if the length of the box is the same then the biggest area of concern will be the width of the belly and whether or not the uj required for the prop is larger than on the t9, i would struggle to get a larger uj between the chassis rails, it clips now and then as it is. sbd say they don't make the bellhousing to go from the c20 engines to the t5 box because they are not suited, c20 revs hard and the t5 is built for torque .thanks.
