Yeah, i havenít decided what i want to do about filtering yet. Iíll cross that bridge when i get to it. I may have a flange made up at work or even just weld a lip on and be done with it.

I'd go bolt on long before I welded to the housing.

If you have a basic machine shop, you'll be well covered. I'd look at making a large bellmouth for a shallow filter, similarly to the Vibrant set up below. Simple lathe bellmouth with three bolt holes. If you aren't happy with it, it's easily reversible.

That was my hopes initially. Something removable that could accept a filter or a turbo guard. Iím sure i could find someone around here to fab something up. I mean, a bare bones setup would just need an adaptor flange machined and then weld a lip onto the flange that would accept stuff.

PDX, why'd you sell your full race headers?

Nothing more than personal issues with full race. Great header, just wanted my car free of full race parts. Silly I know... but it felt good.

With all the talk about fabrication work, I figured I would summarize some of the pieces that helped me assemble my turbo kit. I fabricated a new uppipe and downpipe to fit my twinscroll 7163 in my car. I utilized the twin scroll header that came with my Spec C Type RA drivertain.

I bought one of these twinscroll uppipe flanges from Moore and cut it down to match Schedule 10 304 - 1 3/4":
http://shop.mooreperformanceparts.co...i-7470057.aspx

I also bought this Schedule 40 to T4 twinscroll flange, welded inside and ported to match the schedule 10:
https://roielinnovations.com/product...al-1-5-sch-40/

Then made this:


These are a godsend for sch 10 header fabrication work:
https://www.icengineworks.com/produc...-clamps-set-4/

3" 'Cold air' intake was made that routes directly to passenger fender:
2.5" to 3" silicone adapter, 3" 45 and 3" 90.


3" downpipe, also utilized the IC Engine Works clamps, just the 3 inch version:




I'm using an AWIC intercooler with a vanjen clamp welded directly to the throttle body.

HA, those clamps are cute!! I'd always just used hose clamps were I drilled holes into the band for tacking spots.

Those take things to another step.

Nice work.

I like those clamps. I seen another IC engine works product for making exhaust manifolds, they are basically legos to mock up the manifold before hand. Pretty handy items.

Hey guys, excuse me for not being completely current in this thread (Iíve read up to page 93, almost there!) but Iíd just like to go over what Iím hearing and get some feedback.

Thereís clearly a decent difference between the guys running EFR 7163 with Full Raceís stock location IWG and those running rotated EWG setups. It seems like these rotated cars are doing slightly better with power and spool when comparing similar cars (hard to do because FMIC/TMIC and SAVCS/DAVCS) as are cars that have some port work done to the heads.

So it seems like the best (in terms of cost per gains) option for a rotated EWG setup is to leave the heads stock, especially if itís a dual AVCS car as these seem to be spooling the best. For the Full Race cars, it seems like the benefits of porting heads and adding a decent cam are evident.

Here are 3 dyno sheets Iíve got to compare. All 3 of these cars are single AVCS, Full Race IWG cars with built bottom ends, FMICs, and some sort of head work. All running 27-28 psi.

http://imgur.com/S863QBw
First is a GC with an STi swap, bowl blended +1mm valves and GSC S2s. Also 9.1 CR

http://imgur.com/l6994js
Second is Jagers STi, with SoCal porting headwork and GSC S2s

http://imgur.com/IfgdttB
Third is an STi swapped wagon with no mentioned port work, +1mm valves, and GSC S1 cams.

All of these cars appear to have been tuned at Yimi. This makes the comparison a bit better for numbers sake, although conditions vary and they are all set up differently. Bottom line here is: for us guys with the FR kits, going through stock inlets and dealing with the IWG, whatís a well-suited cam/headwork to get these turbos to perform at their peak? Clearly theyíre capable of around 550whp in the low 30s of boost, but what best facilitates that?

Maybe Jager will chime in with the reasoning for the work they did on their time attack car

I guess you need to define peak. Are we looking for best spool, highest power, flatest torque curve, etc...?

Thatís a good point, probably shouldíve defined peak.

