Fd3s transmission and other questions
Before y'all start bashing me or telling me i m dreaming, i have a fully built bottom end and stiffer springs in the head. I got an 8.8 irs with a v8roadster kit. My transmission choice was an fd3s because i could not find a tII. Tranny is at the machinist getting a bellhousing conversion from another 5 speed i had. My question is who ese is running same drivetrain as me ? Second question who else is running and fd3s tranny? Third question, if u answer yes to any of the first 2 questions, how much power u got on it, and did u ever brake one ?

Most people who are going to the work to swap transmissions these days are going with the BMW option. The FD transmission is a lot more work than the BMW one because of the weirdo pull-type clutch, and the ratios are spaced wider than ideal.
I have an FD transmission, but it's in my FD.

Red through most of it until i got bored reading. Seams like everyone had their own opinion on gearing but no actual proof of how much it can hold... i dont care about gearing as much as i care about how much it can hold. In fact i like the gears on the fd the fact that 5th is longer which is what i m looking for and besides Ever could be adjusted with the correct ratio in the diff and tire size

No problem. I have no doubt that the ratio will suck on the track or at an autox event, however I have no complaints on the street.
Beware though that these boxes do suffer from bad synchros, and if I recall correctly they are double on 2nd and 3rd, so somewhat expensive to replace.
The box itself will let go above 400wtq; the weak point is the shaft, which twists under torque and eventually snaps.
