What throttle body do i need?

[FASTSPOOLINGST]

I have a 91 GSX i am building, I just want to make sure i will be getting the correct throttle body. Which ones are interchangeable for my vehicle?

90-94 turbo only (are AWD and FWD different), etc????

will n/t 1g tb's fit?

what vaccum nipples do i need?

please post pics of the correct one i need if u have them.

Thanks in advance.

1G Throttle Body
Must be from a June '90 thru 94 car ('91-94 model year). The correct one has 4 vacuum connections on the top of the TB facing towards the passenger side of the car. The earlier '89-May'90 TB has two fittings on the top and two on the front side, this one will not work.

turbo/non-turbo, does that matter, or are they the same for those years?

there are so many people on ebay selling n/t tb's stating they will work on a 1g turbo car and they are non turbo tb's. I hope people are aware of this before buying.

I was just wondering if someone that doesnt have there emmissions stuff on and all those extra vaccums hose and will just have the four ports capped. if they could still use the 90 throttle body or does it still need to be the 91-94?
