Here is the Dyno Video...

Aaron parker Fd3s EFR8374 Drift car dyno tune by Abel Ibarra - Taming the Wolf - YouTube

If anyone knows how to embed the video on here please feel free to repost!!! it would be much appreciated!

Now The dyno chart is a bit off because we started the pull late instead of 100% TPS at a lower RPM to get a full Accurate pull But were going to see if Lucky seven can send the print out of the Last dyno pull. But just to get you guys a nice idea.....here is a Shot of one of our pulls messing with the EBC settings..20lbs at 4K RPM!! And I think we can do better by messing with the Duty Cycle!

Gotta love how Rotaries spool a turbo

LuckyX2

Here, I posted the vid for you. Use the YouTube tags (YT or YTHD) and in them put the part of the url that comes after the equal sign. Your video was "RKeNiGs5nSc" for example.

Awesome pull btw. I love how it's so calm and then instantly, BWWWWWAAAAAAAAAA. Talk about throttle response... And you know it's good when it blows the ceiling apart in the dyno room

Well, the 7163 equipped Jager Racing/Yimisport STI just took not only the Street Class win but also the overall win in the Redline Time Attack. I'd say there's something to this whole EFR thing...

Which btw, mine just came in today fresh from Full-Race. I'll post pictures soon.

I had it delivered to my dad's shop rather than the house. Kinda busy prepping for an interview so I don't think I'm gonna make it out there today. Pics tomorrow and installation within a week hopefully.

lol, sorry for the delay, I didn't get out there until today.

What's in the box?!


Oh, just an awesome turbo


Shiny billet compressor


Side view


Closer look at the mixed flow TiAl turbine


Divided wastegate


Manifold and downpipe too


This manifold is perfect




Big thanks to Full-Race for being an awesome company with the highest quality stuff and to Def for throwing together a group buy.

I'll hopefully have this installed within a week and can do some datalogging. Don't expect any dyno pulls soon though, I'm leaving for a cross country drive mid August and will be gone for 2-3 weeks.

Interesting to see close up photos of the mixed flow turbine! Besides wastegate flow, does the rearward volute provide both radial and axial turbine flow? It's hard to tell from that angle.

LuckyX2

I'll pull the turbine housing off soon and get some more pictures. Until then, there's a picture in the first post that shows the turbine differences.

Started putting the 7163 on today. My oil feed isn't as long as I thought so I'll need another, I snapped an exhaust stud and the downpipe doesn't want to line up with the turbine outlet. Typical issues...

LuckyX2.... I was hoping you would go through with it. Just... freakin awesome!

I'm so looking forward to see dyno results for this. And even more to hear about your first driving impressions.

Would love to change this for my 6258 one day

LuckyX2

I'll be sure to post my impressions here as soon as it's up and running. That might be a few more days since I ran into some issues like with the downpipe.

How do you like your 6258? I imagine it's a lot of fun.

Hope you can resolve that quickly. Good luck with that!

The 6258 in combination with a stock SR20DET (except for poncams) is really great to drive. Compared to the GT2860RS .86 I drove before that, it feels very N/A'ish and holds power on the top of the rev range much better (as expected ). Perfect combination for your everyday street car.

I somehow hope that the TS 7163 you just bought won't spool up that much later than the 6258... I know, wishful thinking..

I can vouch for that, I don't have my setup tuned yet, but it is way better than my hybrid T04E/T28 setup. It also fits with the stock exhaust manifold, banjo fittings for water lines on block side and you have to grind the block a little to clear the V-band clamp, but it is at the gearbox bolt so no biggie



It's stock

Does the BCS fit with it on the stock mani?

The gtx35 was t3 twinscroll. (Ar:?)
The efr is t4 twinscroll

The flange is the only thing they switch from the set-up

Its on a sr20vet btw

No, you would have to mount it on the body or anywhere else you find suitable.

Any pics of what you have to grind off on the block?

Wonderfull setup Motary, post more pics or link to your build please.

LuckyX2

Can someone buy THIS, please?

$1300 for a 7163 is ridiculous.

Well, it's gonna be a little while before I get this thing running now...



That's the banjo bolt for the oil feed line and yes, that's the threads from the block broken off in it

Either going to helicoil it or thread it out to 1/4" NPT since that would be just a little larger than the M12 bolt that was in there. Not sure yet.

Also, I have no idea how the intercooler piping is supposed to fit. I bought THIS kit and absolutely cannot see a way it would go together. I'm starting to think they sent me the wrong pipe actually, the pieces are different than in the pictures. Next skill on my to learn list is definitely welding so I don't have to deal with stupid things like this.

In good news though, I got the downpipe to line up after loosening everything and going back at it. Probably a leak from it not lining up right where the downpipe meets the exhaust but I don't really care. It's after the turbo and after the O2 sensor, so whatever. So once the oil threads are fixed and I get some piping that works, it will be good to go.

If anyone reading this is in east PA, I definitely recommend Nyco for any of your fitting needs. I walked in with my old bottom mount oil feed line, told them I needed the same thing but twice as long and $36 and 15 minutes later I walked out with this:

Very pleased with Nyco.

Update, the install is VERY close to being done. I just need a 45* or 90* fitting for the coolant feed since the wastegate actuator blocks a straight fitting.



Tapping the oil feed to 1/4" NPT went smoothly. Time consuming, going just a turn or two at a time but no issues.



Even got my eBay piping to work



For those considering this pipe for a top mount, here's the pipe I had to cut and how much I had to take off. I needed to use one of my own 90* elbows too, since it wasn't supplied.



And here's the finished product:

Looking very good!

LuckyX2

Well, she finally runs. Here's a little clip of the boost recovery for everyone. 3rd gear, about 3k and I floored it. Let off the throttle after it got into boost a bit and then got back on the throttle and it was right back where it left off in an instant.

More info soon.

It runs!

When you're in 4th gear and you floor it from 2k RPM upwards, when do you reach 1 bar of boost? Could you upload some more footage (just some runs, driving around town etc.)?

FullRaceGeoff

great comparison, twinscroll vs. twinscroll. Do you know if the gtx35 was a 1.06 a/r or 0.82?

I will try and attach some photos of this right now

the stock manifold's cyl #1 runner is a bit too close

looking good! have you had any more seat time lately


I agree, the 6258 and stock-ish SR20 is an outstanding combination. It feels like there are 4 more cylinders under the hood. Easily one of my all time favorite combinations due to the simplicity and ease of this setup. People are often worried about not making big top-end HP and tend to go right to the bigger turbos.

singlescroll 7163 will usually spool about 800rpm later than 6258 singlescroll. The twinscroll 7163 will cut that down to around 350-400rpm later than 6258 singlescroll.

bang-for-the-buck a 6258 on stock manifold is hard to beat


nice!

Nice pics Geoff.

What's your idea on relative spool/power differences for a 6758 on a ported stock SR manifold vs. a 7163 on a Full-Race twin scroll manifold? Figure the usual cams on an SR20DET.

I'd think the 6758 would spool up a tad quicker due to the lower wheel inertia, and less manifold volume and shorter runners. Adding up to maybe 200-300 RPM? But I imagine there's a solid 50-70 rwhp difference up top with a higher flowing comp/turbine wheel combo plus better flowing turbo manifold.

Thoughts?
