The turbo pulls more vacuum so there is more tension on the spring under the lid.

Yes it's a fairly simple 'engine' swap if you only swap the 22re longblock and exhaust. However the 91 intake is different than the 86. The 86 throttle body is down-turned therefore could not use the 91 cross-over duct since the 91 comes out horizontal. The duct from an early 22re would be required.
I'm interested in the theory of the 22RTE distributor as it's my indication the distributors are the same, at least with regards to an 86 22RE. The timing on a 22RTE is handled by the ECU similarly to the 22RE- by the ECU maps. The 91 distributor is a different part number, but not because of the timing curve being handled by the distributor- different hall-effect pickups.
22R distributors have adjustable plates to respond to varying vacuum conditions in the engine.
The AFM may be a valid point due to the increased air flow (not vacuum) required by the turbo. This would mean though, that the turbo afm is calibrated is differently... however a part number cross-reference suggests that the 86 22RTE uses the same air-flow meter as an 86 22RE, thus negating that claim.
Not trying to be the south end of a north-bound mule, but what you said (which I addressed) appears incorrect.
