Hopefully you are converting to all SAE / AN brake fittings. It's a real pain to have a mix of metric and SAE. I routed my brake lines inside the cabin to get the brake lines away from heat. I'm running a Wilwood Tandem Master Cylinder (7/8" bore) and use a proportioning valve installed on the drive shaft tunnel.

I have been. And for those searching its nivlac57 on YouTube. I have a 84 maxima wagon and I measurd once when I had my engine out and it was to close to try. I am interested in yhe 5 cylinder though as it would fit under my hood.

Picked this up from local hot rod shop for my 240z SBC 350 project about 13 years ago. Circuits: Electric fan relay Fuel pump Radio and amplifier Power windows Summit Racing/parts store etc probably have this fuse box.

I found it just by digging around online. Wilwood makes the assembly, allows me to run two different sized master cylinders for front and back, and on top of that the horizontal bolt close to the firewall allows me to adjust brake bias between the cylinders, lots of adjustability. It comes with this cable so I can adjust the brake bias from inside the car. Yes, all new brake lines. I bought pre-bent hard lines and some distribution blocks. Once I get the rear suspension off, I’ll replace the lines, then figure out how to attach the cylinders, probably get some flexible stainless steel lines for that.

looks like i have to open my steering column next winter, i think i have play on lower splines, upper bearing might have also something going on. anyone has good link for that kind of operation on fresh memory?

Seppi72? what power window stuff / kit did you use?

I've used these....

That is an interesting master cylinder set-up. I haven't seen that before. I assume that you will be running all new brake lines.

Cut out the indented areas & fabricate new sheetmetal to fill the holes. Personally I like the smooth look. 😎

It's not uncommon. I added a terminal post near the battery for a few things. If I had a bunch I'd probably just install an auxiliary fuse box. Otherwise you have a bunch of inline fuses to take care of. There are many out there but a trip to the salvage yard would probably find one that is weatherproof and high quality. Depends on where you want it mounted. Looks like I'm on the same page as jhm, who replied as I was writing.

It can be confusing when talking about technical areas vs car model areas, but we do have the "Ignition and Electrical" sub-forum here: https://forums.hybridz.org/forum/16-ignition-and-electrical/. Yes, I think it's fairly common to add new circuits/etc to these old cars. I've done it to the last couple of my cars to simplify/improve the electrical capabilities over the stock harness. I've always used off-the-shelf breakers, relays, fuse panels, switches; but there are a bunch of pre-built kits that are available through numerous vendors. I like to use marine hardware if I can find it; as it's typically extra beefy and durable. Good luck with it; and please be sure to post your results once completed!!

There doesn't seem to be an electrical forum on HybridZ so I thought I'd put this in the model-specific one. I am in the process of adding several updated accessories to my original-owner S30. In particular: power windows, Vintage Air A/C system and RetroSound Motor 4 radio with quad speakers. I've already installed Dave Irwin's headlight relay system to take that load off the combo switch. I have a rebuilt 280ZX alternator from MSA to supply power once the Optima red top kicks things off. With all these new accessories, it occurs to me that perhaps I don't want to be chopping into the existing dash harness wires to provide them with power. So I'm thinking about installing positive and negative busbars on the interior firewall that I can hook up to as needed. Is this a wise idea? Has anyone ever done this mod and, if so, what parts did you use and where did you locate them?

Got the front coilovers and the dual master cylinder assembly on today. Still too hot out for working on the car here, I can’t wait until it cools down. A few challenges with each, but got it on right. Was hoping to start tearing down the rear, but I’ll give that a go next weekend.

Nice, I could see building a dart block sometime down the road. Just a cam and twisted wedge heads on the 302 for this build for now.

Has anyone been following the progress of these engines? The aftermarket is starting to really grow for this engine. "divlac57" is the guy who has been spearheading a lot of this Anyone else watching any of this come about??

Just some quick updates, after finishing chassis preparations and dropping off the shell for restoration last month I've been organizing my garage and have finally got things in a reasonable enough state to continue work. For the turbo build, the plan is to refabricate all fluid lines as SS hardlines so I've set the engine/transmission to ensure I get all of the angles for drainage and thermal siphon correct. It's really nice to be doing all of this work fully accessible, but I'm going to attempt to ensure the routing I fabricate can be serviced back in the car as well. Also for the driveline, I saw on IG someone had used the same CD bellhousing from Derek which locked up on their clutch when assembled. So I've put in the OSG twin plate and will check if the bellhousing needs any clearancing for the rotating assembly.

