the 13bt-rew is much better and with minor mods you can rinthe twins non sequentially and eliminated the whole vacum system almost. making the simple install but then you need a pfc or haltech or your choice. the price diffrence in the motors is pretty much the turbo diffrences and the 4 years technology diffrence. the 13brew had the lightest rotors to date till the renesis engine. i think.

o dont for get they did stop makingthe rew oinly in 2002 so many more will be on the street in the nex 3 years and the prices will probably be coming down.
