Well, my past car list is way to long to list, but the modded ones are easy.
1. 1987 Thunderbird Turbo Coupe; 2.3T/T5 Manual, gutted and then some, never worked right on the track but a solid 15-second car. Seemed fast to me
2. 1986 RX-7 GSL; 13B/5-Speed, street port, header, exhaust, some other stuff, 13.8@102 with a bad 3rd gear synchro.
3. 1985 Mustang; 289/C4, 4Bbl, headers, etc. Had a 2.73 peg-leg and no converter. Fun on the highway!
4. 1988 Thunderbird Turbo Coupe; 2.3T/T5 Manual, SC50R ball-bearing turbo, rebuilt engine, WAY too much money, 14.7@93 with a 2.6 60'! Had low-14's/high-13's in it with DR's.
5. 2001 Crown 'Vic Police Interceptor; 4.6 SOHC/4R70W auto, mods in sig, just got this one in December, my daily driver, I'll be playing with it for awhile! 15.1@92 so far.
Everything else was kept stock, or very lightly modded, or else wasn't modded for racing (had some show cars and a mud truck in there).
As for the 12A FB? I dunno yet, I really have fond memories of my FC and I already have that nice V8 rumble in the 'Vic. I'll be keeping it rotary for a long time. However, if the 12A decides to fail before I have another rotary to stab in, there's a big-block 401ci AMC in the garage waiting for a home...
