Restrictor goes between the turbo nipple and the T-piece if you are still running a 2-port.
But I expect yours may of been converted to a 3-port boost solenoid and hence the plumbing is different and doesn't require the restrictor. Standard 2-port plumbing : turbo to T-piece (restrctor in pipe) T-piece to Actuator Bottom branch or T-piece to Boost Control Solenoid Then Boost conrol solenoid to inlet manifold (the little black elbow just to left of main induction hose). 3-port plumbing : turbo to Boost control solenoid (top port if OE 93-96 style solenoid) Middle Boost Control Solenoid to Actuator Bottom Boost Control Solenoid to inlet manifold (the little black elbow just to left of main induction hose). re : headers, ported OE should work. It may improve midrange torque but loose a little top end. |

A set of my ported headers have seen over 400bhp . not sure on spool up might be able to get a gragh if he still has it .
what size is your up pipe? maybe go smaller?
