could a 20b from a cosmos be put in a 1st gen? all work done by me and friends for 10k and what all would i need to do the swap

 

You need to search.

 

Hitman has a 3 rotor but its not a 20b its made from 13b housings

 

Check the engine swaps forum here. Theres a whole section here on just that.
It can be done, and it works quite well. I suggest getting a racing seat though, those engines are scary.

 

yeah i know its gonna b a while before i start this b/c i messed up my hand 4 days before i was supposed to start working so they are waiting for me to get a medical release here in about 4-5months im just trying to get it all planned out so i know what i need to have done or do my self so on and so forth
