found some corrosion on the front of driver side rocket panel.   Could not determine how strong the rockers were without cutting them open.  I constructed body bracing inside the car just above the floor pan.   The bracing was mounted to the two lower door hinges mounts.  The outer seat belt mounts were used for the other side of the body brace.  1" square steel tubing was used in a crossing pattern to provide support for the floor pan.  I want to make it bolted in instead of just welding it .Construction took about

two days with all the fitting that necessary.

‘73 240z powder coated chassis with roll cage.  Has the frame rail sleeves.  Will be doing more reinforcing.  L76 6.0.  Planning on replacing most everything but the crank.  TR6060 and Ford 8.8.  Full Apex Touring Pro front and rear.  Apex steering rack and axles.  Akebono brakes.  BRP front sump oil pan.  Leaning toward iMSA widebody kit.  Corvette accessory setup, vintage A/C and electric steering assist.  Want to be open to procharger in the future.
 

Any advice on what I should be looking out for, or changes?  Open to anything!

Thanks in advance!

I also pulled pistons and checked bearings. Damn things looked like new and measure good so I reused and increased the gap on the top rings for boost.

All this will be mated to the same drivetrain I had in the rb Combo.

Powerglide, ford 8.8, currently 4:56 gearing but will be going to a 3.70

Do to the way the trans tunnel and chassis was built around the RB the ls motor will sit a little more forward then a typical install which will make getting the BW480 in there a challenge.

I was thinking of starting a thread about my LSA swap but i know there are several but if you are interested i'll post😀.

I have a 260Z bought three years ago, drove it with the Inline 6 for two years.

I started with the brakes as they were not so good so to speak.....

I bought Porsche boxter S calipers from a 2016 and discs from a BMW F30 335i made new brackets and twin master cylinders.

At first i made new hubs in aluminium but have now changed to hubs from a S13 as i had some flex that made my brakes a bit unpredictable 😱.

     This is how it started for me. About 4 years ago I was watching a video on Youtube of a LS swapped Z car and thought, that looks like fun. So here I am. I purchased the car from a gentleman in Colorado that had previously bought it from California. It was his "backup Z" incase his was wrecked or stolen. He decided to liquidate so that's when I swooped in and got it for a mere $2,000. It was a great deal. An all original Z car with very minimal rust and 85k miles. I trailered the car home and I immediately started in on the L28 engine and getting it running. I'm sure it sat for about 22 years from what I could tell because it still had a 1986 California liscense tag on it.  The goo in the gas tank was not easy to clean. Within 2 weeks it was running and I was driving everywhere. Then the parts collecting started for the swap.

     I'm more of a picture and video kind of person so I'll keep the story time short and start in on the specs and pics. All custom components were made and installed by myself except the exhaust,fan shroud and JCI swap parts.

Apparently this is old news, but I just found out about it. You add 2 copper oil drain plug washers under the shifter detent bolt, and it makes the T56 shift much better. Anyone here done this?

*sorry if this has been discussed or if I’m in the wrong sub forum. 
 

I will post install pictures, installing in my 240Z LS2/ T56 with Hoke performance motor mounts.

If anyone has questions on the install let me know.

I thought I might as well start a build thread at some point. I've been lurking for a couple years and posting a few questions and comments here and there. I bought my '71 Z on Labor Day weekend, 2013. It came with an uncompleted RB25 swap in it. When I bought the car I was looking for a 240z to swap an LS1 into, but this looked like a great deal so I picked it. I thought I would complete that, but gave it some thought and decided I really wanted the V8 rumble and torque without having to figure out turbo technology or spend too much time on a dyno figuring out how to get what I wanted, which was a V8 anyway. So pulled that swap and sold it for what I bought the whole car for.

Since then I've completely disassembled the car and put it on a homemade rotisserie. I've replaced some rusty panels, most notably the battery area and part of the firewall, one of the tool boxes, and part of the rear tray. The floors were a little beat up but pretty solid overall so I installed Bad Dog front and rear frame rails. Fabricated a mount system for a F-Body gas tank, which has it's own thread. I stripped the underside of the car to bare metal and am in the process of coating that now.

I've been collecting parts for a while as well. I picked up a '98 LS1 with about 87k on it. I have the JCI mounts and headers. A nice Griffin 4 row aluminum radiator. A MN12 from a GTO that has bad 3-4 synchro that I'll rebuild.

