Well it all starts with what your willing to spend. Almost anyone will tell you to get a ITR b18c5 motor if moneys not an issue, but thats a good 5000-5500 dollars. Not including labor unless you are going to do it your self. The next would probely be the H22a, which would be a great choice but a lot more labor to get it to fit. Also you would have to have some real nice suspension in order to get rid of the understeer cause by the weight of the h22a motor. Then theres the infamous b18c1 and b16a. The b18c1 is a great choice but its really all about the money. If you want to spend as little as possible then go with the b16a for 2000 dollars less. And then you can use that 2 grand to build up your b16, and make it a little faster than a gsr motor. If you are trying to make your shop look good then go with the Type R motor
