AutoX.mp4 I'm not particularly good at autox as you can see here, but it made for a fun video.

Good new and bad news! Good news I am still here and happy to answer questions. Bad news there was only one car I liked better than the 280Z and well... It was cheap and I could resist, but only one project car at a time is in the budget, so the Z is off somewhere in Texas now. The skyline is currently getting an LS swapped into it, so if you were wondering which way I'd go if I did it again that answers that, but the LT is still good and its much more unique than an LS. As far as engine mounts, I'm not sure whats available now. It would certainly be cleaner to fab a custom upper mount to use with the DD lower mount. The mount is already poly. That being said, you probably wouldn't want it any lower than this, since the holley oil pan was already flush with the bottom of the front crossmember. You can see the oil pan on the left here, its already pretty low. Doing it again I would move the engine further back. If you make a custom upper motor mount you can avoid the interference with the LT vacuum pump boss, which should allow for the engine to be moved further back. I think I blamed the high pressure fuel pump as a reason to not do it, but I was just lazy. The only difference between auto and manual would be preference and the engine and ecu are already design for an automatic transmission. So a few tuning things will probably go easier with an auto and you wouldn't need a bellhousing spacer. This was my first(ish) engine swap, and as long as you keep it simple (no A/C, power steering, "while I'm at its", etc) the Z is really a pretty easy car to swap these engines into. LS vs LT is a hard one for me to answer for you. I picked an LT because the LS swap is quite common on the Z and I wanted something different. LT has complications the LS doesn't have, and fewer online resources and aftermarket parts. It's not a huge difference though. The pedal I used is an LS corvette pedal (19417903), they are compatible with the gen V ecu. HPtuner and probably any other tuning tool has an option to quickly calibrate the throw of the pedal.

There's more clearance under the hood than you might think. Unless you have the truck intake or something there's plenty of room for an LS in these cars without any ground clearance issues. I have a goofy throttle body setup on mine that sticks way up, but it still clears the stock hood.

So this isn't entirely helpful, but here's some pics of my LT which is approximately the same dimensions as an LS. Done correctly, I believe there is room to get the damper behind the steering rack. The LT didn't have full adjustability on the dirty dingo mounts I'm using, so I would have needed to modify them to move the engine back. Depending on oilpan you may not want to go too low though. Mine is flush in height with the front crossmember.

Perfect, thanks! Also, it sounds like you already have the aluminum, but I pulled the trigger on these uprights from sendcutsend yesterday and it was still only $100 for the two in 1/4" 6061. I thought it was worth it to not have to gum my way through the aluminum and its about the same price as the plate.

Any chance you could measure the chord on the 9 lives second element? I'm now working on a carbon/foam core wing for autox mainly and layup went poorly on the second element so I'm thinking I may just give in and buy that part if its around the right size. Looking forward to seeing your mounting, I've yet to mock anything up there.

I like that hatch, the recesses for the hood latches is a nice touch. Any chance you'd be willing to share that 3d scan file? I've been trying to find one for a while.

The TR6060 uses a different tailhousing than the T56, so the mounting points will be different, but I'd imagine it would be fairly easy to adapt a T56 mount. brackets like this are available: https://animalsspeedshop.com/products/gm-tr6060-transmission-mount-conversion-bracket not sure if they actually match the T56 mount location, but should make it even easier.

I think he's referring to the arch over the leading edge of the wing, most of them are just flush with the upper surface.

Definitely interested in what you come up with. I've been thinking about going for this project as well. Just spitballing, but the frame edge around the hatch has never struck me as a particularly weak location, I would think it could handle the ~250lbs each without the 1/8 aluminum?

I'm using an LS7 clutch, I think most LS clutches are compatible, the important part is the flywheel is 8 bolt, so you need to use a flywheel for the LSx or CTS-V, not 6 bolt like most LS flywheels. I used a Mcleod 1302 for the hydraulics, but if you have a T56 Magnum this is the wrong part, I had to file a ring off the base of the cylinder to get it to mount properly to the magnum and for a while the clutch felt like a compound bow with the give point right at the clutch engagement point which made it very hard to shift smoothly, its broken in or something now and feels much better. That being said, no spacer is needed for the slave cylinder, just get one with the correct throw dimensions, the 1302 has a range of 2.31"-2.5" for reference.

