why the hell does it cost soo much to swap a 20b is the motor that expencive or is it the modification? also what they max hp u can get outa this motor im guessing alot mroe then the 13b.

 

It costs a lot because it is not an OEM offering. A number of components are custom.

What is the max amount of hp that can be squeezed out of a B18? The answer, don't know. People find ways to create more and more power every day...

 

There is a lot of custom fabrication and tuning.

Peter Farrell offered the opinion, based on testing with my motor, that a 20B built like his 13B-rew drag car (28 psi boost, nitrous, 650 hp) could produce 1000 hp.
