i took off a lot of the emission vacuum lines off and right now i think im only 3 to 5 vac. lines....can i take off the charcoal canister as well?

and i also just did a non-turbo to turbo engine swap...on the turbo housing i think its the knock sensor ( right above the spark plug) should i wire that up or can i leave it unplugged...my power fc has a knock reading but i dont know whats it for....any hints?

 

You can take off the charcoal canister, but you then need to run a catch can from the nipple near the oil fill tube to the catch can. AND the catch can must be vented. this is for crankcase ventilation, and the catch-can is to collect the oil that comes with the ventilation.

The knock sensor I am not so sure about...a good tuner probably won't need the knock sensor...but it may save your motor one day.

 

on the catch can...does it go the nipple on the fiiler tube to the can..from the can to the nipple that was hooked up to the charcoal canister....and it must be vented...correct

 

correct

 

thanx man...and on the knock sensor...when i get done with the build im takin it to aspec up in chicago so hopefully they can help me out with that..

 

are you talking about a chacoal canister? The one with the metal check valve that is used to vent the fuel vapor. Or something else?

 

its on the passenger side near the firewall...it vents fuel vapor and and theres a nipple coming off the block just under the oil fill tube....i guess when u hook up a catch can...u can also run the fuel vapor line to that to...just so u wont get the smell of vapors...

 

im buildin a rx7 and i put a jacobs fc1000 igintion on and now when the car idles..it will surge...the rpm gauge will bounce...from abt 1500rmps to abt 2000rpms...i havent had the car tuned yet but just makin sure when i take it to aspec tuning...that they can fix...or if anyones know how u can tell me some tips on how to correct this problem...

 

hey does the charcoal canister need to be connected mine doesnt have one at all and my knock sensor is srewd into where the oil catch tank line should go there is no nipple on either side just a bolt on the other side and is my knock sensor thing ment to go above the spark plugs on the 1# rotor housing correct , i got a 86 rx7 s4 with s5 turbo engine and gearbox my mate roughly put it together after it got stolen but did it wrong now i gota go thru everything , if anyone can help me out please contact me , any diagrams of the engine, engine parts, vacume lines and the wiring would be awesome
