3 screw or 4 screw.....no problem with the pre 73 Z's. 3 screw or 4 screw or flat tops are a problem in the 73's. It must be something else peculiar to the 73 cars. I don't have a clue, but all I know is I never had one case of vapor lock in any of the many 70, 71, or 72 Z's I've owned, but had a problem with the only 73 I've ever owned, even though it had 3 screw round tops. How about it.....anyone ever had vapor lock problems with a 70, 71 or 72 Z? Nissan never added insulation to the fuel lines till 73 which makes me think it wasn't a problem till 73.

What puzzles me is that vapor lock only happens on the 73 and 74 Z's. even when you change to round top (early) carbs, you still have a vapor lock problem with the 73 cars. WHY???? I've never had a pre 73 Z give me a bit of problem with vapor lock....there must be a reason.....but my 73 gave me fits in the heat.....until I built a 72 motor for it....then, no more problems....why? Must be something peculiar to the 73 Z's.

Hardway.....I just finished installing Wilwoods on the front of my 73 car. The stainless brake lines are much longer with no effect on performance. It would be nice not to have to open the brake system to swing out the strut to change shocks or springs.....you would still have to remove e brake clip and outer halfshaft bolts in the rear.

Reminds me of the "Bird Dog Bra"....."it made Pointers out of Setters"!

Steve....I hope you got a chance to meet Woody, Sam Neave and Greg Ira. Sam builds all the engines for the number 46 car plus Greg's, Woody's 240 and 280 race car. Those guys are a trip....totally nuts! I almost booked for the Mitty, but too much else happening.....post more pics if you can. Guy Sounds a little bit like Italy? Sam built motor. IMG_0824.MOV

I just installed new Tokicos in my 73 47,000 original mile Z. When you pushed down on each corner, the car was soft and bouncy. I figured they must be the original blown shocks. When I removed the struts, I was surprised that they were loaded with KYB's .......just my personal opinion that the Tokicos are a better shock for our Z cars.....you'll live with your decision for the life of your car....Tokicos ain't that much more.

Bruce or Steve at Ztherapy should be able to direct you to where you can get that info.

Would love to see some pics......He'll win too! Gorgeous car.

If you get a chance Steve, stop by and take a look at my good friend Woody Staub's number 22 car. He'll probably be with Greg Ira too. Guy

This one is mean!

Jeff....I remember back in the 70's there was a problem with the worm gear ( the gear that slides onto the crank nose and meshes with the teeth on the distributor sprocket) under harsh racing conditions. The two it seems were incompatible and caused wear under race conditions. The solution was a bronze worm gear that you could get from Nissan (NLA). I bought them for most of my engines before they became NLA. Seems to me that someone was making them again.....try googling them or maybe eBay. If not, I would replace all 3 items .....oil pump, worm gear and sprocket and go at it again.

So sorry to hear about Deanna.....we lost Cheyenne 9 years ago....I miss her still.....we bought Millie...another worthless flea bag that we are totally in love with....a shame dogs have such a short life span....I feel your pain.

All finished with the 73......new shocks, springs, ball joints, tie rod ends, wheel bearings, Wilwoods and bushings. I really like the way she sits and handles with the new Eibachs.....car drives like new. Now the car is as fun to stop as it is to go. If anyone needs help with any of the above improvements, feel free to ask.

Datsuns on air......number 22 getting ready for the Mitty at Road Atlanta!

Actually, they are lighter than stock....the calipers especially.

Not sure about that Cliff....maybe someone else can answer that question. My guess is you need to match the larger caliper to a wider vented rotor. These calipers are huge, as is the rotor. It's a simple install.....Xmas is coming up....put these on your list and tape it to the fridge.

All together.....I had to put new grease caps on to finish it off. All that's left is to bleed those big calipers and button it up.

Wow....At first glance, I thought that was a long neck Bell's Two Hearted IPA ( not a jack) in front of the brake rotor. Looks good Cliff....but, disappointed that it was a jack.

Only on the vented rotors that are angled (curved vanes).

I appreciate your input......yes, I was careful to install the discs with the vanes angled back....amazing how much air flow moves through the vanes just spinning them by hand. These brakes really cool themselves....not important for street, but critical for racing.

Jason240z.....Rotors are correct....vanes angled back....sucks heat away from center of the brake rotor.........

Love your car.....cool trophy too.

Driver side.....Installed new tie rod, bearings and races....cleaned up and painted. As soon as the machine shop removes the old shock, I'll install the new shock, Eibach, ball joint and Wilwoods....bleed em and see how she sits and stops.

Wow......What was he thinking? Ramming speed grannyknot!

Wilwoods sure are Purdy!!! ......and a very easy install....now to the other side
