2015+ WRX EFR Turbo Kit by KILLER B MOTORSPORT

KillerBMotorsport · 02-12-2016, 04:47 PM

Based on the fantastic results we've posted with our Garrett based 2015WRX turbo kit, we've had some interest on an EFR version. I don't expect the results to be as good, simply based on the IWG vs EWG benefits of the Garret setup. Regardless, some are attracted to the packaging of the EFR and it likely will be a less expensive option vs the Garrett version with recirculated EWGs. We shall see...

We'll start with an OEM to T4 (EFR) mounted adapter. It's inexpensive and has proven to work VERY well.

in for results

I'm game as well, unfortunately as the market is saturated with kits and bolt ons it make a descission of which direction to go that much more difficult. But I love it free enterprise makes for unlimited possibilities! Keep up the good work guys!

KillerBMotorsport · 02-14-2016, 08:24 PM

I don't know if I'd call it saturation. How many kits can you buy right now?

chiddy249 · 02-15-2016, 02:22 AM

Looking good! And valuable information on the suitability of the stock header.

hopsyn · 02-15-2016, 09:21 AM

What's the ETA on the release of both the Garret and EFR kits?

I also have the same question.

So much this

Waiting on BW

Hmmmmmmmmmmm

Very interested, thanks for your hard work. Looking forward to more info!

^ Just waiting on BW

nap_22 · 12-23-2016, 09:02 AM

Any update on this?

KillerBMotorsport · 12-23-2016, 07:32 PM

Not really. We waited over 6 months for the EFR and when it showed up it had the wrong gaskets with two v-band clamps (neither of which were made for this turbo) and no fittings, adapters or lines. The install kit we were told we needed cost over $900 and again took 2 months to get. When that showed up it ad more parts and pieces that were wrong, than right and we were charged a 25% restocking fee on a bag of parts we never opened and only had in our possession for 2 days. Needless to say, I've been a bit soured on pushing to support the EFRs. On top of that, in the mean time, there's been even more data that's come out showing the EFRs are not nearly as stellar as the hype led on. We are continuing this project, and have made progress since the first post, but I would not expect any testing before summer.

Isn't the only difference between a GTX R and EFR turbo the turbine wheel, really? I would suspect that with the low mount TS setup, it doesn't make enough difference and proper matching has more of an impact.

No. Well I suppose that depends on how you're comparing them. Yes they are both turbochargers, but there are significant differences in physical size, shape, turbine wheel/flow, flanges and flange sizes (both in and out), etc., etc... In short the differences are enough that they cannot just be easily swapped.

I didn't mean form, I meant function and features. I'm aware that they aren't interchangeable.

KillerBMotorsport · 12-30-2016, 09:02 PM

Well the wheels and flow rates are different. Essentially the BW are sized between the Garretts. So there can really never be an apples to apples comparison. The dyno plots have confirmed as much. EFRs are not magic, they are in-betweens.

Harey · 01-24-2017, 07:43 PM

Could this also be used for an IWG Garrett turbo?

Which one do you have in mind?

moral hazard · 03-04-2019, 03:12 PM

Is this adapter for sale?

KillerBMotorsport · 09-03-2019, 02:18 PM

The adapter comes as part of a kit. We have had requests for the adapter separately. What people come to realize is that they still need the rest of the parts in our kit. The kit is well thought out and saves you time.

KillerBMotorsport · 02-06-2020, 01:47 PM

Is there really demand for this thing?

Jedi03 · 02-12-2020, 11:08 AM

dunno...looks freakin awesome tho! at worst if price was right I would keep it on my desk to display!

Homemade WRX · 02-13-2020, 05:05 PM

I think, unlike with the EJ engines, the Garrett turbo or OEM placement give enough the power they want, and can cap the fuel system. I also think the COTS turbos will become more popular as the platform ages, like they did ("rotated") turbos did on the EJ engines.
