hey champ im in the prosses of doing my datsun ute with a 13b. first thing is forget engineering the car with that engine cause the out put power is outrages to completly insane power. now you will need modified gearbox tunnel,cut the fire wall hole larger,gear stick moved forward 5 inches or s4 tranmision, 3 core fan with electric fan and oil cooler all custom mounted to fit,you can not use your same diff n need to upgrade to something like hilux or comodore dif and custom it to fit, brake callipers all round n i converted my 4 stud to 5 to fit my 300mm caliperes, custom exhaust system, and gearbox n engine mounts... apart from that it should cover it.. i would go n/a carbi 13b cause ist so much cheaper and easyer to install trust me... and the resale on a 13b 1200 ute is far more better than any other modifacation EG: ca, sr20, everyone loves rotarys and the ones that dont have no idea that these engines are far more better and thats why we can not enginner them cause everyone will be doing it...
