Is it possible to remove all the vacuum lines.
 

"The sequential twin turbo system has frequent problems because it uses hundreds of feet of vacuum lines and many solenoids to control when each turbo comes on line. The turbos can be converted to a parallel set up, meaning they operate at the same time creating slightly more lag but increased top end power. By removing almost all of the vacuum line and solenoids all the boost issues are taken care of for next to no money. With these two problems addressed the RX-7 becomes a respectable car in terms of reliability. "

I read this some where and was just in :eek: on how removing all the vacuum lines and solenoids could be possible and at that costing next to nothing :eek:.

you dont remove all the vacuum lines. but yeah you can make the FD non-sequential turbo,(they both come on at the same time) but with this comes later boost around 3500RPM i believe. as appose to the sequential whcih one turbo(primary)comes online first followed the the 2nd turbo(secondary)

Well yes you can but it'll run like shit... :D
(no map sensor and no wastegate :eek:)
If you're going non seq. and you're removing the emissions garbage as well, you can get away with 95% fewer lines, what you'll need in terms of vaccuum lines that comes to mind, are Boost Gauge, BOV, Map Sensor, and wastegate ....

I see okay so that only applies to the non-sequential setup. The way it is worded made me think it was applicable to the sequential as well.

just to drop some info here bout your quote....theres not hundreds of feet of vacuum line...more like 40ft-50ft....and about 70 +or- 10 or so lines....
