Good Afternoon TLA,
I was wondering what is the turn around time once you receive the cores and do you rebuild them as well. As in new internal hardware, bearings and o-rings things of that nature or is that extra cost?
Thanks for your time,
Eddie Ramirez
Im still working on finding replacement parts for the internal WG hardware problems. The rebuild includes o-rings, bearings, seals are already included in the cost.
Have you found a wastegate problem fix for the turbochargers? If so when will you be ready to include that in your turbo rebuilds? Id be interested in getting my turbos rebuilt by you if could include the wastegate fix for my 335i
I currently dont have parts to fix this problem yet. i am trying to remove the bushing that holds the arm so can get measurements. I tried pounding and pressing it out. im thinking that the housing must be heated to press the bushing out, Because the Nickle housings swell and trap bolts in the MHI evo3, evo 8, evo 9 and evo 10 turbochargers.
I am Intersted in the upgrade. My turbos have 75k no oil leaks and according to 2 different dealers my westgates are fine (little noise) it’s 2008 updated design. What is the turnaround time for this job. And what kind of ho gains can be achieved with this update. With proper tuning of curse. Will the turbo be able to handle and provide more boost at oem shaft speed for example ???
All wheel drive motorsports claims 400 hp, but i have heard of people making that out of the stock turbos. I didnt realize there was a updated Design. It seems like it is common for the Pull type wastegates to have more problems than the push type. We do the upgrade for 750$, which includes the billet upgrade that is 5mm larger than stock and the turbine wheels we have clipped, and we rebalance the assemblies. The Boost level is controlled by the Wastegate, which is often controlled by a boost controller, but im not sure how it works for the bmw n54 turbos because the wastegates opperate on vacuum rather than boost. it may work the same way with the boost controller.
I have a 07 335i, my wastegates and my seals are bad how much would it be to upgrade it and work with my dinan software? And what it the turn around time?
I can r build them for 650 and upgrade them for 400 more. I don’t work on software.
hey austin, pulling my 535xi wagon turbos right now, will send them two you monday, to rebuild and fix flapper (no upgrades, cant imagine it being any faster then it is now running poorly) question, online manuals etc, say to discard all of the torx and other fasteners required to pull the exhaust, lines, and all the other shit to get to the turbos.. who do you recomend for all of those,,, gaskets etc. i found this one but unsure if it has it all https://www.ecstuning.com/BMW-E60-535i-N54_3.0L/ES2501019/ is there other stuff you recommend to replace while im under there…
used pelican parts tech guide to get them out,, what a pain
thanks pc
Looking to upgrade my 335i turbo’s (N54), ran across this post. How’s those Greddy cores coming???
I have a 2008 BMW 335XI coop 100% excellent condition. Just rebuild rubber boot on frone end brand new tires full leather showroom status. What I do not want to do is to give a way the car. I’ll rather have the sticky wastegate problem fix. Maybe sale it or drive it. Manual six speed is so cool and places all the power under the drivers control. What will it take to get wastegatee problem fix. May be a rebuild but that’s it.
A Targeted Individual is someone that has been selected by the Deep State (usually FBI or CIA) to unwillingly participate in a government experimental torture program. This program is designed to break down the individual and “neutralize the person,” using psychological, physical, and emotional stress. The ultimate goal of this program is to control the entire global population. Political activists and whistleblowers are two of the main targets. Family and spousal relationships are usually destroyed, as part of this torture.
