So i have been doing some research and still cant figure out what the best transmission would be. I am going to be driving as a street car, but also dragging and drifting with it. any ideas on what transmission i could use for an everyday driver but also hold up to a reallly fast car? Im new to this forum but have been around cars for a while.

I had considered but im rebuilding the engine and its going to have quite a bit more hp. the only thing that concerned me about the rb25 transmission is it might not hold up while racing it. I considered an OS Giken but really not sure how that would hold up on the streets since its built for racing. I have heard a lot of good things about the rb25, im just kinda skeptical. Thanks for the response

the z32, rb25det and rb26 transmission gear sets are the same youll have no problem giving the 25 trans hell, im laying down over 600whp daily on a stock 25 transmission nw no problems, it makes bi weekley 1/4 events on m/ts, stop worrying about the transmission and worry about the rbs pos oil pump drive collar and oil pump problems!
