Wow lots of hard work going into this car. Looks what I should be doing to my project rx7, and what you should also be doing to yours! Get that widebody in mint shape! Drive it for a while, then sell it to me . hahahahahha

updates? I love seeing these builds.

Been on the back burner for a little, with basement renovations, our CL-S 6-speed swapped TL and my Widebody FB, lol. I did weld in the passenger door, I'll post pics soon. Don't worry though I cleaned up the garage just yesterday to get ready to jump in again

Mazda RX-7 EFINI TYPE

Alright ppl...bringing this back from the dead. Most of you probably forgot or thought the project was abandoned...but...the struggles goes ON! lol. Anyway, lots of changes since then. If you all recall, I had a survey up a while back about starting a shop. Me and my 3 brothers opened our own shop in London, by the name of Disciplined Tuning. We've been operational for a few months, however I haven't really opened up to the forums yet, as we are still settling in and getting everything sorted. I know a lot advised against it...but when you have a childhood dream that you are given the opportunity to make a reality, who can really stop you right? lol. At least If I don't make it, I will know I tried . Anyway, enough of that crap, let's let the pictures talk . First off...a teaser!

Sorry for the hugeness of the first few pics ...lol.

Oh man, so much work and so much time.

Just a couple of things to consider. That fuel cell isn't legal for any CASC sanctioned racing. It would be far better off just running a stock tank and filling it with cell foam. That is legal and way cheaper. Also you need bulkheads between you and anything to do with the fueling system. You just can't have all that stuff running through the car. Its freakin' dangerous. One leak and a spark and you have a pressurized flame thrower inside the car with you. Not good.

Secondly, is that cage legal? Take a look at the CASC rule book for information on bar sizes and material grades. They also have recommended spring perch mounting plate sizes, tube run locations, etc.... Lots of other things I see that are nitpicky, but overall you guys are very dedicated.

I would hate for you guys to do all this work and end up with a track car that is very limited in what you can do with it or maybe not as safe as it could be. Go to the CASC website and you can download everything you need.

Good Luck!

Thanks for the advice! The fuel cell is just sitting there right now. It will be bracketed down and completely enclosed and seperate from the cockpit. Just haven't made it that far yet, lol. Also, the cage came from an SCCA car...so...should be legal no? Also, why is the fuel cell itself illegal?

Mazda RX-7 EFINI TYPE

Eric I know practically nothing compared to you with all the technicalities and i'm sure many other things that you learn with experience. If you have any other recommendations or concerns, please msg me. Any and all help/advice is appreciated .

The Bulkhead should just go across the back of the car about where the rear seat back would go and all lines and cell should be behind it. The fuel lines should run to the front under the car for safety. The cell isn't legal unless it has the appropriate FIA Certification on it. I don't believe the RJS one is certified. It is also being mounted too high sitting above the floor pan. If you are going to continue with the cell, cut a hole in the floor, weld up a protective cradle underneath and drop the cell through the floor to rest on the cradle. The top of the cell should be flush with the floor in an ideal world or just slightly above. You need at least 5 inches of total ground clearance for the cell and it has to be shielded from road debris and banging into curbings.

You can do all this or just go back to the stock tank which works well when foamed up and is totally legal in the stock position.

The cage may be legal or it may be not. Don't guess that just because it was SCCA legal it is legal today. My Cougar came with a monster cage that had been approved by SCCA Pro and run for 3 years at World Challenge races across North America. To get approved by the CASC, it needed extra side door intrusion bars, the top of the cage required full welding and the materials were allowed to be grandfathered in. All new cars now are required to meet the latest standards. Just download the rules, read them, do some measuring and go for it.

You are totally free to do what you want, but I just thought that you should know so that you guys don't build a car with extremely limited possible uses.

Eric

Mazda RX-7 EFINI TYPE

Thanks a lot Eric. Will look into those things . About the tank being lower, is that mandatory? Or do you mean for lower Centre of Gravity purposes?

23Racer

Lower for Center of Gravity Purposes.

Mazda RX-7 EFINI TYPE

K. Thought so. Thanks a bunch .

Cage= Not legal anywhere likely. I wouldn't have passed it when I was an SCCA Official.

