ShaggyZ Posted December 9, 2010 Share Posted December 9, 2010 (edited) Perhaps the most thorough coverage of these new turbos is at Full Race - http://www.full-race...efr-turbos.html The turbochargers have been completely redesigned with some pretty cool features that, if truly functional, may justify the ~$1500 price tag. They all come with integrated Boost Control Solenoids and speed sensor ports; many of them come with well-designed integral wastegates, and the actuators bolt to the center housing instead of the compressor housing so you can spin the housing to just about any rotation you need; integrated by-pass valve (ie recirculating blow-off valve). They say these features are actually useful and efficient even in high horsepower applications and have OEM/high quality durability. I'm intrigued. The BorgWarner EFR turbo is set to become the new world standard for performance turbocharging due to the high-technology feature package, unbeatable performance, and installation convenience. The EFR turbocharger was designed and manufactured with only one purpose in mind: to dominate the street, track, and strip. (7) different sized turbos, optimally matched for the 250-1000hp per turbo segment - and in (4) different turbine housings are the result. The combination of this top-shelf geometry and the Gamma-Ti turbine wheel significantly raises the bar for performance aftermarket turbochargers. Combined with our ball bearing technology, it is the most responsive range or turbos that are available anywhere, at any price. The EFR series covers all applications except the hardcore drag racers. For those hardcore customers, we still offer the highly popular S400SX and S500SX product lines, and will continue to update those turbos during the next year. I did a search for EFR and came up empty. Edited December 9, 2010 by ShaggyZ Quote Link to comment Share on other sites More sharing options...

Very cool.Ball bearings to boot. First time I've seen them on a BW. Wish I had one. Quote Link to comment Share on other sites More sharing options...
tvgz28 Posted December 10, 2010 Share Posted December 10, 2010 I wish I had the coin to drop on that ...but I'm a poor white kid so old school hx35 for me, unless someone makes a standalone controller for the he351ve then ill be a poor white kid with a vgt Turbo.

lumberjackj Posted December 15, 2010 Share Posted December 15, 2010 Saw these in person @ SEMA this year, look extremely promising, they arent for sale yet, but they DO pack a lot of features into a nice neat bundle... For sure we will be doing testing with these things in the future! Quote Link to comment Share on other sites More sharing options...
MazterDizazter Posted March 3, 2011 Share Posted March 3, 2011 I'd like to see a comparison between the Borg Warner EFR and the new Garrett GTX series; I'm trying to decide between one of the two... Quote Link to comment Share on other sites More sharing options...
ozzzzz Posted March 3, 2011 Share Posted March 3, 2011 I'd like to see a comparison between the Borg Warner EFR and the new Garrett GTX series; I'm trying to decide between one of the two... They are still not available to the public. Would be a good comparison. My friend is sponsered and will be getting his within the week.

roger280zx Posted March 4, 2011 Share Posted March 4, 2011 I doubt Garrett can beat the $2200 price tag with all the accesories included. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted March 4, 2011 Share Posted March 4, 2011 We're going to use them on a twin turbo Z06 build simply because there is no room for anything else Quote Link to comment Share on other sites More sharing options...
jessejames Posted March 4, 2011 Share Posted March 4, 2011 I've got the efr 6258. I'm really impressed with the build quality and the packaging. I've not installed it yet as its too cold. Heres a couple of pics. http://img52.imageshack.us/img52/7401/20110121140017.jpg Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Quote Link to comment Share on other sites More sharing options...

260DET Posted March 18, 2011 Share Posted March 18, 2011 Side by side comparison is the only way to tell, until they show in use superiority I'll stay with Garrett thanks. Quote Link to comment Share on other sites More sharing options...

HK240ZT Posted June 1, 2012 Share Posted June 1, 2012 Bringing this thread back to life! Anyone running an efr or gtx series turbo on their L engine? I would like to know more. Quote Link to comment Share on other sites More sharing options...
roger280zx Posted June 3, 2012 Share Posted June 3, 2012 Is it still too cold? Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 4, 2012 Share Posted June 4, 2012 I'm planning on getting the 6758 unless my current T3/T04E (.63 hot, 57 trim cold) ends up working better than it has so far, when I tune it properly. I'm thinking my current one will be too slow for my autocross needs. Quote Link to comment Share on other sites More sharing options...
wigenOut-S30 Posted June 27, 2012 Share Posted June 27, 2012 I would like to see some data from those that have installed these turbos.. Lets see some updates! Quote Link to comment Share on other sites More sharing options...
jessejames Posted June 28, 2012 Share Posted June 28, 2012 i'll post my dyno chart when i get back from work. sorry for the delay. It should be noted that im still using the factory sr20 ecu. so it has not been tuned. it just compares my stock turbo and my new one.

calpoly-z Posted July 18, 2012 Share Posted July 18, 2012 Seriously considering the 6758 for my build as well. I'm not looking to make a ton of power, but I want a very responsive motor. I love how quickly the stock T3 responds but not how inefficient it is at higher boost levels. I dont like that the 6758 only comes with a T25 flange but I know there are adapters out there for that. To bump up to a T3 flange requires going with the 7064 which seems like far more tubo than I need. A physically smaller turbo appeals to me as well due to the fact that I've got an A/C compressor mounted on that side of the engine too that has to be worked around. Plus the 7064 is about $300 more. The ~$1500 for a 6758 really doesn't seem that bad considering there is no need for an external wastegate/plumbing (~$2-300), the intergrated BOV makes intercooler pipe routing clean and simple (~100), and the included boost solenoid is just one less thing to buy (~$40) and I can control it with MS (most likely). It was going to cost me at least $7-800 to get my stock turbo rebuilt and turned into a T3/T04E. Or I can spend an extra $6-700 and get a brand new state of the art turbo that should help me better reach my goals with a limited investment in time from me. (Time being the hardest thing for me to come by right now). Hell, I think I may have just talked myself into it. Now the problem may be sourcing one. Most suppliers I've seen so far are out of stock.

roger280zx Posted July 18, 2012 Share Posted July 18, 2012 I've noticed where you used to read "sold out" or "out of stock" I'm now seeing "ships by August", hopefully that means BW has ramped up the aftermarket production division. Quote Link to comment Share on other sites More sharing options...