On the FR stock location setups especially, spool looks great but power falls off up top. Iím guessing this is a result of being restricted by the stock inlet and stock cams. Of course also taking into consideration that the turbo is at the limits of its efficiency here.

My setup is a Full Race stock location EFR 7163, built bottom end, ELH, FMIC, etc - all youíd need to max this turbo out on E85. Itís sucking air through a 2.4Ē inlet and stock single AVCS B25 heads with upgraded springs. My ultimate goal is to not ruin the beautiful spooling characteristics of this turbo while preventing the power from dropping up top. So Iíd say a balance of best spool and area under the curve at higher rpm.

Of the three graphs I posted, Iím looking for a curve most like Jagerís STi (of course, the time attack race car lol). Just trying to determine what kind of portwork and/or cams can get me on the right track.

Also having thoughts about a custom 3Ē inlet, but since the compressor housing only has a 2.5Ē inlet, I figure itís getting choked regardless.

for me, my goals were fastest spool while still retaining fun factor. The 7163 fits that bill perfectly.

I really should get on a dyno, but the one I dyno'd my stock turbo on went out of business so the number doesn't really mean much.

comparing cars on different dynos is difficult unless you compare all the cars on a dynojet.

anyone here install a speed sensor in their EFR? I am wondering if I'm overspinning the turbo since I run 27 psi but I'm at 5500 ft altitude.

I agree with you. All the dynos I posted were done at Yimi, which is why I chose them specifically. Still each setup is unique.

Your setup sounds ideal, but thatís a dual AVCS rotated EWG setup if Iím not mistaken. If I had the coin to do it differently, Iíd for sure go rotated. For now, Iím looking to help the 7163 flow better up top while sucking through a stock inlet. Solution will likely be porting and GSC S2s, or no porting and S1.

If youíre feeling bold you could try Matchbot, but Iíd say at that altitude youíre probably border line. Especially if youíre holding that boost in high RPM

Correct. 2012 Sti so DAVCS. I dont blame you wanting to stay stock location. my original plan was to run stock location with an ETS TMIC.

Then I decided that the cost of Full Race stock location kit was too high for what you got, and the ability to ditch the inlet was ideal.

I did a matchbot with as much log data as possible. I was 28psi at redline, and off the map. Will post link here in a few.

Itíd be easier with a tmic for sure. Whatís holding me back is that I already have the front mount setup and donít want to get custom fabbed piping at the moment (just got all piping powder coated). Plus, thereís no upgrade from a 7163 in a rotated configuration. Everything would need modified if youíre going to a bigger EFR. If I were to go rotated Iíd do a 7670. Thatís the only reason Iím stock location. That, and my buddy made the up pipe and downpipe, so I didnít pay the full race price.

Inlet restriction is definitely apparent, no way around that in the stock location. Hopefully I can find a good head/cam combo to compensate..

Time for an upgrade? Lol. Someone did a matchbot earlier in the thread that reported similar results to what PDX just mentioned.

I have material here that you can use to make a custom 2.5 - 3" intake adapter for your 7163. It slips right on the inlet cover. I'll send you one for the price of shipping. All they are is skateboard wheels, and you'll hog out the center with a forstner bit.

They have a durometer reading high enough to handle the heat. I can take a pic of the one that's sitting on my 7163 right now, after a lot of use.

Another key, IMO, is the intake filter. Make sure you get a filter with a 6" opening and put it on a velocity stack style intake fitting that then connects to a 3" pipe.

You can also see some of my best graphs a few pages back. I got better spool and redline RPM by ditching the BW wastegate can, and going with a high spring turbosmart one port.

Here's my attempt at matchbot. The only thing I'm sure about is the data I entered came straight from a log. Other info may be off, most of it I left as is unless I had the data.

I'm also hybrid MBC so note the WGDC data may be wacky. I forget the details on what I did with those in matchbot. I just remember having to play with them.

Yes. I did not realize that with the V-band there is no way to upgrade to a 7670 or 8374. I'd need an entire new kit.
