hi
no i did not have to modify the steering, i just had to make the exhaust headers go around the steering arm, its easy , the sump is the problem, if do the conversion make sure you get a 1uzfe with the sump mounted in the front, mine was in the middle and this caused problems,i fixed it and then i found out that there was a front sump model, it was too late to swap, job was done, if you want the motor lower, i did i had to cut and modify and weld the alluminum part of the sump, this causes the sump to bend like a banna after welding, this was the hardest part of the conversion!
car has just been base tuned today and we tuned the blower on and had 7.8 psi going into the motor, it was very fast, but the standard injectors said no way, they were at maximim duty cycle at 5000 rpm, so i have just done a mission and got some 7mgte injectors so they will go in tommorrow, we will re tune car and then she goes on the dyno day after and final tune done, so hopfully i have a power figure from her! can't wait
