Muckman brings up a good point. I wasnt aware of this, so if that holds true seems like that would be a better choice.

I would go the 3076R route, and yes that is a biased opinion but take it from me, that is the ultimate street turbo imo.

Pfi just recently moved into a new shop. It's outstanding and 30 minutes closer to me . I dont mind the slight hijack, gives me a chance to plug them

That's awesome, good for brent, glad he is doing well......When is that monster car he built gonna start laying the smack down in outlaw class?

I'm running what's been called the GT29 (GT2871)

4" inlet and 2" outlet on the comp housing

Turbine
- Wheel: 53.85mm w/ 76 trim
- Housing: .86
Compressor
- Wheel: 71mm w/ 56 trim
- Housing: .60 A/R

I can't recall the full information, but I'm pretty sure we had the turbine clipped for more flow as the 76 trim is a bit restrictive on the 2871.

At WG spring BUT with a fuel reg issue, had to fixed and it made 320hp and 240ft/lb.
The turbo should be good for 400+
Makes full boost early and has a little creep.

400bhp, perhaps, but not so much to the front wheels. On most forums, the measurement that most go for is to the front wheels and not BHP or Flywheel HP. So one must be careful of such possible misconceptions.

EddieCRX

Not questioning your superior knowledge, I'm running what is essentially a hybrid version of the OP turbo (GT28RS, his seems to make 353bhp at the wheels, my turbo being built to make slightly more power should be capable of making close to the numbers he wants. The graphs I posted was to show how it spools, regardless of numbers, the OP wanted reasonable spool and more top end, my post was just to show he may have the possibility to modify the platform he's running.
If it was me, I would move away from BB turbo onto a Precision, they seem to produce similar characteristics to the GT range without the cost associated with new cores.

TheShodan

No worries. But you would be doing a disservice switching away to the Precision line right now. the core exchange program is needed only if there's damage.

EddieCRX

Oh don’t get me wrong, I love the GT turbo, it’s the perfect fit for my current goals and I really enjoy the power delivery both on the road and track, that said, I was warned that the cartridge will need replacing at some stage and to be prepared for a large bill. The Garrett UK dealer that sold the turbo (Turbo Techniques) no longer deal with the GT range due to high costs of the cartridges, I will be looking up a dealer in the US as and when mine decides to give up. I follow your threads/post and see the latest range of journal bearing turbo’s offer some real advantages, that said, you’re right that I shouldn’t be so keen to move away from the GT as I really do enjoy the drive, not into change for the sake of change but a replacement cartridge here in the UK will cost as much as a replacement Precision unit.

I really appreciate everyones time and input. I have been super busy the last few weeks so haven't had much of a chance to deal with this other then thinking about everyones input.

That said we have a winner. A GTX3071r

Let's talk a/r.

What peak power and spool time do you think I would get .63 vs .82?

TheShodan

iTrader: (14)

They are both using the same 60mm exhaust wheel as the GT3076R. I would stick with the .63A/R for good responsiveness and try to retain the same good broad powerband as you have than worrying about some silly peak HP number attempt while trying to use the .82A/R

"spool time" is completely irrelevant. this is about a good usable powerband with the size engine and Volumetric efficiency you have.

TKERacer619

Sweet, thanks for the response!

This is what I figured but I just don't know enough about these specifics to do it on my own. I appreciate the help. With all the turbos I have fried I should know this stuff by now but tbh I always just trusted others picks without question. Not again!

Will let you guys know how tuning goes

TKERacer619

Turbo should be here soon. Thanks for the advice!!

Ignition parts are in. Thanks for the advice!!

Need to order the hot side but will order that in 2 days.

I am trying to decide on fuel and injectors to run. Currently I'm on e-85. I was just told about a place about 8 miles from my house that has 100oct and e85 on tap. E85 seems to be becoming harder and harder to get for me so it might not be more convenient then 100oct. I have on several occasions had to traveled to 4 stations before getting e85 as the supply seems inconsistent and the one place that was consistent closed.

Right now I am using an in tank Walbro 255 and have rc750 injectors. I know I need to do something about both but what?? Dual 255s and ID1000cc injectors? Is there something else I should be looking at? I hear good things about ID. Is it hype or are they legit? RC was the jam back in the day. Would 1000cc cover what I am looking to make with some wiggle room or should I go higher?

Standard fuel in Denver is 91 so I'm pretty much stuck with e85 or 100oct.

I appreciate any input.

my review of the GTX3071R that we had around.

TKERacer619

Thanks for the video

After reading some more I think I am going to go with the ID 1000cc injectors. Its pretty clear to me that they are going to be enough.

What about the in tank pump? Its a walbro 255. If I choose e85 I am going to be close to its limits I have a feeling. If I choose 100oct I am probably fine with the walbro. I am thinking the Aeromotive stealth 340lph pump just to be safe. I have a buyer lined up for my injectors and pump already so no big deal to upgrade.

Sound like a plan? Anything hidden I should know about?

Did you get this car running? How do you like GTX3071R?

TKERacer619

Not yet. Turbo still hasn't landed in my hands and the shop isn't calling me back

Its the only thing I have left to do. Well other then find the keys to the car... I hid them like usual when I went out of town and well... I did a good job hiding them.

You may want to read the previous page of what he decided.

OneBadTurboCRV

I don't know if you got the fuel pump yet, but the Aeromotive pump is only good for E85 if you change the filter around every 10 hours or something... or so I hear. The newer Walbro E85 pump is your best bet...

TKERacer619

Nope haven't got the pump. Already had a Walbro 255 so I just left it at that for now. Will probably go with the 450 next time around. Thanks for the heads up.

Turbo is on the car, its running. I was able to get the tune close enough for it to run. Coil and Summit box are on. Today I am going to tackle the ignitor bypass and flush fluids.

During my final assembly I decided to pull the oil pan. This was a good idea. If I didn't I doubt my engine would have lasted a dyno session. Lots of pieces of turbo bearings and some other questionable material were in the pan and pickup.

Engine sounds fine so I am going to take it to the tuner tomorrow. I have an AVCR boost controller that has been installed but unplugged for a long while. I think I am going to switch back to that from the AEM EMS for boost because it does boost by gear. Will probably try to keep it around 350hp and go back for more power once the AVCR is setup and dialed in. I'm sure I will get better results with boost by gear compared to boost by Wheel spin speed.

Everything with the instal has gone smooth except for whatever reason my recirculated dump tube doesn't want to fit. I have always had to use a 38mm flange as a spacer between the wastegate and dump tube, it was simply the difference between two versions of our wastegates when the manifold was made. It turns out this mistake was a blessing in disguise as the new turbine housing is close but not exact. The difference in housings moved it just enough that the dump tube would not fit. I took the spacer into work on Sunday and did a little machining. It needed to be a slight wedge shape. Having access to a machine shop 24/7 can be handy

from Aeromotive's FAQ's

WARNING: If you plan to run E85 fuel you must be prepared to install proper filtration, and maintain it as frequently as every 10 run-hours. If not, Aeromotive does NOT recommend you the use of E85 with the 340 Stealth Fuel Pump. Aeromotive’s new product warranty assures the purchaser their 340 Stealth Pump will be free from defects in material and workmanship for one year from the date of purchase. Fuel pump failure caused by clogged/blocked fuel filters is not the result of any defect in the pump itself, and is not covered under this warranty.

I shortened the drain line 1/8". If its done right it should stay put without holding it.


This is a oil feed line I used to hold the oil restrictor and keep flexible lines away from the manifold. It is made from a bendable brake line.
