clutch conversion from reverse to normal

i have an 89 supra and have had my eye on that tilton clutch for 5300, i could get a 2jz tranny cause i have a 1jz but i was wandering if there was a conversion kit to make my tranny use normal clutches instead of reverse clutches, without having to spend the money on the whole tranny, any help would be appreciated :)

What is wrong with your current transmission? The R-154 is a good unit, and more importantly why exactly do you need a $5300 carbon carbon clutch for a MK III Supra?

It seems to me that if you were seriously playing in a league that requires that kind of hardware you would have the means to fabricate what ever you need.
