its a good idea to strengthen the front cross member since it no longer gets used

its fairly straight forward, mount the engine from the front in-between the chassis rails like you would n rx3, mount the gearbox the with a similar bracket to ca18 one. you'll have to make the tunnel higher through the middle and make space for the clutch fork, also look into doing the shifter extension mod otherwise your shifter will be a little bit to far back for comfort. when i made my exhaust i ran then headers to the rear firewall across to the passenger side and the rest was pretty well muffler.
