From Appendix A of the rulebook, here's some stuff that seems relevant.
D Modified (DM) - under 2.0L
Min weight 1280lbs (<= 1.8L) / 1380lbs >1.8L - 2.0L
E Modified (EM)
Min weight 1700lbs (<= 3.2L OHC, 4.5L pushrod) / unlimited displacement - 1800 lbs
and -
Turbocharged or supercharged versions of the above engines will be classified at 1.4x displacement.
---
So a non-turbo car is probably best in DM running as little weight as possible, and a turbo or big NA motor goes to DM.

Yep. N/A miata or K swap (K20 seems like the hot ticket) into DM.
V6, V8, Turbo swap into EM. The weights include driver, so the 4cyl turbo guys will be right at minimum weight in EM, which is good. I expect my V8 car to be about 100# over with my big butt in the seat.

Also, some important points to be fully mod legal (in case your region likes to protest or you're going to attend a national event):
1) Master Switch: All cars shall be equipped with a master switch easily accessible
from outside the car. Club Racing Spec Racer Ford vehicles shall
be wired per RFSRII. The master switch shall be installed directly in either
battery cable and shall cut all electrical circuits but not an on-board
fire system if so equipped. It shall be clearly marked by the international
marking of a spark in a blue triangle and mounted in a standard location.
2) Driveshaft Hoop: RWD DM and EM vehicles shall have a driveshaft hoop
capable of preventing the shaft from entering the driver’s compartment or
damaging any fluid or electrical lines in the event of joint or shaft breakage.
All cars in competition using open driveshafts must have a retainer
loop with 360° of enclosure, ¼ inch (0.250”; 6.35 mm) minimum thickness
and 2.0” (50.8 mm) wide, or ⅞ inch (0.875”) x 0.065” (22.23 mm
x 1.65 mm) welded steel tubing, securely mounted and located so as to
support and contain the driveshaft in event of U-joint failure. Vehicles that
have a closed “tunnel” or other such structure which the driveshaft passes
through such as the vehicle’s frame, may be considered for an exemption
from the SEB if that structure meets the criteria stated above
You are exempt from those two requirements if you're running DOT approved tires. AFAIK, we have not been granted an exemption for a driveshaft hoop, but I'm not 100% on that.

We don't have a tunnel, no reason to expect an exemption. I have both of those items on my car. The hoop is a big deal for anyone making real HP, driveshaft can tear you apart as well as the car.

D/E mod is more or less unlimited other then weight and no aero. I run autox wingless.

Thanks for clarifying that dietcoke .. really too bad we can't run with the pretty wings in D/E M.  |

Just saw what "we" are up against at the National level in E Mod. What a monster .. what chance does an exocet have against that thing ? Zero IMO. He is permitted aero and also have an intake tube for a passenger FFS!   |

You can build the same silly airdam on the back of an exocet, just fyi. To be competitive at the national level you're going to need at least 350-400hp in an exo IMO. My car is faster then that green thing in a straight line, though his may outcorner me (and he's certainly a much better driver)

For modified, SCCA allows for static aero devices .. normally. But specifically says no functional wings or tunnel for the Exo .. Does that 'airdam' not count as wing or tunnel ? Keep in mind you're talking to a non engineering layman.  |

No, airdams don't count as wings. You can build the dam 10 inches off the highest part of the bodywork and extend it all the way out to the widest part of the rear fender, and enclose all of the space in between.
Per the SCCA rules, a "wing" has air pass under it - it must be in open air. Spoilers are allowed, which is what the airdam is.

You have to take into account the green car above has been developed to fit into the class rules. All national level cars have been built around the letter of the rules. With the right parts and development time a Exocet could be competitive but it's a new chassis with no one really trying to build one to that level yet. I think with the right driver and development time you could get there.

Yeah .. the more I look into that car, the more I realize its a bit silly it is for me to hope to beat a trailer queen that's been developed for years and years with a street driven Exo .. even one with 350HP .  Its going to take quite a bit of money to get in even striking range of that goal .. not to mention a hero driver ( which I'm not ). |
