Ok since this is the second time I have typed this short version looking to make 500-600 hp around 15-18psi on this in my 73 rx3 I want stock shifter location because besides wheels ride height and paint I want it to look stock this is a running c series #488 still going to pull it apart for a rebuild I don't want any firewall mods and need tips on shortening this up without loosing a rotor I already have my street ported cosmo re that is now going under the bench for later it only weighs 1950lbs stock so I thought about keeping my tll tranny any thoughts would be welcomed

 

I haven't dropped on in an rx3 before but chances are your engine will be quite far forward, keep your fc box and shorten your shifter by what ever you need (max is about 165mm) or grab a s6 box and change the tail housings over. rear mount the engine too (factory mounting points)

 

good idea on the mounting i had thought about it i just need to check clearance to my steering box. and i have a line on a s6 box now just didnt know if it would help so i guess i will be picking it up just incase thanks
