which throttle body?

[szewczyd]

I have a 97 GSX with a six bolt swap that I recently purchased and it has no cold start feature. The guy I bought the car from said that he removed the bottom half of the throttle body and just blocked it cause the sensor was going and causing irratic idle. I want to get a hole new one and wondering what year I need so I can just plug it in and bolt it up? Thanks Doug

P.S here is the thread where the previous owner talks about removing it.

The sensors on the 1990 engine were different from the 91+. You just have to pick which one is appropriate for you.

Either a 1G ('91-'94) or 2G will bolt up fine, assuming the 6 bolt is a '91-'92. If you want the exact one that's already on there, post up a picture and someone can tell you whether its a 1G or 2G.

If you don't have a camera. 2G's have 3 vacuum nipples facing the drivers side of the car. 1G's have 4 nipples facing the passenger side one of which is at a 45* angle towards the firewall.

Doug,

If you want a whole new throttle body then look for a late model 1G TB. Any from a 91-94 Turbo car should be fine. If the swap used 90 style parts you don't want to keep them.

I have a local guy that has one from a 93 with all sensors and says it works perfect. Will that plug right in for me?

It depends on how the TPS and IPS were wires in the swap. I like using the 2G TPS soi that you don't have to change the wiring or adjustmen procedure of the IPS.
That leaves the 1G IPS acting only as the throttle stop screw. If your IPS is wired up then you can use the 93 TB and sensors out of the box. Otherwise you'll need to swap the 2G TPS over to the TB.
