Building a race car.. looking for advice!
jhm replied to jsausley's topic in S30 Series - 240z, 260z, 280z
...and start out w/ used race tires!!! I've been buying from this guy for a while now, and am extremely pleased. http://stores.ebay.com/Race-Tires-USDRRT?_trksid=p4340.l2563 -
I would stick w/ the 8.5" (I'm assuming that's what you've got in there now). Will fit better, and should provide plenty of brake assist. The 10" may give you more brake assist than you want. All depends on your personal preference and intended usage. Some guys are running their cars w/ no assist at all. Good luck and be sure to post your results!

Not sure what the chump circuit is, but if it includes stuff like auto-x and track days, here's what I would suggest... If you're really intent on building up this car (and there can be a great deal of satisfaction in doing it yourself, vs buying something that's already finished), I would concentrate on the brakes, suspension, and wheel/tires. You're really wasting time and money if you build a hot engine before getting this stuff sorted out first. You won't believe how much time you'll pick up just by putting on some good race slicks. And if you've never had formal training, spend a few bucks on a good performance driving school. You'll learn how to get the most out of whatever equipment you're running. Good luck and happy motoring! r/John -
Sorry, my bad. My car is a '74, and my experience is primarily w/ the later year S30s. Thx for clearing up the confusion, cgsheen!

Sorry guys, but I'm confused. The wiring at the turn signal switch is a simple 3-prong plug. When the switch is in one position, it completes the circuit for the left signal; and in the other position, completes the circuit for the right signal....true? Why can't this functionality be replicated by replacing the turn signal stalk switch with a 3-way toggle switch? Wouldn't the rest of the wiring in the system remain "as-is"? (Again, this solution assumes that the problem lies solely within the switch, and that all of the system wiring is good and can be used as-is.) Again, my apologies if I'm over-simplifying the problem...electrical issues are my weakest area. r/John

Yep. A leak in the booster system (booster, hose, one-way valve) equals a leak in your intake vacuum, which will increase your idle revs. It's a double whammy, because your engine is revving up at the same time that you're trying to brake (which is harder to do because you're losing the brake power benefit of the booster). Before buying any new parts, inspect the entire system, beginning with the booster vacuum line connection to your intake. One easy trick to help zero in on the problem is to reverse the one-way check valve in the vacuum line between your intake and the booster. If it solves the high idle problem, then the problem should be between the valve and the booster; if it doesn't solve the problem, then your leak is probably between the intake and the valve. I had a similar problem with my booster a couple years ago, and it turned out to be a small crack in the hose connection on the booster (below the master cylinder). Was able to easily fix it with gasket sealer. If it does indeed turn out to be a bad booster, I think Centrix is the cheapest remanufactured replacement unit. Here's one for roughly $80: http://www.partsgeek.com/gbproducts/DC/6634-05121002.html?utm_source=google&utm_medium=ff&utm_term=1975-1978+Nissan+280Z+Brake+Booster+Centric+75-78+Nissan+Brake+Booster+77+76&utm_content=DN&utm_campaign=PartsGeek+Google+Base Good luck.

Appears to be a 70's-era TVR. Very cool British sports cars that packed a punch when properly equipped. http://auto.howstuffworks.com/tvr-sports-cars.htm/printable You could probably pick that one up for a song, and you'd never have to worry about what to do with your weekends for the next three years!

Sure...why not. I would think a 3-position toggle would work -- you'd need the style that gives you two "ON" positions and one "OFF" position in the center. Something like this should work fine: http://www1.mscdirect.com/cgi/NNSRIT2?PMAKA=79483988&PMPXNO=24096938&cm_re=ItemDetail-_-ResultListing-_-SearchResults Should be able to use your existing wiring on the steering column (and existing relays) provided it's all in good shape. I doubt this setup would pass a state safety inspection, but that may not be an issue for your particular situation. Unless you use the hazards often, I wouldn't even bother messing with them (which would definitely fail state inspection). I can't remember the last time I used my hazard signal. Good luck and happy motoring! r/John

Hard to tell for sure from those pics what starter that is. Best bet would be to remove it to see if there are any markings on it (GM products should have part number stamped on it). You will also need to remove it in order to do a tooth-count on your flexplate....that's not as crazy as it sounds. Get the car up on jackstands, remove the plugs, stick a long-handle ratchet on your main pulley bolt and crank away. I used a piece of chalk to mark the teeth, and pen & paper to keep running tally of teeth counted. This is also a good way to verify that the teeth on your flexplate are all in good condition. WRT starters, I've been using db Electrical for the last couple of years. They make a good product at a good price, and their customer service is unbeatable. I'm currently using a previous version of this little beauty; weighs only 7.5 lbs and features full support for the pinion gear at the nose: http://www.dbelectrical.com/p-1319-new-chevy-305-350-454-mini-racing-pmgr-starter-ht-pm300-sdr0031.aspx Good luck. r/John

ZG- You might also get more response if you post this in the "Interior" sub-forum. Or the "Parts Wanted" forum, if you're looking to buy something. If you're attempting to fit a dash cap, leave it out in the sun for a while before working on it....softens up the plastic a bit....makes it more flexible and (slightly) easier to work with. Good luck with it. r/John

Definitely check the distributor. Best technique I've found to dry it out is pop off the cover and blow out the insides w/ compressed air.

Finally after seven years we have ignition
jhm replied to 4.6StangRage's topic in S30 Series - 240z, 260z, 280z
Congrats! Have you thought about putting some of that "4.6 Stang Rage" in the Z?? Makes for a potent combination! Good luck with the rest of the revival. -

Yeah...there's several people that would like a pair of those stainless straps. Unfortunately, Jerry (the vendor) hasn't been active on that thread since 2009. If anyone has personal knowledge on whether he's still making the straps, I'd like to know. Looks like he could sell several sets immediately! Thx. r/John

It's a late '74 260Z. I e-mailed you...looking forward to hearing back....maybe we can do some business. Thx!

Bump...still need brake booster.

HybridZ custom suspension design thread

Come on, Mark....keep up, man!! -
Yeah, Jerry...please count me in too if you're still making these. I've got a late '74 260, so I'm assuming I'd need the "early 280" style straps. r/John

Looking for a good, working brake booster for 1974.5 260Z or 280Z. I realize boosters from other years can be made to work, but I'd rather not go that route unless I have to. I have PayPal and shipping would be to zip 23602. Thx for looking! r/John
