do all turbos (TA that is) need the newer carbon seal? Anyone selling them in bulk as of yet? I was leaning towards a 62 with a 3000 stall converter for a long time, and now this topic has really piqued my interest!

Guess I needed a picture.
Read above Mark. He's got a few housings that that are TA units and has welded adaptors to them. Not the 86-87 turbos but units from the upgrades to the 86-87 IC cars.:biggrin:
I'd buy it for a dollar.:biggrin: LOL

thats right, Im getting the covers adding the O-ring adapter then machining the housing for what ever size wheel desired.
here soon we will be getting the first batch of T04E and T04S carbon seal backing plates. so the size of the turbo will be increasing here soon!

Looks nice.
If you look at the first pic, you notice that that adapter is concentric to the compressor outlet.
While it fits on the manifold, the exhaust /up-pipe will most likely need to be adjusted.
Here is why I say that.
The stock HA and IC compressor housing have different diameters.
The concetric alignment of the larger IC housing, moves the turbo centerline.
Yes, it shout fit, but it would angle the TB in relation to the original angle, after evrything is bolted together.
To keep the alignment of the TB square to the motor centerline, the turbo centerline needs to move forward.
This of course, creates stress (pushing it fwd) on up-pipe/PS header, which crack by themselves anyway.
Now, if you angle the TB as "bolt everything in place", the face of the up-pipe connection would be angled. (Not sure how much it would be, since I never tried this upgrade)
That too creates problems and leaks.
Just wanted to share my thinking on the keyboard.
All in all, NCE WORK!
This is what my dad fabbed up for my brothers 85gn...
If you look closely at the picture, you will notice that the adapter is offset on the compressor outlet to compensate for the larger housing.

Oh yeah ...........
Since the TA49 and TA33 have the same wheels, with the only difference being the slightly larger turbine housing, I am not sure how much benefit a TA49 will give for the work required at boost levels 20 and below.
I would LOVE to see back to back comparison testing.

I did have this on the car for a while till the turbo seal went, then the car sat for a LONGGG time, life kinda took its place for a while... (new wife taking up most of the time, along with new house, 2 babies to keep up with, side jobs etc, )
But yeah, I had to reclock the turbine housing to the compressor housing, no big deal, I believe I had to use a 86/87 actuator also, I forget why though... As for keeping the tb aligned, I have to say you would have to have or make an adapter like I did to square it up, I can't believe you could "flex" the turbo enough to make it look straight.
As for the polishing, Wacos pictures really came out good, my pics do no justice with the lighting enviorment in my basement, but man, I spent a whole week sanding ALL the aluminum under my hood down starting from 120 grit up to 600, then I found out they make a sweet little scotchbrite pad for a die grinder that works super fast for knocking down virgin cast aluminum to almost ready for polish. Then get some buffing wheels for a die grinder and some black, red and white rouge and buff, buff, buff, where a mask and glasses though, you WILL get dirty doing this. really dirty...
I also got a small bar of 100% carnuba wax, super hard stuff, looks like a bar of soap, got it off of ebay, and buff this on your parts with a clean buff, its the only way to apply it, and it puts a nice protective coat on the metal if you are afraid of clear peeling off of your hard worked metal. I was afraid of spraying any coating on because that was ALOT of work to make it look so good.