Mazda RX-7 EFINI TYPE

Thats only one part of the cage...unless thats all it takes to tell. It was only in there for mock up purposes. It's a 6-point cage. It just didnt come with the door bars, sO we would have to add those ourselves. You could still very well be right...just saying.

The diagonal in your main hoop is the immediate problem unless it was the bar you were just mocking up. Refer to the following CASC Race Regulations (note this is the 2012 edition and it may change (not likely) a fraction for 2013) for typical Ontario standards including Solo, GT Sprints, etc. (see page 57 onward, but good to learn entire doc.)

Thanks again . I'm sure i'll be bugging you guys for more info in the future .

Been a while since I updated this:

Skunk2 70mm throttle body


Gutting the harness


Still working on the cage. Have to mess around with the "connector" pieces...since they're all drilled differently.


Talk about getting full use of a wire wheel :P


Time to run fuel line brackets


Cleaning up & painting roll cage mounting plates


Idea for fuel line bracket


TIGed and painted dual fuel line brackets


TIGed on bolts & re-painted to make installation easier (also ended up grinding bolt heads)


Getting there...


Single brackets where the lines separate going into the bay

Mazda RX-7 EFINI TYPE

Re-bar brackets in the making


Re-bar mock-up


Making my own flush mount bolts


Welding on washers to make flush mount bolts


Flush mount bolt before clean-up & paint


Re-bar brackets


Brackets run & car back on the floor

Man oh man oh man, so much work and effort. Just a couple more suggestions. I know you must have spent 400 hours making up those fuel line brackets, but the metal surrounding the braided metal of the lines is a real no no. The braided will saw away at the brackets and at some point the brackets will fail and let the line fall to the road or the edge of the bracket will saw into the braided line and open it up. I would suggest a couple of ways to tie the fuel lines up.

First way is to go to Princess Auto and purchase the tie wrap mounting brackets. These are little plastic brackets that you screw into the car's metal and they have a slot to stick a tie wrap through it. Then go get some GOOD tie wraps from a brand name and use those to locate the fuel lines.

The second way is to purchase these really cool metal locating clamp brackets. They are pretty cheap and usually used to locate brake lines. They wrap around whatever you are locating and are attached through both sides of the wrap by a single bolt. The really cool thing is that they are insulated with a rubber wrap that will protect your fuel lines and or brake lines forever. They are a very easy and good way to locate anything critical. I have them all over both of my cars.

Finally, please please go read the CASC rules on cages that Jason brought up earlier. You are spending a bunch of time on the car and I would hate to have you build the car and find out it isn't legal for anything other than open lapping or Sigma/CSCS type Time Attacks that really don't have safety rules.

On the plus side, I am really impressed with your TIG welding finesse to build those brackets. Let me know how to contact you guys as I need to get some new strut bottoms buile for my new 3 ways for my FC. I have everything mocked up, I just need to get things welded up.

Does anybody else have a tame TIG guy closer to Oakville? The work I need is simple, but it has to be good.

Regards,

Eric

Mazda RX-7 EFINI TYPE

Always love to hear from you :P. I'm aware of the SS fuel lines sawing abilities, which is why I wrapped the lines with 2-way tape (seems to work as a good rubber-like insulator) where the clamps go. Also, I just want the cage in for this year to run SIGMA & CSCS. Won't weld in til we are CASC legal. And thanks for the compliment on my welding

Easiest way is probably to just shoot me a text on my cell, but whatever is easiest for you works for me.

Mazda RX-7 EFINI TYPE

Made a couple more adjustments & mods to the brackets, made my own "alignment"/side mounting brackets (I've never liked the 2 screws with a rubber band around it) and the rear is together. I want to mess around with it a bit more but that's for next winter, good enough for now, more important things to take care of in order to make it out to the track.

Mazda RX-7 EFINI TYPE

The final product of the re-bar brackets. I ended up welding a nut on it so I could just screw in the re-bar. Also made two holes for the fuel lines to come in the car, just need grommets. Should be running soon, just sourcing a fuse box at the moment.
