I have a 85 with a 12A and am waiting shipment of a 13B from a 85'. I am new to this stuff.

Anyone know whats the better for driveing around town and whoooping some ****.. not to mention easyer to install. The 13B come with the wireing harness and the 12A is stock. I haven't seen pics of either so if anyone knows where I can find some let me know.

Would it be easyer to get a T2 set up and hamer it onto either engine?
