could anyone post up a diagram, or at least tell me what pipes go were on the boost pipes(3 port) and the rest of the pipes, as mine are mixed up ...thanks

 

A 98 has a 2 port as OEM, doesn't it? Would appear that a 3-port has been put on as an upgrade?

Anyway:-

3-port connections:


2-port:

 

If I'm right about the 98 having a 2-port as std, then you need to be sure that the 3-port replacement is hooked up properly. So see here:-

IMPORTANT: And if your car has been changed from a 2-port to a 3-port, then a remap is required too!
