What rpm did it start coming on for you? If you have any dyno sheets or videos please share them.

 

I don't have any videos. Litterally had the turbo on the car for about 3 weeks and changed back too my 6466. Car was street tuned so the dyno numbers where vdr and i dont have the graph. If i remember correctly i was full boost around 5k.

 

I did some digging around and found some comparisons between the older s200sx 7670 (Pretty much an s257sx NON e) and the gtx3071 as well as gtx3076r. I'm not sure if they're gen2 garrets but the numbers are pretty amazing considering its not an SXE. Also the AR sizes are different for each turbo being compared and well as designs......sooo take it with a grain of salt I guess. There's over an 1000 dollar difference just between supercores of these turbos, yet they're this close in performance. People need to stop talking down on borg.....







Green = gtx3071r .63 Blue = gtx3076r 1.06 Red = s200sx 7670 1.22 The gtx 3071r is on a 9 so it has MIVEC which does help




A better comparison would be a 7070 to a gtx3071r and a 7670 to a gtx3076r but you get the idea.

 

Just got the car tuned yesterday by slowpoketuning. On a mustang dyno the car made 510whp at 30 psi on E85 with a catalytic converter, the ****er is fastttttttt. It made aslo 430whp at 25 psi on 93. I'll post the dyno graphs later. I deff do not regret buying this turbo, if I could change anything It would be to use a t4 twin .82 AR housing or a .63 t3 housing instead of a .82 t3 hosuing.

 

It is not a bad turbo at all for the price. I still think that it needs more than a .82ar though just to help with back pressure. Otherwise it spooled quick and made decent power on my setup.

 

Those numbers don't sound a whole lot better than an FP red.
How does it spool?

 

Spec'd out its pretty close in size to an fp red.

 

I'm coming from a honda, a turbo b18c making around 350whp. So I had another 1000rpm to play with up top, and wheel spin to help me feel a like I was in the powerband a little longer. So I'm not really used to how this feels. But honestly I only have 4-3.5k of rpm to play with on this setup, I'm definitely going to try using a t3/t4 twin turbine housing/manifold later to improve it. As of now its pretty lazy, it hits full tilt around 4.5-5iksh but boy it comes on hard. The only reason I went t3 was because I had a brand new ceramic coated full race manifold lying around. But hey I mean If you're a driver its fine, I've been clapping cheeks regardless.

 

Both the 93 and ethanol maps are layered. It comes on a bit earlier than this on the street, I'd say at most 500rpm sooner.



I'll upload a pdf when I get it.

 

300wtq at 5800. Woof....

 

Thats not the turbo's fault....... If you use pretty much any turbo this size with a t3 housing that size you'll see this result. Also its a stock block so I'm fine with the tq being that low. Its not like torque wins races........

 

Where the car makes 300wtq is a good indication of when the useable power starts. And torque does win races. Engines produce torque. HP is just a calculated figure.

And no, it's not where any turbo that size would spool. You can put a Precision 5858 or Gen2 5558, or a Garret GTX3076 on it and spool quicker and make more power. I don't see this turbo as a good option.

 

Depends, drag racing, and roll racing is all I'm using this car for, so it'll do fine. Yes those turbos above would spool a few hundred rpm faster but for the cost its not worth it. The proof is literally in the pictures posted above of this turbos inferior predecessor with the right turbine hosuing flange and AR size out performing mine. I gurantee you with a twin scroll setup this turbo would pick up another 1500rpm of usable power or more.

 

Here you can see a gen 1 gtx3076r virtually identical in spec, same flange and AR size and mine. Yet its being out performed vastly by a t4 twin with a 1.06 AR across the board. Granted its a tubular vs cast, and this is a dynojet so it will read higher, But you can clearly see that even at 400whp its beaten entirely because of the turbine housing...... So like I said before it is not the s257sxe's fault torque is that low.

 

Hummm nice! Looks like the twin scroll is around 800rpm quicker to full boost.

Horsepower is king, you can make 1000 ft/lbs of torque with a 5 hp motor...... but you will only have 26 rpm.
Not gonna move anything very fast with that.
