You're also welcome to buy my 54mm Compressor and Oil-Only CHRA w/ 74mm turbine wheel. I'm going to keep the s5 ported turbine housing (Hit up G-Pop Shop and tell them Ryan with the Rx7 sent you, Gerry will take good care of you!) and sell mine as a "supercore" as well. Honestly, for a zero mile turbo, I wouldn't mind selling it for $450 just to fund this bigger build. Just something to think about, it's hella cheap and fun to play with.
Very generous offer! I think I'm pretty sold on the efr for now.... I guess I'd rather spend the extra now and and have the turbo I want. Otherwise I'll be wishing I would have got it. I'll keep you in mind though!
question. I was thinking.....Why not just buy a complete EFR 7064 with a t4 flange and IWG and mate it to my greedy manifold? Is there some advantage to using the s5 manifold/turbine? I already have the manifold and exhaust all I would need is the efr turbo. Pretty sure I could sell my bnr and t04s setups to cover the cost. Just a thought.

greddy manifolds are for fitting greddy turbos..
that being said... it may work you just have to try it.
also a complete efr 7064 is going to be more, then if you buy the supercore, and then pay gpopshop( gerry) to mount the core into a s5 turbine housing.
the EFR turbine housing is about 400 more then the supercore, gpop does their service for less then 200.

You could definitely do this, but it won't spool as well in the low rpm as a S5 based hybrid with the EFR 7064 supercore.
The Greddy FC cast manifold is a collected design which won't spool as well as the stock S5 divided design. Its like the S4 TII design without the factory quick spool valve.
Also, the larger volume of the T4 flanges/runners on the Greddy manifold and a T4 flanged EFR turbo mean less exhaust velocity so less low rpm spool.

okay that makes sense. Sticking with my current route then.
I love this section of the forum btw. After watching the 2nd generation specific part for so long I was afraid to get flamed with all my questions.
This is all theory and you might destroy both your 7064 and stock turbo and spend a lot of $ doing it.
---------------
No reason I can see that it won't work though.
Worse case scenario, you can't *just* bore the S5 exhaust housing so you have to make a spacer that fits into the S5 exhaust housing and fits the EFR 7064 "hat" or you have to Nickel rod fill the S5 exhaust housing so the EFR 7064 will fit.
Its steel. You can weld it, cut it, whatever to make it work.

Mjhrotor- I haven't seen this either in my searches on the forum. I'll document my process here for future reference. Really if this works like is being said on this thread I will be freaking ecstatic!!
On another note anyone interested in a bnr stage 4 or to4s?! Pm me for details.

I had no plans of doing it myself as I already have a stage 4 bnr. I was simply curious about the results had it been done given the strengths of the efr line.
Thanks for the clarification I do look forward to someone giving it a shot and hopefully coming back with results.
The turbo exhaust housing is cast steel and I think the exhaust manifold is too. I can look again in the Yamaguchi book to see if they said.
That would be awesome. I could machine a steel spacer in no time, but finding a green-sand mold setup in this area would be an absolute chore for the iron. I could just run a ~3/4" 321 SS spacer and be done with it.
Rookie117, why don't you just bolt the T04S to the Greddy Manifold and retune? That should be a standard T4 flange on both of them. It's not exactly what you're after for power/responsiveness, but you just might like the combination. Don't know til ya try! You could always blame the tuner too... Some guys really understand how to make a rotary spool quickly, other guys have no idea about even the most simplistic mass flow rate calculations and shouldn't be punching numbers into a computer at all...

dude that's why I started this whole thread!! That's what I was thinking about doing in the first place. The t04s is already a complete setup with manifold, ewg, and mandrel bent exhaust. It's currently all bolted up on my parts car. All I would have to do is swap it to my car and tune. I was thinking about using the t04s and maybe putting on a different turbine tonspool quicker. OR selling just the turbo and buying a different one (preferably an efr) But y'all convinced me otherwise!!!! Which i am fine with if it is what's best.
I want to do this once and be done correctly. Not sure if I want to put the t04s setup on unless I'm convinced it will be better. I'm 3 hours from my tuner.
Also if you machine that spacer if you wanted to do 2 I might buy one from you.
t04s will be nothing like EFR 7670.
the EFR is going to feel more like you would think a supercharger would.
the t04s to me would be a waste of my time putting it on. it can't do 300ft by 3000... i'll pass. why have **** spool when you can have...so much better.

