Aluminium a little different than brass radiator...... Price seems to be rm800 for the aluminium on Mudah and a new 'normal' radiator costs RM500-600 depending on how many fins you wish to have...... 3 fins/columns pun boleh.... done in 'THE radiator shop' in Klang.

Some one asked for clarification : Aluminium is used due to its lightweight construction and a little to do with conductivity.....
2 row aluminium with 1" tubes = 5 row copper brass with 1/2" tubes
If copper do 1" tube it would have to be a thick wall too, the same with aluminium, but it would be too heavy laaaa..... something like that..... performance wise, you'll have a lightweight radiator if you take the same amount of fins/rows.......
MR2 standard is 2 row/fin only...... I doubt 3 fins can fit into the cramped area unless you move the aircond condensor away....
