This 1971 Datsun 240Z has been seriously modified with a reinforced chassis and a drivetrain swap from a 35k-mile Nissan 350Z. We’ve never seen this swap in a Z for sale, and though we’d miss the sound and feel of the big OHC straight-6, we have to applaud this build. Find it posted just two days ago here on DatsunClassifieds.com in SoCal for $19k. Special thanks to BaT reader Jeremy W. for this submission!

The new engine seems to fit quite easily in the shot below, but it was taken with the nose off the car and an incomplete cooling system (among other parts). Still, we like that the swap could be done without modifications to the hood, so there is no external tell in the photo above.

Built by an engineering student and certified welder, the interior is completely stripped and reinforced. The car is plated for street use, but the huge Recaro seat might make backing up a bit of a chore.

We like the plastic flares and rear spoiler, and we always like Japanese cars in white.The brake system is made up of Wilwood and Tilton components, and the wheels are oversized but still seem to work with the aesthetic. Their size and brand is not mentioned.

The car is shown on track but no information is given about how it performs or what might still need work. The car seems a bit far gone for street use, but it would make a very entertaining time attack or track weekend car.
