I am thinking of a RB26DETT Nissan skyline motor or a 2JZ-GTE toyota supra motor. while looking most of the RB's come with a 5speed MA transmission AWD. & the 2JZ has some varietty with the tranny. Another thing i want to know is if i should even change the trans. or can the stock 6speed silvia tranny handle as much hp. do u think a silvia would be better with an AWD or RWD. also if u know of any sites that sale the motors that would be helpful & i will do upgrade to the motor choosen

naw screw that
swap in a KA24E with 14:1 pistons and dual 44mm mikuni carbs.
