You don't. A manual boost controller (actually, all boost controllers) should have the shortest amount of tubing possible. This means mounting it on the driver side strut tower. Anything farther away is potential for boost leaks, spiking, and other problems.I am installing a Manual Boost Control into my 1984 300zx. I want to know where the best place would be to feed the tube through the firewall, or would i have to do some drilling (which i dont want to do). thank you
Then buy an electronic boost controller.yeah i understand how the manual boost control isnt suppose to go inside the car but i wanted to make it go in and sit under my dash. I am pretty lazy and i thought it would be better if i could change the boost without getting out
