As for mine car- the next, and hope, the finalising mod will be the M3 lower wishbones, and that's enough for this engine.
Next step is another car- E92 330i probably, as 335i is an excessive beast for our disastrous roads and the speeding penalties- no sence to keep higher road tax and issues with turbo/fuel pump etc.
More to that, I'm so addicted to the naturally-aspirated engines...
