I agree. The NHRA wording is a bit of E36 M3. 
 

But this has been discussed in depth, and the GRM Challenge interpretation has been to focus on the line that says:

"the use of stock-type cast iron flywheels and/or pressure plates prohibited..."

That's why they took SFI trans shields out of the budget.

  The $500 I paid for the XJS included a brand new  Mega Squirt. Plus a few other items like a new aluminum radiator, a complete 6.0 injector set. A pre HE distributor.  And a few boxes of misc. 

The "free" set of tires will be for Autocross and I'll "rent" a pair of mounted drag slicks since I won't do the drag race again. Should be someone at the strip with a Chevy.

Ah it must be in a rule change somewhere, as the fabbed shields were allowed for all but now it only seems FWD/Transverse it is. Which makes about jack E36 M3 for sense, but typical nhra bullE36 M3. Still if the sfi shield isn't in the budget it doesn't matter and is actually "cheaper" than a fabbed one ($0) just out of pocket money needed.

There is no budget exemption for a shield.  In this area only for an SFI flywheel and harmonic balancer.

Partial Exemption: The Violet Rule (previously known as the Reese Rule): SFI-approved harmonic balancers, SFI-approved flywheels and SFI-approved flex plates are budget-neutral. These parts are dangerous rotating assemblies that should be treated with respect. Any intact harmonic balancer, flywheel, or flex plate listed on the budget may be exchanged for a duplicate SFI-approved part without increasing or decreasing the budget. “Duplicate” is defined as having the same listed application as the standard part in a major parts catalog. In situations where a standard part is not present to exchange, fair market value of the standard part may be used. SFI-approved transmission shields, SFI-approved flex plate shields, and SFI-approved bell housings are not rotating parts, and are not budget exempt. You may still be required to use one or all, depending on your car’s construction and E.T. in the drags.

It's very easy to misremember rules.  Kinda makes a fellow want to go over some budgets.

Yep. You're right. Misremembered.

I would say the flexplate/flywheel shield is more important than an sfi flywheel, but rules is rules!

I think Andrew Nelson put it best when he said stuff like that is a speed bump.  If you make that (or roll cage that comes up a lot) part of budget then the competitor can't spend that budget on going faster.  Me and this example is a perfect case study.  I'm now building to a 11 second limit because I like running half budget.  Interesting enough I've had two private conversations today about building safety to rules or building to be safe.  I like my feet attached to my body so I'll probably build a shield as you pointed out.  Won't be for NHRA rules but for my own safety.  I've said in the past that I wish tech was more involved at the Challenge to the point that they tell you or mark down what your build is good to in the 1/4 miles.  I'm sure there are some things that have snuck by in the past.

In reply to Stampie (FS) :

I guess we agree on something.   If I'm limited to a certain time in the quarter mile, then that's what I'll turn  and if I have to sand bag to keep from going faster I will.  But there doesn't  seem to be any restriction on how fast in the Autocross. So rather than buy ( rent ) a set of drag slicks and any surplus funds.  I'll try for a faster autocross time.

You and I most likely agree on a lot more than you think.  Doesn't mean I won't bust on you and your slow Jag V12.

I have both a SFI flywheel and scatter shield  but for a manual transmission.  Nothing for the current Auto trans.   I can't see even a gray area way to swap one for the other.

Oh I'm ready for you;-) I've got the excuses all lined up.  Besides I'm a Newbie. And old. And Fat,  etc.  Oops. That's wrong.  You're a Newbie, your old.  Oops that still wrong.  
Don't worry I'll have the trash talk down by the time of the challenge.

In reply to Cooter :

Here is my tentative budget for the Challenge. $500 car and I get to sell parts of it equal to 1/2 of my purchase so net $250. ( actually probable retail value many times this )  

1984 Jaguar XJS $250  

    Two T4 turbo chargers  $220. 
    Connection tubes etc $345. 
    Regrind stock camshafts  $245

    Gasket set $87  

12 used injectors  $35 

Grind valves $240 

Ethanol  sensor  $20   
fiberglass for hood, trunk lid, and door skins  $250 

 That should be about $1700. 
  Weight should be near 2700 pounds and I'll  between 400-500 hp. 
      In 1982 a Bruce Wilson went 9.710 @137 in a 1/4 mile. In a Jaguar XJS V12. 

Again the rules are at https://2000challenge.com/rules.

Looking at your list I see things you miss so let's organize.

1984 Jag XJS $500

Turbos             $220

Turbo Tubing   $345

Regrind cams  $245

Injectors              $35

Gasket set         $87

Grind Valves   $240

E85 Sensor        $20

Fiberglass       $250

Guessed total $1942

Recoup:

Jag XJS       $500

What I see missing

AutoX tires    $200   (2 exempt 2 used)

Drag tires          $0   (2 exempt)

Drag wheels    $50   (Assuming using stock wheels for Autox)

MegaSquirt   $200

Cage Tubing $200

Total Missed $650

So grand total is Guessed $1942 - Recoup $500 + Missed $650 for a Challenge budget of $2092.  No bueno.

Edited as I missed stuff but really question $35 for used Injectors.

Turns out things change.  
 For example  the cage was a little more expensive than I calculated.  But  I'll buy autocross tires for my exempt tires and pick up a pair of used drag slicks. 
   The fiberglass cost may be more or less than my guess. It depends on if everything ( resin , activator , etc  is still good etc) 

  A brand new  Mega squirt came with the car.   I won't need the Flex fuel sensor since I'll always be running E85. 
I'll see what the intake temp is  and if it's too hot I'll just squirt in some windshield washer fluid in rather than buy an intercooler. 
    Having watched Calvin Nelson use of used Atlas engines,  I won't be taking the engine apart. I've got 3 good ones. And  if the Nelson's can make 824 horsepower on an unopened Atlas of 4200 cc   (290 hp stock) I should be able to get 5-600 hp from a 5300 cc V12 without freshing  up the valves.   My local cam grinder  just raised his prices  on grinding my cams so they may remain stock
  That should get me back under the $2000. 
    I do have the option of running fenderless, without a hood or trunk lid.  So even if I'm a little over without those parts I'll squeak under the $2000 limit. 
 Thank you Stampie for going over the budget.   With regard the injectors. I was planning on buying those at the junkyard with other stuff on one of those all you can carry days.
