Replace Rear Housing

[MaccaD2191]

Hey everybody, I have a garrett 3076 external wastegate version ( not sure on the a/r) and was wondering where I can purchase a different rear housing? Im wanting to go to a internal wastegate.. I've heard this is possible, please correct me if I'm wrong. Bit of a noob when it comes to turbos.

Thanks for any help in advance.

We can machine you a IWG .82 rear housing that has a 6 bolt Nissan pattern on the rear, with actuator with bracket supplied, plus the exhaust manifold spacer. In total you will be looking to spend $600.

I should probably give a bit more info.

I recently purchased a GTT which came with a - but not installed - HKS 3037 external wastegate version (56 trim?). Which apparently is exactly the same as a Garrett 3076R. Also got a Trust exhaust manifold for an external gate setup.

So far from the research I've done, it would be simpler and cheaper just to stay with an internal gate system, which is the reason for my original question.

Or would I be better off going the external gate route.?

Stao has just told you what going internal gate would cost. Price an external gate plus some fab work then do some maths. we dont know what is better for you

[MaccaD2191]

Yes I realize what I have already been told. But about which route I should take is where I'm not sure on. I've read that an internal gate can be restrictive on how much boost can be run and that a .82 internal gate housing will spool slower than if it was an external gate setup instead.. Is this true? Im looking for a fun street use setup that will go well on the track aswell. And money isnt the biggest issue.

I might be a able to split my .82 internal gate garret rear and dump pipe and actautor if the turbo doesnt sell complete.

That would do what you want.

hks 3037 had the cropped turbine wheel iirc

so a standard gt30 rear end won't work

Hmm. I think you are right.

It would bolt on though!

So using Bens rear housing won't work, I take it this won't work either?

Would the hypergear one work or would I better off just using what I have and going the external gate route?

That's what I have.

Hypergear should be able to machine a hkusing to suit your turbo.

[MaccaD2191]

Okay so I'll keep that in mind that I'll be looking at about $600 for an internal gate rear housing.

Now, what I'd also like to know, seeing as I already have the manifold for it, what are the pros and cons of internal vs external gate in this particular set up? Besides the fact I'll need to buy an external gate and the fab work.
Can one handle more boost than the other? Or is one laggier than the other?

I was running 20psi through the Garrett internal housing on a 25 but it had no chance controlling boost with the 30 at 16psi

Sell hks turbo complete buy bens gt3076r. Hks gt3037 has a cropped exhaust wheel as stated above. Same as the gt2835.

That's genius!

If you were considering a housing for 600 a whole turbo for 1250 makes sense. Approx 500o k's use and includes dump pipe.

[Joshbigt62r]

I was seriously considering it but im going a high mount ext gate as I think itll match the plazmaman plenum better I think. But op should def buy and sell the hks. Wont lose money as the hks 3037's still get $1000+ mark.

[MaccaD2191]

Ok so my HKS 3037 is more like a GT2835...? How does this compare to a 3076r?

I'll keep that in mind though mate about buying yours

[89CAL]

No, they are just saying that the HKS turbos used a cropped wheel. So the 2835 is a cropped 3071, the 3037 i believe is a cropped 3076

HKS 3037 and 2835 are two completely different turbos, the 3037 will deliver more power with more lag.

[MaccaD2191]

Ah yes sorry read that wrong.

Thanks everyone for the info, haven't fully decided which way ill go just yet but you've been very helpful
