There are only a few turbo classes in comp. for full bodied vehicles. Here is the one that "fits".

The info. below is cut and pasted from the rule book:

AA/AT: 5.90 or more pounds per cubic inch. Turbocharged;
V-8 only; 1,500-pound minimum

All heads must be NHRA-accepted, two valves per cylinder, OEM
casting (no billet) with OEM number cast into head.
Methanol permitted in AA/AT.

Air-to-air or water-to-air intercooler permitted on turbocharged
vehicles. Maximum ... two turbochargers...

TRANSMISSION, Automatic:Permitted in AA/AT

TRANSMISSION, Manual: Permitted in AA/AT

BODY, Full-Bodied Cars: Must have coupe, sedan, pickup truck, or convertible body
commercially available, NHRA accepted.

With a 325 cid engine the minimum weight is 1920 lbs..
The index is a 7.04 and the national record is currently at a minumum of 6.64.
