Finding a manual FWD Bluebird tranny is kind of rare, but their strength is just like the US FWD Se-rs they are weak when putting down lots of power (what Greaser said). Most Sr20de-Ts (that can be used in a FWD configuration) overseas are either automatics or AWD.
With a FWD sr20- you have 2 options for your tranny.
1. Cryo-treat your gear stacks (if putting down alot of power, your gears will still eventually break- mostly due to the design of the tranny)
2. Replace the internals with a PAR gear set. This is a drop in fit with a streetable (syncros, etc..) or full race (dog-cut) set up.
