- Here is a video explaining the aluminium bearing housing and the hardware installation kit you get specifically for the ally bearing housing, and why you should use it. Enjoy.

this channel is awesome, master-class level content!
Thank you David.
Just subscribed and binge watching this channel. Content is pure gold.
Info from this person cannot be found elsewhere on yt.
Thank you Meemo - much appreciate your compliment.
What a great channel! I got a crash course on reading compressor maps as well as you saved my ass on an EFR 9280 build. My current 9180 was purchased as a complete kit from a highly regarded kit builder and it came with iron chra install hardware! In putting together a new setup I purchased the same install kit for the 9280, assuming the last place knew what they were doing. Thanks!!
Thank you for the compliment - its exactly this scenario that justifies the making of these videos. Im glad to hear we have assisted you with your project.
I've always been impressed by these Efr turbos since their release. I was about to pull the trigger on a 7670 years ago but I couldn't find a turbine housing to fit my application. Now.. I could've had a new manifold and downpipe built but the cost turned me away. If I ever do another turbo build I'll be forming the process around one of these. You can run a much higher capacity turbo without sacrificing spool... These really are the best. There's a k24 civic time attack car making 900hp with a 9180, and it's got a massive power band. You just can't get that with any other turbo on the market
Exactly right Kalyn - all back to the compressor map and its width - which relates to the massive power band
"Today, you're gonna learn something." Indeed, Boost Professor. Very informative video as always. Cheers.
Thanks Eric - much appreciated buddy
Turbo direct is busy doing so much and sharing information!
Unmatched knowledge, unrivalled products, no contest! Thanks pal!
Next class would be practical application of MATCHBOT.
There apparently isn't an option for the efr7163 aluminum housings as they are 4 bolt and the bolt and plate kits you reference in the video are only compatible with the 5 bolt housings. Any reason in particular that you see why there isn't an option for the efr7163?
Thx for the video. What's the torque spec for the arp bolt ?
Also, what's the main real benefit of using Alu vs Iron housing ?
better water cooling than iron housing?
transfer heat better - yes,
lighter - yes (but what if weight is not a problem ? )
Alu bearing housing will fret over time, why not use iron instead ? just trying to weight the pros and cons of each and find out what's most important things to consider when deciding
If my current setup the dump pipe has got no flex joint, would Alu chra become a weak point ?
Glad you enjoying the content - The torque specs are 17.6nm + - 1.1nm I would aim for 17nm and be safe in the middle.
Aluminium in the correct grade and hardness (heat treated) with the correct tension load applied through the fasteners will not fret.
Pro's are cooling, light weight, and more. Always install flexible joints in any exhaust system, no matter the materials used.
Do you know the weight difference between 8474 ally vs iron cores and also for a long term road car would iron be a better option? Thanks
We havent weighed the two side by side - if you have a demand on cooling, or you live in a very hot climate, consider the aluminium option.
When purchasing an EFR7163-F(V) there's a optional SX-E style compressor housing. What's the benefit of this housing over standard? For an EA888.3.
The housing is physically smaller, and has no solenoid or DV installed -
Something that's i've noticed and thought you might know a bit more about it. Even on the high boost actuator it states not to exceed some max pressure like 35psi; If i want to run a higher boost pressure than that what do i do? Get the turbosmart actuator? Even that one has max working pressure..
The reason they state not to exceed the 35PSI rating is because the spring rate only works (compresses and moves the actuator rod) up to this pressure. Anything higher bottoms out and you will experience boost creep and potentially break an engine.....
@@TurboDirectSA thanks for the reply. Is there an aftermarket actuator/solution that will work with those higher boost pressures?
@@St0RM33 Yes absolutely - Tial make one, and there are a number of other companies who do the same - for massive boost, i would suggest using an O2 can with an ECU control to manage the valve position - pain i know, but it does work well.
@@TurboDirectSA thank you!
🤔 my EFR didn’t come with that load bearing ring and it had different lock clamps(individual ones), I purchase the plates separate. No issues thus far besides the power 😅
Just beware over time the ally bearing housing will fret.
The 6758 (alum chra) i got came all assembled but i noticed that they didnt come installed with the plates you shown. Do i leave as it is or should i invest in those plates? Been using the turbo for 2 years already.
Ahhh, just found out these plates are for the B2 frames, so it doesnt apply to the B1 frames ya.
@@dagger22 Exactly right buddy - the smaller turbos aren't as susceptible to the fretting as the weight is much less and alot less leverage being exerted as the turbo is physically smaller.
.
I purchased my efr8474 with aluminum core from your site. Would it have come with the hardware kit with the turbo?
The hardware kit and bolt kits are sold separately per part# - see here:- store.turbodirect.co.za/index.php/shop/turbochargers/turbocharger-turbodirect-s-a/179423HardwareinstallationkitEFR8474Black-detail
Thanks professor, I left the BBQ...this is much better then trying to speak to strangers who want to one up each other. Just 1 question...so if we are running the 7163EFR we do not need the aluminum kit, because it comes assembled already...right?
Exactly right my friend -
@@TurboDirectSA thank you professor
@@1atinlove :-)
Is this necessary for the EFR7163 models with aluminum bearing housing....and if so, is it available.
necessary or an optional extra - its up to yu and your application. If weight is a concern, and cooling is limited, go Ally - otherwise use the norm.
@@TurboDirectSA Apologies, let me rephrase...is the clamping ring and hardware available for the EFR7163 with the aluminum bearing housing. (which is what I have) that will be installed next spring.
Cheers!
@@grabtheremote In the hardware install kit yes you will.
@@TurboDirectSA Thanks for the reply. Happen to have a part number? All I see is the clamp kit for the B2 housings....5 bolt holes. This is a B1 with just 4 bolt holes.
Cheers!
@@grabtheremote 179423 is the part number of
The hardware installation kit
Is this a water cooled only turbine?
All turbochargers are oil lubricated, and oil obviously cools at the same time. The EFR range have water cooled jackets on the bearing housing also.
Not cheap this hardware installation kit for ALU: 150 USD!!
We definately do not sell this kit for so much -- even though you would pay alot more for ARP bolt for a flywheel for example, if you compared this to the hardware installation kit, whats the difference?
We sell this kit retail for just under 90USD in our currency -- its well worth it.
thanks for your reply!
But why Borg Warner sell the turbo without this kit?@@TurboDirectSA
@@kosditrade Because yo get both iron housing and aluminium housing options -- depending on which the customer chooses, he will need the kit. Iron housings do not require the kit.
@@TurboDirectSA I understand, thank you for your explanation.
@@kosditrade Pleasure sir.
