Next order of business was electric fan and shroud, and radiator hoses. I chose the 2016-2019 Camaro single SPAL 18" fan. it will be PWM controlled and is a very popular choice according to the internet as it can flow 5000CFM. Although I cut up the factory shroud to "work" I felt like I needed something fancier. modeled up a base to start working from and had my friends at laserbros in NC laser cut and bend it up. Should have gone one or two AWG thicker so added some bracing as well as some mounts and very happy with the final product. Cut down the radiator and inlets and outlets on the engine and welded on some -16an bungs, made up a couple hoses. in the last photo of the "hose installed" you can see the end of the pipe for the intake I welded into the chassis I mentioned in the previous post. Also decided to move the alternator to the other side of the engine to get it away from the heat. When i pull the engine to paint the bay i'll design and make a bracket to permanently mount it over there.

HybridZ is now 26! It's too old to remain on its parents' health insurance plan, and now needs a real-job, with benefits and maybe even a 401K plan. Anyone left here, who started working on their V8 Z project back in the 20th century, and is still wrenching on it? Anyone?

Got the rear calipers on today. A few challenges getting this to fit for the 240Z. Tight tolerances between rotor and caliper, needed some washers to align it right. Also getting the pad clips on were tough, some clearance issues with the wheel well as the pins go in from the back, but got it eventually. I love big brakes 😍.

Hi all, I'm new to HybridZ. I'm looking for information on the best parts to pull from a donor car I just picked up. My 240z and the 1982 280zx donor are in the pics. The donor car is complete and the odometer shows 71k. My plan was to pull the full drive train and swap it into my '72. I will save all the parts from the '72. I want to keep the car all Nissan. So, for the motor, is it worth keeping the fuel injection? I have also seen something about using custom brackets for the rear disk brakes. After I have picked what I want the rest will be parted out. Thanks for looking and good info. Bill

02-11-2026 ATLAS Z update: I got back half of the car all wired in except for a license plate light I am waiting for it to arrive. pretty cool LED unit I found on Amazon for 8 bucks. Got the headlights almost in. I always have a problem with this job. I had to break out the angle grinder and mod to get the driver's in....unsure so far far with the passenger one. Strange..... it REALLY fought me. I also got the 10AN line between my main filter and pump in, so it is ready for installation. PTFE lines take some work.

Happy Birthday HybridZ. I’m a little over one year into my V8 track build, this forum has been very helpful 💪

Well Happy Birthday to Hybrid Z !There is still plenty of time to keep playing! What a great forum it has been. Thank you for those who help keep it going! I'm close to the 20th century (2004) since i started on my Z. Still going strong

The reason for this video is investigate the Quality of Car Bodies that are produced by a Chinese Manufacturer who also produces the 240Z assembled body. The Actual Chinese Reproduction of the 2025 SEMA SHOW Toyota A86 Body was purchased and examined by several individuals who expressed their opinions about the body. The owner will attempt to assemble the vehicle with available Aftermarket Parts( tail lights, interior parts,etc. This body was the same one at the SEMA Show so time will tell its quality and parts fitment is up to the OEM Standards. This body came from the same factory as the 240Z body at the 2024 Sema Show. I checked this at the Sema Show and after watching this video, my opinion on this car is there is a definite lack of quality control in the welding of this car. There seems to be a lack of spot welds on some of the panels. On Utilized Body Cars, spot welds will determine the strength of structure. Normally, the original manufacturer would use Robotic Spot Welders on the Assembly Line. On this car, the welds are not located close together thus not providing a strong panel. Another major flaw is the Front Strut Mounting Holes are oval not round as they should be. This shows a definite Quality Control Issue. It seems that assembly of this car was rushed and put together just for the show. The Collision Industry has a established Standard -ICAR which provides proper methods of assembly of Body Parts. A ICAR Body Specialist should inspect this car before it is put on the road or used as a race car.

Second Owner of the SEMA SHOW Toyota A86 Body The First Owner of the SEMA SHOW Chinese Made Copy of the Toyota A86 Body decided to sell the body. The real question is why? The next Owner bought it with the idea of attempting to assemble the body and create a drivable car. As the body has No VIN Number and No Manufacturer ID Number, they knew that car registration in most states would not be possible. They intended to use this body as a Race Car as no registration would be necessary. As the video demonstrate that most mounting holes that not align with OEM parts. Also, they discovered a lack of sufficient welds on the body panels. Mounting brackets were missing or mislocated. So even if it was going to used as a Race Car, major welding and reinforcement of the vehicle would be necessary. So far, there has no one that I know who purchased a 240Z body from this same manufacturer. So far, we could not get a firsr hand through inspection of the Zbody and find if that body is manufactured better or not.

