A complete kit would cost you $5000 from Vortech. I added an oil-cooler coz I do a lot of circuit racing. I highly recommend it for anyone planning on keeping the internals stock:wink:
, I accept the offer on the condition of declaring the mods
Thanks for that mate. Do you have any idea of what 0-60mile / 0-100km times you get? Also what does it run over the quarter mile?
Do you think it would be quicker than a stock 135i?
