ClassA4x4

I'm getting ready for this weekend install and from the instructions I found, I don't see the answer to one question of mine:

How do you separate the air intake hose flange from the old compressor housing?

The GDS housing that I have in the package does not have the intake hose flange, so I assume I have to reuse the one from the old housing. I just can't visualize how to separate them.

Thanks in advance.

Guessing you're putting in the 60mm upgrade.

You have the wrong housing. The intake horn is built into the Holset compressor housing.

While you're at it, unless your turbo is fairly fresh, this is a good time to put in a bearing and seal kit. By the time you get it open enough for a compressor upgrade, you're only 6 bolts and an oil line from having it on the bench.

Thanks for the advice. I'll call gds to send to send the correct housing, What a hassle, i have to send back the other one. Was it my fault? I thought I ordered one for a 93.

The Holset compressor housings supplied by GDS do not have the intake side flange. I have never had mine slip off.

I also have one, and the rubber boot just clamps on, it has not slipped any in 4 years.

Cougar, 1gfb, thanks for the followups. That helps.

The force on the boot is a suction force (negative pressure) not positive pressure, so it should stay unless it's being tugged by the filter, and mine in the motorhome might have a tendency to do that.

I can keep it and use it like you both do, but I think it's easy enough to make a lip at the end of it, much easier than shipping it back and bugging Steve at GDS. I just have to make sure no metal filings get inside the housing.

I thought you were missing the hose bib. I don't think you should modify it or worry about it. Unlike the discharge part, which will put 80 - 150 lbs of push off force, the force on this joint will be from 0 to minus little. An ordinary band clamp, especially the good ones used on these things, should prevent any accidental disconnect, even without the bump on the end of the connector.

Installed! 40psi at wot.

Works as expected.

Next week, the new torque converter install.

cool bean man, I love my 60MM.

Question:

If one were to machine the backing plate, could they run a wheel similar to a Super HX40 or an HE351CW?

BAE sells a 62mm wheel and compressor housing, but you need to machine the back plate for the wheel to fit. http://baeturbosystems.com/compresso...1-2-2-1-1.aspx
Might stress the shaft though with that big of a wheel.

The H1C has a very similar shaft to that of an HX40, doesn't it? Therefore a Super HX40-type wheel shouldn't stress the shaft more than it does a HX40.

What's the difference between BAE's 62mm wheel and compressor and GDS's 62mm wheel and compressor...besides $150?

1972RedNeck

GDS doesn't sell a wheel with a 62mm inducer - 60mm is the biggest.

GDS's only has a 82mm exducer while BAE's has an 86mm exducer.

I bought a turbo from BAE once. They told me it would take two weeks to get it to me. Three months later it showed up at my door. Less than 5,000 miles later it had over .010" of axial play.

In other words, I will never ever buy anything from BAE again - I will only use genuine turbos and parts.

Oh...well then what is this? Upgrade Compressor Housing & Wheel combo (60mm inducer) for 1991.5-1994 Turbochargers BAE claims that they're genuine Holset. Are you saying they're not? I'm just curious because I'm getting ready to do this upgrade.
