My New Turbo GT3076R - WG

[eazye2000]

GTFO of KA-T....

I have a FUEL PRESSURE REGULATOR. Nowhere near an FMU. My FPR raises pressure per psi of boost on a 1:1 ratio. A FUEL MANAGEMENT UNIT is NOT anywhere near an FPR. It does not regulate pressure like an FPR does. Try using an FMU as your only 'fuel management unit', tar-tar.*B|TCH *

And second, if you know so much about turbo cars, how much power can 740cc injectors support on a 4-cyl motor? 'Roughly' how much PSI does it take? And did you miss the part where I SAID I had 740cc injectors, and I KNEW what my AFR's were when all this was going on? Let me refresh:

No way I'm maxing out my 740's.. And AFR's are great up until she breaks up. Low 11's actually..

how do you just assume that its spark blow out when you cant see it.

Did you miss that part too? And the part where everyone agreed? I'm running a ridiculous gap. It's an easy fix.

I'm not touching the rest of your ill-informed comments. You just dug your own hole of ignorance.

I state again, GTFO of KA-T.

obviously the ka is the only motor uve ever turbod so let me brake it down for u s l o w l y... an fmu is a fuel management unit, an adjustable fuel pressure regulator that also raises fuel pressure according to boost on a ratio. example: on a 12:1 ratio fuel pressure is increaced by 12psi for every 1 psi of boost. since it is a larger turbo it pumps a larger volume of air (air flow rate is different then psi pressure) depending on the ingectors, the tune, and fuel pressure hes running it could be runing lean and cause a missfire. how do you just assume that its spark blow out when you cant see it.

you cant break things down if you cant spell words correct LOL!

increaced? did you mean > I N C R E A S E D ?

ingectors? did you mean > I N J E C T O R S ?

oh yea and UH! uve? WTF! did you mean Y O U' V E ?

WHOA! i was kinda suprise you spell OBVIOUSLY correct because i thought it was gonna BEEEEE WONG LMFAO! oops was that wrong also lol!

little kid you so smart we would like to meet you at a nico meet or just any kind of meet so you can share you skills to us ALL! lol!

[audtatious]

You're an idiot...you don't use an FMU with larger injectors...

I've said it before, and I'll say it again...

KA-T <3s WD.

Also, that is a sick turbo.

I need help, my bov goes on my exhaust right? After or before the cat?

[eazye2000]

Make sure you put it on, AFTER the cat. You want to blow off that extra exhaust back into your intake. After the car for sure since it will filter out all the air, and put Oxygen back into your car.

Are you gonna get dyno'd soon eazy?

And you're running this turbo on your gt2860 tune?

[eazye2000]

I'm hoping to get at least 3 guys together to hit the dyno. They're expensive up here if you don't get a group discount. New England SUCKS teh fat dizzle.

And yes, I'm running it on the old tune. I'm going to change my plugs, and gap them smaller tonight. Gonna hit the highway and turn up the boost. See if that helps.Jason (eMance) tunes across the board, so I shouldn't have any problems with the tune. Maybe a rich/lean spot here and there from the lag/no lag of the turbo and tunes. I dunno.

[eazye2000]

Sorry for the nubbish'ness. But I have a question....

What is the flow capacity of this turbo? Not factoring the T2 turbine...Like, how much PSI for how much HP... I'm retarded when it comes to reading compressor maps....This is the closest I could find to my compressor. Mine is a .50ar though. Same diameter and trim I think.



ALSO:I gapped my plugs at .030, and whammo! I can run 25psi with no hiccups. I don't know if it's the plug gap, or the tank of 100-110 octane I'm running.But so far, so good. My new tune from Jason at eMance will be here this week I hope. Has a 2-step built into it. I'm stoked!

[sunnys14]

I guess I was right about the plug gap. I cant believe you were running above 22psi and still running .040 gap.

How does the turbo feel for you?

[spooled240]

nice turbo! That's weird, a flash spool on a t2 flanged turbo lol It looked like an easy install and HP upgrade, GL with that :bighthumb

[eazye2000]

I guess I was right about the plug gap. I cant believe you were running above 22psi and still running .040 gap.

Yeah, .040" gap was pretty big. Maybe it was the blaster coil paired with the Nology Capacitor plug wires I have. I dunno. I thought I could get away with it, guess not! haha

Turbo feels good. I'm kinda scared having a lot more power. I don't know what to do with myself..

[WDRacing]

Until I see a dyno I don't even believe you own that turbo

[eazye2000]

Dyno's are expensive here! I have two other guys that are supposed to be getting with me about going one day. Get a discount or something. The hobby shop on base has one, but it's for inspections, or emissions or something.. bummer..

[WDRacing]

Can you atleast unhook the wastegate and make some 1320 passes?

Did you have a dyno of the T28, or can you make a good comparison of how much more power this turbo makes?

When does it hit 10psi, 20psi?

[eazye2000]

Sorry I haven't been on lately. Been working on some stuff around the house, and helping friends. But someone asked, so I'll update a little.------------No track times as far as the quarter goes. But I took her up to the local oval for drift practice, and HOLY s***!!!But I don't know how much power she makes. I did the 248 exhaust cam swap to the intake side. But I used the write-up on here to re-drill the cam gear to make the cam dead nuts, instead of the 2 degree's its out if you just throw it in there. It's actually about .7 degree's advanced really.But up top, this mother pulls soooo hard! As soon as Jason at eMance fixes my tune, it's game on. I can only run about 18psi and feel safe with the Disco Tune he sent me before. I can click it up to about 26psi with 110octane, or c-16.

