    • A new contender enters - Introducing the Ventura Motorsports E9X N54 top mount single turbo kit - Comp 6465 turbo shows 593 wheel horsepower

      The N54 turbo upgrade game continues to get more contenders vying for the throne and the newest challenger is from Ventura Motorsports. This is a top mount single turbo kit and the pictured and dyno'd kit below is using a Comp 6465 turbocharger. The manifold is a T4 Twin Scroll with a three inch Vband two piece downpipe that bolts onto the stock location. The price? $6,899.99 which certainly places it among its direct competitors.


      What you get for that $6,899.99 is the following:

      - T4 Twin Scroll Manifold
      - 3" Vband Two Piece Downpipe Split to bolt onto stock location.
      - Coolant/Power Steering Reservoir relocate bracket, wires, hoses.
      - Turbo to intercooler chargepipe, all silicone hoses and clamps.
      - 4" K&N Filter
      - Turbo Blanket
      - MAC Solenoid with AN fittings/lines to guarantee no boost leaks.
      - Billet CNC Coolant outlet, with new hose for water pump.
      - All oil feed/drains and plugs with shielded hoses.
      - Twin Tial MVS wastegates with all springs and external dump Tubing.
      - Comp CT4X Turbo of your choice, Billet wheel, triple ball bearing. (Call for specifications or other turbo inquiries)











      The turbo kit includes everything necessary and tuning is recommended with a BMS JB4 and the BimmerBoost.com Flash Software. So let's take a look at an example using a Comp Turbo 6465 turbocharger.

      Specs:

      VM Top mount twin scroll kit
      Comp 6465 .84AR 3" Catless downpipe Tial Blow off valve
      VRSF 7" intercooler and charge pipe
      JB4 G5 With Bimmerboost Flash
      255 Inline pump23-4 psi on Ms109

      Could not rev to redline because we are using a stock car for testing and causes misfire due to dual mass flywheel. Stock clutch and Stock exhaust with secondary cats, resonator, and mufflers all in place.


      Result? 593 wheel horsepower and 540 lb-ft of torque at the wheels on a Dynojet in STD correction. Not to mention 90 degree weather. The N54 turbo upgrade market continues to get more competitive. Who benefits? You do: http://www.vmotorsports.com/turbo-ki...turbo-kit.html

        There are arguments either way but I think for a single setup a top mount makes the most sense. I think if someone wants more of a sleeper look and is more interested in a setup that isn't shifting the powerband all the way to the right twins make sense.

        There are arguments for cooling, ease of reaching the turbos, etc. There will be advantages and disadvantages to either but the most important thing IMO is the quality of the manifold design and the tuning that accompanies the upgrade.

        A junk manifold with a top mount single will be crushed by an excellent twin design and vice versa.

        Ok got ya. Looks great I just wanted your opinion. Only thing I've heard before was about heat and cooling, as in it was better to mount it low. Looking forward to some videos!

        Thank you Tony, I am looking forward to your double barrel kit as well. So no more problems with e85, run it 100%. I will be happy to break 700's if everything goes well. I don't think we should have a problem though, the only thing is that the turbo only flows 800 Crank hp. A nice 29 psi pull should suffice. How many meth nozzles and size have you ran before?

        We have gone through both routes and chose the top mount. There was very little difference in manifold sizing from a top vs bottom mount. The ease of installation and maintenance check on the turbo is much easier. As Sticky said above, it's all in the quality of parts and design that truly matters.
