My buddy picked up an fd that is in need of some tlc. When he got it, the car was generating no boost. After talking to me, I told him he could either try and redo all the vacuum hoses, or go non-sequential and eliminate all the bs. I helped him do the "poor man's" non-sequential mod. Afterwe got it all abck together, there is still no boost. The car is definately louder from full exhaust flow all the time, but themost boost I saw was .02 on the pfc. When he gets on it I can kind of hear the turbos whinning, but they aren't doing anything. We tried using the ore-control solnoid instead to see if it changed anything, but nothing. Feels like te wastegate is just stuck open. Sequential operation is selected of on the pfc and I even tried jacking the duty cycle up with no change. I told him his bestbet was to make sure he has all the hoses right, and if not that then replace the wastegate control solnoid. If not that, then I would suspect the turbos themselves.

the car has intake, dp, mp, cb, pfc

i just did non seq boy was that a pain https://www.nopistons.com/forums/pub...1047683358.gif https://www.nopistons.com/forums/pub...1047683358.gif thought you wired 1 WG open then got 5 psi above 4,500 then tired to get the WG rod back on the Flapper and wouldnt go on that took me 2 days and now im finaly done and about to go for a ride but i hope i get boost.



id say make sure all your lines are plugged and make sure everything is right.

leak in the intake plumbing?



speed/density so it will still run with vac leaks, but boost won't build with a leak big enough.

really dumb question, is the map sensor hooked to the right place? with a dp cb, and mp it should be at like 15psi no problem

I don't hear any boost leaks. That was my first thought. I'm pretty familiar with the rx-7 turbo system, its just been while since I had the twins.

I agree, your problem is in the wastegate solonoid or the actuator itself. Make sure that the actuator rod isn't stuck. https://www.nopistons.com/forums/pub...IR#>/boink.gif There is nothing else involving boost control or any leak points. Im assuming that you cheaked the "y" pipe couplers for breaks/blown off etc...?



Bastard "Oh I havent had the twins in a while" Bite me single turbo boy https://www.nopistons.com/forums/pub...1047683785.gif https://www.nopistons.com/forums/pub...IR#>/bigok.gif
