Even better is to use the A610 intercooler and convert it into a chargecooler. The GTA intercooler is a terrible design with no flow direction at all, wheres the A610 unit flows from one side to the other, rather than both inlets at the top...
The Alpine isnt the problem....its the new kitchen, central heating and christmas (bah humbug!) that have done....havent got any money left to modify the Alpine much for next year...D'oh!!!!
