Do you have the part # for that pan by chance? I'm looking into a swap on my s130 and I am trying to find what pans everyone has been using.

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

The pan is jegs 555-50229 and was $240.94. Its good quality. The down side is that it uses a remote filter. I got their easy kit which comes with everything need for the install. 

 

This pans front sump is 3/4 inch deep plus aluminum thickness. I hope this helps with your own research.

Ok guys I am using stock GM manifolds because I don't wanna run headers. So the driver side is a Caddy CTSV and the Passenger is an LS2-LS3 Vette manifold and the oil pan is the holley 302-3 turbo pan. The steering shaft is getting a u joint, The passenger side looks like it doesn't clear but it does. The stud clears the frame rail as far as height goes by an 1 1/2" also using Dingo s30 mounts and raised them by 1/2"

i used an aluminum rad from JTR. i think you would be good with any aluminum rad. they are not too expensive. and a flex a lite fan with a plastic shroud. i forget the part number but they had one that was real close to the size of my rad.it is just a large single fan with like a S-shaped blade andgallery_24014_1726_776539.jpg the shroud was nice cause it wasnt just flat sheet metal. in my eyes, the fan is just as important. i paid just over $200 for the fan. but it has never over heated yet. you might be ok with a flat sheet metal shroud if you want. but i suggest that you dont just zip tie a couple fans to the rad

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.

i try not to be the only one that chims in here but if i was doing my gas tank over i would use stock tank and modify the sending unit to except a intank fuel pump. they have nice ones now that you control the depth of it to insure you get to the bottom of the tank. i have not figured out a great setup for the fuel gauge to work properly yet. i just go by how many miles per tank i get. the gauges i made a piece of ABS plastic to fit in were the original cluster sits. and the 3 little pods except autometer smaller gauges with little mods.i go into detail what i did to my gas tank and the gauges i used on page 1

Hi guys. I went with the Jegs 20 gallon fuel cell from Jegs. I was going to try to keep the tank stock but it was sitting with fuel in it for 20 years and it was so rusty and gummy I couldn't get it clean enough. When I looked for another tank and sending unit, everywhere I looked they wanted $300 for the tank and $300 for the sending unit. When I found the Jegs fuel cell, they wanted just $300 for both tank and sending unit. So to me it was the cheaper better route. But I'm also building a GT car out of mine, so not a lot is going to stay stock anyway.

Yes the stock tanks are good..I modded the pickup and installed a walbro 255L and will be using the corvette filter regulator assembly and -6 to the rails. Damn im ready to get it on the road.

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.

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 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.

Thank you for the update. Curious to see the pics of the massaging done.

It's been a little while since an update but I do have good news. I now have the 4L80 and the 5.3 mounted in the car. After the modifications to the tunnel, everything fits very nicely. I don't have pictures right now but I will grab some soon.
