My New Turbo GT3076R - WG

[eazye2000]

Some of you may know that I was running the GT2860RS for a while. Ran her with very good results I might add. Had the .86ar exhaust housing on it running the stock internal wastegate. Ran 12's in the quarter with no issues on my EMance tune that I received from Jason.But sold that because I wanted a little bit more out of my motor since I built it from the bottom up to withstand some abuse, and to make some good power.

On to the new toy! It's a GT3076R-WG something or other. It's still a T2 turbine, but it has been machined out for the bigger exhaust wheel. Keeps the internal wastegate, too. It's really pretty neat.

And onto the pictures! I'll post a few, but here's a slideshow for you guys.http://s85.photobucket.com/alb...eshow









Let me know what you think!

Good times ahead...

You need to unhook the wastegate on this fvcker to...or you don't have a hair

Awesome man, i remember you saying that you were upgrading to this bastard child of the t2 flange, thought it was a great idea then and i still do. Glad to see you finally got it, cant wait to hear some results. Bet the spool ups still great. How much HP can that turbo flow efficiently?

Its pretty wild looking at that 5 bolt housing, they really had to take off a considerable amount of metal to fit that wheel. Look at how much metal is in between the wheel and the wastegate flap, pretty crazy stuff.

Lol WD brings up a hilarious point, bet you wont be doing that with this bad boy. Cmonnn you know you want to!

[WDRacing]

Garret says she'll flow enough for 525HP...The T2 flange will be the limiting factor for this turbo. Although I'm pretty sure he'll be able to hit the 400's pretty easily. If you need more flow, you may need to forgo the internal gate and install a 60mm external.

I forecast 1 full bar of boost by 3100 rpm.

how much did this cost you?

[WDRacing]

He sold his left testicle on the black market...

[eazye2000]

how much did this cost you?

It ran 1120 give or take some change, shipped to my door. They threw in a 3"-4" silicone coupler since I have 3" intake piping and that beast is a monster.. lol

I took the compressor off tonight, and I'm gonna take her apart slowly. Gonna smooth out some casting marks on her, and maybe open up that wastegate port a bit. Not sure yet. It's intimidating to even look at.. lol The compressor totally hides the turbine if you look at it head on.

does this t2 get your approval? lol

eazy- where did you get it from?

[240sxvaj]

Will this turbo be a bolt on for your current (bottom mount)t28 set-up? i'm thinking of buying a gt2871r and its going to cost me about the same price as that gt30. Get some results on the dyno and track and let me know if it's as responsive as the t28. after my engine build i'm upgrading the turbo, but dont know what i should go with.

[ghx407]

Very nice!!!

[sunnys14]

I have the same turbo! Check out my rebuild thread.

[eazye2000]

Ok, so I got it installed, and everything works great. Had to make a wastegate bracket, but whoopie doo. Took it for a drive, and the gate holds her at 8-9psi. I bleed off the gate, and it only goes to about 16psi. Way less than the Disco. So I don't know what's up. Gonna actually buy a boost controller I think. lol

Anywho, here are some pics for you guys. Just a few. And I took some of the clearance for Brian since I've been promising them for about a year now. lol

[WDRacing]

I'm thinking the remote mount external gate would definitly work man. So if you run into backpressure problems I'd rock a 60MM and route that dude down by your transmission

[240sxvaj]

Nice! Do you have enough room to put a inlet pipe for the filter? Got to get it done and get us dyno# plus track time. very anxious to see the results. keep us updated and post a video after you get it done.

[arsvtcobra]

Nice! I bet thats going to be fun. What hp are you expecting out of it if you dont mind me asking?

[eazye2000]

Intake piping was a pain in the rear. I'm a little unsure of it right now. I'm gonna have to change it I'm afraid. I need to order some stuff. I'll snap some pics for you guys.

As far as how much power am I expecting? I have no idea. This turbo has a bit of the 'flash spool' after about 3k. My old turbo made 10psi at 2200rpm's. So it was really linear with the power. No flash spool to speak of. But this one hits pretty hard. I've not driven her that much to take my eyes off the road and look at the gauges. But I'll get you guys some numbers as soon as I can.

[sunnys14]

What size intake pipe are you running?

3" or 4"?

Im running a 4" pipe with a 90 degree bend right off the compressor housing so it clears the power steering quite a bit.

You should get a picture of your set-up.

