240zJJR Posted October 29, 2018 Author Share Posted October 29, 2018 (edited) My good friend Andrew @diesel.media put this killer Hell-Z introduction together as we trial fit the 6.2ltr Hellcat motor in my Datsun 240z. Hope you enjoy!!!! https://www.youtube.com/watch?v=PCPfHHMaQ64 Edited November 16, 2018 by 240zJJR Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted October 29, 2018 Share Posted October 29, 2018 That's crazy, in a good way. What are you planning for chassis strengthening? Quote Link to comment Share on other sites More sharing options...

When I get back from my first ever trip to Sema. Motor will be removed and the car will be getting all braced up. I have ordered new floor pans from Charlie at Zedd findings. I will also be building a full chassis. I have not come up with my exact thickness or widths (need to measure that out)....but plan on using 1x2.5 or 3" under the chassis and something super close in size to the existing engine frame rails. We will be tying it all in with a full cage. Need as much strength as possible for this twist monster motor. LOL Quote Link to comment Share on other sites More sharing options...
Max_S Posted November 5, 2018 Share Posted November 5, 2018 So...something like Chris' V10 build? Body panels on a custom frame? Quote Link to comment Share on other sites More sharing options...

I will be removing the frame rails from the front and carrying a full frame from front to back. I will also be tying in the cage for extra strength. Chris's car was pretty awesome. had the pleasure of spending some time chatting with him in Vegas. Jeff Quote Link to comment Share on other sites More sharing options...

My car had to be clipped in front of the strut towers due to a previous hack repair job. We discovered that the frame rails had been covered with body filler to hide the wrinkles so new frame rails were in order too. We removed the frame rails and replaced them with 2 1/2" x 2 1/2" square tube which was close in size to the factory ones and then took 1x3 tube steel under the floors and tied them to the rear factory subframe. The 1x3's add a fair amount of strength and give you some much needed jack points instead of the factory ones that are always crushed. The challenge was mating the 1x3 & 2 1/2" tube together at the base of the firewall. I believe that structurally it's sound but not the prettiest joint. You have to be under the car to see it. We removed the factory core support and put in a simple bolted one but I know it's weaker torsionally than the factory unit. I never finished the car and it's tucked away in storage right now but when I get back to it I'm probably going to go with a braced welded in unit. Here are some pics to see what was done and just food for thought. Added a plate as a gusset and TC bucket tie in. I did media blast every square inch and apply some good epoxy primer before the body work started. Should have done that before the metal work. Engine compartment all smoothed out and ready for color. Edited November 5, 2018 by Jeff Quote Link to comment Share on other sites More sharing options...

I am actually starting on it this week. My first thing is to brace the engine bay and the inside of the car so i have no movement. I was going to put it back on the rotisserie, start with new floor pans and rails. I will then take it off the rotisserie to level the car and start on the front rails. I have been trying to find pictures on bracing the whole car before I start... Engine bay i om ok with...just need to figure out how to brace the interior properly.

rturbo 930 Posted November 7, 2018 Share Posted November 7, 2018 If this is going to be a street car, you may want to rethink a full cage, there's a number of posts on here on why a full cage in a street car is dangerous. 74_5.0L_Z built a cage without a pillar/roof bars when he rebuilt his Z with a tube frame, and would be a good example of how to stiffen and reinforce the car without the issues of a full cage.

I did the front frame rails first with it on the ground and no bracing. We hung doors, fenders and hood back on it and everything lined up great, no worries. I then put it on the rotisserie, put the 1x3 frame rails in, cut out the floors & replaced one side at the time. Did all of that without any bracing and I paid a big price. The body shop was pretty far into it before they hung the fenders and hood again only to discover that the front of the drivers frame rail was 1 1/2" higher than the passenger side. It had to be put on a frame table and pulled back into shape but the good news is I now know it's square and straight. That was a costly lesson, so yes make sure you brace yours well. I would cross brace the interior from the front edge of the inner rocker to the opposite strut tower but hopefully someone that has actually done it will chime in.

This is what I did to the inside of the body so far . Bracing the engine bay tonight. Want to install custom oil pan as well before I pull the motor one last time before all my metal work!!!
