This is a project we’re very proud of. After being mistreated/abandoned by another shop and tuner, this heavily-modded 2008 BMW 135i was left in an shameful state. Once it was brought to ISW, we began by inspecting/fixing all of the previous modifications, such as the Vargas Stage 2+ Turbo’s, BMS Trunk Meth Kit, Stage 3 Fuel It! LPFP, Vargas HPFP, and Nitrous Express Kit (just to name a few.) After that, we addressed the rough-running issue by replacing the spark plugs, ignition coils, fuel injectors, and addressed a fuel leak. We then revamped the cooling system, fixed some leaks and performed a coolant flush. For good measure, we performed an oil service and replaced the battery that had died from sitting for so long.
Finally, we removed the hacked-up engine harness and JB4 (hacking compliments of the previous shop) and replaced it with a good-working engine harness and new JB4, as well as updated the JB4 board with an N54 antilag and port injection driver.
Now this N54 135i is good for up to 700HP (with Nitrous 😬) 🏁
