Hello! I have a 1973 Datsun 240z that I plan on putting an 800hp 2JZ in but obviously need to work on some chassis strengthening before I rip the thing apart with that much power. Here is a short list of items I found posted by the late John Coffey himself for a streetable car: 1. Seam Weld (every sheet metal seam overlap.) 2. Bad Dog Subframe Connectors 3. Weld-In Roll Bar. 4. Welded In Rear STB. 5. Triangulated Front STB. 6. Radiator Core Support Reinforcement. 7. Transverse Link Bracing Reinforcement. 8. RT Diff Mount. 9. Tubular Seat Mounts. 10. Box Upper Frame Horns to Firewall/Cowl. 11. Reinforce Pedal Box/Brake MC Mount. 12. Reinforce Front ARB Mount. 13. Reinforce Front Strut Tower to Frame Rail Junction. I plan on doing some competitive drag racing, roll racing, track days, and driving the car around just about everywhere! I have a very clean paint job on the car and the body is nearly perfect, so repainting the car/pulling out glass isn't really something I'd like to do. However, I think pulling everything else off the car and putting it on a rotisserie would make the seam welding much easier as well as the frame rails and such and I can live with that. I would LOVE to hear from you guys that have done this and if you were able to preserve the paint and glass on the car. This is a pretty big undertaking so I'd like to prepare myself as much as possible before jumping into this huge project.
