those welds on that exhaust and box are awesome ,would the input shaft have to be machined down to fit into the crank or would a different spigot be used instead? any info on the clutch ,was an sr or rb clutch used with a redrilled flywheel?

i always wondered if it was doable to use an rb box seeing as the rb20 boxes arnt sort after and theyre pretty cheap ,there pretty weak behind an rb but would be awesome behind an angry A series

whats 5th gears ratio compared to a 60a 5 speed 5th ratio ?

also would an mx5 6 speed be a viable option to put behind an A series ,seeing as they come out of a small car youd think it would be compact enough for a datto
