    • Horsepower Freaks single turbo Stage I N54 upgrade kit progress, startup video - Aiming for $5950 intro price

      Many tuners have attempted single turbo setups on the BMW N54 direct injected turbo 6. Up to this point, nobody has been able to come to market with a reliable solution. HPF announced they intended to provide a single turbo kit for the N54 last year. They seem to be progressing further than anyone else and making it into a reality. Expect dyno numbers to come soon but for now the details we have are that this kit will be able to run any Precision T4 Turbo from a 67 to a 76.

      Additionally, HPF is aiming for a starting price of $5950 which will include the turbo manifold, journal bearing Precision turbo, wastegate, oil scavenge pump and hardware, downpipe, intake charge pipe, motor mount, motor mount relocation kit, VBrace, fittings, couplers, etc. This will really shift the N54 turbo upgrade options and be incredibly competitive. After this is released expect a Stage II with fueling upgrade but that is further down the line.

      Good job so far HPF, good job indeed.

        So in a nutshell, this thread should just be deleted. Sounds easy enough. They can make another when ready and it will solve all the bickering in the interim.

        They haven't failed in anything as they haven't sold you anything. Where their development is at is their business. IT'S THEIR BUSINESS. So they are making the best business decisions for themselves. Let Vishnu and others work the kinks out while they sell their kits they already developed.

        Maybe you should read my interview with Chris and see his comments on the N54. It isn't his focus. You and others are acting like the N54 should be.



        Running a successful BMW tuning business is failing just because they don't devote everything to your motor? Right.



        Saying they failed when they aren't even finished yet is essentially saying they screwed up. Yep.
        Sticky its only fair to say that they have so far failed to bring any N54 turbo kit to market. Whether that failure is due to them being busy with other projects (likely true) or they realized the complexity of dealing with the electronics/DI of the N54 isn't worth it to them (possible), they still haven't brought it to market.

        That doesn't make them a failure of a BMW tuning shop (you're putting words in their mouth with that) but it does mean that they have failed so far to bring anything to market. You're inflating what is being said to imply that HPF in total is a failure which obviously isn't true.

        That does not mean they never will.

        People are calling them that or saying they embarrassed themselves when they are flat out kicking ass at the top end of the spectrum making power the N54 can only dream about.

        I guess it depends on what you call easy. Words like easy, hard, hot, cold, etc are all relative to the person who uses them. Adapting a kit with small adjustments is A LOT easier than creating one from scratch. And the point of the person who mentioned the RHD kit being easy compared to the LHD was used as evidence to support the claim that HPF lost the engineers that did the original design; not to contest whether it was designed in the beginning.

        Who cares about E46 M3s when it concerns the N54? This discussion is about the N54 and HPF's relation to it; nothing more, nothing less.

        I completely agree! Seriously, this is what I'm saying. But they still tried, and they failed because they half-assed it and didn't research it. I know you don't read E90post for good reason, but there was a substantial amount of warnings posted over their manifold design that they outright IGNORED.

        No, I'm not. I don't care if HPF never makes an N54 part again. I'm criticizing their behavior regarding THIS mistake or screwup. You're assuming what my position is without enough evidence. Click here to enlarge

        Right. Because that's totally what I said. Click here to enlarge

        Ok, so you want to split hairs then? Then they failed on this iteration of their turbo kit; and they disappeared after promising to make a better iteration. Happy now?

I used that money as a down payment instead and I'm 100% certain I got more "performance" out of the money spend that way.
        I haven't started modding, but I did some calculations and it seems that this is the case. I would be playing more than half the car's price! Not saying that I am not going to go down that road, but it makes me wonder if it would be worth it, since there aren't that many people who have modded the car to the point you have mentioned.

        If I would get an N54 again (I am still hoping for a third car use-case to be viable), I think I would stop at DP's and a good FMIC (I would really consider the BigTom solution) and get a JB4+Flash for E85 and stop there. One need to live with the fact that it is good enough to have a comfortable but fast family car. You could still humiliate most M3's and other more flashy performance-looking cars at a red light. I loved meth but it adds a lot of fiddling and is something one needs to keep an eye at often, E85 solves this IMO much neater.

        $20k will take the car to proper sports car level both power- and suspensionwise. Of course there's no need to stop there Click here to enlarge

        I would add RBs to your bolt-ons list, since that stretches the power curve nicely into the high RPM area.

        Well I kind of disagree, the issues with the stock chassie setup is painfully obvious with the stock snails already. I think it depends on your driving goals and budget, but upgraded hybrids are almost 10x in cost (incl labour) compared to a JB4 and give you an additional 50-75hp (less than your jb4+dci stage 1 setup).

        If I had a 1M coupe it would be a different story since you prob could argue that handling is fully sorted by BMW M already, but I "only" had a 335i
