Anyone have a picture of their trans tunnel after they clearanced it to fit the 4l80e?

No pics yet. But I realize I have to make room for trans cooling lines and wire harness connector

 

I have to do the same. I have the tranny under the car right now, but have been focusing on other aspects of it before I cut out the factory tranny mounts.

Enjoying all the great info. I have a 79 280zx going through a 5.3 ls/4l80e swap right now. Just getting started. Has a Ls4 intake I snagged complete out of a parts yard, with adapter plate for 5.3 throttle body. Later on I'll  look into a ls1 or ls6 intake. Eventually will be a 6 speed T56 or CD009. Of course  I have same issues of engine placement and supporting parts being worked out.

 

 

Have a picture of the trans tunnel after massaging it to fit the tranny?

Any updates on this?

This may have sealed the deal for me wrapping mine. Just curious, what tools did you use for sanding? I will probably end up buying whatever you used.

I have made some progress on the project lately. I ended up using the transmission mounts provided in the JTR 280zx small block swap kit. I had to drill holes in the tunnel and "massage" the tunnel with a hammer. I do not have the transmission fully bolted up but the mounts are finalized and I am doing some work on the transmission itself and the engine right now. I can say that a lot of "clearance" work has to be done to the tunnel to make everything fit nicely. I may be able to get the transmission and engine mounting finalized and pictures taken this weekend. I also got my turbo this week so I will be figuring out how to mount and pipe that bad boy soon.

Just wanted to give everyone a little update on my swap progress. I got the JTR motor mounts installed, chevy smallblock to LS adaptors installed, and the engine sat in the engine bay. I need to do some adjustment to the engine position but so far everything is looking good! I am seriously toying with the idea of going turbo right away. I looked into using the truck manifolds and cutting the stock flange off and welding a Vband in its place. Does anyone have any insight on how to route exhaust in this case? I am thinking of going up-forward with the stock manifolds to the turbo and then from the turbo down the passenger's side of the block and then out. Any thoughts on this? I think that as of now, I have 2 big hurdles.  

 

1. Mounting the 4L80e I have (Not too sure how to make a mount the tunnel or to the framerails ).
2. Routing of all exhaust

 

Anyways, here are some pictures of the swap so far.

I am just going to reuse the radiator that is currently in the car, has a trans cooler in it as well apparently so I am going to try that out also for the 4l80e. Should have the old engine pulled tonight/tomorrow morning, then I will be dropping the 5.3 and 4l80e into it and getting things wired / buttoned up.

Also, what are yall doing with your gauge cluster? I am trying to think up ideas on what to put in place of the stock datsun cluster because that won't be any good with the gm ecu.

I have what seems to be a decent size alum rad currently in mine. Just need to rip the engine out w/ the belt driven fan and figure out what size fan/shroud I can mount to it.

 

 

For those running fuel cells? Which one did you go with? I am not sure if I want to use the stock datsun tank still or just run a 15gal fuel cell in the back with a sump and external pump.

What radiator / fans are yall going with?

[280zx's with Ls swaps]

In for the same info. I am assuming the OEM GM LM7 pan wont work. Thing seem pretty long.

[280zx's with Ls swaps]

Great thread. Awesome info here. I will be doing an 5.3 swap on my 1980 280zx in the near future. Just trying to gather all the info I need before hand. 

 

Anymore updates Subhuman? Your build is coming along great.
