Hello all,
i recently purchased the new facelift Audi A5 quattro with the 7speed double clutch S-tronic gearbox, putting out std 211hp and 350nm of torque.
I have already done an ecu reflash by IC chip tuning from Switzerland, performance is defentially a huge boost compared to std but not near what i want.
(Mind you i have a 2-ton truck pushing out 500hp and 1000nm of torque from a stupidly small 3.2L 4cyl turbo diesel)
so my question here, how much different is the K04 from the K03, has anyone tried to just modify the internals (shaft, bearings, turbine wheel and compressor wheel) of the K03 to be a K04? (as from my information, the housings and dimensions are the same but the internals are different. worst case you might need to mill the compressor housing and turbine housing to make it a little bigger to suit).
being a modification enthuasit i also want to ask, is the K04 really the best turbo upgrade out there? power levels of 350hp is good enough, i believe the s-tronic can handle 550nm of torque which puts the K04 in the safe area.
i am also a big fan of the IHI RHF55 turbocharger, borgwarner S200 series, mitsubishi TD05h-16g small, (same as the evo).
any insight would help alot thanks!
