ok heres the thing. i cant get any boost, i noe i have a vac leak but not sure how how vac leak i have. also it backfires like crazy, could it be that i'm running too rich, i can smell the fuel while i drive while the window is open. also it backfires loud after i get alittle boost around 2-3 psi, sounds like a gun. any help guys?

 

well first off, its pretty damn hard to fix a problem when you have an existing vac leak so i would suggest fixing that first. secondly, its a lot easier to help when we know what you are asking, its a little hard to read your post, grammar helps. also, if you can smell fuel that intensly, it may be your pulsation dampener failing, which can easily lead to fires (squirting raw fuel and such), so you may want to check on that while you are looking for vac leaks. as far as your problem, it could be your twin scroll solenoid is failing or vac line is disconnected which could be the source of both vac leak and lack of boost, but at this point it is just speculation. as i dont know anything other than you have a vac leak and no boost. what year is it? what mods? any prior issues?

note: if you have an s5, ignore what i said about the twin scroll.

 

lol sorry about the bad thread. well i just brought the car so i have no idea what were the prior problems of the car but, the thing is that this is my first rx7, dont know anything much about it. it is a 90' gtu with i believe has a 91 t2 swap, it has a safc2 and rb fcd, and dp and 3' pipes all the way to the muffler. and a blow off valve. hey "well uhhh" can you tell me what is the pulsation dampener? and where is it? so i can replace it. thanks.

 

the PD is on the end of your primary fuel rail. just use the search button, the pd topic has been beaten to death. I would suggest just reading as much as possible about your 7. FAQ and Archives are a great way to start. there is also a free pdf version of the Factory service manual in the FAQ's

 

thanks well uhh. one other thing do you know how to remove the warm up thing. just dont like the motor to be rev up that high in the morning.
