Hey all.
I'm currently rebuilding what I think is a stock T3 Airesearch turbo using a fairly standard t3/t4 rebuild kit off of ebay. The issue I'm running into is the turbo back plate is sealed using a 4 piece carbon seal (example https://www.gpopshop.com/t3-t4-seals.html) which doesn't seem to be compatible with the standard turbo rebuild kits out there. Those kits use a dynamic seal thrust collar which is too wide to fit through the center opening of the turbo backplate.
Right now my options are:
1. Source a different t3 turbo backplate to complete the rebuild using the rebuild kit I have. Looking on ebay it's easy to find "t3 back plates" but the measurements don't match up to mine (total diameter, compressor wheel size etc)
2. Source a new core turbo entirely
3. Find a new rebuild kit with the 4 piece carbon seal. The seal on this turbo was cracked and my understanding is that they're very fragile generally
Right now I think (1) is my best bet, maybe using merkur parts midwest though their site is down at the moment. For what it's worth, I'm planning to use a compressor wheel from a stock Grand National turbo with this rebuild. Anyone have experience rebuilding a turbo on these cars?

Re: t3 rebuild
Did you contact GPopshop for your seal? I'm sure if you contact them and explain what your situation, they have what is required to make it work.
Re: t3 rebuild
Hi all,
I tried to drop by to visit with the folks at that shop (in the poorly signed or marked back roads of AR) when going on a road trip to MO and they were not there when I arrived. Clearly they are not there every day so if there is a delay in response it is also clear that they really are in business just not there as an 8-5 M-F schedule. It was not my day as I also tried to visit with an Airstream repair shop in the same area and they were not there that day either. !! It was a Friday so they both took a long weekend, I guess.
I would recommend letting GPop rebuild as they can make the T3 have a bearing instead of a bushing from what I have read on their site. I stopped by to try to discuss making mine a T3/4 hybrid with a bearing instead of a bushing. Still need to do that and will address this issue in the coming months.
Cheers
