I have a roadster rear end and a 200sx rear end. i would have to modify the 200sx because it uses a spring and lader setup i believe but i know it would be worth it .. see the older 200sx axel is not as wide as the new ones i think .. i will figure it out i wana stay away from a huge drag project.. with biggger slicks and stronger rear end i wont need to tub or even mini tub yet. this ka24de is maybee pushing 190 to the fly. my build one is pushing 300 to the flywheel. Built similar to the nissan offroad truck ka24de project with weber induction. I also forgot to mention i do have traction bars under this 1200 .. when i jack up car from pumpkin , right when rear end is lifted the body lifts as well .. really stiff in back. i think i need to make it sink a bit on the launch .. i dont know .. thank for all your guys input. i will keep u posted on the project and i will submit some photos.. and btw the axles were out of the vehicle when i welded the spider gears.. and i have broke 7 axels in 2 years.