I started tearing down the motor today. I’ll probably work on it some more tomorrow, would like to be painting it this month. Also starting to design and fab the fuel cell supports. Going with some 1” square tubing. Got this table to attach my portable band saw, works great

02-04-2026 more work on the ATLAS Z. I got the adaptor plate for the brake master done, more progress on the fuel cell, and unpacked some stuff. Pics follow:

I got my billet column adaptor for my raceware turn signal lighting and horn control. Not too shabby.

I sat in those tillet seats at PRI this year and was very impressed with the hold and comfort despite not looking like it would be either.

01-31-2026 pics of the completed dash center piece:

Got a few minor things done today. Front and rear sway bars are on. Got the steering column mounted and quick release steering wheel installed. Also plumbed up the line-lock, just need to clean it up a bit and the fronts are ready for fluid.

Thanks for bumping this thread, good read and some good resources for me to follow up on. I will be getting to the aero parts of my build soon and this already has given me some new ideas. Balance is definitely the big thing that can be missed and tire sizing comes into play here too which I’ve already been thinking about. Most likely going with a wide square set up for the track, so increasing oversteer with just tire set up.

FYI -- I've confirmed with SuperDan that the site certificates have indeed been updated. Some users may need to refresh their browsers to update the cache or empty the browser cache. Cheers.

This matches my experience too - a lot of aero “common knowledge” starts to fall apart once you actually try to measure things. The front-vs-rear balance point really stood out to me; I always assumed any lift was bad, full stop. Makes me rethink how careful you have to be adding splitters or diffusers without addressing the whole car.

01-20-2026. Engine wiring harness. So, today I took my custom Lime-swap wiring harness for the ATLAS, and stripped off the looms and tape, so I tailor can fit everything and cut the wires down for a good, hidden fit. it's quite a bit of work removing the plastic bracket that originally held it on to the valve cover, straightening it all out, getting it all ready to be installed and then separated and cut and spliced back together correctly. I have these special splices they advertise that melt with a heat gun and solder the center.....I thought I'd try them. Some exposed wiring parts will have the chrome looms I bought over the wires, as you can see in the Injector wiring in the separate pic.

Unless somebody has a faster timeslip, fastest IRS s30 (barely) so far is Terry Garmon with 8.42 @ 166 mph in the 1/4 mile. Also included is a picture of Rick dunns 700hp car with the newest version of the rear swap, and a picture of all the components laid out, including the axles. The setup has evolved over the years, but even the earliest versions are out there putting down thousands of miles with all kinds of high and medium hp levels.

Another pic of the toggle cluster I am putting in my Atlas Z. fused and the start toggle is a momentary switch. when you flip the ignition toggle it will kill all power to the stand alone engine harness that the fuel pump runs through. I love the old school look. The quality of these toggles when you operate them you don't see often these days anymore....I got it at Summit and yep, the price is high, but the quality is A+.

01-19-2026 First survey of my customized stand along wiring harness for the GM Vortec 4200 / ATLAS 4.2 engine swap. Keep in mind If I had kept the auto trans there would be more....I also deleted 90% of engine functions as well....only kept the cool stuff like gauge feeds, etc. At least I have a wireless throttle! enjoy the video. 01-19-2026 harness video.MOV

started tackling the turbo system. designed and machined a stainless exhaust flange because I couldn't find one I liked. 304ss that seamlessly transitions the oval port to round so i can use sch 10 stainless. Went with a billet turbo flange from elmer racing. I make these kind of things but no way I could have made one for what they charge. beautiful piece. I ordered 321 sch10 stainless weld els to make the rest. after a little "writers block" i finally got a decent layout for a turbo manifold. The car came with a precision turbo but unknowing the condition and the size wasn't ideal i ended up going with a garrett gtx3076r with a v band inlet.

