VA S4 RX-7 Turbo II UIM block off for coolant to turbo

So i just blocked off the coolant ports using freeze plugs under my UIM. The question I have is The port on the UIM where the coolant line goes to the turbo. Does anyone make a block off plate for this? The bolts holes seem to be about 1.5 inches apart. Do i need to block it since I have already blocked the coolant passage to UIM? I might have to figure out to create my own, but I have limited tools. I am going to research that and see about that option. If you have any ideas please let me know.

The reason I blocked those ports is because of leaking and I re routed coolant to the turbo a different route.

So the plate just above this is the Split Air Pipe block off I believe. ??? It looks to be the save size about. The threads are 1.5 inches apart also. Maybe I will order one of these to put here. Chime in if you have ideas or so I know I am on the right track.

you don't need to block it off. you already plugged the passage, just leave it open.

unless you want it neat, which is why most of the ports get block offs.

Yeah I thought it looked a little crappy to be honest. I was thinking it was just for looks and didn't matter though. I put some jbweld in that hole on the cover and put it back on. It looks a lot better that way. I got a little crazy and jbwelded all these vacumm ports I was no longer using as well.

Just out of interest where do you route coolant to the turbo from? I recently bought another FC and it was rebuilt with non turbo housing so there's no coolant feed to the stock turbo.

Thanks

So I have done quite a bit to my car. I plugged the rear iron coolant under the UIM. I am running coolant from under the filler neck and the thermostat. I have no coolant going to my UIM anymore either.
