Message	if you are going to run a larger throttle body that uses the same bolt pattern, then there is no issue with porting it out to 58mm or 60mm If you are using a 240sx throttle body, then you don't know for sure where the centerline of the throttle body will be in relation to the throttle body flange. I don't recommend the 240sx throttle body considering the manifold rework required. Just buy the 58mm throttle bodies and be done with it. The latest Z1 throttle bodies are actually pretty nice