First off, welcome to the forum and good luck in your search for a Z car. In our "FAQ" section, you'll find hundreds of excellent discussions on common issues, modifications and repairs on the Datsun/Nissan Z cars. Without knowing the asking price, your mechanical abilities, and your ultimate plans for the car....here are a couple of things to look for: - Inspect the floor pans topside and underside, the frame rails, the rocker panels, and the inner fenders for rust/damage/shoddy repairs/fiberglass/bondo. These are some of the areas most often rotted out and/or poorly repaired. If the car really has "all new metal", it should be apparent via inspection. - Are you comfortable buying a built engine just based on listening to it run for a few minutes? If it smokes heavily, has significant clatter and/or rattle in the valvetrain; those are just a couple of signs that the internals are suffering. Visually inspect the oil, trans fluid, coolant, and brake fluid to ensure they all look clean, fresh, and uncontaminated. The car looks neat from those couple of photos; but unfortunately, people often buy someone else's unused "toy" only to find that it doesn't live up to their expectations for one reason or another. Do as much research on old Z cars as possible before buying anything, to ensure that you don't fall into this trap. Looking forward to you joining us as another proud and happy Z owner!

The dyno chart for that was from my old 331 stroker: Stock Roller Block (4.030" bore) Eagle 3.25" stroker crank and rods Mahle 4.030 Pistons Custom Hydraulic roller cam (.571" lift) AFR 185 heads 1.75 Long Tube headers 30# injectors I scattered that engine at Daytona My new engine is a 347. Dart SHP Block (4.125 bore) Scat 3.25" stroke forged crank and H-Beam rods Custom Hydraulic roller cam (.625" lift) AFR 185 heads Long Tube headers 42# injectors I use Megasquirt MSPNP 2 to tune both engines.

I will do this -eventually. I did pull the center ITB and tested the flow past the butterfly using a vacuum cleaner . Not sure thats an appropriate testing method but the sync tool showed same flow between the two ports. So maybe my issue with 4 is a porting of that intake runner at low flow. At this point I did another valve adjustment -cold- and I did end up finding small adjustments needed, so we will see if that changes anything. Meanwhile I am going to use injector trim to even things up the best I can before Zcon.

I have had a lot of problems with the throttle cable and related parts. a late night job came up with an extremely basic solution for cable hookup at the carb....I made a bracket and got a brass cable stop at Auto Zone, and the gas pedal bottom edge hitting the floor keeping full range from happening were the culprits. FIXED.

Keep in mind for a 240Z it is rear wheel drive so to me the best RB swap would be an 2 WD RB 30, or a 2WD RB25. For a more demanding big HP version of those the pan must be rear sump, larger capacity, have the oil pickup designed to match the 2WD RB30 or 2WD RB25 at a minimum. I literally spent days searching the web and so did Robbie at RIPS Racing. I sent him so many links and none of them had what he knows is needed to keep the RB engine reliable, especially when it will be putting down big horsepower numbers. The JHK from UP Garage had one their website that it was for a 2WD RB20 or 25 block which is the same as a 2WD RB30 but that was not as claimed; If I had used that pan it would have severely damaged my expensive engine. Thus plan on a custom pan if you want the engine to last...

Coilovers showed up today 🤩. Got them assembled and will get the fronts on the car tomorrow.

Looks good and sounds good. Wouldn’t buy without a test drive though, he’ll start it though right? Hopefully just fluids and new tires and you should be good to go. Good luck!

Always liked the early Zs especially a 240z a this guy came up for sale recently - seeing it in person tomorrow so I'll have a better idea then - apparently being sold because the guy is retiring and getting rid of all his toys Pros: 1. Bodywork done - "12k, 1 year spent at body shop to cut out all rust and install new metal" 2. Modifications: Small block chev. 600 lift Roller cam, Gold roller rockers,202 aluminum heads, MSD ignition&box, H.P electric full pump, 150 shot NOS system (Not used). Purge lighting built 700R Trans&Convertor, B.M. Shifter, I.R.S. 3.9 Gears Custom built half shafts (Good for 600HP), New weather stripping/INT/Roll Bar. 3. Looks on pictures that it's done right - looks like a very clean install Con: 1. Sat for 10 years since 2015, 3000km after the build (Drove the F-type jag he got instead). Apparently just started couple of times a year to keep things "lubed". Recommends all fluids changed, brakes bled etc before driving - so I won't get to test drive it and make sure everything's working properly before I buy it. Looking for recommendations on what to look out for, and key things to prep to get it ready to get back on the road.

Thanks guys. Making me feel confident in my set up. @74_5.0L_Z good info and impressive dyno on old engine, I’m hoping for something close when I’m done. What is your new engine, still a ford 302? Slight change to my diff setup. Didn’t do enough homework, but I think it’s actually going to come out better, just by dumb luck. I didn’t realize auto vs manual was a different sized pumkin on the 370Z. I bought an auto diff, and the wavetrac doesn’t fit an auto. Good news is I really wanted the 3.3 gearing and that only fits in the auto pumpkin (dumb luck). An OS Giken diff fits with the 3.3 gearing in an auto diff, so it looks like I’m going that route. A little more money, but the OS Giken is better for a track car anyway.
