This is my 1966 L520.

The project will result in one Bad Ass Datto Track Truck!

I'm an avid road racer. I am also a Datsun pick up NUT:eek: Put the two together and you get to look into the twisted mind of Bob. My project is a combo of a 1966 L520 & a 1990 Mazda Miata (MX5).

So far I've removed the Datsun: engine / trans / steering gear / front and rear suspension down to the bare frame.

Here are some pics of what I've done so far.

I had to do a little frame work to get the MX5 sub-frame to fit.

Here is the sub-frame modified and ready for its new home

Here is my 520 sitting on independent suspension with four wheel discs and 17's

Well - What do you think?

I still need to finish up the rear. It's just sitting on the sub-frame now. After I get it attached, I then need to fab up shock mounts both front and rear. It shouldn't be too tough. It will be cool once it's sitting on the coil overs

I'll post more pics as I get more done.

Its almost criminal. I can't even look at that car without crying. Having seen her in person, I can only say that if you were in a car like my Corolla, and this happened, you would be making funeral arrangements for your buddy. The damn car saved your life, without a doubt. You put your heart and soul into that car, and she gave hers for you and your friend. Take comfort in that.

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

I already have a barn full of VW parts that started just like this. I should have taken up stamp collecting instead of lying on my back getting greasy. Thanks guys,

That is pretty cool! What's your take on the suspension angles? Could you have moved the subframes even higher, or channeled them from the sides, to get the arms in a downward angle?

I have not yet begun to defile myself.

As far as suspension angles go, I have figured it out based on our Spec Miata Race Car. The arms are not designed to be run in a downward angle. In fact, the 520 arms are not angled up as far as the race car.

Posted Image

This is our Spec Miata driven by my son Tommy at Mid Ohio Sports Car Course. It weighs 2475lbs ( by rule minimum ). We run the subframe clearance at 4 inches. The weight balance is 52% front / 48% rear. I have the Datsun 520 set at 5.25 inch clearance and I figure it will weigh around 2300lbs when I'm done. With ballast I think I can get the balance close to 50/50! It should be alot of fun:D The best part for me is there are no rules to keep me from changing spring rates and using stiffer swaybars. This thing is going to handle AWESOME!

Awesome. Sounds like you have a good idea what you're doing

Any plans for the motor? Looks like a good amount of room for piping *cough*

The increased wheelbase should make it more stable in the straights too... AWESOME build, even without the nissan motor... although you can now do an easy rotory swap!!

My hat is off to you! That is completely awesome!!! More pics please!

How did you deal with the top of the shock mounts....or are you converting to shorter shocks?

Don't have to be too bright to be me!! :D

I got one word for you Bob...

Oh...and I call dibs on the next one.

What is the horsepower difference from the stock motor to the Miata?

What do you think the difference will be from my gently massaged L16?

See you soon man. :cool:

Anyone else out there got a Simca?

I plan to tackle the front shock mounts this weekend. They shouldn't be too tough. The rear is looking to be a bit of a challenge. I may be looking at some custom rear shocks? We'll see. I'll try and get some more pics up this weekend as the project continues! It is alot of fun!

See you soon man.

The motor I'm using to get it all sorted out should be around 115hp at the wheels. I plan to install a "better" motor in the spring that should put 135hp to the wheels! :eek: I don't know what the hp is for the stock 1300cc L520 motor. I know that the 5 speed trans will sure be nice.

I'll be out in the shop tinkering this weekend if your bored.
