What LIM is this?
Started pulling apart my project car today, it's an 88 NA with the airpump removed & ACV blocked off. First problem, my LIM isn't the same as other NA's I've seen or the FSM, there's nothing for the aux ports. Is the LIM off a T11 since they were 4 port?
2nd question, the big hose goes to the BAC, where does the small one go? It's the pipe between the throttle body & AFM.

Bunch of ignorant responses here. Its a Euro version. Your 6 port valves should be located on the top of the lower inatke real close to the irons/side plates, they are butterfly valves rather then rotary type valves that us U.S. Spec guys are used to.

I don't know about the U.S. upper and Euro lower bolt paterns. The Euro spec side housings are different indeed. The AUX ports aren't bored/machined like the U.S. spec because theres no rotary sleeve/valve. The port also doesn't dead end like the U.S. ones, but they have a more conventional ramp at the end/port shape simular to what the Pineapples sleeves imulate.

I just found this thread after getting confused myself. I'm in the UK with a UK s4 n/a and found these butterfly valves. Mine were seized anyway as I now find (just bought the car as a project so not driven it myself yet, it was cruised up the motorway to get to me now I've started stripping it).
It looks like the ports are both smooth internally, I can't see far enough down into the 5th and 6th ports but the ones below are nice and smooth into the chamber and the top ones seem to go further into the block where my torch and my eye can't both be at the same time lol.
Removing these is going to be the plan as the port is tiny and the butterfly takes up about 30% of the cross sectional area even when fully open. I know I'll lose a little low-end but thanks to the port in the block not needing a sleeve I hope it won't be as big a loss as you US guys get.
The actuators are on the top of the LIM with a very short rod onto a shaft to the butterfly. The vacuum hoses for the actuators seem to go up on top of the block, I can't tell where from exactly as I ripped off the rats nest and UIM already but I don't think they received any signal from the exhaust, especially since my exhaust hasn't got a cat from what I can tell, it just has this massive balloon manifold/header with an air pump inlet on the front end, maybe that's a cat itself I don't fricking know but I'm going to make my own header or buy a RB one anyway.
If anybody is curious I can take more pictures, and I suggest you guys look on www.mazdarotaryclub.com and www.ebay.co.uk if you are interested in getting a euro spec engine.
