throttle body vs multiport injection

[dgsmooth]

cheers again - wondering if fieros ever came with throttle body injection? I thought all fuel injected ones were multiport? reason is im looking at another 86gt, current owner says the previous owner swapped from the throttle bodg injection it had to multiport, but never got as far as the computer and wiring changes.....

- so im wondering if throttle body was/could have been the stock setup?

- if so, what all would be entailed in that swap?

All 4-cylinder Fieros have throttle body injection. 84-86 have a TBI-300 throttle body, and 87-88 have a TBI-700 throttle body. These are standard GM throttle bodies.

I see.....but thats for 4 cylinders only, all v6's had multiport? so the current owners story of the car originally having throttle body injection doesnt make sense does it?

unless....it is a 4 cylinder and he just doesnt know what he's talking about. could you get a 4 cylinder in a gt? I can see by photos its a gt, but maybe body panels were just swapped

I could get this caf for a grand or little less so hoping I can figure this out, something not making sense to me so so far

V6's all have multi-port. Run the VIN through our club website's vin decoder to see if it was originally a GT or not.

Like Pat said, all Fiero V6's were multiport injection.  Unless you've got another one of those 'the owner thought it was ?? but it was !!' cars.  Being another GT you're looking at, it was originally a multiport injected engine.  It is possible to change out a 4 cylinder throttle body engine and body panels if a 4-cylinder notchback to make a pseudo-GT but the VIN would give it away.
