Engine and chassis swap datsun 260z in S30 Series - 240z, 260z, 280z Posted Sunday at 09:04 PM I'd like to see more dedicated tube-chassis and other radical mods. Whatever happened to jos260z's project? Promising start, but then...? One approach is to build a proper round-tube chassis on a jig, with the desired front/rear subframes (or even better, mount the suspension directly to the chassis, eliding subframes and their associated weight). Hollow-out (technical term?) the Datsun body, and then wrap it onto the chassis. This has been done before, but recent examples are hard to come by. In the 90s there were some drag racers... the name Ron Jones comes to mind. Ron used to post heavily here, then drifted away. That car, if memory serves, used the stock 240Z front suspension pick-up points (including K-member) and a fiberglass front clip (hood, valence panel, fenders and "bumper"). In back was the obligatory tubbing, 4-link and Ford 9". The salient question is of course why one would do this, apart from the tackling of a challenge and the desire for originality. One answer is weight reduction and stiffness-increase for drag racing. Dedicated drag-cars tend to converge towards one common solution. The "bones" are all one triangulated tube frame, and the body amounts to the aforementioned wrapping, be it a Datsun or a Chevelle or a Fiat Topolino. I'd also like to see more cars with firewall setback. Put the largest and heaviest component of the car further aft... that is, the engine. Zs are famous for their enormous passenger-cabin. With the seatback securely pressed against the rear tire-well (stock or tubbed), there is plenty of room for setting the firewall aft. Why go to all the trouble of a tube chassis, if retaining the stock location of the principal components? Get creative!
