Oh and how's the solid axle FD working out?
I've owned a auto FD, completely stock. Hold brake, floor throttle would result in wheelspin. Release brake and the car would creep away at 2500rpm without the tires spinning. Anyone launch a 5spd at 2500rpm? It doesn't move away that quickly.

I believe it. It is still pretty cold in March so you were putting out some pretty good HP due to the cold weather.
I ran a 13.1 with a DP and CB but it was only 45F outside so I figured I wouldn't count that run.
So how is the 4-link conversion coming along?

From what I've read, the torque converter is the weak link, and is why they have rev limited the auto lower than the manual. I just wonder what it could do with an appropriate "racing torque converter" (whatever that would be). BTW, we see the same thing happening now with the RX-8 (lower rev. limiting due to the torque converter).
And, ricerslayer, no, unless you have lots of money. You have to know how to drive high performance cars so as not to damage things. Things like proper warmup, watching the boost for problems that could destroy the engine, etc.

Stock 5spd is typically 13.7-14.2.
Stock auto is MID 14s. No stock auto will run a 14.0.
What does the Suby Forester run the 1/4 in? I know with the turbo motor it does 0=60 in 5.3 sec.

TC limiting output. Sure, call me on the carpet. I know I've read this but I can't find it anywhere in the service or owner manual. I can't even find redline specs. for the 3rd gen. I know the RX-8 auto. is redlined much lower than the manual. I also know if you look at the torque/HP curves the difference in the rated HP is just due to the RPM limit. In other words, the engines are pretty much the same (as long as you compare 4 port to 4 port - ie 4 port 5 speed to 4 port auto - Japanese cars). With the 3rd gen just look at the engine redline specs for the two transmissions. The engines are the same, so the redline diff. has to be because of the TC, same as with the RX-8 (read that in the RX-8 Technical Highlights CD). In that CD they state the TC is RPM limited so they had to limit the engine RPM and that is why it has less power, not marketing strategy. Hope that gives you somewhere to look.
Also, read on this forum this is the same auto as in the MPV.

Hey, I wasn't really calling you on the carpet. Sorry if it sounded like that. I know quite a bit about the autos and had never heard that before. Actually, I have heard that the TC limits power, but had never had someone give me an explanation before. Hearing it, it sounds plausible. Naturally, I was just curious and hoping to learn more. I changed my rev limit to 8100 with the PFC. It feels like it pulls way past the old 7K redline. I would like to get to a dyno to see if the curves flatten out dramatically above the old redline.

Every major car mag from '92/93 shows the RX-7 5-sp running 13.7 - 14.2 sec 1/4 mile. I'm old enough to remember (and I have some of the mags still) Sorry, don't have any figs on an auto. BTW, someone said a 3.5 Altima runs 15's. That with an auto. A stick can run mid 14's.

Sorry, should have put a smily in there. I was just frustrated at not finding redline specs. in either manual. Thanks GoodfellaFD3S. I wonder how long before the TC explodes when run above 7K ;-). Maybe the engineers were just being conservative?
Yea, it's been that kind of day. Just hibernated my car, and you know you're in trouble when you remove the oil drain plug and hear a "splash" and notice there is no longer a washer stuck to the oil pan drain. Good thing I've got a Mazda dealer four blocks away! The old washer was fiber and was broken. Darn thing only lasted 5 years (that I've owned it). New washer is aluminum.

And to answer your 16 year old kid question.. No.. I do not recommend FD as your first car.. Go buy a car that is much slower.. learn how to drive well, then buy something quicker.. Also, you need to think about insurance and learn how to work on rotary cars..