Very interested to see. Jim's Swiss 240Z (stock internals except for a mild cam) with ITB's and a Holley ECU tuned by our local legend - Tony at UMS - made about 183 RWHP. Jim was a bit disappointed (he was thinking 200ish) but we all thought that was pretty amazing for just ITB's and a good tune! It would be nice to see what all your engine work will accomplish. In ANY case it'll be a blast to drive!

Bumping this, the site still needs it!

01-13-2026. Just a little something to keep my motivation going. New badge and antenna delete plug from Resurrected Classics and Z Car Depot. I know, the clear looks dull, it will just need to be sanded and buffed. I'm planning on using Poppy's Patina wipe on clear in the summer God willing.

Sorry for the delayed reply. Was having difficulty with my Password and trouble posting. Thanks Administration for correcting problem. Disc brake and Hand Brake Installation- First, Important Notice-The Invinclble Extreme 8.8 Differential Conversion Kit requires the use of 2015 to 2024 Mustang GT Rear Disc Brake system. All related Suspension Parts were created to work with these parts. Check carefully if any alternate brake parts are used for fit and function. Otherwise, Different Parts may require Modification at some level. I utilized NAPA Replacements Brake Parts (Calipers, Rotors and Upgraded Pads) for 2019 Mustang GT I painted the Calipers and Mounts with Polyurethane Bright Red to improve their appearance, Stainless Steel Brake Lines(from Amazon) were used. Brake Line Adaptors from EBAY connected the Male OEM fittings to the Stainless Lines. Brake Line Adaptor installed with OEM Clip to Stainless Steel Brake Line Hand Brake Modifications- The Hand Brake required a little more fabrication to function properly. I found these adaptors on Ebay although they were not designed for this particular job. The Above Two Parts were used together to adapt the OEM Hand Brake cable to the Mustang Caliper Hand Brake Cable Mount. The Cable Bracket with roll pin must be Slit to allow the cable to fit into the Threaded Cable Mount. After being inserted into the Cable Mount, the Bracket with Roll Pin is reassembled on the Cable. The Slot can hammered closed afterwards(or even tack welded) The Caliper Hand Brake Cable Mount had to be enlarged to 5/8" from 9/16"(use Unibit) to fit the Hand Brake Cable Adaptor. Insert Cable into the Nut assembly with JB Weld Epoxy to fasten cable to prevent movement. Allow 24 hours for the JB WELD to harden. Drill out Adaptor to 5/8" to provide Cable fit. /inserting Cable into Adaptor with JB Weld to hold it. I Assembled all together With the Hand Brake completely Loose, Slide Cable Roll Pin with Cotter Pin over the Caliper Lever Arm while pulling cable. Note-Stainless Brake attached to Caliper with Bolt(with copper washers-above and below. 0 The Hand Brake Adjustment Threaded Rod must be shortened by 2 1/2". Just use a Hack Saw to shorten a non- threaded portion of the Adjustment Rod. Pic of the Hand Brake Adjustment Rod in Trans Tunnel. The Shorten Adjustment Rod will move the Hand Brake Arm forward and make it easier to access. Final Hand Brake Adjustment was made when all Four Wheels were on the ground to the point the vehicle could not be pushed be hand. Wheel Spacers- With my 17" x 11 1/2" Wide Wheels and Deep Offset, the Inner Wheel Bolts would contact the Ca[iper Outer Face. US Wheel Adaptors provided 1" thick wheel spacers which get about 3/4" Caliper Clearance. I can probably shaved the Inner Side of the Spacer about 1/2" to bring the clearance down to 1/4" Clearance if necessary. Bigger Brakes with Larger Calibers and Vented Rotors would probably fit now(trial fit to be sure) if you go to LARGER Calipers and Rotors. US Wheel Adaptors can make spacers to whatever spacing that you might need. Also, the spacers can convert to different wheel mounting patterns. Wheel Inserts with 5 Lug and 4x 4 1/2" Pattern Matt Cochan at LOVE20BEE IN California found Watanabe Wheel Inserts for me. I sandblasted and took them to a local PowderCoater to powder coat. Extended Lug Nuts- Because the Narrow Wheel Lug Pockets, I went to Ebay to purchased Extra Long and Narrower Lugs. Almost all of these 14mm x1.25 lug nuts had to been retapped with Exlarge Long 14mm x 1.25 Taps because of bad threading. Extra Long Wheel Lug Nuts on Extended Wheel Studs. Next-Struts and Exhaust Pipes
