600ZX

I picked this up cheap - 94 N/A with a bad engine



I have a LS six liter I am going to try to squeeze in

Great project! Please keep us updated on your work. The more fotos the better - we love the input.

Where did you get the LS?

600ZX

It is out of a Cadillac Escalade I put a mild cam in it last year. It makes between 470-490 horsepower.

Damn. Will that fit!? They like moulded the bay around the v6.

There have already been LS Z32 builds, so it must fit somehow. Excited to see one as it unfolds though.

600ZX

Actually, the LS is narrower than the 3.0! But with one extra cylinder on each bank, it is longer front to back. I am going to take some measurements and do some test fits. Electric fans could save me an inch or two.

600ZX

Just a quick check to see the clearances.

I do like this.

For the HP level this motor is capable of, it needs a massive fuel supply. The stock dual-sump tank and the complicated stock pump and transfer setup is not going to work.

I removed the stock fuel system and am putting a 15 gallon cell in where the spare tire used to go .

600ZX

Here is what I have been doing:

I removed the entire factory fuel system, re plumbed the car with 1/2 inch SS line, and installed the fuel pump and regulator, and return line. Remember this beast will be carbureted.

I also welded in a steel partition right where the hatch glass ends. It looks black in the pic because I covered the "trunk" area with some liquid bedliner I had from an old project.

To make this swap even MORE COMPLICATED - I am doing an auto to manual swap. I have the pedal assembly and the clutch master installed, and I picked up a 90-96 Nissan 5 speed tranny. I also got a slave cylinder and think I have the plumbing all set.

I had to cut down the brake pedal for the clutch pedal to clear.

600ZX

I'm working on fabricating some motor mounts and a trans mount. This is an extreme budget build, I cant be dumping thousands into this thing.

I had to shell out $500 for this LOJ (Lion of Judah) flywheel - it helps with the GM LS to Nissan tranny issue:

600ZX

I'm also painting it (in my garage) because I just don't have enough to do!!!

600ZX

Anyone notice anything missing from that rear quarter?

Skully

Tenna...Wow that's some great progress, really cool. I know sometimes it happens, but please don't run out of funds and not finish and part everything out haha. Paint looks good, are you doing the roller thing, or what are you spraying with?

600ZX

yeah - doing the roller thing

Is that a carburetor? I feel like an EFI conversion would lower the overall profile enough to get away with the stock hood, but cool man. I've played around with the thought of a smooth reverse hood scoop on a Z32, it could be pretty nice actually. Just add some height to the current "bump" and open it up at the windshield.

600ZX

Yeah, EFI would be lower, but with the oil pan I'm using there would probably be clearance issues anyway.

I'm on a tight budget, and I already had the carb and the intake so.......

Rupe

If it ain't broke don't fix it

600ZX

The engine is in and I flipped the trans crossmember around and with slight modification it works. I have two issues right now, driver's side header and space for fans and radiator.

Just throwing this out there: I appreciate good fabrication work, but the fuel setup out of a stock Twin Turbo (i.e. replace the pump and pump computer with some used parts) would absolutely flow enough fuel for your motor and would've saved your hatch usability. The stock TT pump is hugely capable.

600ZX

Thanks for the input, however when I disassembled the fuel system I discovered that the tiny fuel lines and a fairly complex transfer setup with the two sumps was just so far from my needs.

The new engine needs low PSI and high volume and felt the Nissan system was the opposite of this.
