Yes the pan is thicker than a stock pan, but the edges of the pan remain within the bounds of the trans; the pan does not stick out past the trans.

Gotcha so it isn't a stock pan, Looks like some massaging and your in business. Get Leo's kit on and then whatever needs modified by us for your setup we can do in one swoop be it feed pipe, down pipe or cold side.

Also he will beusing thermal wrapp and turbo blankets which come in the kit

 

[TexasBlownV8]

What gets the wrap? ..almost forgot about that!!!!

 

[Bobby]

Here is what i did. I would do the pipes going to the turbo and thats all. You want all the heat to stay in there and then coll down asap on the exit side of the turbine.

 

[TexasBlownV8]

Makes perfect sense. It's one of those steps that is easy to forget.
Are there metal tie straps in with the wrap? I haven't looked.

Also, is the metal gasket between the turbine and pipe re-usable? I removed the a/r housing from my pipe, but am putting it back on. The gasket is compressed flat now. I would think it is ok to reuse it since it has not seen heat.

 

[Bobby]

I think i put in a couple of warm gear clamps. That what i use instead of the metal tie straps. They hold on better. Yes they are reusable.

 

[TexasBlownV8]

Ah, so that's what those clamps are for! Very good idea, I'll have to remember that solution to holding down wrap

 

[TexasBlownV8]

Is it even worth wrapping the pipes as short as they are? There's 6-8" of length of wrappable pipe section on the driver side; not counting the full length from manifold to bottom of turbine connection (which would be hard to get completely covered anyways). I wrapped what I could, on the driver side section.

 

[Bobby]

Yes. I say every little bit helps. But you can do what ever you want. No big deal. More heat stays in the pipe the faster the spool and more trq and power.

 

[TexasBlownV8]

Well one is already done, so I'll leave it on

 

[TexasBlownV8]

Did Leo's parts ship? We need them clamps, like yesterday!

 

[UltraKla$$ic]

PIC update or BAN!!!!!!!!!!!

 

[crownaviation]

Yes pics!

 

[TexasBlownV8]

pics? pics? I've posted some pics of generally where we are, i.e where the issues I'm seeing are. New pics will some when things start to fall in place.

 

[Bobby]

He means me. I messed up when i sent their stuff and forgot to send the vband clamps. They will have it by the end of the week

During the past week, I've been 'tinkering' with getting the turbos to fit under the car.
The driver side turbo is ON and in place to stay!
The fact is, the 4r70 is so much wider and takes up so much space, it would not fit without some modifications, to the trans bellhousing and to the turbo piping.
A sizable area of a part of the bellhousing had to be ground out, to make room for the turbo unit.
Also, the pipe at the manifold was not sitting at the correct angle, and in fact, preventing the placement I needed for the turbo. As such, I cut out a 1/4" wide wedge out of the pipe near the exhaust manifold, which allowed me to get it into the proper location and angle. This is likely due to the trans not allowing the piping to move more inward, and as such, the flange at the manifold was just at a non-usable angle.
So now that fits reasonably well, with reasonable clearances, although the pipes near the frame are close.

The passenger side is exhibiting slightly different issues: the front O2 sensor bung is in a position that absolutely will not work; there is an ear on the trans case, near the exhaust manifold, that is in the way, an part of the bellhousing is in the way. The sensor bung needs to move down-pipe about 1-1/4" and around toward more of the top by about 1" or so, making it sit straighter up in the pipe.
There is a section of the pipe where it branches off at the wastegate that will be very close to the side of the pan, and I may hammer that in a little to give it room.
The angle of the manifold flange is slightly off, too, but should not be enough to matter. The biggie is the o2 bung, so that will have to be corrected.

For trans cooling lines, I'm using -8an braided hoses, with 90* hose ends at the trans; this has allowed me to orient the lines so that they should clear the exhaust piping. And, running of the lines forward, I routed them higher up to near under the motor mount bracket and out to the body near the top of the a/c compressor; this gets them out of the way of the cold pipe that goes through there (which pose some minor issues as well).

In this process, I am completely ignoring the piping past the turbos, as those will require extensive modification as well to fit.

pics...

areas on driver side I had to cut and grind out: (Looking at these, I shouldn't have to do this to get this installed!)

Driver side turbo in place:

... the cold-side Y-pipe does not come close to the turbo outlet, with about 3" of separation there, like it is expecting the turbo to be turned more inward or moved move inward to the center of the car. Going to have to get a little piece of pipe or hose to make the transition, once I get the passenger side figured out, as it may need changing to fit, too.

Passenger side pipe needing altering:
- needed upstream O2 sensor location

- where the bung sits in relation to trans:

- the area where the sensor would try to fit into, pipes removed; there is no room for it there!!!

- area of the pipe that contacts the side of the trans/side of pan; a big hammer will have to make that happen:

So far EVERY hot side pipe DOES NOT FIT without modification. There simply isn't the room to position the turbo assemblies like where they woudl normally go with more available room. The "downpipes" going out will not fit either, not the driver one where it is now and not the passenger side one where I plan to mount the turbo; those pipes aren't even close! I'll have to make them fit or just get the pieces and fab up what I need. It's getting old (and frustrating) cutting pipes or making other alterations to pipes that should fit, but because of where I'm having to mount the turbos, the hot-side pipes are not fitting as-is. A "4 hour install" is taking 4 weeks, or 4 months, and only part of one side is in place so far.
I'm going to spend my Saturday afternoon altering the turbo pipe, making it so it will fit my car, and trying to get the passenger side in place, like the driver side is now. Then I'll fight with the y-pipe, see what that needs for it to connect to both turbos. I already know it runs through to up front, as a tight/close fit and gets in the vicinity of the driver-side turbo, but there is a route and path for it at least. I just hope it fits the passenger side where it shows it to go, in relation to the k-member.

Yea, 4 hours isn't happening...only way i see this being remotely possible is with a lift..I think we're going to be at it again most of Sunday and still not finish one of the cars.
I'll be happy when both of our cars are finished though..but it is certainly a tough and exhausting ride.

You can't blame S&H and the kit, you knew going into this you were going to be a guinea pig because of your 4R70 trans. From installing your 4R70 you also know how little room there is under there to add 2 big turbos. I hope you get everything worked out.

So have yall put it on leos car yet. He has a tr6060. Just linke my car which it was desigined on.
