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.

So you give him peak power numbers from a car that flows a TON more air and is much more efficient on boost. And shares almost none of the characteristics of a turbo BP. Not a graph to show spool or curve, not a compressor map, and not a log.
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.

Seroiusly, is there really any competition here? I'm interested to hear a counter if anyone has one.

You're retarded and have no idea how cars work.

Holset>EFR>GTX


OP, do the 2871 upgrade, make 400whp, floss.

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.......

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

ATP has the "upgrade" on their site for just under 1100 bucks. And you are correct, it's ball bearing, water cooled and you will not have to change any of your hotside parts or your intake parts. Straight CHRA swap.

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.

like OMG U sure showed me

OP wants ease of install, money wise it's the GTX . Borg Warner > Garrett. Plain and simple. It's not even a contest anymore.

My only problem is - I'm making more power than every one of the GT2871 guys on this site. (From what I've found)

Nope. Andrew is making [email protected] 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.

Unrelated - But I setup anti-lag. Don't really need it but Adaptronic did it pretty well.

Setups in order of best to worst for your goal IMO:

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.

Good to know - I'd like to sit comfortably at 340-350HP without working a turbo to death and creating a ---- ton of heat while doing it. It'd be much easier on my setup to achieve that power with a turbo that is efficient in that power output range right?

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.

What I SHOULD do is just dial back my boost to 15 lbs, get some race compounds and get this car off the street. It's going to get me into trouble.

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...
