your gonna have to worry about melting the motor mount.

 

Wish I managed ... Well as I told compressor on photo is same size as 7670's. I thought compressor running into a frame is what makes it no go. Core should position free, housings and wg are linked, and I believe compressor housing is free to turn as well. Wastegate ... I hope it is possible to elaborate the rod and wg mount so it goes around things... It may be as long and twisted as needed so far it is sturdy enough not to bend.

Still buying 7670 just to face the fact it cant be mounted wouldn't be pretty.

 

If you can find a way to mount an EFR in a "regular" bottom mount configuration I'd imagine you'd have people interested in it. Having the WG built in reduces costs and plumbing, and just makes the package overall cleaner. I'd say a single scroll t3 turbine housing would be the most popular.

If you're looking for other ideas, SOS makes a kit for the S2k that uses a Mitsu Evo turbine housing with an internal wastegate. I haven't seen it personally, but it fits nicely. The "problem" with this kit seems to be that the dual scroll t3 turbine housing and/or manifold chokes the top end and simply doesn't flow that well. Of course, the EFR turbos are much longer, which I imagine poses the biggest problem. It would certainly be fun to mock up a spot for it and see if it's doable. Here are pictures of the SOS kit:

The ptuning kit is designed to be used with their engine mount. When in my opinion is a huge downfall to this kit because of the increased noise and vibration caused by the mount.


Also efr turbos cannot be used on low side mount manifolds such as the ptuning/full race ram horn or any standard non top mount log due to the huge size of the efr turbos. Efr turbos can only be used on top mount or front mount/sidewinder manifolds.

 

Wow! Quite a difference

 

The draw back of the SOS kit is the hotside design. And no they do not use a t3 twin scroll setup. If they did it would be making a whole lot more power. The issue is that the use a restrictive evo8/9 style twin scroll housing design. Not a t3 twin scroll setup. Because of this this setup will loose 75-200whp on the top end depending on how much boost you run.

 

Oh I love the idea and was actually thinking of asking someone to make me manifold like this. Dump twin scroll tho for 7670 on such header will spool up like crazy either way.

 

Compressor housing clearance width wise wouldn't be an issue. Length wise it will be, look at the picture posted and see how much longer the EFR turbo is, that moves your compressor up to the oil filter area. Core does rotate freely, but you will have to take into consideration the Coolant lines for it. Compressor housing also rotates freely.. to an extent, it has to be rotated ~15* at a time to allow the waste gate bracket to still align correctly. Waste gate and rod rotate with the turbine housing, with the way you have the turbine housing sitting, it will be where your oil filter/cooler sits, and a relocation will not help.


Yea, it's actually quite impressive on how much larger and heavier the EFR Turbos are. Well worth it though, in my opinion.

Also to add for the OP and anyone considering an EFR turbo: Ditch the Borg Warner supplied Waste gate and get a real waste gate (turbosmart or billet) that do not depend on rod preload tension for boost control.

 

How about this? Actuator doesnt stick out as much as in EFR...

 

You're also comparing an EWG turbo vs an IWG turbo. They're shorter when you don't use an internal gate housing.
