Hi guys looking at installing BMW M3 throttle's on a k20z4 motor, just wanted to find out if anyone has atempted something like it. Installed electric water pump (tyred of replacing head gaskets every time the altinator belt comes off and the car overheats) on k20 some tunning and 138wkw 276nm torque, all stock internals. The throttle in theory should work, not doing much for the kw but should increase the torque. Have seen throttle's on a k20 witch is pushing 151wkw normal aspirated then again the guy spent a 3400 dollars on a set of throttle's. Fully forged motor though. Saving money were I can for more mods that make sence.More bang for my buck I guess.
