Woops didnt see this section, so heres my repost in the correct section: How far can the 8L A3 1.8T engine be pushed stock? I'm seeing bolt on ECUs and turbos ranging up to 350bhp... surely the engines not this strong? Im thinking of to begin with, an induction kit, uprated oil pump, sports exhaust to start Then either a turbo or ECU upgrade Now, theres a 200bhp ecu, and a 225bhp upgrade, and a 350bhp turbo. I presume an intercooler would also need to be ordered about the same time. How good is the clutch/gearbox? What do you think the engine can take without any engineering? I want to reach the best performance i can achieve without replacing the whole car, naturally. I also dont want it to blow up in a week of tuning.
