• Updated photos showing CP-E (Custom Performance Engineering) N54 Twin Turbo upgrade kit progress - Yes, it's still coming

      Updates on this twin turbo upgrade for the N54 have not been posted in some time leading to some speculation that CP-E was no longer working on it. As a matter of fact, the last time anything was posted on it was in November of last year. That updated showed a mock-up of the manifolds and the turbos. Since then things have progressed to actually having the turbos and manifolds mounted on the motor with a mock up of the piping.


      So yes, this upgrade is still coming. The N54 turbo upgrade market continues to heat up and really the main thing it is missing with a single turbo option out (kind of, still being tweaked and no real info from the handful of customers who have it) is an option for upgraded larger twins. For now, the only twin upgrades have been to the stock turbos.

      There is no timeline of completion but it looks as if CP-E and Vargas Turbocharger Technology will have the main turbo upgrade options for larger twins on the N54. Expect debate on the forums to soon shift from which tune to get to which turbo upgrade to get. Let the single versus twin debate begin!

        Soooo 3 more years before this thing comes to fruition? Seems like anything N54 related is moving at an old drunk snail's pace.

        I think you may have been comparing this to the Single Turbo's. They use pre-turbo O2 sensors to split the banks. I.E. HPF and FFTEC Manifolds. With the twin turbo's you can maintain the same O2 placement as is the stock setup. The reason of the difference comes down to being able to tune the car properly and not have interfering signals(AFR).

        Since, I'm only at the race course, TWINS all the way! This should pave the way for the first 1,000HP N54! Are we the new supra?

        good post Rob.. I hope we can make xxxx-whp on this platform. That would be awesome and I would be very happy to have chosen this over other when purchased in 2008.

        Yeah. That's exactly what happened. Wasn't thinking.

        Love CP-E stuff! Looks like they changed the manifold design SIGNIFICANTLY since their last pics were shown. As I have always said, it is going to be VERY "busy and congested with parts, require much creativity, and still have some disappointments here and there" trying to make this work. Some OEM supporting parts (non turbo related ie motor mounts, coolant plumbing, obviously oil and coolant lines, heat shields) are going to have be discarded, revised, etc. Looks like they now just need to get some compressor outlets in place, along with all of the oiling an cooling lines. It is going to be a VERY hard and costly install, and hopefully it clears the actual engine bay when said and done. The tuning side adopters will be interesting to see considering they are using the external gates.

        The rear turbo inlet I am a little confused on where else it will be plumbed, or if the filter is right there? If so, not real impressed there, but again with a true twin turbo setup on the N54 there are going to be some things you have to just "accept" as it is a disaster to say the least to do this right. If anyone can though, it is CP-E.

        The cost of this kit (although likely is very fair as CP-E is known for awesome parts produced correctly and at a great cost) it will be VERY expensive. Definitely $9k+ for the kit alone, at best. Price you pay to go fast though. Looking forward to how this comes together- they do not have far to go now with the hardware.

        Glad to hear there is more Competition in this arena, and also see some pics/results as well. Also glad to hear Vargas is going the OEM approach of Turbo orientation, although I am not sure how the inlet plumbing is going to have ideal size yet have proper fitment. Retaining the OEM Wastegate Internal Actuators will also keep Vargas open for all tuners to tackle, which is great, but still maybe some growing pains as rattles and adjustments are necessary over time using the Garrett gates that likely will not weather the open flapper storm they were not designed to endure. Whatever the case, whoever can defy all the pitfalls and make a great kit that fits cleanly and at a fair price will ultimately win this market, it is just going to be very VERY tough to make a kit to fit this bill.

        +1 Im dodging boulders and jumping snake pits as we speak trying to avoid all these pitfalls.

        I love this counting chickens before they hatch and proclaiming 4 digit hp figures on paper. Wonderful.

        Good thing I didn't give them my car 2 years ago lol!! They look like Borgwarner turbos... And I can see one of the intake pipes going into the inner fender well

        Ya, it is rapid prototyped plastic, you can tell by the abrupt flats on the pipes. The machine lays down a series of melted plastic layers. Some 3d printers use a powder and epoxy.

        I'm very mellow and easy to get along with. Or something. Or I just see no point in pulling my hair out and banging my head against a wall.

        This will be worth the wait though.

        in all honesty, price is subjective. The appeal of twins over a single in tuning aspect alone is worth arguing over, but not really, hands down i think we all would choose twins. but when a company like cpe gets involved, at least you know it will a solid choice. the price difference over proven hybrids doesn't really come into play since the hp goals your shooting for are well beyond what "normal" people strive for.. especially when considering your doing this to a bmw, which as much as we hate it, does carry more cost per hp. what cars built from 2007 on can you theoretically achieve 650+hp from and at what price... to me, the single isnt even an option yet since nothing has come from it even though its released. A true TT 335 would be a VERY appealing car to have..

        The actual price difference between a single and a quality twin setup isn't really going to be all that large. The FFtec/vishnu setup still requires install, tuning, etc. For me, if I'm doing the upgrade, I'm going to get the best quality upgrade. If going that far no reason to skimp.

        I like what I'm seeing from CP-E. If it's more expensive, likely will be, it sure looks like the price difference is warranted.

        By the time this comes out, maybe someone will have come out with software for a beefed up DCT, then maybe the DCT N54 can actually be pushed further!

        It can be pushed further...

        You are right, and I know that we have members like Buraq that have managed to push the DCT without any problems, but at the same we should not neglect the stock dual clutch's torque capacity (6MT has a much greater tolerance), unless I am severely misinformed. To push it beyond FBO and get upgraded turbos, I'm sure it would still be amazing; however, it just makes so much more sense to upgrade the clutch too! No need to worry about clutch slipping or anything. Click here to enlarge
