The Project Pad

Dace,
Personally,i never found that ring on my Wagner RS2 'EM KKK flange before.If you can wait,I'll be having the brand new Wagner

'EM arrived within a couple days.I'll take some photos of the 'EM for you.

Ok Pop, thanks. It's not a big deal really. It's being omitted altogether. Dave fabbed a bracket to better support the turbo. That will be nice to not have to worry about losing exhaust hardware.

I had this happen on a customers manifold. I lathed out a new one in stainless and pressed it in. No big deal.

Any thoughts on what caused it in the first place Hank?

Yeah, I don't know. That insert is a copper alloy of some sort. Super soft. I think it ends up fusing to the exhaust housing and then partially pulling out hwen you pull the hotside off. Just poor material selection if I had to guess.

OK Dace.I'll take some photos for you though.

@Hank,Wondering if you can do some 'EM for the KKK Flange.

I'm thinking to give it more breather than Wagner RS2 'EM.

Pop, if you're interested in getting into a different manifold, then ditch the KKK hot side for a v-banded one. That is way more versatile, and easier to work on. Although I'm pretty sure Hank can build just about anything...

Uuuuupdaaaaaaaates? I wanna know how the 3073 is... for... personal reasons

Sorry to take so long to get to this! I bin travellin'!

So far, I really like this turbo. I have to say that I haven't really put the screws to it yet as I've still been breaking in the engine. Now that I've hit the point where I feel like I can start to get after it more I will really get to know it more.

That being said, the HTA 3073 with a .82 hotside spools at least the same as my plain ol' gt3071r with a .63 hotside. I'll give you more updates as I get to know this thing better.

I really want to get thing thing tuned right to be able to get the most out of it.

Oh Marc....

Awesome. I'll probably go HTA3071 on my build, not sure about .63 vs .8 yet.

On my car, the .63 didn't run out of air up top. It did come on a little too quickly down low for the way my car breathed, which caused some of the surge issues I was having. Any higher than ~20-22psi and it had some problems so I just set the boost level there. I did like the responsiveness of the smaller housing though. When ripping in the twisties it really kept the power available.

Matt somewhat asked me this in PM, so I'll let it go here since he is listening.

I think the HTA3073 is an awesome turbo on paper. It really is a turbo that wants to be pushed in the 30+ range though. It has the flow capability to make 450whp, or about where the 30r turbine in a .82 AR housing starts to run out of air. With any of the 30r framed turbos, you are limited by the smallish turbine. This means you just have to decide what kind of boost you want to run.

HTA3076r, Plan on that turbo running out of breath above 6500 on a 2.2L above 30psi. It just doesn't have the flow capacity. That said, it does have the flow capacity on the turbine side to support 28psi to redline. This means that spikes to 35psi at torque peak are going to be meaty and much higher than the smaller HTA wheels. It is going to be laggier than the hta3071 and 3073. Hardly anybody does it, but you could put a 1.03 housing on a HTA3076r or GTX for that matter, and have near 35r flow rates from the turbine(if the 35r is on a .82). I'll probably test this on my 2.6L at some point.

HTA3071r, this turbo has a smaller compressor inducer than the regular 3071r, but more surface area makes it outflow the 3071r. Still a tad undersized for the flow potential of the 30r turbine. You would have to beat on it to make 450whp. Good news is that hte 3071r has an awesome compressor map, and I bet the HTA version would be somewhat the same, allowing for as much boost as the engine will eat. To make 450whp, I bet you woud have to run 38psi at torque peak and it would taper to around 24psi by redline. Pretty much you wouldn't need a WG.

HTA 3073r, Probably the best match for the 30r wheel. Pretty much has the same inducer as the 2071r, but a larger exducer. Probably comes close to 3076r power non billet, but spools in that 3400 sweet spot.

Can't wait to see how it makes power on a 2.2L!

Thanks for that info Hank and Dace. Good to know the .63 didn't fall off - I had read that other places as well, it only amounted to 10-15whp or so up high but gave ~350rpm in spool. I won't hijack anymore, but I'm thinking HTA3576 with QSV... mmmmm

3576+QSV= :woowoo:

I think the GTX3576r is a little better option. I think the HTA76r lacks the top end needed to make the 35r turbine worth it. Cool thing about the GTX 76 is that it flows pretty much identical to the gt3582r wheel, but for 40 grams less weight. The ~59lbs the hta76 is rated at just isn't big enough to rationalize the bigger turbine.



I really wish garrett would come out with a GT32r wheel to fill the 500whp gap of turbos. You either have to overspin a 30r turbine to get that power, or underspin a 35r to get there.

Hmm, that looks nice. LOL hank you need more tabs open!

Holy crapola, found this: http://forums.evolutionm.net/evo-dyno-t ... 3576r.html" onclick="window.open(this.href);return false;

gtx3576 appears to be quite the turbo.

edit: so, the two "more" ideal options/better matches would be HTA30r or gtx3576, then. Wonder about the HTA30r with 1.0 hotside and QSV. Guh... so many options

My wife HATES when I have tabs open... Back on topic, that is offtopic...

Yes, that is what i would expect from the 3576r GTX. The Turbine on the 35r is very neat. It doesn't weight that much more than a 30r turbine. The bearing and seals are idencial, so you are carrying just more flow capacity with minimal weight in the gtx3576r. I would love to run one wide open..

Truth be told, this is kindof the hta3582r trick. The GTX is a 58mm inducer, 76.6 exducer with extended tip almost to 80mm. The HTA is slightly smaller than 60mm inducer, 82 exducer with no ET... We shouldn't be surprised that the gtx3576r is spooling close to 30r levels, as that is basically what the hta3582r does.

So my recently rebuilt engine(5k mi) is using About a quart every 1k mi. Sux. There is no evidence of it going anywhere. It's not in the catch can, exhaust, intake or outside the motor. Leak down is 3% across all the cylinders. The engine runs great. The turbo makes no strange noises and is only 25k mi old.

This shit is baffling. Where the hell could the oil be going?

up in smoke?

What pistons again?

Ross pistons. 83mm.

The turbo is getting pulled to look closer into that part but I can't imagine how that could be the cause with so few mikes on it

Did your seals seat properly? Does it smell like burning oil?

How is your catch can setup?

There's no oil smell.

The can is vented to atmosphere off the crankcase "octopus" as I call it. The PCV to intake is also sealed.

I didn't think you were supposed to seal the PCV.... I thought it was supposed to breathe to atmosphere also if you were getting rid of it. As it helps vent the system of gases that can gel/sludge oil.
