I posted it to share it. I didn't mean to diss John or this thread in anyway.

 

I agree completely... There's already a thread covering that very engine build... I don't understand the need to "share" in someone else build thread if it's not relevant.

sweet. I will take 2 please. LOL.

 

JH, please a quick synopsis of chemicals, tools, process to remove the sound deadener. thx

 

dry ice. time. hammer.
clean remnants with solvent.

 

A angel saw, some sheet metal and a welding machine, that's the quickest way

 

Too boss

 

Easiest way to do it.

 

^^^agreed.

 

Screwdriver, hammer, angle grinder with wire wheel, took about 4 hours. Couldn't find any dry ice locally quick, so I went ahead and did it the simple labor intensive way.



Did some more work on the car, made some adapter plates to mount the sparco seat onto the stock rail for the drivers side. Took way too long to make, but fit and work perfectly.




Also removed some crap from the car and a part of the inner shell on the a-pillar. Even though the seating position is a little bit lower than stock I found that there was very little room between my head and the rollcage. Add in some foam and a helmet and there wouldn't be any room at all. So I took out a piece, this way I can tuck the rollcage in there and get about 2" more headroom.




Also did some work on the rollcage, Building a 6-point rollcage with some reinforcing bars here and there

 

how tall are you?

Lloyd

 

Cage looks nice and tucked.

 

6 ft 1 in


Thanks, I took my time making sure the bends were ok so the entire rollcage sits against the shell. I fully welded the main cage to the shell today, because it was so tight I didn't need to use a lot of gussets, I could just stickweld the cage directly to the chassis in most places. I think this will really help making everything stiff, since gussets can flex. I also added some tubes, more will follow soon.

 

Stick weld eh? haha

 

Stickweld? :-)
You mean MMA Arc-welding?

In swedish we say "pinnsvets", and with a very direct translate it would be "stickweld" :-)

 

Haha no, it was a typo, I meant stitchwelding :-) The biggest part of the cage is mig welded, I used tig for the gussets.

 

LOL, darn correct!

 

That's a real nice job on the cage. Nice e30 back there too...

 

wow, this is soo crazy, beautiful work!

 

"I'm not going to do anything outrageous with the chassis, just make sure the suspension and everything is in good condition, maybe remove some of the interior like the back seat's you can't use anyway but that's about it."
lol you said this at the start and look where it is now...
great thread btw I cant wait to see it when its all together

 

Thanks! That e30 is my daily driver, hugely underpowered but still a great car


Haha yeah I know, it sortoff got a bit out of control I think the end result will be better though


Made some more progress, a few pictures of what has been done to the car:

More tubes have been added to the cage, still not done though. I'll have to wait for more seamless tubing to show up before I can finish it







Modified the sunroof. I like having a sunroof so I didn't just want to weld it shut, but I couldn't use the normal opening mechanism either because of the rollcage. I ended up making it removable.





Mounting frame for the passanger seat, this took way too long to make, but fits and works well



Welded some unused holes shut



Removed everything in the engine bay






Now I need to finish the rollcage, when that's done everything can be prepped for paint.

 

Damn i was recently in a accident in my rx7 and following your build makes me feel better about deciding to rebuild i just wish you where closer to me so you could give me a hand!! Haha

 

Awesome

 

How thick was the plate that you used to build the boxes at the bottom of the main hoop? I've seen a number of cage builders weld thicker steel plates to the unibody in a couple planes to distribute any loading from the cage to the unibody better so that in the event of a roll or similar, the leg of the cage doesn't just locally deform or punch through the stock body. If you're planning on tracking the car, and with the superb quality of your work, its not a bad thing to consider (if you haven't already - and you probably have)


For example: Matt Powers 2012 Formula D ride Part 2

Keep it up!

 

All the mounting points where the cage is mounted to the shell either have a box or a plate to spread the load, both the boxes and plates are made out of 3mm thick material, which is the same as the tubing thickness. That cage in the link you posted looks amazing, I'll have to make a few more to be able to make a cage like that but for my first one I think it came out alright. It's almost finished now, doorbars and backstays are in place , Just a few more things to do before I can start prepping the car for the paint I ordered today
