For those that have had their 'addiction' for several years and have done a reasonable amount of modifications, I thought it might be timely and informative to 'rate' your mods and maybe list what you'd do different time over. With my car, I think my best modifications are the Brembo + PBR upgrade, PWR ZF cooler (given the constant milkshake worry) valve springs and GTX3576R. What would I do different? Tough one, but I'd go a bigger intercooler straight up, full exhaust instead of the double hit with the hi-flow cat then upgrade, debatable whether I'd go turbo side again and go the bigger injectors straight up instead of doing the F6 ones then ID1000's Look, plenty do stuff twice and I'll admit you get sucked in thinking you need the biggest and best of everything to extract reliable power out of these things. The reality is, you don't.
