One of thr most important things with rotary cars is gear ratios. I heard about this before but it was kinda vegue. kia sportage 4x4. the front chunk or 3rd member. Its a direct bolt in application. It has to be an 84-85 rear. No modifications what so ever, use 84-85 drive shaft. 4.77 gear ratios. like most mods theres some give and take. Its an open diff no lsd. But if your a drag person just weld the spider gears or planetary gears and your ready to destroy hondas,,, ******* hondas! The facory ring and pinion on these cars suck, god knows ive broke my fair shair the kia is way way thicker. I did this to my friends car so I know it works. before the car went 14.4 with a streetport and hes not the gratest driver so im predicting low 13's thats awesome no fuelinjection no turbo and no 13b

Can you fit a 1st gen LSD into a Kia chunk? Or just take the 4.77 outta the kia chunk and put it into the 1st gen chunk?

yeah... suprised you guys didnt know this yet. i think s2000 gearsets work too

not sure but it sounds good

Yeah I bet those are pricy. I tried ths out because it was cheap. $45

well that was the big deal, the mazda geatset was like $600 honda is like $250, but honda used the mazda diff https://www.nopistons.com/forums/pub...1047683664.gif

tested the car this past wensday. she went 13.80 nothing broke. ran with high tire presure, almost no burnout, and crappy launches.

13.50

Now thats what i need ... a 4.77 gearset ... i've been meaning to do it htis for a while, and i think there's a thread about swapping out the LSD unit from your old R&P to the Kia
