Throttle cable Well, like me, many of you will go with a J-Spec motor. The problem is Japanese cars have the throttle exit on the right side of the car, thus the throttle mounts to the right. On A-spec motors, the throttle mounts to the left. You can bring the cable around the front of the motor and mount a bracket that will allow the cable to connect to the right side of the TB. Cost is about $5
Ok, will i need the dash harness from a T2 if i get a haltech?
And whats up w/ the throttle body thing im confused

Yup, no need for changing the harness.

So the haltech also gets rid of the rats nest to ( all the **** under the intake). What about all those vacuum hoses connected to the rats nest, are those all emissions? Could i scrap them right now? I could just run the fuel lines directly to the fuel rails and i already got rid of my egr so what the hell are all those vacuum hoses and solenoids for? I know one solenoid is for the egr what about the other three?
If i switch to a series 5 engine when i get the J-spec, will i still need the airpump to activate the 5th & 6th ports and the VDI if i go w/ haltech?
Will all the radiator hoses and fuel lines match right up with the series 5 J-Spec?

little confused, so right now, without the haltech i can get rid of all that ****?? So i just capp off all the vacuum nozzles, the one on the secondary feul rail, and like 3 on TB and 2 on intake.

Yes, you should be able to get rid of it all if you have an 86-88 motor.

I do have an 88 motor. I asked my local RX-7 mechanic and he said that some of those control high idle speed and cold start. He said that it would probably not run. Has anyone ever done it? Im probably not going to becuz there are no benefits, and once i put it back together i don't want to have to take it apart. But thanks for info

decided to trash it
- I'm going to try and get started on this conversion and was wondering if i could drop a FD fuel pump or some other aftermarket pump in my car right now, as i will need to get one anyway in future for boost. Would that make my 7 run rich? In the future i'm planning on going w/ haltech, but wondering if i could drop in now and save some time. What determines how much fuel gets in anyway? Right now i still have stock 460cc's on there, i don't think putting a bigger fuel pump w/ more pressure would allow and more fuel to get in, right?
Doesn't the injector size determine how much fuel get in? ofcourse assumming u have enough fuel pressure.

An FD fuel pump would do ok, as well as a TII pump. You should be fine with the 460's for now.
