And just so I dont hear any excuses.......Here's one scaled to the BW's plots....
Key points:
-Look at the effiency areas within 72%
-Look at the Choke Line
-Look at when the pressures max effency is achieved
-Look at the max effiencies
GTX wins in all of the above
I'm not trying to say the GTX line is superior to the ERF's in every way but with this turbo it looks to be. I like the EFR's a lot but just because someone can show one singe ERF marginally out performs a GTX doesn't mean they've mastered every size and trim. Seems a lot of the miata crowd has became ERF fanbois for whatever reason.
I would suggest to just keep an open mind.
[sarcasm]Man that 6758 looks great, compared[/sarcasm]

An s2000 will make on 12psi what it takes an EVO 25. Our BP's aren't even as efficient as the 4g63 let alone a honda. So we're back to square one.

The GT2871R sounds like a decent turbo for me. It doesn't break the bank, it's ball bearing and oil+water cooled... Correct flange. Right? The GTX no doubt is a boss.. but.
"Turbine wheel is cast from "Inconel" material for extreme applications Direct upgrade turbocharger for GT2860RS (PN 739548-1) 743347-2 features a high boost actuator adjustable down to 12 psi 743347-4 features a low boost actuator adjustable down to 6 psi"
And why doesn't Garrett show a GTX28 anything on their site?

Please, tell me how you justify this with the topics below in this comparison? Lets stay turbo specific here we're comparing 67mm compressor wheeled turbo's not a line of them(like you ignorantly did above). I only expect another stupid a$$ comment with no justification like the one above but please prove me wrong.......

As 18psi stated earlier, I'd be a bit worried about welding/hacking up the Begi S4 manifold as it is a thin walled stainless unit and it's survival depends on the nicely done exhaust braces. GTX might a great option for you in this scenario.
No idea on why Garrett doesn't show anything on the GTX, but ATP sells them.
In fact, you can buy them "less turbine housing" like the 2871 upgrade. Same process, just unbolt the CHRA and slide the new one in, lol. However, you're going to have to spend 1300 bucks.
That's my only beef with the T2 turbos, you're going to have to spend some serious coin to compete with the T3/T4 footprints. But, if you're looking for ease of install without changing any of your current parts, you can't beat the GT2871 upgrade or the GTX2860/2863/2876
The only advice I can offer, if you're planning on sticking with T2 and your current parts, is to do as much research as you can on the GTX turbos. The GT2871 is highly documented on this site; there is virtually nothing you can't learn about it on here.
Stop crapping in this man's wonderful thread. Holset.

Nope. Andrew is making 350@14psi and something like 400 or close to it on higher boost. Or did you mean pump gas, cause he's on e85.
Also keep in mind that 80% of the people on here never really push their setups. Most don't even dip into the efficiency plateau (like yours truly with the previous 3076 setup). Its just not how people do things around here: everyone's conservative
If you pushed the 71 past 20psi, I'm sure you'd make more than most just because you "went there"
I mean Fae would be a "pioneer of high boost" if he actually kept his car running longer than 1 week at a time.

1) New tubular Mani with vband and GTX2867 with tial exhaust housing
2) Use same Mani with a V-band adaptor and GTX2867 with tial exhaust housing
3) EFR 6758
4) GT2871 conversion
5) Some used turbo that will get you to your power level but will lag more than the above.

True, and I completely support that train of thought, the thing is: you mentioned spool being important to you, and I'm getting the feeling that you're trying to retain as much of your current setup as you can.
Had neither of those been priorities, I'd be suggesting you go 3071/3076 and larger right now with a ramhorn manifold, ewg, etc... So you can make 400 without much effort and go to 500 if you so desired.

The car wont ever be a good drag car - My power to weight ratio has me at mid to low 11's but I probably couldn't get below a mid 12 in the 1/4.
On the street - I'm running down modded M6 BMW's, Z06 Corvettes with bolt ons, 540 RWHP turbo G35's, and 475 AWHP STi's.. But I'll loose my license in a month if I keep this crap up.

Turbo plans are on hold.. Undecided as of now.
I did just purchase a 3.636 rear end though.
After leaving the gym last night I stopped by to catch a beer with a buddy of mine.. Look what was also out for a drink...
