wasnt there a company that was making some kind of electronic gizmo that opened the ports up at certain rpm?
And how do series 5 owners remove air pump etc if this opens the ports p.s i cant just wire dem open cos its a auto and i need what little torque there is to offer |
Try this site it has some info on getting around the six port actuation... http://homepage.mac.com/jburger/jaysrx7/6PortSolution/
It says it is for 86 - 88 rx7s I don't know for sure if it'll work on a 89 - 91 https://www.nopistons.com/forums/pub...#>/BURNOUT.gif |
I used the air pump on my 87 n/a engine. Went to home depot got a water hose spliter vavle (and some misc items to make the hoses fit) and adjusted the vavle to give enough pressure to open the ports after 4k.
Most of cost like 5 bucks for everything. C |

U only really want to do that if u had no Backpressure, and no airpump = straighpipes. https://www.nopistons.com/forums/pub...1047683785.gif

Listen to that, back pressure, you guys really want back pressure? Back pressure kills your power on the mid to top end. I Had no back pressure and I didn't run headers.