[BACARDI_DWB]

how thick is your wga mounting bracket. it does not look that thick/braced, it could be flexing under boost and not allowing you to hold more boost. try building a beefier bracket or strengthening that one up.

especially since you pulled the vac line off the wga and you still only boosted 16psi. it should of held the flapper shut till about 30+psi. if its pushing only 16psi and the vac line is off. that is telling me that your bracket is flexing allowing your exhaust flapper to open.

it could be something else but my suggestion is the wga bracket

[DrifterProdigy85]

What do you mean by "bleed off the wastegate"? If your removing the WG Line and only hitting 16psi then the flapper isnt holding shut. My 2871R will hit around 26psi without the WG Line. Maybe try tightening the Actuator Arm. If you dont have enough tention on the WG then you will have exhaust bypassing which will cause boost issues. Ive always been under the impression those adjustable actuators should be around 10psi to start and can be tightened up to 14psi. At least thats how my ATP Actuator is on my 2871R.

[240sxvaj]

How's the car running? get it dyno or something i want some numbers, so that i can start deciding on my turbo choice. still not sure if i want a t2871r or gt3076r since they cost about the same. my motor is almost done and after i use my t25 to breakin my motor i want something bigger.

I'm running a 3" intake pipe. I got a 3-4" reducer so I could hook up my piping, but it's not clearing very well. I bought a 45*degree, 4" to 3" silicone coupler. I've not put it on yet, due to lazyness... lol

I also have a SSQV BOV coming this next week. So Intake, hot pipe, and cold pipe are all getting redone while I finagle stuff. Debating on keeping recirc, or open BOV.

how thick is your wga mounting bracket.....

It's pretty thick. It's actually, like 3/16" mild stock. It's welded to the compressor housing bracket-holder thingy. Like a big washer that spans two bolts I guess...?I found out why I wasn't boosting any higher with the line bled off all the way. The line wasn't big enough to bleed out enough of the air. I put a Manual Boost Controller on it, and she does about 22psi before she breaks up. Either the tune(from the 2860RS) needs re-done, or I'm blowing out spark. No way I'm maxing out my 740's.. And AFR's are great up until she breaks up. Low 11's actually.And yes, the arm on the wastegate was a little too tight. I fixed that to where the arm was neutral with the flapper, then gave it one turn tighter on the screw.

Um, if you are breaking it in with a T25 and a bottom mount mani like mine, I would say go with the 2871R. I should have done that in the first place, and I wouldn't have been so eager to get rid of my 2860RS. I think I went overboard with my turbo....It's a T2/T4, and it's just mind boggling. The turbine housing was machined out quite a bit for the larger exhaust wheel. Not a lot to seal to the elbow.

But like I said, she's breaking up a little over 22psi. I really think it's the spark getting blown out. I thought I was a 'baller' and gapped my plugs at like .040 or .042.. lol I have a Blaster coil, and Nology wires. I thought I was immune to spark blow-out. haha

No dyno numbers yet. But at 15psi, this thing pulls harder than the Disco did.

[eazye2000]

Also, I cleaned up the Brake Master heat shielding. I put the original one I built back on there. Then covered it with thermal reflective tape. Along with the brake booster. I really need to build something a little more 'complete'. I've thought about tearing the engine out, and re-doing ALOT of things..

When I installed this turbo, I forgot to pull the A/C line out of the way. So my elbow/downpipe burnt through it. Fixed that with a trip to the junk yard. Picked up a few other things too. I will post up on that venture later!

[sunnys14]

You have your plugs gapped at .040 and tried to run 22psi?? You're blowing out spark for damn sure, drop the gap to .030 and you should be good to go.

[racersonly2004]

hmm if closing the gap i litlle dosnt help you might have a fuel concern we had a car come in at work not to long ago that had the same prob we recomended ading an fmu that increces the fuel pressure acording to boost pressure on a 12:1 racio. since it is a larger turbo its pumping alot more volume of air so u could need more fuel. i wasnt reading to much into your setup but if you run that much boost, and depending on the compression ratio it might be octane to low. if the turbo is watercooled it should help with pinging. but it can be hard to diagnose the problem without the vehicle in ones pressence.

Seriously dude...can you just post in Gen Chat or something? You have less then no idea what you're talking about. Until you can post something that actually makes sense, DON'T POST IN KAT...DON'T EVEN REPLY TO THIS...JUST STOP POSTING.

If I want to post nonsense, or something dumb, I go about it this way:

[racersonly2004]

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 are an abrasive retard.

Your going to get banned if you keep acting/posting like you do.

We dont need your misinformation, we dont need your attitude, and we dont need to strain our brains reading/trying to understand your horribly composed posts.

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