I get like 8psi at 3k I think..? I'll double check today. It's not at responsive as I thought it would be. Once you get over 3k though, the boost comes on pretty hard. Almost like 'flash' spool, which is odd considering it's a T2 turbine.?Honestly, I've been thinking about dropping down to a GT2871R with a .8x ar turbine. This turbo is too much for a street car. She's not a race car, and I don't think I want to try to make 500whp out of a T2....The disco I had spooled 10psi at 2200rpm. I don't know if I got used to that, or what.

So that's it so far. I need to get a few more things, and I will be making a custom intake manifold for it. But I will update as things progress. Just remind me to update. I'm getting old and forgetful...

[nissanfanatic]

The GT3076R will surge at anything before 3300RPM at 18psi on the KA. The GT2871R will surge at anything before 2900RPM at 18psi. That is as early as you can make full boost and operate the turbocharger safely. The GT3071R will give you the same surge RPM, but allow you more room for power. They both sit on the 15lb/min point at 18psi, but the GT3071R goes to about 47lb/min whereas the GT2871R goes to about 44lb/min. I would go with the GT3071R over the GT2871R. It gives you much more room, and the same low flow characteristics.

[sunnys14]

Even if its a T2 flange, this turbo is making huge power. A .86AR T2 turbine housing is equivelent in size to a .63AR T3 turbine.

[eazye2000]

Dunno what's up with my sig, hmm..

Anyways, found out tonight, that I melted the solid copper gasket between my manifold, and turbo. How the f*** does that happen?

Regardless, I'm upset. That thing sucks to change. No room under the mani with that monster in the way. lol I may re-do my coolant lines too. I don't know. I'm almost fed up with this thing.And if the 3071 is the way to go, then by all means.... I'll shoot for it. But swapping out GT series ball bearing turbos all the time gets expensive.

[WDRacing]

Real turbo's don't spool at 2000 brah...lol. Keep the one you have and up the boost...you'll be happy.

Sigs now only apear once per thread. Saves on space and load times

[neverlift]

so I have a real turbo now wd?

anywho, go with an oem gasket, trust that is where its at....s/s ftw

[eazye2000]

So the multilayer Stainless gasket, or the stainless one, with the rolled lip into it?I've seen a few different ones, so I wanna get the right one this time.FFS I hate this car when it takes a crap on me.

[nissanfanatic]

Even if its a T2 flange, this turbo is making huge power. A .86AR T2 turbine housing is equivelent in size to a .63AR T3 turbine.

No, its not. Calculate the area of the inlet port on each and tell me they are the same size.

Same with T3 to T4.

GT3076R's don't make huge power.

...

You should be able to sell this turbo and make up for your loss on the new purchase. If I was still using a T3 flange, I would probably buy it off of you. The 3076R is such a great street/track turbo. Track as in road course.

[sunnys14]

The overall housing size for the .86AR T2 and .63AR T3 is pretty much the same, not counting the flange size.

GT3076R's will make alot of power, enough for an average KA-T owner. Not everyone wants a T04R with a 2k powerband.

Do the math.

A T2 flange is the equivalent of a pipe 1.92" in diameter.A T3 flange is the equivalent of a pipe 2.33" in diameter.

If that was an exhaust, which one would you choose for your car?

A/R ratio can be anything. The area could be (0.2"^2) as long as the radius from the center of the impeller to the center of the exhaust path measures .24, the AR is .83. The impeller size can give you some idea of what is going on there. AR is used mainly to ensure that exhaust volume is not changing direction too fast. Larger exhaust volumes will require a larger radius as to not be very restrictive. In general, a larger inlet flange will dictate a larger area exhaust path.

And don't even start talking **** about my setup. I can drag up plenty of your retarded, blown engine/headgasket threads. You didn't even get the insult right, I make full boost at 4200RPM.

[eazye2000]

I understand what you guys are saying. The overall 'AR' of the two are similar. It's the FLANGE that is bottlenecking everything.It even says on Garretts website somewhere, that the .63 T3 housing, flows almost the same at the .86 T2. BUT, like Corey said, the flanges are what keeps everything from flowing good.

I just got an e-mail back from ATP. They can machine a T3 (T31) housing for me to accept the 56.5mm wheel of the 'T2' 3076R. It will be a T3 .82 A/R housing. Bad thing, is that it's gonna be 275 bucks... I really want to keep this turbo. I really like it, and I don't think I need anything bigger. This is a street/weekend car. It rarely see's drift, or autocross stuff, but sometimes.

Anyone, please give input. I like to hear everyones opinions. And even Corey's "super NASA quasi-equation" crap... (I wouldn't give you s*** if you explained it so dumb people like me understood it!)

[nissanfanatic]

In his defense, the maps show the .86ar T2 housing flowing about the same as the .63ar T3 housing.

Those charts are pretty weird though, as I can see random typo's in efficiency, and the number do not correspond. So, no idea there. I still do not think I would use a turbine with a smaller inlet to flow as much as a turbine with a larger inlet. Common sense prevails there. The outlet size would also be a factor. But Garrett doesn't seem to list the exducer size, only wheel diameter and trim.

[sunnys14]

Boosh. Anything else?

eazy, can you hear your turbo spool? I can barely hear mine and i'm only at 12psi. It's even more quiet than my gti-r and s14 turbos that i've run. I thought it was my wastegate flap being stuck open but I tightened it and same results.

sunny, you have your gt30 installed? hows the power and getting any dyno chart so far?
