@c_guldner: EP. 2 Turbo LS Wrangler Adapting the Np231 to the AX15 transmission. Since my Jeep came w the 4 cylinder and the weak ax5 transmission, the input gear on my transfer case has to be changed out to work with the new transmission! 21 spline to 23 spline. Next time we’re hopefully buttoning up the motor, attaching the transmission and transfer case, and it’ll be ready to drop in the Joop 🔥🔥 exciting stuff happening SOON #jeepyj #turbols #turbolsx #lsswaptheworld #lsswap #jeeplife @novakconversions @lsx @holleylsfest
