Picked up a 93 xr2 couple of years ago did mods to it, chip, bubble top, manual boost control set 15 psi, lowering springs, double rear sway bar, struts and brake slotted, 2" exhaust, wheels and tires. just picked up a 91 n/a body in real good shape. 93 not so good. over summer will be smushing them together and come up with a 91 xr2. I have found a lot of good info on site. I will rebuild the xr2 motor and hopefully tranny with 5th gear and lim slip. I will be doing track nite in Rockford il. a lot of miatas need their attitude adjusted. ha ha. I will update as build goes on. If I have questions or get stuck I will reach out to ya'll. thanks for all the info.
