Interesting. I read somewhere that one can bend rods with stock turbos with too aggressive a tune?I have MMP3's and Eugene says that unless you have a built engine the 1ks are overkill as the 3's have enough spool and power to bend rods.
I searched MMP and didn't find too many people with the kit. I'd like to hear your experiences with this kit. Does anyone have 10k or 20k miles on the kit? Any feedback on this kit is greatly appreciated.

I've had the MMP 1Ks on my car for around 10k miles now give or take 1k, with absolutely 0 issues. I've been running them at ~26-27.9PSI depending on IATs and whatever else the DME takes into account, with only LPFP modifications and they still pull to redline perfectly, and FWIW I've been able to beat everything from a modded STI (easy mode) to a Hellcat (by about 3 car lengths) to a slightly modded m4 comp (very close, he was at my bumper both times) on some "Mexico digs". I've also posted logs on here where my spool time even bested what Mauricio advertises them to spool at on a 6MT and I'm in a 6AT, so I'm a huge fan.
In the MMP group on FB you can find much more info on longevity than in most forum postings. Lots of people running them passed 20k miles already with no issues, and I believe Eugene was able to run his 1Ks at 30PSI for 30-something thousand before he blew something in his engine - and that seems to be the most common reason people stop counting miles, not due to turbo failure. I've seen way more posts about people blowing their engine with stage 3s or 1ks than I've seen of any failures, probably a 10:1 ratio and the only failures I can think of were on the stage 3 1.0s. With the upgraded exhaust manifold and larger turbine housing of the 1Ks and the gen 2 stage 3s, I dont think you have any reason to worry about blowing the turbos unless your tune is off and you dont have the proper supporting parts.
I finally (literally an hour ago received the package) got something that will help me push my fueling more, and I plan on turning up the boost some more and aiming for a minimum of a solid 700whp now that I'll be switching tunes. Granted I do take extra care with my car and do preventative maintenance or preventative upgrades probably more than most on the platform, but my engine is at 133k stock everything at this moment. I'll be having coated rod bearings along with a crank hub solution installed to once again do some preventative modifications for higher power, but I fully plan on using this car how it's meant to be with my current setup and expect another solid amount of miles before anything goes wrong judging by past performance and the things I'll be doing to/with it.
+1 The facebook group "MMP Enthusiasts" has more details from owners.
I have MMP3's and Eugene says that unless you have a built engine the 1ks are overkill as the 3's have enough spool and power to bend rods. My mechanic and tuner both agree that north of 7 you need rods+pistons if you want longevity.

I'm a member of the group, being an MMP customer. I've had nothing good support from Mauricio. I will also say I've never seen anything negative posted on the group, and I know the posts are moderated because the last time I posted, I never saw the post hit, but received a message from Eugene asking why I needed the info I was requesting. It was an odd dialog as I was asking about v-band clamp size and was told that was proprietary info ... isn't that like saying shoe size is proprietary info? Can't any owner can easily measure and post it?In the MMP group on FB you can find much more info on longevity than in most forum postings.
Thanks for the replies. I will pass on MMP. Looking forward to what @hyand @Rob@RBTurbo release. Rob, I searched for game finishers on the forum, didn't find anything. Any links?
I found the resale of rebuilt 1Ks odd as well before ordering, and it was the one thing making me slightly cautious- but after talking to several of the people who did it, it sounds like they were expecting the 1Ks to be the same as a ST setup which they just wont be - they're still twins and inherently will be different. From what I've heard and gathered from sellers before buying, the whole "rebuilding before selling" thing has been more so the use of a benefit that MMP offers (inspection + rebuild to transfer warranty for a third party sale) in order to sell quicker and make sure the buyer isnt getting screwed over with bad turbos.What is odd is that we have seen a tremendous amount of them for sale, usually just rebuilt, since intro and that is never a good sign either. Maybe that just means people are buying them and tanking their engines and getting them rebuilt for good measure prior to moving to their ST kits, or maybe even leaving the platform due to the headaches. Not sure.
Sounds like Panzerfaust has put them through the ringer in his time with them and they are still kicking, so that is a good thing.

Its no secret here that I'm not a fan of RB or his 'advertising' but I would buy RB turbos before I touched mmp turbos again. (That sentence hurt like hell to write!)
That said, I'm certainly excited to see what the @Hydra Performance HP800s will be doing on a regular N54 or N54 with N53 head vs Omar's amazing but likely-forever-one-off engine,
I ran the original MMP stage 3's for a little less than a year before they were smoking regularly. First 3k miles were ~24psi last 3k were 26-30psi. I would occasionally see smoke on decel after only about 2k miles on them, didn't think too much of it until it became the norm when decelerating and even sometimes at idle. From MMP's request went thru the whole list of bullshit (3 different PCV systems, high flow drains, multiple different oils, etc.) finally put a newer low-mileage motor in because I/MMP was convinced it was the valve stem seals. New motor in, same exact issue. Finally pulled them off and sent them into MMP for a rebuild before selling them.
While I 100% wish I went single turbo from the beginning, I did enjoy the MMP's when running well/not burning oil. Put down 640whp on 26psi e60 fuel, ran 11.7@130 and 159 in the 1/2. But overall they were not worth the hassle, and if someone asks I would recommend a more well established, higher volume seller like the ones mentioned in this thread. But - I've never been happier with the car after going single, even if the powerband or response isn't the same
