rebeld i whouldnt swap the engines in the cadillac but these cars arent worth much on the market especial the catera ...my catera has 220km and soon its about to die i honestly dont feel like buying a new engine b.c the car is worth around 3-4k,5-6k if its in mint condition ... the parts for the catera are VERY expencive to change the timing belt it is around 800$ + labour so it would be just cheeper to go nutz and try somthin new out i think it will be runing good the catera now is 3800lbs and supra is around there too
