I searched this way and that, but didn't find anyone who put an L6 into a 300zx. I've seen the L6 post into the 240sx, but was wondering why not into a 300zx.

I'm looking at a 300zx turbo w/ a blown motor and was curious if you could go V6 to L6?

Could the stock 300zx wiring and electronics be used to run the L6? Issues w/ firing order? Fitment?

Physically, I don't see why not. There is an RB Z-31 running around that is stupid quick.
Regarding the firing order, the EFI wont care what the firing order is. The old EFI is batch fire, i.e. all the injectors open and close at the exact same time.

Nissan ran the L28 in the z32 in some class of racing in the 90s. Was restricted to 2800cc and under for the class. Will see if I can dig up some more info.

Thanks guys. I've not seen this reverse swap. I'm checking out the car tomorrow. I'm hoping it is at least a real 87 Turbo for the rear end alone.

It's started out as $1500 car w/ a blown motor and now down to $500, will see.

Yes I've seen this via searching, just not anyone who actually installed an older L6 into a 300zx.

Thanks though.

Good to know. The timing belt broke. Most likely a few bent valves.

Z1 Motorsports, in the Atlanta area had, a 300zx with an L6 installed. It was a customer's car and it had been stored there for some time. It was a full caged, race car that I was told, had come from Canada. It was a very interesting car and may have been a stroker due to the high, fast reving sound of it. Too bad I didn't get some pictures.
Driving Fast...........
What does it take to make a fast car go faster?
Anyone with a strong right foot can do it. Most likely, in the instant before the car crashes, it will be going quite fast. There is more to driving than FAST. Getting around a course QUICKLY requires talent. It means pushing a car to its very limit—and sometimes beyond —while avoiding the crash, the spin, the bobble that nixes the entire effort. This is ART.(unknown author )

For all the trouble its worth, why not get a VG which are cheap and swap everything over from the blown motor (manifolds, turbo etc), then you don't have to fart around with custom engine mounts etc?

The VG33 from the the Pathfinder Truck would be cool..

A buddy of mine in high school had a New, very early 84 300z. It had a L6 factory.
Only 1 I ever seen.

Turned out to be an 86 :( I was hoping at least 87 but the body wasn't as nice as the pics.

I think the 86 is the nicest looking year for the 300ZX, from 84 thru 96 TBH

Interestingly enough I had actually been thinking about this idea not long ago. I probably wouldn't do it, but I was figuring. I love the L28ET, it's so accessible, the Z31 body sits a little wider, has a better suspension setup, lower CD and doesn't weigh too much more than an S130. The only thing I wonder, would there be much difference in say the L28ET vs. the VG30ET. I've only had experience with my L28ET with the auto and 3.5 rear, so I'm not really sure what kind of a difference it would be with a 3.7 rear and the 5-speed. I bet it's definitely quicker.

That's a full blown race car, but interesting none the less.
