nice conversion. it appears that the e30 has a little more space in the engine bay from the pics.
a few questions...
1 - have you replaced the cam belt on the motor? the round rail isnt a non interference motor and will bend valves if the cam belt fails
2 - how are you going to change your forum name now....
i do these conversions for R45k into almost any rwd body but i prefer using the 21r cressida box, my reason for this is that if the modded e36 box fails its a huge mission to replace it if required. where the 21r box is a straight fit onto the bellhousing. my build also includes a new cam belt and full service on the motor which is hand picked by myself.
i did a quote for a mate a while back and it came in at around R90k all in for a completely rebuilt from the ground up e30 fitted with the v8, big brake kit, coil overs, respray, etc etc etc.
i have sold my last v8 e30 to a fellow club member and am in the progress of building a new 1, but this time with a fully modded n/a lexus v8 motor.
i do happen to have a complete e34 rolling chassis available should the need be too great for a few of you... just saying you know...
