Ok you can flame me later, but I like to have straight forward answers.

I am going single turbo with emissions removed. Now from my understanding I can just remove the solenoids as well. I am already following the workshop on how to convert my wiring harness, but want to be sure on the solenoids.

I know I am removing the ACV, Airpump, stock turbo's duh, using and aftermarket FPR with the new fuels sytems, and EGR,

Is there anything on the solenoid I have to leave? ECU is a PFC

Thanks guys.

I'm usually not the guy to post this, but did you search? This has been covered before, believe it or not

you dont need the wire harness anymore. when you go single turbo you can also remove your steering wheel gaskets.

Wow you are an unbelievable ****. Yes I did search. I know that I can delete the AWS, EGR, Turbo control etc for the solenoids that are not in use. My question was are there any solenoids that MUST be left if so which ones. Most of the links are dead believe it or not. But way to be a dick.

Agreed.... if you're not going to contribute,... move along.

+1 on searching... Search single harness in the FD section & Single Turbo section. You'll find many threads & pics of what people have done. Took 5 seconds dude....

Questions beyond these threads are welcome though

As far as solenoids you must keep?.... there are none. The PFC is very resilient. I ditched pretty much everything when I went single, including the OMP. I de-pinned every wire back to the ECU plug and my car runs flawlessly.

The KEY is watching the grounds. If you keep particular plugs make sure that the plug or sensor retains its ground back to the ECU or to the two grounding points on the block. Ground wires are black.

Only "plugs" I kept on Emissions harness:

TPS (backside TB)
Air temp sensor (underside UIM)
Injectors
Water temp (t-stat housing)
Water sensor (t-stat housing)
Coolant level (t-stat housing)
Crank Angle Leading & Trailing
Coolant disconnect (connects to body engine harness)
Knock sensor (above front rotor spark plugs)
Coolant sender (rear rotor housing below oil pedestal)
Transmission disconnects (routed back to tranny)

If you are keeping the A/C, most recommend keeping the IAC as it helps your idle with accessory load.

XLR8- Thank bro. i actually did find those threads earlier. I am just real hesitant when it comes to removing things. I think between double checking those threads again and Triple R rotary I am good. As far as i can tell since I am going single with no AWS, Air Pump, EGR, Double throttle, and an aftermarket fuel system I am pretty safe to remove all of them. That is unless I totally overlooked something obvious.

both of these have been an increasing problem on the forum. dead links, and *** holes.

Nope, you should be good to go.

Reread my post.... I edited a few things to try to explain more. Any questions through the process, just PM me. I got intimate with that harness when I did mine.

I will add if you are thinking of using the common top feed injectors & resistors..... DON"T

Purchase a sweet little unit called an "FJO Injector Driver". Do some searching, they are well worth it.

Josh&fd

cant i have a little fun?
If you arent keeping any emmisions, then you dont need any solenoids. The PFC can
run without any as stated above. Sorry if I offended anyone lol.

You don't HAVE to cut up your harness man. You can tape parts of it up or secure things out of the way with zip ties. It won't look as clean but you can still reverse things.

Or get high impedance top feed Injector Dynamics injectors! 725 and 2200 should be more than enough for most setups.

And I totally agree on this one. I would have went this way had I not bought the "Ultimate Fuel System" from Rx7store,.... which I regret.

True.....

If it's an old harness, I would cut it up for the purpose of double checking every plug & the continuity of each wire. I did this to ensure all was well. New harness's are not cheap.... at all.

If it's a newer harness, then you could leave it with option of going back to twins.... Then again, who would ever do that?!?
