no man he aint talking about the tvis. your thinking of the mk2 where they take out butterflies or leave them open. the mk1 trives of the tvis open @ 4400 with it open all the time that shit would bog and lean out.
he means the AFM Mod !!
do suspension and handling first !! the car was made for corners not to be fast in a line. do intake exhaust maybe cams then all suspenion. i believe bikeboy of mr2.com message board made a custom rear stut brace for the na mk1.
