i can get both engines complete for about the same price in my 94 RS. the car is my daily driver, Im not going to crvtec, or turbo. I was wondering if it would make sence to put in a b20 instead. I would most likely be swapping my Fidanza 8.5 lbs flywheel, and exedy sport clutch. is the bigger block gonna be a simple plug and play setup?. The rev limiters are going to change i assume. If anyone can help shed some light.

my current b18b is okay. my head is making alot of noise (due to wear and tear), just trying to rationalize a rebuild, or just simple engine swap. As i understand, the b20b has like 126 hp (flywheel) or somthing and my b18b has 140 hp. I think the b20z is like 140 also. if i put in a b20b will i have less power?.
