240z drive

So yesterday we picked up my mate’s series 1 240z from the mechanic. Got to drive it a few miles on the way back. Now the wait for the end of winter is even harder!

Project Datto: Winter Update

So as the winter period is the time of the year to do some resto work and updates, here is a little update. This winter it’s mostly around the rear of the car. So I removed the fuel tank, inspected the inside and decided an outside resto is all it needed. I mechanically stripped it, put it in rust converter (KSD Kovermi) and brush painted it in Brantho Corrux 3-1, which is a primer, rust protector and paint. All in one.

I also decided to clean that mess of vent hoses which can be found on these later and US cars. I pretty much converted it to early EU/Japan layout. Put on all new hoses, restored the tank fixing straps (Stripped, rust converter, paint), new vents.
Here is a graph of my new vent line layout:

While the tank was out I also cleaned the underside. How could you not. So same process as always: stripping old under seal and paint, rust converter, 3in1 paint.

As I also had ordered new U-joints, boots,… quite a while ago I restored the rear axles to. Removed the axles, disassembled and cleaned, stripped the paint, repainted, greased everything up. Removed the U-joints, fitted new U-joints with the shop press, fitted new boots.

And I prepared everything for a rear wing install. No, not necessarily for the looks only, but to test and try to get rid of the exhaust fumes in the car. It’s worth a try!
But more on this later.

Project Datto: Roadtrip ahead

In preparation to a road trip to the French alps which will include 23 pass roads and approx. 2400km there was the urge to do some general maintenance and updates. I planned to do a Toyota front brake caliper swap to, but the parts did not arrive on time, so I’ll have to do this upgrade later.

So after driving 500km on the newly mounted 5-speed gearbox (which I bought untested 3 years ago) I saw a small oil leak, so I replaced the rear transmission seal. While the gearbox was off, I also replaced the pilot bushing in the crankshaft as it had seen better days. Another item added to the driveline is a RT Diffmount.

Another thing I had laying around for moths was a complete engine-back exhaust from Zstory. After quite some fiddling to get everything right and a homemade header heat shield, I mounted everything up. It’s quieter than my previous pacesetter/homemade/… exhaust but the exhaust note is way nicer. In order to limit exhaust leaks to a maximum we decided to weld it up where we could 😉

As I had to drain the coolant to remove the intake manifold to mount the header it was a good opportunity to flush the complete coolant system and even a better opportunity to change the tired old radiator to an aluminium Mishimoto radiator. As I wanted to stay with the mechanical fan on one side, but improve its effect I decided to fab a homebuilt fan shroud.

While cleaning the shed I even found the splash pan, which is rumored to improve cooling to. So I mounted this back up to.

Another addition are front and rear tow hooks from Zstory

I bled the clutch, renewed the rear fuel lines from the tank to the hard lines, mounted new Toyo Proxess CF2 tires in 195/65R14, changed the engine oil, replaced gearbox and diff oil, greased the U-joints, changed the auxiliary belt, got a oem replica 5 speed wooden shift knob…

And now wish me luck, I never drove more than 200km in one go, and now I’m trying to do 12 times as much in only 5 days. Let’s see if it can survive the torture. If it does, be prepared to see some super AWESOME pictures of these 2 Datsuns together in the Alps!

Finally an update on my Datto

Sorry guys, but the blog is really running slow at the moment. But since I became a father, my free time is just way more limited. Owning 4 project cars (3 vintage ones and 1 track oriented one) doesn’t help either. I’m running behind on every single car.

The 240Z’s engine bay is finished and back together. At the moment I’m fighting a bit with my brakes. Might be the reaction disc in the booster. Have to investigate a bit further.

So we left with me DIY zinc plating parts. The finish is nowhere near professionally plated parts. But I love it and the fact it’s done by me is just satisfying.

So after I chemically and mechanically stripped the engine bay, I treated some areas with rust converter (Kovermi) and later painted it in 2 layers of a 3in1 product for rust protection, primer and base coat (Brantho Korrux 3-1)photogrid_15130756883626286390548691154149.jpg

Once dry, I made my color choice. At first I was unsure if glossy black, silver, blue. But I decided to have it the same colour as the rest of the body, wich is Bahama blue #352 by Mercedes. Added a special clearcoat for engine blocks (KSD).

Some minor details have been addressed to: painted the airbox in factory orange, new rubber on the wire loom holders, cleaned the wire loom itself and wrapped it in new wire harness tape…

Next step was mounting a 5 speed gear box and starting to reassemble the bay

Made my own “molded” hoses with the help of a little trick

Engine back in, new “awesome” plug wires, diy battery hold down bracket…

I will post a complete before/after picture in the near future. Here are the 4 major stages of the bay

And just for documentation purposes, the completed interior as it is at the moment. Still need to find a stock radio some day. Doesn’t need to work, just to nicely fill the hole!
