Yeah, the R&T test car (bone stock, obviously) ran out of steam at 5800 RPM in fourth gear.

Road & Track showed a top speed for the original 4 speed '70 240Z of 122 MPH. The test data does not say "Est.", which in those days means they actually clocked it. That said, no way I'd want to try that in mine prior to the installation of the front Spook.

I've been running non-DOT headlights here in Oregon in every car, truck and motorcycle I've owned since I first discovered H4s in 1976. Never had a lick of trouble. And a lot of the later (non-standard shape) lights in modern cars have cost me a pretty penny. But being able to see at night is worth every cent.

I've done most of this myself, only without the modern stereo. I have Dave's headlight and parking light relays, the ZX alternator and the sidemarker conversions. I'm using H4 headlights similar in power to the ones you pictured, although mine are more vintage looking. Dave's stuff is great, you can't go wrong with any of it. Similarly, to maintain the vintage look, I have a '70s Pioneer Supertuner mounted in the dash, and a few totally hidden speakers. Doesn't sound anywhere near as nice as yours will, but it looks right and is totally reversible if I should ever want to go back to stock.

Randy, the original set of wheels I had were indistinguishable from Rustoleum flat black. I went so far as to paint half of one wheel, and you could not tell where the new paint started from more than 6 inches away.

Here's a picture of a Y-collector that a previous owner had built for the Hooker header that cam on my parts car. I'm not saying this is the best way to go, or that my example is ideal, but it does show a possibility...

Typically, the 350Z drivers I see while in my 240Z are too busy yacking on their cell phones to even notice any of the traffic around them. Seriously. I see two or three a day on my way to and from work, and the drivers (both men and women) are ALWAYS on their phones. Not so for Z32 drivers. Many of them notice my car, and lots wave.

Remember that profile is a ratio. 50 means that the sidewall height is 50% of the width. So a 205/50 is pretty short, but a 225/50 is taller. So if you go wide enough the sidewall won't look too silly. Problem is that while a 225 will fit on a 6" rim, pinching it down onto a rim that narrow doesn't do the handling any good.

IMO, the 205/50s will look too small. They also have less load capacity, and so will be working much harder to support the car. The handling difference between the 50s and the 55s will be minimal, the 50s might be slightly more responsive to steering input due to the shorter sidewall. But being that the width is the same, maximum side grip will be very similar.As for the width/profile question - width is somewhat more important for grip, profile for responsiveness.

Assuming you can find a good one. These days most of the used hinges are worn out.

Yeah, being only 6" with a 10 mm offset, 225/50s might give problems. I'd look into the 205/55s.

How wide are the rims? Both of the sizes you mention are rather small. If your rims are 7" wide, look into 225/50-15. If they are only 6" wide, look at 205/55-15.

My dealer told me these are NLA, and a dealer inventory search turned up NADA!

The ride and handling is good, but you will have to shorten these springs to have a normal ride height.

The sudden change sounds like a hydraulic problem to me, as well. Check for fluid leaks, or a failing clutch cylinder - either master or slave.

Joachim, the clear lenses you are looking for were not offered on North American models. So used ones here in the states will be vary hard to find. Reproductions can be ordered from the following USA vendors: http://www.datsunrestore.com/photo4.html http://www.thezstore.com/page/TZS/PROD/ETS/33-1065

And when the chrome wears off, it's blue underneath.

The limited slip itself. Many LSDs will make lots of clunking sounds in sow, sharp cornering.

The consensus seems to be that a cherry stain is closest to the original finish. Here's a previous write up: http://classiczcars.com/forums/showthread.php?t=21485 By the way. Welcome to the forum, Larry. Where in Oregon do you and your car live?

The original mechanical pump on my '71 is fine for my four-screws. That's the only pump that the '70-72s came with, so it should be fine for your ZTherapy carbs. Assuming that everything else in the fuel system is right, of course.

It's even worse that you think, Patrick. Not only am I unaware of any other Datsuns that use the same wheel cylinder, but not even all 240Zs use the same cylinders. '70-72 used one type, and the '73's used a different type.

Hmmm. Probably something I should consider adding to my spares in the toolkit, along with regular fuses, E12-80, etc.

Definitely aftermarket.

I've got a ducted one from Classic Datsun. Since I've not seen one from MSA in person, I don't know what difference (if any) there might be. The Classic Datsun one is definitely more expensive, but the fiberglass work is absolutely first rate.

What color are you after?
