Silverfox (Dan Gilsdorf) built my 4R70 and he simply locked the pressure. No adjustment at all. It runs 220-240psi around 3000rpm.

The way I looked at it when I was choosing how much I wanted to spend was that these little suckers are the lifeblood of keeping each cylinder cool and in sync with all the other cylinders. If one...

Ed,
Is the MS PnP compatible with his 2V computer? If it is then I agree that it's a great direction for his wallet to lean towards but only if he as the knowledge or the availability to get it...

Since we were on the topic of oil drains do you have, or will it help to have, drain extensions on the bottom of the turbos? I made mine after fighting access to the fittings on the bottom if the...

hhmmm.... :hmm:

I would imagine the screw will require more HP to drive it and it would probably depend on the boost it was trying to force down the throat of the motor. The main HP differences between our cars may...

My tuner uses these a lot for the cars he builds so for comparison here's the one's I bought:...

How much power you wanting to make?

Thnx, I know about the clearance issues between the two housings. I had to grind a bit of clearance on the aluminum ones I made right at the welds. This time around I'm using thinner flanges and if I...

Currently Brian has the turbos for rebuilding but he said that he wants to run them on his car first to see if they leak. Either way I want them freshened up before they go back on my car.

I agree...

With the draining issues I have been having using -10 drain lines and a large scavenge pump I keep hearing over and over that a -10 may not be large enough.

Here's my solution: I am making all new...

You will LOVE having this option! I predict that it will save you having to walk to an E85 gas station more than once!

As an FYI, I also checked the E85 measurement that MS shows to a E85 test kit...

For a turbo application I would leave it alone. I'm sure your TFS heads flow more than my ported heads and you won't be lacking in power when it's all done.

I wasn't quite sure what you actually did to adjust for TDC but it sounded like you adjusted the computer settings so the balancer mark matched the timing cover?
If so do not do this. Find TDC and...

For the timing cover I would remove it and weld a bung or two in it. With the turbos off most of the work is already done but I took a quick peek and there's not a lot of room on the front to choose...

Good info.. I will check into plan B which is to pull the timing cover off and and weld a bung or two there instead. I'm not sure if this is a good idea just yet or if it's even doable so still...

It's UPR and there seems to be some good distance between the K and the pan but like you said I'm not sure about the pickup. I wonder if the pickup bolts can be accessed to disconnect it once the pan...

On my 2V what are the chances that I can drop the oil pan w/o messing with the Tubular-K or lifting the motor?
The pan is an unknown 8qt unit.

If it's doable I may drop the pan and install some...

I'd use a -20 but unfortunately the fitting in the pan is only a -8 so that is my limitation but I do have large ID steel tubing feeding the s-pump. I had some -10 laying around and the ID was a...

See link in above post but they are mounted high right in front of the valve covers. Bottom of the S-pump is towards the bottom of the radiator about 12" lower than the bottom of the turbos.

Not sure what you're asking but they are in my garage right now but when installed:

Thanks Ed. Sorry to cause you to visit the bottom of the bucket on a Sunday afternoon.. ;)

The drains coming out of the turbos are 5/8" od x .035 wall steel lines. These lines feed into a...

The turbos are still leaking so they are boxed up and getting shipped back to him but he's being snippy b/c he says they aren't the problem. Despite his feelings he's getting them anyway so hopefully...

Yep, I agree and to quote Sherlock Holmes:

…when you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.

Yea, full length with 3 mufflers which all had to be cut off and replaced. I used 8gal of gasoline and 2 cases of brake cleaner cleaning out the exhaust pipes, IC and inlet pipes. The oil in the DP's...

Still got oil in the exhaust so I'm sending turbos back to have them freshened up. I installed a much larger scavenge pump, new oil pressure gauge for adjusting the oil psi to the turbos, readjusted...

No clue. I think there is just a spring and check ball inside.

ks

Yea, that's what I've been told. Just a piston ring and good drains.

Good news so far tonight. Oil psi to the turbos was adjusted to 20psi cold and the car ran for about 15 minutes and so far no...

It seems that all over the forums the agreement is that once turbo seals start to leak they never seal up again. For years I’ve read that if the oil feeding the turbos isn’t limited or if the oil...

Right now I'm good. If they leak after this weekend they'll be going back to Brian.
After this fiasco I wish I knew what rebuild kit to buy. I watched a few vids and the parts don't seem toooo...

Gotcha!

If the fuel rails are not already connected I would suggest connecting both fuel rails together.

Ooo... I thought I was going to get a key to the Teachers Lounge!

I don't have the privileges to view your link "Potential Pic Post Fix".

Your screen shots of the second and third images look different than mine and it still doesn't work.

Unfortunately I don't even think he remembers what parts was used to build these units without seeing them plus I'm not sure I want to deal with him anymore on them after this weekends fiasco with...

I'm all ears but:
How do I know what cartridge to buy?
Where would I even get such a thing?
Do they come with the exhaust wheels and shaft or just the center section/housing?
If they come with...

I have no clue, I don't know anything about rebuilding turbos. I just want these gone through and I'd rather have someone experienced to do it for me. I also think these have been balanced if that...

I will also emphasize your comment above about non-stainless exhaust rusting: I built my entire system from new mild steel then had it ceramic coated inside and out from Jet Hot coatings. Within a...

Thanks Ed,
I knew about the additional water but I've never had the car idling this long to see how much actually comes out the tail pipes. Once the water on the floor evaporated there was no stain...

My current turbo gent won't freshen mine up so I want to send them to someone who will. Just needs some seals and minor cleaning.
Any recommendations?
