Welcome back
20B is a turd really, too heavy, too stupid, wrong sound!
It ruins the weight balance of the car, it ruins your wallet, if you want a car that sounds like a Supra, buy a Supra
13B is the way to go......... true rotary noise, and as much power as you could ever dream about.
13B street port, BW400SX3 turbo or GTX45, cosmo intake manifold set up, water injected 36psi boost 850bhp or just put around on 15psi and have 485bhp, put on a good electronics package, nice gearbox, and enjoy it!
