Auto. The factory T5 in these cars can barely handle stock power. Id have to auto swap or put a Tremec 3650 or 6060 in if I wanted to go with anything much more than I've got right now power wise. The auto in the v6 trim is the same as in the GTs, and are good to way more HP than I plan on running through this thing. These cars run 15 seconds flat stock, so theyre not as slow as most people remember v6 Mustangs being.
The Probe is manual, and yeah the GT probes are 24v Mazda motors. Not fast, but it runs pretty reliably and gets out of its own way so it DDs nice.
Gearhead: The fastest v6 S-197 car I know of was a 10.91 (maybe 10.97), on twin turbos and a 75 shot of nitrous. Stock internals as far as I know. The guy later swapped a 5.4 into his car (he blew his motor apart a few runs after he broke 10s) and still hasn't broken his V6 record with his new motor.
Thanks again for the warm welcome fellas.
