Did all 2.2/2.5 tubo motors from the late 80's early to mid 90's have port for port fuel injection? And everything else a throttle body? cant find any around here to look at so having to buy the mainfold blindly..

Yes all the Turbo 2.2/2.5 were multiport injection. NA cars were throttle body (or carb for the earlier ones).
Keep in mind, there were three different manifold styles used on the turbo cars.
From 84-87 was a suck-through log manifold (the TB was mounted to the inlet of the turbo and the intake was a poorly flowing short runner "log" of aluminum)
In 86, on the intercooled GLH-S, the 2-piece blow-through intake was introduced, which placed the TB after the turbo. Supposedly the best flowing intake offered on the SOHC turbo motors. This intake was also used on the 87 Dodge cars with the intercooled 2.2L motors.
In 88, the slightly shorter, 1-piece blow-through intake was introduced across the board for the 2.2 and 2.5L turbo motors. The non-intercooled motors received silver intakes, intercooled motors received black wrinkle finish.
Adding to the confusion, there was a port injected non-turbo motor created. Using the later 1-piece intake with a stainless steel fuel rail and slightly larger fuel injectors for use with ethanol in the FFV (Flexible Fuel Vehicles) luckily they were mostly used by government agencies as they were fleet purchases.
The 3.0L V-6 motors used nearly the same throttle bodies, just slightly larger in bore, which many consider an upgrade, though usually they just cause idle issues and a touchy throttle.
The n/a 2.5 in my Mother's old Acclaim was TBI.

as I recall our '87 plymoth horizon (only car my family ever bought new... fully loaded for $6k included a/c and an am/fm radio... also first car I ever drove... and broke the shift linkage in when I did haha)
anyway it had a carb... recall dad doing a few carb rebuilds on it in it's tenure as our family car... but it wasn't turbo obviously
my '85 shelby charger had the turbo I with the crappy style blow though... I had a nicely modified 3rd type intake from a TII but had to sell the car before it ever got on.
Good info - thanks.. Got a simple 2.5 engine with the throttle body that I would like to change to multi port with megasquirt.. figured it would be an easy enough car to try it out on before I tackle somthing more complex. thanks!
Yep, it certainly would be. Uses a lot of fairly standard Bosch pieces. The injectors are low-impedence, so you'd need to deal with that on your build (depending on the version of MS you use)
I knew a guy in Washington that built an Omni with a 2.2 and a turbo intake. Got around 40mpg on the highway by leaning the heck out of it and driving very carefully. Kinda impressive for an old box.
