Hi everybody,
My car is FZJ71 with turboed 1fz-fe motor producing 1000 wheel horse power driven by h151 & hf1a. I'm facing issue with the low range ratio which is 2.488:1 and it isn't suitable for 1000whp so I couldn't find any higher ratio for hf1a TC. I'm thinking about 19 spline spilt case TC...
