What's the latest obsession with welding T2 wastegates?
It's kinda pointless, it's just something that everyone went on about for months and then it became a fad... If you intend to have your car as a daily car, I highly recommend against it, you just need to actually shorten the actuator arm or increase the spring pressure...
All it does is strangle the engine at high RPMs - yes, it'll give you a massive peak midrange, but you're just likely to overheat turbos, precups, heads... These engines aren't exactly the best for high heat levels, they really don't like it, and welding closed the wastegate just accentuates this and gets things red hot... You can get away with it on larger turbos, they've got such big turbine wheels, there's little to no restriction anyway...
Everyone assumes these engines are just invincible, but they just aren't... They do NOT like high temperatures...
