Thanks for posting up! Can't wait to the dyno results.
I'd also like more info on that intake manifold.
I am also anxious about it.
Below some photos of the intake manifold and the header.
Both are top stuff really.
Fabricated from a Greek tuner named Kakarakis. You will be impressed if you check his fb site.
I was very skeptical before purchasing an intake as I didn't want to sacrifice spool up at all.
This thing really works and makes also a deep induction noise like Weber carburator....
That looks very well designed. Do you know the total plenum volume?
It should be close to 5.5lt.
The runners are quite long and have the shape of venture. I think that helps a lot.
I know that there have been extensive discussions about intake plenums... I was very skeptical too.
This intake is not cheap but really works well allowing the engine to breath property, just my two cents
That’s a awesome looking intake manifold!! Not only is it designed well but looks very nice too! Looking forward to seeing your results. BTW always liked the evo 6 !

What AR was on the gtx3582r? Single scroll? Vband?

Last week we finished the instalation of a G30 770 with 0.83 on my Evo 6.
The car has a fully forged 2.0 LR engine with oversized valves, 278/274 hks cams and a hand made intake plenum.
Moving from a Gtx3582r to G turbo have to say that feels like day and night. Massive response and instant torque.
Due to Corona virus restrictions we haven't managed to Dyno tune the car yet but only with some street tuning and 1.5bar car feels a lot faster.
Full boost is just before 4500rpm and keeps the power all the way up to 8500rpm.
Of course the Dyno will show all the truth but as of now full boost have dropped by almost 1000rpm and Dyno butt is feeling very fast.
Flow is flow, Exhaust pressure is not debatable. Turbo cars benefit with a bigger exhaust.
Put a bung and a back pressure sensor to prove me wrong.
Why anyone would chose to neck down when the outlet is 3.5 is choosing to use an inferior setup.

I've seen testing and discussed it with people that have tested it. 3 to 3.5 at 850-900whp was 2psi difference in the down pipe (5psi vs 7psi), and did not help power. It helps to have a 3.5" cat back though, but I think thats because of the muffler causing turbulence more so than the exhaust tubing being an issue.
You want me to show you 3.5 isn't needed. But can you show me that it is needed? Can you prove your statement that it is indeed inferior? Because the testing I've seen doesn't show that.
Additionally the outlet of the Gseries isn't 3.5", it uses a 3.5" vband clamp/flange, which means the OD of the flange is approximately 3.5". The ID however is 3", if not a bit smaller.
Funny thats the opposite of where I see cars like the mclaren v8's and others that actually have a bigger DP for turbulence and a smaller catback. Aaron agreed with me at the time and so has Lucas making a 3.5 dp on his car in the past.

I agree with you letsgetthisdone.
In my case we used a down pipe of 76mm and at the v band clamp at the back we increased it to 80mm.
Hot exhaust gases travel faster near the exist of the turbo as they travel backwards they cool down and having a bigger dia helps

Nice car and right selection of parts.
Is there enough space to work with tightening the bolts on exhaust manifold ?
Can we compare this turbo with precision 6062 gen2 ?
Thanks man.
It's a tight fit, but with some patient you can do everything. When installing the header the water radiator has to be removed. We first fit the turbo on the header outside the car and then you move on installing and tightening it on the block...
G30 770 is a smaller turbine (physical wise) than 6062 as it has 58/71 compressor and 55/60 hot side, meaning that should be more responsive.
What still has to be proven is the power rate that Garrett is claiming.
If everything goes well with Corona virus in couple of weeks we will Dyno tune the car.
The plan is to push the turbine at it's limits using pump gas 100oct (European fuel).
Fingers crossed the thing looks very promising
