Well, Turbonetics told me to fuk myself

Many of you read my previous thread about turbo failure.

Well, turbo netics stood by their product 1 time, not the 2nd. So fuk them.

Anyway, looking at a gt2871r 472560-15

I want my dyno to look like it does now, better spool would be nice, but definitely want the same TQ/hp.

Thing is, I need a turbo that wont shit itself from shaft speed.

Running up to 20psi is no issue..

Opinions please..

Thanks for your help

PS- Turbonetics suck ass..

Try these guys

their design is supposed to support higher shaft speeds and be more durable-although I've never used their turbos

I know that Turbonetics supported the South African Apartheid and kick puppies.

Borgwarner is where it's at...So i've heard at least.

not sure if you are interested but i may have a BW s200 should flow around 55lbs make you enough power. read upon it rather good turbos for the money compared to gt30xxr

I have that exact turbo, search my username for dyno results. 250tq at 4800rpm, 280whp at 6400rpm.

he's going to bitch and moan about not getting target boost at idle.

buy new from ATP. several d00dz here can get discounts. spend the money.

I have to throw it in here. 3071. Owner says he gets to target boost 500 rpm sooner at sea level than he did in Colorado. The smaller numbers are from a bitch ass 2560.

Note this is on a 2.0 and is corrected. Shift the power a little to the left and knock off 15-20% and I bet that's how your car would perform. Pretty much even to, maybe a pinch more, than where you were.

I was looking at your thread. That was at 14psi correct?
I want to see 300tq on a mustang. think 20psi will do that..

Hustler knows me all too well at this point. My issue isnt reaching power goals. Thats easy. Its when there is power.
My last dyno plot was fine. I just need a turbo to hold up and do the same.

I can get the gt2871r delivered for 1k even. Is that good??

What if the gt2871r came with a .48 a/r housing? Can that even happen??

What off the shelf turbo do you folks suggest?

I will be selling the engine, engine managment, and entire turbo set up in december

Way to look at the data, then say something really fucking stupid.

No fighting guys.

I just fear the 3071 because I only have a 1.8l

If it was a 2.0 or a 2.4 I would be all over the idea..

I am being told I can get a gt2871r with a .48 a/r on the hot side. That sounds good..

I thought you were running a 1.9.

I've been looking at T2 trims, but everything I see the 3071 gives up NOTHING to the 2871 and makes more power everywhere.

Keep in mind that chart is 2560 vs 3071. Note the very minimal difference in low end torque and then look what happens up top.

I'd love to hear you explain this. He wants low 300whp, and his emphasis is on spool, so you recommended a 30R - and I'm the stupid one?

If by "good" you mean like "250whp MAX with horrible spool". You want a .64 at minimum. I'd actually give some serious thought to a .86 2860RS - a little more response and low-end than the 2871, and probably a better match if your endgame goal is 300wtq on a Mustang.

Makes sense Sav

This sucks. I just wish that turbo would hold up..

so you have this 2871
TurboByGarrett.com - Catalog

and this one
TurboByGarrett.com - Catalog

what about that smaller trim compressor wheel?? with a .64

Would that smaller trim help much?? compressor map looks like its right there for me. But will it spool quicker with a smaller inducer?

I doubt he'll like that:

He doesn't have a super-manifold either, so it will spin up later. He needs a custom job and he'll be happy. I say tiny AR on both housings, crazy-aggressive wheels, big EWG. He can make 300whp at 16-18psi though.

So big hustler, what do you think about that 2nd link to the smaller 2871r??

Compressor map looks decent.

Lots of interesting reading.

(IIRC the 2860RS and 2871R have the same NS-111 9 blade turbine wheel, and my guess is that the 2871R is turning a bigger compressor wheel..)

The 3071 does on paper have a less restrictive hotside (it certainly looks bigger) and therefore better thermal management and possibly more timing advance potential, not to mention more airflow potential for future mods. I could not get any more timing with the 2860RS at 12 psi than I could on the same car with a 2560R. On other cars with the 3071 however I've been able to consistently get more advance at that level of boost.

When weiging the variables therefore for 300-400 rwhp I'd still go with the 3071. It makes for a very fast car when done right.

Which 3071R do you guys normally use? T25 or T3 turbine, which A/R, etc?

We use the T25 flanged 3071 so that it bolts into our FMII kits. .64AR turbine.

I've driven many of the turbos on "the list" and I still think this one is the best option for a ~300-~450 rwhp Miata.

Also, if you remember Andy Floyd, he ran a 3271 on a 1.9, and hit 300whp and 270wtq on a mustang. Target boost of 16 psi was achieved at 4700 rpm.
