• 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

        Ok would you agree most like 90% go ST vs. upgraded twins? Because that is what I was talking about above. The only reason in the supra community to keep the stock frames is for emissions. Now that we have 'affordable' ST kits the same should happen on this platform. It is just the natural evolution as new better options present themselves.

        I have no doubt the VTT solution will be very popular, but not as popular as ST kits that are a few thousand less. If I'm wrong call me out in a years time.

        The word 'all' threw me off I guess. If you are talking about going for pure power potential I would say the vast majority go for as big of a single as they can fit. If you look at the guys who do roadcourse racing many stick with twins and that % (which is just a guess) goes down. It depends on application and what you are doing.

        Can you make a ton of power with twins? Hell yes you can.

        I think there will be merits to each approach. There is no one size fits all.

        i know plenty of people that go a good small ts single for even 500hp. the spool is still good, or better.

        yes i know a lot that just high-flow the stock frames too. depends on many factors i guess.

        Even for a simple log manifold, cheap single scroll.. Would the benefit be there at all? Terrible spool for more top end.. especially when to fuel any reasonable power you're looking at a couple thousand dollars.

        and yeah, on the clutch+fw.. i can understand wanting stock clutch stock flywheel results just for comparison, but delaying the release until 'good' results were had wouldn't be a totally bad idea imo.

        just for more clarification:

        http://www.bimmerboost.com/showthrea...rice-reduction

        i meant how they're 2 separate flanges 3 cylinders a piece, which makes the splilt manifold possible, which is pretty cool for your product too!



        that makes more sense

        and the only thing really raising the price of N54 kits is supply:demand and newness to market.. prices will drop somewhat, eventually.

        the stock frame power curve is kinda fun, but also pretty annoying.. impossible to accelerate smoothly when the slightest throttle tap gives you absolutely insane amounts of torque

        i agree on the potential market too.. it's a pity it's taken so long for people to clue on that these cars are both affordable and can make extremely nice power, easily+affordably for such a modern car. They're common too, and re: neweness.. less wrecked/blown up too - well, supras have custom billet blocks, but that's a whole 'nother tier of baller ridiculousness haha.

        the US market is years ahead of at least the australian market too.
        OHHHH, used kit.. Ok yeah that makes sense.

I would guess something else is causing the misfire, not the flywheel.
        Thank you very much Tony. I really appreciate your kind words from an experienced point of view. I will look into the spark plugs and coils one more time then just to make sure.

        To all that have been wondering about the clutch and flywheel. Neither time or money was the problem with this kit. These are the real world results we wanted. We were not looking to hit a world record, just making sure out kit is consistent with power as all others.

        RPM vs RPM with all other kits, we are on par in that power level. All the dynos Terry has done with his testing on FFTEC kits is the same dyno we used. You can go see it for yourself to justify what I am talking about.

        Clutch and flywheel have been ordered, we will have this resolved shortly. Thank you all for the patience, it hasn't been easy.

        Yup they do that often. Ditch the stock twins and go with a small ST. My buddy was putting down around 475 and switched to a single and is only at 550 or so. Car is a BLAST to drive. And when the cost to do this is 3k or so for a full kit, why not. This is why I think stock frame upgrades will quickly become a thing of the past.

        As far as the linear power band it's a huge plus. The N54 is fun with gobs of low end tq but as you said it's semi hard to predict sometimes. On a track the linear power should be much more welcomed. Even autoX I don't think I would prefer the stock twins.

        I made a post on here before with examples but there is no reason a cast twin scroll manifold would not work great for us.

        Now that STs are coming out and we have the VTT fueling fix all we need now is a way to safely rev the head out to 9k and it's game over.

        try telling that to some guys on 1addicts LOL.. apparently a 700hp N54 is 'ruining the car' or 'going to cause lots of issues'... when the reality is, it's gentler than a 5xxwhp stock frame one in every way possible, and will be easier to drive, and easier to drive faster..

        This is a fact there is nothing gentle about a car making 620WTQ by around 3500, the only word to describe it is violent, I can't even let anyone else drive the car unless I know they can handle it, they will put it into the curb in a hurry, a slightly slower spooling turbo is much easier on parts. I honestly do not think stock frames are going anywhere, a set of stages ones sets you back $1700 bucks and will make a reliable 475WHP on pump and meth, and more on straight E85 with a HPFP upgrade, while keeping stock spool is hard to beat. But the number of bigger turbo cars is going to go up that's for sure.

        exactly!

        stock frame N54's making 600ft-lb by practically 3000? It's been proven the platform can handle it well enough, the chassis doesn't twist around bar mushy bushings, the drivetrain, for the most part, doesn't spontaneously disintegrate with logical upgrades (6MT at least)... you could happily shoot for 500 ft-lb max from a single turbo, faster, more drivable, gentler on every single component of the car... almost 700whp, great spool, no huge torque hump.... heck, you could probably make more, therefore more power, in higher gears if you want just bring it on more progressively than what happens with stock N54 turbos... no?

        i'm sure some people love that level of terrifying though.. that's one solid case for high power stage 2/RB's... 'terrifying'? haha.

        Options and competition are good for the consumer. Looks like a good kit, it seems like a single is the way to go with the N54 now. The look of the top mount is sick.

        We will have the clutch in on Wednesday, and install it. About a week for us to break it in and we'll get another dyno going all the way to 7300rpm.

        Group buy and intro pricing will be delayed until we get that going to satisfy you all. We will have another product out soon as well, just sit tight!

        @VargasTurboTech Swapped coils and plugs from cylinder 5/6 to 1/2. Still got same misfire in cylinder 6 at around 6.2k rpm. Could you verify with Dzenno if misfire detection has been turned off?

        FWIW i was getting misfire codes on stock turbos Map 7, lots of e85 and race backend flash with stock clutch/flywheel.. couldnt get it figured out. It just so happened that same week i was getting my Spec S2+ and Steel SMFW installed. With no other changes all my misfire codes went away. I cant say for sure thats what was causing it but i havent had a bit of trouble since.

        Yea, I wouldn't doubt it either. Terry was with us when we were dynoing. Everything was on check and looked great, misfire looked to be cause of vibrations.