I'm also going with the TTT R230 rear end setup. Waiting on those parts to arrive in the mail any day now, along with an AZC coilover set. Already have the r230 and all associated parts out of a Z32TT.

At this point, I'm not too far off from dropping the car back on the ground. I'm trying to do all that I can while it is up in the air but not sure how far I can go on the suspension while it's on it's side. Maybe the control arms and diff mount, potentially the coilovers but I'm not sure I can weld I the camber plates with the car so high up on the rotisserie. Definitely want to get the brake lines and fuel lines back in first.

As for the cars intended purpose. It will be primarily a street car. I'll find some time for autoxing, but I don't care about being competitive so I'll just run in whatever class they let me. But for me it's more about the build than the completion. Something to do with the spare time I don't even have. As my signature points out, this car will get done when it gets done, and not a minute sooner.

I'm getting started on swapping an L83 out of a 2017 Silverado into my '77 280z. Progress will be slow as I'm working on a masters away from the car right now, but I figured I'd post what I've gotten so far. Info seems pretty scarce on these engines as well, so maybe someone will find it helpful.

I'll be keeping the engine stock and mating it with a T56.

Here is what I'm starting with:

Here is the engine and transmission, T56 is out of an 06 GTO. The L83 is a bit weird and the crankshaft is not meant to accept a manual transmission so requires a 3/8" spacer on the bellhousing (not shown, but where the gap between tranny and bellhouwing is. Apparently leaving that out will result in a broken block 😕

Bits and pieces along the way (new struts, springs, air dam, wheels and tires, LSD R200 with AZC bar, bushings etc

Ran the 240 with stock motor and an MSA header and exhaust in my local AutoX (11 y/o daughter ran her kart) and we both won our classes for the year....

Picked up the little gem (98 LS1 T56 with 108K on the odo), to AutoX while the Z is getting prepped....

And the games begin..

CXracing Kit ordered and on its way.   Updates and a thousand questions to ask the Hybrid community as the build progresses. 

Is there a kit or conversion for the oem 260z transmission to work with 'any' crate motor v8's, LS options?

The plan is to swap motors and use the original transmission, if I'm able to. Appreciate any feedback and help!

Video shows symptoms. Drove the Z to a friend's house, camped out in it overnight, used the battery to run a fan. Battery wept and humidity made a lot of corrosion underneath, but the wires are good.

Tried jumping it with another V8 before swapping battery, to no avail.

Bought a new battery and swapped it out, same symptoms.

Tried starting in P and N.

Need to get multimeter out of storage to do more testing.

As you can see from the video, it builds rail pressure in between 20 and 40 PSI, but then just keeps looping that. It never stops priming and never reaches the desired number. The engine never turned over and the starter always clunks. It feels like it's being stopped by something that isn't the starter or motor though. Fuel pump is in-line/out of tank.

Absolutely no symptoms from starter or fuel pump prior to this, car was running well. FiTech is showing no codes but I have a battery disconnect switch that I use every time I park so it probably won't be showing codes. 

Has anyone come across anything like what the video shows?

02 Camaro LS1, 4L80e, Ford 8.8, FiTech EFI

C7 Corvette 600w fan with integrated pwm controller

2008 Ford Fusion fan and pwm controller

Could not find the exact size/dimensions of these fans so noted the radiator dimensions.  Also got to thinking of just swapping the compete Rad/fan setup from either of these cars.

C7 Corvette is 17.25x18.5x1

Fusion 17x25.75x1

These are single core radiators!  Is it advisable to use a single core in the S30 chassis?  Always thought the more cores the better in radiators.  How times have changed!

CX Racing has a nice 3 core 18.5x25x2.5 for under $200 made for the S30 chassis which very similar in size to the Fusion radiator so it's fan should fit well.

1. Year of motor/mods

2. Tranny

3. Kit used or explanation of your custom mounts.

4. Any special accessories or parts needed for the swap, including fuel, wiring, etc.

5. Date you started on the project, date finished

6. Other car mods (suspension, brakes, etc.)

Optional:

Pictures and miscellaneous info!

The car is just a nice weather street cruiser so I would prioritize a fat midrange above peaky high rpm power. I have stock valve springs too but I'm willing to swap them out as needed. Also its a t-56 manual trans. 

Thanks for any recommendations!
