Boost controller? FCD??? whats the deal with safe exhaust upgrade...
Hi guys, im new both to the forums and also rotary's. I just purchased a 1987 rx7 TII and im getting the RB complete dual exhaust(DP,presilencer,y-pipe, and mufflers). I have searched and read multiple posts but none have answered my question. If i have an HKS manual boost controller in my car and i set it to low boost do i still need to purchase and FCD? or can i run safely without one? From what i understand, if i get the RB complete exhaust i have to: 1) port waste gate,2) buy an Rtek or FCD. like i said, i have searched these forums many times and im sorry if i missed what i am looking for - send me a link or share your knowledge with a noob. I also have an HKS intake! its an awsome car i hope to see you local guys around, i have seen some at the 99 ranch meet in artesia ca on monday nights! p.s. - i hear a FCD is harmful?...so i kinda dont want to go that route but what do you guys think?
this is not a daily driver, its a project car that i am aiming to get around 250whp safely......FOR NOW AT LEAST .
THANKS

not an after market, just the stock one. it still works fine but im not sure about accuracy. i keep the boost controller on low all the time and it goes 1/2 way up on wide open throttle which is ~ 5 psi (on low) i believe, medium setting took it all the way up to 40 on the stock gauge which is ~ 7 or so psi. (this is all according to my handy pressure conversion calculator http://www.online-ambulance.com/calc...Conversion.htm)

Yeah a boost controller won't help you, as stated above it can only raise your boost, not lower it, a fcd and a heavily ported wastegate should keep you safe, just make sure you have an accurate boost gauge to keep an eye on things.
