[rocksandblues]

relatively new.
Have lots of upgraded parts ie: cooler, catless, intakes, JB4 (i know mhd-dragging feet), etc.

turbo wastegates are rattling themselves to death. one or more has gotten stuck open twice so far...

what is the current consensus on upgraded turbos? brand? how big to go?

[Jeef]

Want stock power levels or something more? Goal in mind?

[rocksandblues]

i am already over stock... so more

i see how this n54 thing can be a $$ rabbit hole

Don't know the level where i will have to upgrade fuel pump and or injectors.

thx

[Aceway]

Hard to suggest what if you don't have a hp goal. If you don't want to upgrade anymore parts just stick with oem or stage 1 twins.

[woodex m.e.]

Doc Race 6266.

Done.

[Riceball777]

Pure stage 2 twin turbos.

[rocksandblues]

Thx guys. Looking up suggested ones

I would like to be around 500 I'd say. Having trouble hooking up now at 400+

[zomski101]

MMP stage 3 and fuel-it stage 2

This guy gets it.


OP it depends on power goals and what fuel you have available 93 or e85.

VTT and MMP are junk, go with pure or RB if you want stock style twins. A single turbo will be more reliable and allow more peak hp especially on pump 93. Costs a bit more but do it once and do it right.

Rob Beck. He's been probably making them longer than any one for the N54. There's something to be said about that.

Anyone heard of Frankenturbo?

If single which one? Assume it will come with all plumbing to go from 2—-> 1

If Frankenturbo is on the table just get some Chynesium ebay turbos (17t). I'm in a large WhatsApp group for 335i's where about 10 guys are running the 17t ebay turbos and haven't had issues so far. One or two have more than 10k miles on them without complaint.

If budget isn't a concern and I'm paying someone to install I'd go single turbo. There are a couple of decent ones to choose from. I'd look at doing a top mount setup, which will cut down on labor cost down the road if and when you need it.

If budget isn't a concern and I'm doing my own wrenching I'd go bottom mount turbo.

The RB Evos or Pure Stage 2s are a good twin option for either of the above scenarios.

If budget is a concern and I'm paying for labor I'd get a more reliable budget option from one of the big names on this platform.

If budget is a concern and I'm doing the install I'd get the ebay turbos, personally.

My recomendation is if you want a little more power with less work and less money get the upgraded twins. If you have the money and time and knowledge to throw a fat single turbo kit on then do that.

Frankenturbo is shit. Go read the huge thread on this forum before he left for facebook where he can control the narrative 100% and it is basically impossible to search. Too many documented failures for my taste. You can buy the same turbos he sells on alibaba but without the frankenturbo pice tag. Exact Same Turbos.

Guy is a piece of work.

https://www.e90post.com/forums/showthread.php?t=1222395 <--horrific graphs, bad practices, people told him not to crank timing through the roof and then he blew his motor. He also stated inlets are not worth it on stock turbos which is 100% FALSE. Huge gains, given their cost, with inlets on a E85 tune. Guy is just an idiot.


Yes all single kits come with everything you need. Just be ready to spend 5k for a quality top mount like ACF. Docerace is meh, really long runners, poor wastegate placement, doesn't fit AWD, lots of install issues that have been documented etc.

If you want to be at 500hp, you will need:

Upgraded Turbos - RB 1's or RB 2's - ? HP (maybe 30-40hp)
MHD stage 2+ (55-60hp)
NKG plugs 2 stages cooler plugs gapped at .018
Eldor Coils
New Vac lines
1.75" inlets - 20hp
1.5" - 2" outlets / ? HP
5" or 7" FMIC - 25hp
CATLESS downpipes - 25-30hp
Upgraded CAI box or cones of some sort (AFE) 18 to 30hp

Too much richer math in here

Also I wouldn't run a ots map on shiny new turbos, especially sicne you would probably have new inlets on them and no ots maps are built for that

[rocksandblues]

thanks guys.
perfect knowledge, learned a lot

have everything on the above list except coils and plugs and jb4 map5 instead of mhd

leaning towards the pure's w research

i will need to get some serious rubber set up somehow. even now my traction control gets a serious work out.

this is a e93, bought super cheap- not sure how much $$ to put in her.

Rob Beck sells his turbos with inlets all the time. I don't think he would warranty them and sell his own inlets with them, if they would cause a problem. In fact he highly suggests you purchase inlets with the upgraded turbos.

The OTS maps are not made for inlets and outlets. There may be issues. A custom motiv tune is $250 anyone past FBO should have a custom tune. That is what he was getting at.
