Sirpent Posted February 4, 2019 Author Posted February 4, 2019 Dry or wet weight David? Being a 240z they are lighter than the 260’s and that iron L6 being replaced by alloy would also help Ive got 35kg in the ladder chassis, will be another 8kg in those rails, lpg donut tank a good 5kg extra the diff will have another 3kg extra, AMG seats another 10kg, planned rear inner interior mods and reo probably 10kg Thats 70kg just there on top of the original 1,100 kg 260 wet weight Quote
KatoKid Posted February 4, 2019 Posted February 4, 2019 Semi dry or wet depends on how you look at it....glass half full? 1080 kg was the weight with what ever was in the fuel tank which wasn't much so call it dry. M3 engine is still an iron block. Internets says that M3 engine is only a few kg's heavier than L 6, but I've got R200, and Skyline brakes which are much heavier so STD 240Z weight of 1045 plus my add ons makes 1080 seem spot on.

Sirpent Posted February 9, 2019 Author Posted February 9, 2019 Notched out the roll bar area and added and RHS section for streangth due to its now dog leg shape The front graft welded up brilliantly and as the new rail section is securely welded to the remains of the lower torsion rod mount I don’t think I will have to plate it with a gusset to reinforce it, it’s now purely more of an asthetic section. Still needs finishing welds which I’ll do later. Now onto the second rail and removal of the remaining floor pan. Happy days. E783ED2F-1A20-4AE7-AB85-1EDD3854A36F.MOV Enzo and CBR Jeff 2 Quote

Sirpent Posted February 9, 2019 Author Posted February 9, 2019 Thanks Buddy i need to catch up to you Quote
Sirpent Posted February 10, 2019 Author Posted February 10, 2019 Rail #2 underway Removed drivers floor pan, de-spotted and cleared all the overlap metal to adjoining sill, front firewall and rear bulkhead the remaining tunnel section with the reinforcement will also be removed and replaced along with a new horse shoe reinforcement. Photos unfortunately don’t load in correct sequence KatoKid 1 Quote
Sirpent Posted February 16, 2019 Author Posted February 16, 2019 Progress on drivers side rail today with attention on the rear dog leg extension All in all going well, checking the geometry, I ran a length across them both and then measured the distance from each sill, each side has a gap of 53mm and are squared and level. Hopefully I will get the chance to finish this one off tomorrow before I move onto the floor pan and trans tunnel. 260DET 1 Quote
CBR Jeff Posted February 22, 2019 Posted February 22, 2019 (edited) Great work John. It’s a very strong platform to bolt the big banger to. Thumbs up. Jeff Edited February 22, 2019 by CBR Jeff Quote
peter t Posted February 22, 2019 Posted February 22, 2019 Good to see progress John. Are you going to cage the car as those rails will have no crumple factor? Quote
Sirpent Posted February 22, 2019 Author Posted February 22, 2019 Thanks Jeff Yes should adequatodeal with the M112’s torque or a future addition of 2 more cylinders in the M156 AMG V8 which is identical as far as transmission bolt pattern and engine mounts just a fraction longer Quote

Thanks Peter Crumple points have to be added fore and aft on each side of the engine cross member still No internal roll bars planned, but a reinforcing ladder brace between the two rear shock towers is in the plan Quote

Sirpent Posted March 2, 2019 Author Posted March 2, 2019 Nice to be back Simon Another day of fabrication removing the remaining tunnel section and fabricating a new cross support. After centering all up I realized that the entire sections are not symmetrical and are off some 15mm to the passenger side, meaning the drivers foot well and gearshift position are 15mm more to the left. All good, I’m having new custom pans cut, bent and pressed which should be ready this week. Happt to report, no exploding cutting discs and flying metal this week. Cheers John Quote
Sirpent Posted March 3, 2019 Author Posted March 3, 2019 Well that’s it for the weekend Ran out of gas as I was finishing off the gussets in the rail floor pan cross member Managed to weld in the ladder chassis pick up bolts, close the ends after reducing the deck height by 5mm and welding one gusset in All in all, extremely happy with the progress Quote
CBR Jeff Posted March 3, 2019 Posted March 3, 2019 Nice work as always John. It’s a pain how Murphy comes along and slows things down just when you have a role on. Jeff Sirpent 1 Quote
Sirpent Posted March 9, 2019 Author Posted March 9, 2019 Well that’s the second rail in and blended front and rear into the body along with the (What I’m calling) the tunnel horse show with ladder chassis bolt points Now for the pans which are almost ready to pick up along with some additional weld clean ups cheers John Quote

Sirpent Posted March 10, 2019 Author Posted March 10, 2019 Time on the rotisserie today making a new lock mechanism Cars upright now ready the pans Quote
Sirpent Posted March 11, 2019 Author Posted March 11, 2019 That’s all she wrote for this long weekend Added some additional gussets at the horse shoe and sat the rare spares pan in just to get an idea how all will sit with the new pans on order and am satisfied all will line up exceptionally well Quote
