Throttle body issue

[coreymh]

I have a 1990 laser turbo and i just bought a 63mm tb off of someone. When i went to put it on; i noticed the isc and tps are different? Would i be better off selling it and keeping my stock throttle body or is there a way to get the different accessories to work?

It sounds to me like you got a 91-94 tb, instead of a 90 that has the different sensors.

In my opinion you should just keep your original tb, I've read that the 63mm throttle body gives minimum gain if any.
