here is an R34 we did with the twin EFR's (i wish those comp covers were available at the time for the rear turbo)

 

Don' t know if this is the right place to ask this but i need a little help since i don' t know how to read compressor maps
I'm looking to buying a new turbo for my FD and really am looking into the new SXE line since i think the EFR is a bit too expensive..

I want a responsive turbo, Since i mostly drive my FD around town and make a few highway miles every now and then..
I'm looking for a turbo that boost hard in 3,5 - 4k RPM range, i'm shooting for +/-500HP range (on pump!, since E85 is too far away from me)
My engine is stock port and i would like to keep it that way, already have converted it to a single turbo but i want something new with a bit more power to play with.

Which SXE would you guys advice me to reach the +/-500hp and what changes should i make to my setup in order to make this work..

Current setup:
-T04s
-HKS wastegate
-Twin scroll manifold
-1600sec /850pri injectors
-HKS twinspark (i have AEM smart oils with MSD wires ready to install)
-Exedy Hyper single w/ Jun lightweight Flywheel
-Kaaz 1.5 Diff (not yet installed)
-Radtech V-mount
-RW Throttle body (not yet installed)
-RW Intake (not yet installed)
-044 pump
-Apexi power FC w/ OLED commander

i have a methanol injection system i could put in my FD currently sitting on my shelf (debating weather to install or not)

Again sorry to do this here.. but saw this topic and though maybe someone here could help me, the person that helps me read understand compressor maps etc and answer my questions i'll buy a pack of beer for the time i'm very eager to learn!.. pm's are welcome or email eplusz@gmail.com
Thanks guys & excuse me if my english isn't top notch i'm dutch

 

Very clean. Also, sup with those T-Bolt clamps? Are those ridges functional or just aesthetic?

 

Those are Murray clamps.

The wavy section is a spring so it keeps constant tension on the hoses and even tension around the circumference of the clamp. They don't get loose with heat cycling and they don't pinch the hose in one place like T-bolt clamps.

I used those on my FD and they work awesome and have an kind of a clean/OEM-ish look compared to T-bolts.

 

Any thoughts on whether we will ever be able to get the T4 Internally gated twin EFR housings for the SXE's? Are they even compatible?

 

Not compatible at all, and I am pretty sure they are staying an EFR only turbine housing.

 

shut your mouth! you mean i can't use these together?

BorgWarner S200SX-E Super-Core UNIVERSAL

BorgWarner 7670 Turbine Housing UNIVERSAL

says both are 70mm od turbine, have you tried to mate them?, what doesn't work,,, im ordering both and will report back if it's impossible to make it work,... impossible by my standards at least

 

@lastphaseofthis - its not going to work, sorry

 

i'm ready to attempt to put the s200sx-e in to a stock s5 turbine housing.. that will require machine the turbine housing to fit the 70mm..
surely starting with an EFR turbine at 70mm would be a better start...
understanding they will not bolt up, what does it really look like.. those who have the turbos in your hands .. why. what doesn't fit, the depth? will i have to machine a different snap ring? the turbine hits the housing??

i guess i could order the s200 turbine housing and try making that into IWG.