What's kinda what I'm thinking....... I just want to do this once and very done and happy.
My S5 turbo with manifold should be coming in pretty soon I'll post pics when it gets here. As soon as I sell either my bnr or t04s setup I'll order the Efr supercore. Still debating between 7064 or 7670. If they are the same size on the compressor housing I might do the 7670 so if in the future I want more power it will be there. Plus it will still spool way better than the bnr or t04s.....
Here is what I did back in 2001 and I will tell you why it is better than FMIC.
First- fully ducted.
Remove the IC and the radiator still has a completely sealed duct.
Remove the radiator and the IC still has a completely sealed duct with the opening being the front of the rubstrip that you can see is cut.
Second- full flow to the radiator, full flow to IC.
I have a 26x19" radiator wedged in there with e-fan and no IC in front of it to block flow.
You can see the intercooler and there is nothing behind it (radiator) limiting flow.
If I really wanted to make the systems awesome I could have run with a vented hood so that the IC had an actual negative pressure area to vent through when at speed and put a fan on the IC so it didn't heat soak at a stop.
Third- very short charge piping with very few bends for better spool and less pressure drop.
Fourth- more centralized mass for better handling. Get it anywhere you can.
Fifth- it looks bad *** with the hood open and subtle as hell with the hood closed.
Sixth- JDM as f*ck. I was inspired by watching Options Vids.
100% agree with Blue here... Beautifully done V-Mount. I described how to set up an ideal V-Mount with oil coolers on my YouTube channel (RGHTBrainDesign) if you're into that kind of thing. Blue covered perfectly though.
i got my s5 turbo in this week. Its the best feeling stock turbo ive ever felt, zero shaft play and spins nicely. also the manifold and turbine are pretty prestine. So thats good!
I took my t04s off today, gonna put it up for sale. What do yall think its worth? From what i was told the turbine is 1.00 a/r but not sure if it says it somewhere on the turbo?
I am still considering just buying a complete EFR internal wastegate 7063 or 7670. It might actually save me a little bit and i am pretty confident in it fitting better than it would trying to fit it in the stock location with the s5 turbine. I can buy a complete efr with a turbine .84 a/r and t4 flange to fit up to my greddy manifold. Time will tell.
I also listed my bnr today. As soon as one of my turbos sell ill have enough to buy the EFR!
I'm really not a fan of the Greddy manifold. Here's why:
1) Huge runner size in which the high exhaust velocity immediately slows down.
2) Undivided front and rear pulses which create turbulence in the log manifold and more importantly, destructive energy waves.
3) Better, relatively cheap alternatives will fully divided options
I'd be happy to buy your s5 turbine housing you just bought. Just in case mine doesn't match PERFECTLY, it'd be cool to machine another.
The easier option is always just go t4 so you have tunability options. That 0.84 A/R turbine housing vs. a 1.15 A/R turbine housing for example.
your NEXT BEST option. is the S5 turbine housing, and maninfold. it will fit the 7063. with a 1/2 exhaust flange as a spacer you won't have to grind on the turbo compressor housing.
Not sure if im willing to drop that much coin.....
I guess my concern with using the s5 turbine housing with the spacer and manifold is if the spacer is going to cause more problems than its worth. Will the downpipe still fit? Water/oil lines? I guess for now im continuing with that plan.
If anyone is interested im selling my bnr for 700$. And my t04s setup for 1200$ complete with manifold, wastegate, and downpipe. All a perfect fit for FC. Heres a link with more pics.
