    • 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

        Thank you all for the support and the kind words. We will be releasing a group buy shortly with special pricing as well. More testing will follow very soon on other vehicles for fitment, as well as more power.

        It is on par with all other kits in terms of power with similar sized turbo and fueling. Spool will always be an issue when going to bigger sized turbos like this. We are using a bigger exhaust housing AR than most would consider but it is not too large.

        Low end torque is great and starts off about 1k rpm sooner than other kits with similar sized turbo. Spool can be maximized with better exhaust as well. Here is the log from the dyno run, 5th gear.

        Yes, the head flange is two pieces. The separated manifold makes for a very easy install. We installed the turbo kit on the car with all suspension and subframe bolted up. The manifold was easy install from the top of the car, took us 2 hours to install the full kit with only a jack.

        We made this easier for people that like to DIY, and do not have a lift. This kit can be installed at home in a garage, with an experienced mechanic of course.

        Boost control has not been an issue at all, wastegate priority is very high as it is in the line of flow after all the merges. It looks a little off due to the tight spacing and o2 sensor placement. We have not had any issues with o2 sensor burning, nor tuning and boosting.

        First day off the lot with e40 mix testing:

        This is great and I love more and more ST options are out there and coming out and I can't wait to see used kits in the 3-4k price range. 4k used kit and I can hit 600whp or more? Awesome.

        But come on spend a little more time and money and make some real awesome numbers and do a proper release. The fact they rushed this and refused to install the necessary components that they even list on their website makes me not want to be a 1st adopter.
        We understand your point of view fully. We wanted to show you what this kit can make with the least amount of modifications possible on a stock-like car. Making more power is not the hard part. Ensuring the product works flawlessly is more important to us than power.

        We offer lifetime warranty on all fabricated parts, (Manifold, Downpipe etc.) and use the highest quality parts and material on the market. Nothing on this kit is shortcut or rushed and includes all parts needed to make your n54 into a monster.

        Clutch and meth kit will be here soon for more testing. We have a beta tester coming in a couple weeks ready for 700whp+ setup. More info on that will be released when the time is appropriate.

        hmm.... OK. WG seemed to be in a runner as opposed to the collector on the other bank.

        You are correct, it is on the runner. It's on the runner after all the merge, we cut it and made sure it was getting all collectors to merge before we chose that specific location for the teardrop WG.

        Yes, Vargas fuel pump is on the list as well. I like to test things one at a time to get every bit of information I can for the customers.

        Special as can be. Just wait one more day, I hope we can please you guys.

        Thanks for the reply, I didn't mean to come off as a dick, but it is known it has to be replaced. This kit looks great. I can't wait to see it rev out to 7200 on a high boost map.

        Any reason you chose JB4 over Cobb? Will we see pump numbers, pump + meth, E85, etc. in the future?

        No problem at all man, it's all in the business. You can't please everyone! LOL.

        We chose JB4 for its consistency and user friendly availability. Pump numbers will not be tested, I don't run more than 12 psi on 91 octane. It feels like a 350whp car at that power level to be honest. I will have more e85 testing as well as pump and meth numbers in the near future.

        Kit looks pretty solid, not really understanding the Flywheel issue though, our stage 3 car had the stock Dual Mass flywheel and had no problem revving to redline and making 700+WHP for a few thousand miles with no issues, we actually just pulled the tranny our of that car yesterday to change the clutch, the flywheel looked fine, but we are putting a Spec Steel SM back in it though. I would guess something else is causing the misfire, not the flywheel. For the guy up there who said he cant wait to see 3-4K kits for the N54. So let me get this straight you must want the cheapest of the cheap Chinese junk, because you really cant even get quality parts and a turbo for a kit like this for 3K, let alone the labor time to build it etc. The price point on this kit is in a good range for what you get.

        i'm pretty sure the vargas flange was a 2-piece.. seems like a great idea to me to keep it all separate for ease of install, just gotta make sure all the vbands are high quality and tight!

        not the manifold, just the flange that bolts to the head.

        i'm assuming dzenno turned off the knock detection.. the flywheel misfire issue has been well known for a very long time

        a DIY kit could be done for probably 3-4k pretty easily... but no way for an off-the-shelf twinscroll one.

        As I said, if you spend 3K on a kit you are asking for very poor quality parts and an Ebay turbo, also he did not say DIY, he said when people start offering kits at those price points. That's not reality. I do have to agree with his point that if you are going to spend all the time and money to build and offer a kit, put in a SM flywheel or run it how we did and get the proper results, we all know people like big numbers. Doing a clutch / flywheel install takes 4-6 hours, and would have made a world of difference.

        I said USED kits bro. There already is a cheap BNIB N54 twin scroll ST kit for $5,600 new. I'm not about to buy an FFTEC kit for lets say 9k all said and done out the door for a car I paid 15k for a year ago.

        The more ST kits out there the better for all of us and the community. There is no reason an N54 ST kit needs to cost considerably more than the equivalent supra kit(as an example). If anything they should be less expensive as there are a TON more N54 ST potential customers. For anyone interested look up Supra kits to get an idea about of what I am talking about.

        I said it a year ago and I'll say it again, once affordable and well tested/vetted ST kits hit the market the interest in stock frame upgrades will decrease significantly if not go away altogether. You have to run the $#@! out of the stock frame twins to hit 500whp. On just pump alone you can't hit north of around 460-470whp on upgraded twins. The Supra guys only upgrade stock frames for emission reasons. They all go ST and the N54 should go the same way, I see no reason why it would not. Having a linear power band should be very appealing to many people.

        They don't all go single turbo and it isn't the same thing. Secondly, twin or single it completely depends on the turbo choices and manifold design. Twins can outperform a single and vice versa. There is no 'single turbo only for performance' rule in existence.

        But I mean hey your tone sounds pretty positive and all...

        yes, i agree.

        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.
