Does any one know of a good place or person that will install a quality 8 point or so roll cage in my '89 CRX?

In the WNY Area!
I only have a 1 3/4" die… but I wouldn’t mind buying a 1 5/8" or 1 1/2"…
If I can get Jonny Montrose to weld it, I’d bend, notch and fit it…
Leaving interior in or metal?
Check S&W for pre bent tubes to save some cash. Mine is 199$
fairgentleman Z,
Would like to keep the interior in, but have already cute some here and there to get strut bar in and other stuff, so not worried about missing it up. I have had most of it out and would like to replace the carpet anyway, maybe down the line go full metal but i like to DD it in the summer. What would be an estimated price, ballpark?
And thanks for the info robftw, I’ll have to check it out.
Make sure you check the rules for the sanctioning body you plan to run with before you even pick up a tool.
First what sanctioning body? I am most familiar with SCCA, NASA, Chump and LeMons road racing style roll cages.
I like this site for ballparks: http://www.izzyscustomcages.com/cages.html

That 8 point cage is VERY basic. (although I see a lot of 6 point roll bars on nyspeed that people call cages)
I personally like NASCAR door bars as it adds more interior room. Do you want the passenger protected as well as the driver?
This site also has some good pictures: http://rollcageguy.com/

i need one in the mustang as long as we are on the subject. not to hijack

Thanks for all the links,
Yes, I would like to protect the passenger as this is a Father/son project into SCCA road racing. It would be nice to have door bars to be removable for daily driving, but not necessary. The CRX has been fun but time to take it to the next level, along with a rebuild of the b18c engine and tranny.
Then find someone who is familiar and does cages for SCCA type racing. Don’t go to someone who does only drag race cages
If your targeting SCCA club racing get familar with their rules
http://www.scca.com/clubracing/content.cfm?cid=44472
You can find all the scca specs for rollcages in their rulebook
You can have bolt in elements or complete bolt in cage for SCCA. Generic bolt in kits have too many compromises, bolt in has added weight of sleeves, and hardware, mounting plates don’t tie into the chassis as well as a welded plate.
The reason that you would want a NASCAR style door bar for the doors is that under the rules this allows you to gut the door (for weight reduction). Bolt in door bars is possible, however, you will still have the male part of the sleeves attached to the A-pillar front down bars and to the main roll hoop. The other consideration is that the door bars should be tied in together with vertical members, this will reduce the tolerance to bolt in and line up the sleeves as you would have to line up four sleeves per door. (In other words it will be a pain in the ass getting everything to line up just right for a really well built door bar)
Best case would be a sill bar, and then a low door bar (with vertical members), and then a removable upper door bar without vertical members. This wouldn’t be the absolute safest, but it would meet the letter of the rules.
You should also consider getting the front down bars as close to the fire wall as possible, this means that you will have to lightly modify the dash. You have to leave the dash in for SCCA IT classing.
Building the cage with a passenger in mind isn’t that much more difficult, just that you want to mirror the door bars (where as if it were a “driver only” cage you can get lazy with extra gusseting and extra points on the passenger side). The main hoop will have an “X” instead of a single diagonal, and then there would be two recessed harness bars instead of one. Having a single diagonal does allow some flexibility in mounting the driver seat though.
I will read over the SCCA cage rules when I get time, but based on your engine choice I would recommend building your car to fit NASA rules where it will have a chance to be competitive. This may mean you can remove the dash completely. You can still run SCCA in a NASA “classed” car.
So if you went with the traditional sleeve you would have this:
However, on pdf page 123 and 124 (GCR - 118 and 119) these are acceptable alternatives to a sleeve:

This is the simplest illustration(s) on how to design a bare bones cage:

I have looked at the NASA web site and I think you have really sound advice. It sounds like it will be better for the set up I already have in the car to prep it for NASA since it sounds like they have classes based on weight to power ratio, than manufacture items and such in SCCA classes. To be honest I do not know much at all of NASA or SCCA for that matter. Thanks for all the help, keep it coming. I’m hoping to be able to start prep for the roll cage in May, by then the funds will be up also.
Yeah, I wasn’t sure if NASA still had Honda Challenge or not, but they do: http://www.nasaproracing.com/rules/Honda-Challenge.pdf
You don’t need to manufacture anything for SCCA, I am confused by that statement. In Improved Touring you have to keep the stock D series and stock transmission (which isn’t attractive to most people).
NASA is much more friendly for people that want to modify their own way and not by the way a rulebook dictates.
That is what I was trying to say, needing it mostly stock in the SCCA, so yeah agree with you whole statement. NASA looks like a good place to start, my CRX has a GSR motor, tranny, wire harness, gauge cluster, brakes and suspension(basically the same anyway). Not going back to stock!
Along these lines, you should make sure there are people actually competing in the class youre in. I don’t know how long it would be fun to always place first.
The first race off of the top of my head from 2012:
http://www.mylaps.com/results/showrun.jsp?id=2341787&perclass=1
7 cars in ITC, 18 cars on track at the same time. On that subject, let me know when either of you beat the ITC’s 1:21.838 @ Nelson in w2w, official race results only (in either a CRX w/ a GSR or a Spec Miata prepared beyond SM rules)… not saying that it can’t be done… just curious to revisit this “challenge” when it does happen.
