How easy is this? I want a t3/t4 hybrid but don't really feel like buying a whole new turbo since I already have a spare t3 in the garage. Can I just get a t4 compressor housing and swap it on with the correct compressor wheel? I like the t4 because they're supposed to flow a lot of air (according to other people around the intarweb)

What are the specs on a "t3/t4"? What turbos would you combine?

If everything clears it's a matter of swapping parts, and sending it out for balancing.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

Why not just keep surfing craigslist? I found a turbonetics T3/T4 60 A/R for $250 locally. I think I'm going the HX30 route instead though. My factory garrett is kaput. Too much high boost. (17psi steady, spike to 20psi while shifting)

Okay now I'm thinking of going HX30, who has one and how does it perform? How is spool up time compared to a stock Garrett?

My reason being is that a cheapo one can be had new for like $320 with free shipping on fleabay. And I'm tired of deliberating on this and need more air so I have an excuse to build sooopaaaahhhhhpuuuuuuuuummmmmppppppp

An HX30 is huge-when we put one on the tractor it turned 5psi at redline, the garrett hit 12psi.

But with a big pump you could probably get enough juice flowing to spin it up faster.

It spools slightly slower than stock, but not even enough to tell a difference really. My hx30 is only slightly larger than stock, inducer wise only about 1mm, but the exducer is what helps the map so much. Exhaust is bigger, but I didn't measure it to know for sure.

I'm still running stock pump, just turned up with no Alda. The turbo has an MWE groove, makes it sound awesome Big Grin

Not necessarily hole, but they have a ring around the comp wheel, then a space, then where the intake would clamp on. If you google MWE groove it'll pop up. Pretty cool how they work.

I did a little research, the ported shrouds have an MWE groove, and the holes in the comp housing provide the air to the MWE groove, instead of being open like most others

The achieve "anti surge" by making the compressor map wider, thus moving the surge line. They don't completely do away with surge, but it can help. And they whistle like crazy and sound awesome Big Grin

If your looking for an hx30 make sure you pay attention to the exhaust housing size, 7cm is the biggest I would consider for a stock pump 617. I have a 6cm on mine and that's what I would recommend for decent spool.

An he221 would be the bees knees for a 617, with a 5or 6cm housing. The only thing is you have to adapt it for a t2 or t25 (can't remember which)

After doing a bit of digging, it seems like ported housings are the old way of doing it, i.e. a shroud within a shroud. Like this:
[Image: dc7cf6c4.jpg]

The new way of doing it is to use a bell mouth and drill holes through it down to the mwe groove.
Like this:

Not sure why this is, is someone able to clear it up?

Or keep an eye out for an he221, they are very similar to a hx30 but outflow them by a couple lbs. plus you can get one with a little smaller housing. I'd probably rather have a 221 than a 30 on mine. But hey, It works Smile

Okay so next question, what to do about oil supply/drain for hx30? I doubt the stock stuff bolts up? I'm tired of the Garrett, time to go bigger, and I get paid next week. Also, can't turn up the pump until I get more boost, and I have a leaky oil filter housing gasket and figured that would be the perfect time to adjust the pump a little since I don't want to pull it a bunch of times

-1982 300D Turbo, 280k miles, ALDA apparently maxxed, fram 8038, 12 lbs boost, non-egr manifolds, W/M injection, 4 brake light mod, Gen II w126 front rotors/calipers, 4-speed swap
In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)
-1980 300SD, 110k, project car. Goal is to get it lookin' like it did on the showroom floor (body and interior wise, not necessarily under the hood )
-1974 240D, FRESH PAINT!!!!!!

(11-30-2013, 06:14 PM)hooblah The new way of doing it is to use a bell mouth and drill holes through it down to the mwe groove.

Not sure why this is, is someone able to clear it up?

To make it look pretty -> charge more money. Angel

You can google SMWE (=Super Map Width Enhancement).

Ported shroud housing takes efficiency out of compressor (as it bleeds air) and it should not be used because of looks or sound... Rolleyes

If you don't have surge problem, why use anti-surge housing and loose compressor efficiency (which means higher IAT/EMP)?

If you have a surge problem, then it might be reasonable. Cool Although for serious builds I'd do it electronically controlled.

The difference between anti-surge and non-anti-surge housing can be related to ancient and modern turbo design. It can be that big.

Shadowmaker is right (as always Wink)

Recirculating some of the air means compressing it more than once, this lowers the overall compressor efficiency. On some turbos like low trim, big compressors, not very noticeable (Holset HX35/40 and so on still have an amazing high compressor efficiency with these ports) while the best example for how bad it can be is the HE221W with very poor compressor efficiency but a very wide map for its compressor wheel size. The bigger the port or slots (the more air being recirculated) the lower the compressor efficiency will be.

If you have no surge issues without it, no need to add it if it isn't there already.

I can agree in some extent but I would be careful in making it a statement.
It is so dependent what you want to accomplish. simply I can not understand why the manufacture of turbos no not elaborate more with the swirls extent in the inlet for lower the aerodynamic load on blade in the compressor when surge is an issue, of course it would be more expensive. and buy using advance vane diffuser more aggressive outlet blade angles would be interesting so more the behaviour that pressure ratio can increase with flow and not becoming a limitation what do you think about that shadow

(03-12-2014, 03:51 PM)Turbo ...what do you think about that shadow

Of course there are experimental and race oriented turbos out there that aren't currently available for the masses. I have held turbo and ex-mani out of a WRC-Peugeot in my hand and with the prices they were quoted I'm sure they have very little in common with the turbos that can be bought from turbo shops. I bet new F1 turbos are utilizing things that we can only read from scientific studies plus then there is stuff that isn't even public yet.

Maybe 10-20 years time we are able to buy these currently state-of-the-art turbos, but meanwhile we need to either choose the best combination available or maybe even try to machine some cool things to those with public knowledge from turbo research. Our OM606 have used some of these findings already...

I really think the BorgWarner EFR 7064 would be a great match. It's internal waste gate and aerodynamics make it very attractive in my opinion. But is does cost 2K :-(
