oil/water lines
intake pipe
connectors/clamps for the intake pipe and lower pipe

 

Shouldn't be paying anymore than $1200 for an authentic GT35r, with a ported shroud cover and your choice of 4 or 5bolt (PTE) exhaust housings.

 

you forgot a bigger intercooler to support the turbo
new licp and couplers and t bolt clamps
oil lines and water lines
720 or 1000cc injectors
some kind if intake for the turbo

 

The 02 housing we have is the flat flange just like we use on our normal kits.

 

I was on Christmas break so sorry for the delay. Manifold received and it looks pretty good. I searched long and hard for some oddball combination of compressor/turbine wheels from common and uncommonly available turbocharges to see if I could get something that was better matched and more efficient. However, after some digging I decided on the GT3076R. The GT32 turbine flowed no more than the GT30 turbine wheel and it is larger. There were a few maps from the GT37R's compressor that were slightly more efficient at a 2.5PR, but only marginal. Anyway, I had one shipped to me and opted to use the .82a/r t31 style turbine housing. This has the 2.5"outlet so I will probably use a 2.5" 90 deg bend off the turbo and then a reducer to go to 3". I would have had to cut down the outlet on the GT housing to make it work so I spared myself the headache as I was unsure whether there was a benefit. I am going to have turbohoses.com make me a custom inlet hose much like the Samco, but made to match the 4" inlet of the anti surge housing. I may or may not decide to try and make it compatible with the stock downpipe and donut gasket. Perhaps just a bellow and v-band clamps.

 

The GT3076 is a turd of a turbo, in my opinion. To each their own though.

 

I run both those parts, from now on I'll refer to it as the ****box....haha

Buschur's "deluxe" design eliminates several bends and 20" of piping. It's great for a stock or small upgraded turbo, which is what it is intended for. They have a race FMIC for high-flow applications.

And if you have ever looked inside a typical bar & plate IC core, you would see that the air is practically smacking into a wall as soon as it gets inside anyway. Aside from the ARC, every bar & plate IC core I have seen is less than 50% open to airflow at the hot side inlet into the passages. (ARC tapers theirs which is a big part of the extra cost)

 

It really isn't eliminating piping as it just builds it into the IC. Interesting design.

 

Actually dave is right, Ive done some research myself on that 3076r. Spools like crap from what I hear. 3071r spools 1000hp sooner and only loses a touch on top end. Turbo is still good for 30psi with just a few lbs of taper way up top. Might want to take that into consideration. This is from Garrett:

This turbo is the newest addition to the Garrett Ball Bearing Line up. It fills in the requirements for small displacement 4 cyl. engines and has a excellent response characteristics. It spools up 1,000 RPM sooner than the older GT30R. The Dual Ball Bearing GT3071R Turbo comes assembled with T3 style turbine housing with T3 inlet flange. Turbine housing style available in Standard GT or with T3/T4 Ford Style 5 bolt turbine housing. Compressor housing is T04E frame size with 2.00 outlet. Compressor inlet is available with 2.75 or 4.00 inlet.

Turbine
-Wheel: 60mm w/ 84 trim
-Housing: .63 ar, .82 ar, 1.06 ar

Compressor
-Wheel: 71mm w/ 56 trim
-Housing: .50 ar

 

3071 does not spool up 1000hp sooner than the 3076 nor does it spool up 1000rpm's sooner that is absolute manure. If a 3071 spools up 1k RPM sooner thats saying that it spools quicker than the stock turbo which I find impossible to believe.

Show me a 3071 that has made decent power, as from what I have seen the 3076's seem to make a good bit more power and tq.....

Wow I can't belive I didn't see this earlier. I have been running this setup for a while now (Since August '06).

I have below:

REV Hard Cast Manifold
Garrett GT35r w/ 4 bolt 2.5 discharge
SB SS oil feed / return
Custom SS water lines
Custom 2.5" to 3" downpipe
PTE 880cc injectors
AP Fuel Rail

Thats it and my car did this tuning FUEL ONLY (stock timing) with the factory ECU using ECUFlash:



I can get more pictures up when I get home on my laptop. I have pictures of the build and all. Look below for all the mods...

As for the manifold, for the price (I think i paid $275 to my door) I was impressed. The inside however needs work. It needs cleaned up from the cast. It looks like they cast it and just left it alone and no one went inside the manifold and cleaned it up to help it flow better. I cleaned it up as best I could and slapped it on there to see what it would do. As you can see not bad at all!

To answer some of the questions: You have to use the 4 bolt 2.5" .63 hotside if you decide to run a GT35r. I tried the bigger 3" but I didn't have enough room for my downpipe to clear my AC/PS pump. I made a custom 2.5" to 3" downpipe and it works great! The turbo sits far enough right but the GT35r is so big I had to replace my fan to a slim fan.

Everything else fits perfect! I am really happy with it for the money and I made a GT35r turbo for my car for under $2,000!!!! I was very happy with this!

Let me know if you guys have any other questions...

Show me where it says that? I'm flipping through there product page with all there turbo's listed and under the two 3071 turbo choices and single 3076 choice they mention nothing along the lines of anything you . Also the ones on there webiste are all internally wastegated I believe, which uses a different housing and I'm sure doesnt flow as much as any of the externally gated versions.

Instead of showing me what Garrett says show me a good performing 3071, on an evo, and show me its stock spool because I am going to say it doesnt happen. There is no way you will make full boost 1000 rpms quicker with a 3071 vs a 3076, unless your using like a 1 liter bike engine and revving to 15k...... then it might be a 1000 rpm difference.

I also think your incorrect, the older GT30R is a completely different unit altogether, the current 3071 and 3076 share all the same technology, maybe you shouldnt be playing somewhere you don't know the rules.

Here is an example of a good performing 3071. I know DynoJets and DynoDynamics read differently, but I make 50 whp more on pump and 90 on race gas, thats a big difference.

As for the 3076, it is a turd. I have dyno'd them, used our kits with them and other kits have come through. The turbo is a waste of effort and time. There are SO many better choices that choosing that turbo is just not good research. It's not even my opinion, it is absolute fact.

As for the 3071, it is a small turbo. I have an EVO out there right now with our GT3071 kit on it and it actually works really well...........I just pulled up a log of the car we used it on. 2 liter engine. Makes 20 psi at 3800 rpm. A GT3076 for reference won't make 20 psi until about 4400-4500 rpm. So it is not 1,000 rpm but is a solid 600-700 rpm sooner. At 22 psi on pump gas this car made 360 whp/321 torque. It is a road racing EVO and was set up very conservative.

Comparing that to the new EVO green, I would hands down suggest an EVO green over the GT3071 turbo. If I was choosing a turbo for my own car and had to choose between a 3071 and a 3076, I'd probably choose the 3071, if those were my only two choices.

Being as we all have many more choices I would choose neither of them and either use the 3065 or the GT35R.

 

Interesting DB, however calling any turbo or engine component or what not a turd is an opinion. You do not like them, this is obvious, but just because you do not like them doesn't mean other people don't find what they offer attractive, or like using them. My 3076 makes full boost before 3800 RPM's now with the 2.3 however it was closer to about 4200 rpm on the street, maybe the differences in manifold design can acount for some of the differences in spool?
