Gtx 3076r gen 2 vs gtx3582r gen 2 ej207

[Mauled]

Alright here's my question if I get the 3582 gtx what ar should I run to hit 500whp, .63 or .82? I have 264 cams and can I turn the rpm limit to 8500?

.82 should do it. Do you have upgraded valve springs and retainers as well? How about rod bolts? When I had my block built I was told arp 2000 are good for 8k and above that you'd want arp +625 but that was for an ej257. The ej207 has an 8k rev limit right? You could always up the rev limit and see if it still makes power past 8k. Why not try the 3576r though like other people have suggested?

3576 Gen 2 is worth looking into if you aren't going G series. I have one in my garage, it's a great turbo.

G30 770 should beat it for spool though

.82 will hold power up top longer

How about this guy?

[K3rm1tth3fr0g]

Does not share the same TW specs as the aforementioned G30 770.

G30-770:

Compressor: 58mm/71mm
Turbine: 60mm/55mm

5862G:

Compressor Wheel: 58mm/71mm
Turbine Wheel: 68/62mm

And what do ya know?

Almost exactly as I stated, the knock off comes in at most of the cost of the real unit.

This is even more true with the ultra cutting edge tech like the G series....

770s can be had for ~$1800 and this unit is $1059

Up to the user if those savings are worth receiving worse support, and experiencing overall lowered performance.

[HughGordon]

I know it's not the same turbine wheel, that's why I think it's an interesting turbo. Similar to the 3576 gen ii but with a smaller exducer on the compressor vs the g35-900 which is the successor and has a larger inducer in comparison to the 58/76 wheel on the 3576. Garrett doesn't offer that specific wheel combo. Also, can show me where you can buy a G30-770 for $1800? Because all I can find are supercores for that price.

Yeah fully built heads gsc billet cams and arp 625. When I pulled the heads off the cylinders looked perfect so I didn't split the block, still stock version 8 bottom end.

Here is the turbo I have now: https://www.ebay.com/itm/174006332113?hash=item288395ead1:g:jw4AAOSwFpddX3M 4&amdata=enc%3AAQAIAAABAE6YKQz5eMB2ezHPP%2BdRiVTSZ MHITCmCYWhrUJqLrBR0wswLtkvxe%2FUEg4G30IYnLhxN%2Bt1 Slt6I400YkE1joS0mOGICH%2BrVpbJbpfgFBJxrXV%2BpPW3YF HuouVRM8LZjdM%2B6%2FxTdC7RYfhhvNcL6QUnbXOGvRoyE2bW KAAfWf7ldw1G6toWIH41NfVzzqzz1J4TGE4L3zvFLYO05chIvh hE3aq%2B4cfQM84CgZHkh3mVIu%2FRZLPT4QlebzqhE0K7WVGx 8t7UPtBSjShlri2VzE2fN8%2FUW6ONHKk%2Br7gvQzE53wqrQH 41GQECVFQe9XypjpJZbUjU4VETH%2BDKgfbJvzY4%3D%7Ctkp% 3ABFBMypryzopi

Like fuji said I don't think the 3576 will hit 500whp unless I use 30psi of boost. Figured if I'm going to get a bigger turbo the next step up is 35r.

[HughGordon]

How about a G35-900 clone from that same company? Or is that too pricey? Similar flow-wise to the 3582 but more efficient.

I'm sorry for going off on you yesterday Kermit.

You're upset because the gaskets that came with were bad....?

Who uses included gaskets anyway?

Hahaha - no one is gatekeeping anything.

That is rich coming from a goober who contributes nothing to the forum.

It would have to be t3 4 bolt instead of v band, I have the perrin rotated uppipe and downpipe. I'll have to see if I can find one and look up more data on the turbo.

Maybe you can fit an adapter in there? I don't think you can get a G-series with the 4 bolt, even clones. I had Joey at CustomFabShop.com make me an adapter that goes v-band turbo exhaust to stock Subaru downpipe flange. Nice guy and does good work, he can make any flange or adapter that you can think of.

Please show me where I can get a new g30-770 with turbine housing for $1700.

G30 770 is the ultimate SWEET spot for ~500+

Gt30 spool and response with gt35 power

Can the G30 770 fit in stock location?

[HughGordon]

You can make it fit with adapters. OP has a rotated setup though.

no you're going to have to go rotated, the g series are a lot bigger and heavier than the gtx series

Not true. They are almost identical in size. Yes in most cases you'd have to go rotated unless you have some adapters fabricated and grind your block.

I remember Killer B was working on a Spoolinator for the G series but they said that the housing had extra features that stopped it from fitting. I don't know which G series turbo that was for. Maybe another company makes a housing that would work?

Yeah I haven't seen any compact housings for G-series turbos yet. That doesn't mean you can't make a turbo with a 4 inch inlet fit though. I am currently running a 3576r gen II using adapters on the inlet, up-pipe, and downpipe. It just depends on how willing you are to grind at your block until it fits which most people probably aren't comfortable with.

The engineering costs millions of dollars. You think a bunch of PhDs who are experts in the fields of compressor and turbine aero, bearings, and rotor dynamics come cheap? Lots of money spent in testing and validation. Then more money spent in process development to manufacture a quality product.

Go ahead, keep on buying the knock offs. Companies like Garrett who actually develop new product will just stop. I've seen it happen to plenty of small aftermarket companies who were the innovators. The knock-offs drove them out of business and then people complain there's no new products coming out for their cars.

Has Borg Warner done anything since EFR? I saw a Pulsar knock-off of a GTX which has a very distinct turbine housing feature. I guarantee you Pulsar has no clue why Garrett made that feature; Pulsar just 3d scanned and copied.

Ok guys I'm bored of the 3076, I think I have it narrowed down. I'm going to get a 3582r, my question is what ar should I get for the 2.0l, .63 or .82?

The gtx gen 2 .82 3076r doesn't make full boost till almost 5k.

I'm thinking a gtx 3582r gen 2 with a .63 will give me more top end and keep my spool about the same, thoughts?

I'm also debating whether i should get the gtx or the regular gt3582r.

My old .63 gt3076r made full boost around 4.2k without the cams.

And would it be possible to safely turn my rev limiter up to 8500? I have beehive springs and 264 cam and arp 625, but stock bottom end. Motors been going strong with stock 5 speed tranny for 4 years but I don't track it.

Let me know your guys thoughts of what variant 3582r I should get. Has to be t3 with 4 bolt exhaust housing.

I think I'm pretty set on the gtx3582r .63 but wondering what you guys thought. Will it hit 500whp on 25psi?

Also if anyone knows a solid dyno tuner in south jersey let me know.

[Mauled]

Another question if I order the gtx 3582r .63 and don't like the hotside will the .82 hotside from the gtx3076r fit on the 35r?

[HughGordon]

I think that the gtx 3582r gen 2 with the .63 will meet your goals.
I would try upping the rev limiter and see if it still makes power past 8k, 264 cams might not make power that high up.
The .82 from the 3076 will not fit the 3582, they have different turbines. Turbine housings are pretty cheap though if you want to switch to a larger one.
