rotahavik.co.nz is a good place. you will need all new mounts, engine and box. new driveshaft, rad to keep up, oil cooler, the whole deal. go a heap harder that a 4k, esp good exhaust, carb, ported. frount mounting it maybe eisier, just a box tube with 2 45deg plates on it. or side mount, if the center plate is over the starlet xmember. nedskool 13bs are side i think. 12a cosmo plates are side mount i think but you could alsways just put a front mount front cover on.
