The V160 ratios are not that different than the R154 they have differences. I am not dsayign they don't.
But it takes some banging and a custom drive shaft to fit one in. not to mention there is no tach cable coming from the v160 .So you would need to find a way to deal with that also.
if i find the other thread where the gear ratios have been gone over and over, I will post a link.
In all Honesty the R154 is enough for the 1J the Final drive might not be the same as the V160 but Are you really going to be doing 180MPH+ everyday. If not then it really won't matter to much