Cool to see someone also doing this swap. That makes 3 I've seen total so far including this one. Glad to see the manifold info helped, yours looks much cleaner than mine. The holley extension should help a bunch too. I cheaped out and didn't redo the pulleys, so I couldn't install the throttle body that way. I used two silicone 90s and an aluminum tube for the lower radiator hose. I used MIO-MMCP-1590BK for the lower and VPE-2749 for the upper half along with a 1.5" aluminum pipe. As for what I would look out for, it would definitely be the software and electrical side of things. I'm not sure if it has gotten any better yet, but deciphering what pin of the ecu does what is a mess since it varies between cars and years quite a bit. Tuning is still a running issue I am having. I tried to tune the car myself and having never tuned before it was way over my head with its torque based tables and driver demand. It still is way over my head. I had local shop dyno tune it and the power is better, but the throttle is still weird in its response sometimes and I occasionally have rev hang issues. Along with it cutting power when I try to accelerate up hills. The car is fun and totally driveable, but it can be annoying when I try to blip the engine and only get a little response. I'm considering going for the holley ecu since it now supports DI, just to get away from the complexity of the stock ecu. Heres the dyno, stock L83 with camaro headers and intake.

Maybe its time for an update. Car is doing well, mostly working on less noticeable things. The transmission I had was completely shot. Most gears anywhere near the synchros were pretty worn. With the price of replacement parts for the T56 lately I decided I might as well just buy a new magnum for slightly more. With the engine still mounted forward from other LS swaps, the F-body shifter was a bit too far forward compared to the GTO shifter. The GTO shifter was also just slightly too far back in its original location where 4th gear would hit the console trim. It looks a little sketchy, but I was able to drill new holes and flatten out some features in the GTO shifter to match the magnum shift cup and seal correctly. Original holes were plugged. I also welded on the bad dog frame rails over my existing rails. The rails weren't terrible, but had a couple bad spots that I wasn't totally comfortable with. I installed the 240z e-brake cable in as well. Welding on some washers to work with the larger 280z mounting points. To match the new engine, I installed some 300zxt cv axles that I found for cheap a few years ago. Since mtnickles adapter plates that don't add any extra hub thickness are no longer available I had some machined using a similar design. Also replaced the wheel bearings while I had things taken apart. The silvermine rear brake calipers are a fairly tight fit around the cv axles. I had to bend the e brake mounting point to avoid the flange. The sway bar was also a tight fit. I had originally purchased the T3 rear sway bar but it had no chance of fitting with this setup. The ST suspension rear mount sway bar fits with the spacer on the end link shortened. Swapped in some GTR AP3 side mirrors while I was waiting for the CV adapters to be machined. The ones on the car when I purchased it were some cheap plastic and tended to fall over if I looked at them. Back to some genV related stuff. I didn't have a clutch sensor wired in and apparently the ECU needs to see it. Helps to avoid the ecu getting confused when the load suddenly disappears. GenV engines seem to use a position sensor rather than a switch, not sure why. Engine is running fairly well now on a 2017 Camaro OS. Still have some rev hang issues and needs general tuning, but totally driveable. A lastly I made an airbox for my intake as I try to get things ready for some dyno tuning. First time making a fairly complicated shape from a cardboard template cutout, fairly pleased with the results.

I also used the vue setup with the bruno box, and my dad uses one of the toyota ones in failsafe mode. We both used bits of the original column though. Both seem to work fine, with the toyota one just not being adjustable, but the failsafe assist seems to be about right anyway. The vue seems to be a little biased to make turning right easier than left, but there is trims on the control box to fix it if it ever was enough to bother. The lack of self centering has never really bothered me either.

One last thing, the hood just barely fits, but probably wouldn't without modifying the engine mount to let it sit lower. Maybe if the engine was further back it might be ok, but that would still require modifying the vacuum pump flange or the engine mounts to allow the engine to move back further on the mounts. The aluminum foil on top of the throttle body is the room I had left. You can see the foil in a couple other spots was pretty close as well. I had to rotate one of the intake pipe hose clamps as it was just barely touching the hood.
