How do you run the s4 oil pump with s5 TB
I got a question for you guys, I recently switched over to haltech and am using the s5 tps and TB. I currently have the oil pump stick ziptied all the way open and its causing me to smoke like crazy at idle.. is there a correct way to have iit installed? are there any downsides to having the oil pump pumping on fullblast at all times?

Take the Oil pump off and premix..
If is is S5 on Haltech, it wouldn't really matter,would it?
another Idea,you could use an S4 Throttlle body?..
OR,see if the S4 TB side Piece(the one that holds the Oil linkage to the throttle body) will go on the S5 TB.then you stay as you are setup.But with the Omp hooked to your S5 TB..get me?( I hope so,I am confusing myself!).

Aren't there other little sheaves for pull type cables on the S5 throttle body? (Cables such as automatic transmission kickdown cable, or cruise control)
Fabricate a small angle bracket near the S4 OMP and attach a throttle cable, bicycle brake cable, or lawnmower cable (IE You can get the pull cables anywhere and you have a wide selection based on your routing and length requirements) to the OMP. Attach the other end of the cable to the sheave on the S5 throttle body. Use a spring to return the OMP to idle position when you release the throttle.
Cost:
Angle bracket
Cable
Spring
(Couple bucks a piece)
This brings up a few questions of mine:
1.) Does the S5 TB flow more air than the S4? Does the S5 TB have any benefit over the S4?
2.) Is the S4 and S5 TPS any different?
-I am aware that the S5 has two plungers and the S4 has one. I was under the impression that one of the plungers on the S4 was identical to the S4 and the second plunger on the S5 was to actuate the electronic OMP.

one of the reasons why people who use haltech also use the s5 tb is because of the TPS sensors..
so you're saying run a cable off of the omp and attach it to the s5 tb?

I went through that with my throttle body, the S5 throttle body does not give you alot of room for a cable set up.
My engine builder uses a cable set up on his FD set up, on those throttle bodies there is more room.
A much easier solution is to just use a s4 throttle body, I dont think there is any performance gain using a S5 versus a S4.

If money is preventing you from fixing this correctly, then why don't you just premix for now until you can afford to do something different? Just cut that ziptie you have on the MOP and add 1oz of TCW3 2-cycle oil per gallon of gas. I'm not sure what "full flow" on the oil injectors amounts to, but that is your crankcase oil getting pumped in to the motor at full speed. Check your oil often if you keep this bad idea up....
I have never seen, or specifically heard of someone who put an S5 Turbo TPS onto an S4 throttle body. It would certainly involve some form of custom fabrication. If I were you, I would premix for now and run the S5 TB/ TPS. In the meantime, save some money and get your S4 TB modified to accept the Haltech TPS. I can't imagine a D-shaft mod to a throttle body costing over $50-100. The Haltech TPS is a full range TPS you can buy brand new for around $45, compared to a new S5 Turbo TPS at about $280.
If you can't afford $100 for machining and the Haltech TPS to properly fix this, I might suggest selling your RX-7. No offense, I'm just saying it's not the best vehicle for those on a shoestring budget.

That's what I used to do when I ran gasoline. All the searching I ever did resulted in me deciding the most common range for street car premixing is 128:1 to 100:1, which is 1 to 1 1/8oz per gallon. The only time my exhaust ever smelled different was when I added a little extra 2-cycle the one time I took my car to an autocross.
On the other hand, I think Viking War Hammer ran no MOP and no premix in his 600hp FD for a few years, so I'm not claiming to be an expert

Like pele mentioned, you can run a bicycle cable and rig it to operate.
Sounds like you are being stubborn
You have many low cost options to get things running.
