I’ve got a 1990 GS and was going to do a B16 swap soon but my brother (previous owner) told me I should do a B20B swap instead cus it supposedly is a little torque monster and bolts up to the stock B18A1 tranny…My question is how much power and torque does it have and how easy is it to install?? Also would it be a good idea??? After all it is a hell of alot cheaper 
b20b + turbo going into my teg as we speak, should be done tommorow 
I wanted something other then the standard b18a, I believe the tq will be a nice change.
