    Project E46 330i ZHP

    ** Updated 03/15/2013 **

    After two Speed Touring Car Championships, years of successful racing in Grand Am Cup, and tuning countless E46's for the street, Turner Motorsport decided to build a Championship Motorsport Edition E46 330i ZHP. The goal was to build a great dual purpose car, we enhanced but retained the subtle looks, kept the refined ride and control for everyday driving, and give the car a performance edge for the street. What we ended up with was a comfortable, high performance street car that doubles as a weekend track car, and it puts down lap times faster than most M3's! Here you will find magazine articles, photos, data, info, and listings for all the parts available to make your own 330 perform like ours.




    Magazine Articles:

    TMS Project 330i - EuroTuner, June thru October 2005

    "What's great about the car is that we know every component works. How? Well, it's been tested on track under the most severe conditions and found to do the job. That is the beauty of a company like TMS that's able to do its R&D on the race track. The team literally goes out and tests every part harder than you or I could ever expect to."  full story»

    Weekend Warrior - Roundel, February 2006

    "Turner Motorsport meant to build an "all-around" street-driven 330i as a tribute to their race cars. Boy, did they get this one right."  full story»




    The Numbers:

    We started with the 330i ZHP that has a nice 10hp bump from the stock M54. The first thing we did was install a 3.64 limited slip diff. In all of our excitement we forgot to dyno it as a bone stock car with 3.07 gears. So our 'baseline' is a stock 330 ZHP with shorter gears which works out to an estimated 238 crank hp. From that you can judge that the diff is one of the best mods to make to this car... With our elevated baseline established we re-ran the car after each modification. After all of our bolt-on work and software tuning we gained an impressive 17whp (at the wheels) or an estimated crank horsepower figure of 258hp.
    +23hp over a stock ZHP
    +30hp over a stock 330

    Turner Motorsport Limited Slip Differential 
    BMW stopped putting limited slip differentials in all cars in 1995 (except for “M” cars.) So, if it’s not an M3 or M5 your car does not have power going to BOTH wheels at the same time. In other words, it is “one wheel drive.” This is not good for any type of performance car and if you have taken your car to the track or have auto crossed it you can see why.

    Turner Motorsport E46 Rear Subframe Reinforcement
    The E46 rear driveline and suspension are very similar to that of the E36. An unfortunate side effect of this is that the E46 also shares some of the same problems as the E36. One of these problems is the rear mounting points for the subframe, which can rip out from their spots in the sheet metal.  We have the solution.
