is not loose with the rear bar either. For anyone interested, here's a vid from the aforementioned race - from Bill's perspective in the ex-Mountain Motorsports ITS 240. Unfortunately he was just a bit too far back to catch my duel with the Escort, just a dot in the distance. I missed the grid call and started a lap down (don't ask why :mad:) , doh! Ran with the escort for about 5 laps but let up after that, what's the point?

Looks like a run-of-the-mill "b" box 4 speed (F4W71B), to me.

A popular swap is the earlier non-EGR N42 manifold, found on the 75-76 years.

Good points, you should probably hold off on diving in with the checkbook just a bit. A good starting point for diagnosing any head gasket problems would be a leak down tester, done both at cold temps and after warm up. Also, if it's truly leaking antifreeze into the exhaust it will give a very distinct smell otherwise the smoke could be something else. Yes, I don't envy you, the climate here in Wisconsin is bad enough! On a side note, I'm pleased to see the IRL kept the Edmonton race on their scheduled this year, in just a few weeks too.

The intake manifold only has a mounting provision for the "cooling loop", there is NOT any orifice at that point which would allow coolant to seep in, it' my guess you overheated and warped the head. The loop is only needed to warm the air regulator, it operates independently from the Thermotime switch. Its only function is for high idle warm up - without the "coolant loop" the car will high idle indefinitely in colder temps, speaking from experience on that one! For anyone in warmer climates, I would recommend removing it completely.

The internal-strut-housing spacers were fab'd using rigid plumbing pipe from the local Home Depot. The 1/2" tall spacers at camber plate area I made by cutting the tops off the old tokicos and drilling the abandoned adjuster hole larger. Sounds ghetto but it worked pretty good. I was worried the struts would be hardened steel but they drilled very easily. I already owned the GC camber plates and made no mention of the Bilsteins when ordering the coil overs. BTW, I have an older set camber plates, p/n CPZ.

It's a bit confusing but no, I meant remained. They were changed/shortened from OEM back when I installed the Tokicos and in my case "remained" the same when converting to the Bilsteins. I suppose we need Coop to clarify. I interpreted his post as the rears were sectioned (w/spacers), only too much for the AD's travel. IIRC, GC's instructions were originally written for the Tokico's - using the front S30's as mine were. I feel safe saying he had to use a spacer as well.
