It might be too late to ask this, but do you guys think the EFR 6758 is too big for the RB26? I'm like neck-deep in the build now, so it's probably too late to turn around, but curious what you guys think. I got them super cheap so couldn't pass them up, so this is my life now. 

I'd like to check out this build. There's gonna be some sick parts to support these little guys. Do you have a build thread somewhere?

I do not have a build thread. But I could certainly make one. I'm not doing the work myself, so some details/pictures might be lacking. Let me throw a thread together some time this week and I'll let you know.

Here's some updated pics

Nice!  Very very interested to see how this goes, those are capable of some huge power   When do you aim to have it running by?

[damuscat]

Ditto! Looking awesome so far

First start up is on Friday!

looks good!  only question is regarding the intake tubes/filters - are they 3" ?  or 2.5"

I'm not sure. I can ask. Would it make a difference and if so, what should it be?

[Full-Race Geoff]

Ok - I prefer to see 3" as the smallest diameter for the inlet. 

 

edit:  the 2.5" will work fine, but 3" can better avoid any surge with 7163s

These are 6758's, if it makes a difference. 

[Full-Race Geoff]

ok good - 6758 is not nearly as sensitive to the surge margin as 7163.  just something simple to keep in mind since its just a 90 degree bend and a filter on the end

I'm using the turbosmart twin port actuator (14psi springs 3 turns preload) with 5.4w 4 port Mac valve @20Hz  max d.c 60% for 1.6 bar boost @3800rpm. High and Low 3d boost maps on Link G4+

Had the EFR high boost canister but it is hopeless for good control and used to severely over-boost after 20 mins driving when WOT. It was about 20mm away from #1 runner so I extended the turbosmart actuator 50mm forward. Boost control is damn near perfect.

@Meathead did you have to cut some more thread on the arm of the turbosmart actuator? My IWG actuator hits on the body of the car and was thinking extending it in this fashion would work almost perfectly i think.

[Meathead]

Actually I cut some more off leaving around 30mm of thread and added an extension which I turned up to cover the spacer width.

Is that the 'inconel' brand beanie? Did i already ask this or was it a diferent one?

Yeah I'm curious too. I have a genuine efr one to go on my 7163 and it's freakin huuuuuuge. Same beanie they fit on the 9180. One size fits.... Most

Thanks.
I assume their B2 one fits twin and single scroll?

edit: did a bit of a stalk and confirmed you have a 8374 TS IWG so it does

[Meathead]

Yeah it does the job well!

You mentioned an Inconel one, I looked at that first but gagged on the price   https://www.turbosource.com/BorgWarner-EFR-IWG-turbine-housing-shield-p/ts-inconel-efr.htm

[sneakey pete]

Hope so, mine just left Austin...

The 'Inconel' brand stuff kinda lost me at them trying to make it out like the inconel was what makes it insulate, and not that the inconcel is just the high temp protecting casing for whatever they use inside for insulation.
And also the prices

[Piggaz]

Buraz' car.

Went from a Precision 6262/0.84 to a 9180/1.05 on his Racepace built 2.8L.

"target boost" was the same RPM - 4700 RPM, however the 9180 feels much stronger sub 3500 RPM. (Yes, the bigger turbo with the bigger ass end felt stronger down low). That falls in line with a couple other 2.8/9180 results that have come through lately.

6262 made 430 rwkw at 24 psi

9180 made 483 rwkw at 24 psi and 498 rwkw at 27 psi so possibly needs a larger exhaust. It's only a 3.5 inch RP item.

* Adnan loves to rape this thing so the tune is softer than most.

Once again, the transient response is the stand out. The stuff that can't be shown on the dyno.
