much needed power

ok, i have a 94 altima gxe and the oil pump is goin out. Ive already found a mechanic that will rebuild it so i jsu need to buy the kit. So i am rebuilding it, but im tryin to add more power by putting in performance parts instead of oem. Ive been lookin for performance packages and found some. I want as much power out of the engine as i can get but it still be reliable enough for everyday driving. Its gonna get a turbo added on soon so im thinkin the parts need to be forged as well. The transmission is also goin out and with the performance additions i dont think it will be abke to handle the power anyway. So i need to find a manual transmission that can hold the power or a transmission rebuild kit to beef it up. Any help would be great.
Thanks!!!!! Sloane
