i went the opposite way. my car was built on tight budget. got large front mounted intercooler from a SAAB 9000 of all things. had the plastic ends removed and alloy 1's made up to suit. all in, it cost £65. runs roughly same temps as grs, pro alloy etc. its a cheap option. had frontera td intercooler on last s2. just as good and just as cheep. depends if u want a flash name!!
