Guest Anonymous Posted April 7, 2003 Share Posted April 7, 2003 How do you increse the boost on a stock 280zx? Do you completely remove the pop-off valve? Or is a boost controller in order. I can make one right? Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted April 7, 2003 Share Posted April 7, 2003 You could thread the rod on the wastegate actuator. That will allow you to change the tension on the diaphram, or use a bleeder valve, or do a ball/spring type valve. Any of these you can do yourself. If you only want to turn up the boost a few lbs, then I would go with threading the wastegate rod or using the wastegate from an 8_-89 300zx turbo as I believe they were already threaded. When you do start turning up the boost, do it slowly so your pistons and rings don't go BOOM! Quote Link to comment Share on other sites More sharing options...
