Saw this, and thought of this thread.

 

So i found a fit ment issue with the twin. It happens to be the water pump inlet. On the fb it comes in on the side. On the FD it comes in from the front veritcally. The inlet on the FB is in the way of the Primary turbo Inlet. I dont think i can modify this to make it work

 

The second set of pictures show a similar problem, it looks like they didn't have too much of a clearance issue. I know its not an FB, but you might be able to just use a heat shield to make up for how close the hose will be to the inlet.

Edit-

The first set of pictures also shows a work around using a steel braided radiator hose. Though I would think that using a smaller diameter hose would increase temperatures slightly because the pressure remains constant and the size of the tube is smaller thus reducing the volume of liquid being moved at once. Though I have been known to over think things.

You will see the inlet on the left. That is too close to the Turbo inlet. It will prevent me from puttin on the Inlet tube for the turbo. And the Y pipe will not clear the stock manifold and or the Racing Beat manifold i got

 

use a different water pump housing or cut and fab....

 

I know i can use a FC housing with some mods. But can i use a FD? Ill look at a FC housing and see what i can do. This is def going a little slower than i thought but its going. I got a RB holly stock port manifold. Gonna get a adapter mad to adapt the nikki to it for now. And look at a 4 injector TB. Someone got one from PR so ill see what i can find. Id love to fuel injection on it along with the turbos. Then i can possibly got fuel electronic twin setup with computer controlled timming. I think if i can get it that far she will be a sweet ride. Oh i also found someone that will sell his aggresive street port 12A for 200 bucks. Hes moving to new york and he dosnt have a 7 anymore nor any room to store all the parts he has. So i may get lucky and with the twin setup and FI get the power of the FD in a FB on a smaller motor We shall see.

 

go with a single bigger turbo .more simple

 

put the intake on, and then see if the turbos fit...

 

I had to read this several times to understand what you meant.
Is English your primary language?

 

It is. Sorry about that. I was in a rush to get it typed up. Ill try to slow down and make it clear.

 

Alright Time for a update. Been a lill while. Haven’t really gotten any closer to actually putting the Twins on yet. Im stepping away from going carb and going fuel injection. I am gonna use the RB intake with a throttle body with 4 injectors. I’m using a MegaSquirt 2 ECU with FC leading and trailing coils. I’m also gonna look into how to control the SEQ twins with the MSII. Most likely that’s gonna be a long process to do. Im also trying to pick up a FD water pump housing and see how its gonna fit.
I was able to pick up housings and side housings also. I need some help in that department. The housing I was told are shot. The exhaust port is too big. I was told they are ported to far up. Maybe too much overlap? IDK. I need to pick them up and take better pics with measurements to see what others think. The side housings are street ported so that would help in HP department.
Anyway. This is still ongoing. I do hope to have this done soon. But time and money are against me right now. I need to move to a new place in FEB or March. And i need one with a Garage. Till im able to get another car i can only do so much to mine. It is my DD.

 

What a Shock!!

 

All kidding aside.

This is your DD. Don't **** with it until you have a new DD.

And then, you are not an engineer. Stop trying to make the wheel
again. It's been done, and done well. Swap a straight TII unit in place,
save alot of money, time, and headaches - and enjoy your car.

In this case, it's NOT the Journey (Building it) - it's the Destination. (Having a running car)

 

True true. But im doing this because i want to. I want to be different. Ill slowly work on it. Even as its my DD. I saw ur vid of ur GSL-SE. ****** sweet. I may not be a engineer but i work on electronics for my job. and work on cars at home. Mainly mine. This will continue until i poke my eye out

 

arghx Hope ur still watching this thread but I have thought of another way to help out with controlling the Twin on a FB. Im gonna be using a MSII. And now that they have the Boost controller upgrade kit. Can I incorporate that into the system that you have outlined. And im also think that now that i have the zeal daughter kit installed on the MSII i can you switched outputs to control the solenoids instead of the RPM activated switch. Just some food for thought. Im in the process of cleaning up the Turbos now and Fuel injecting the car. So no need to worry about me using the Nikki as I first laid out.

 

i don't know anything about the MS, but it should be able to do an RPM switch or 2.

one of our drivers was showing this analog to digital controller thing too, and that would also work. its a little box, and you hook up what ever you want, and there is a series of drop down menus and you just pick what you want. its not fast/accurate enough to do spark/fuel control, but i see no reason why it can't do anything else, including the twins, or the OBD stuff.

i'll have to ask who makes it, google just gives me PS2 controllers?!?!

 

The MS can do like 12 extra switch. Can be based on any perameter you want. Temp, Throttle POS, RPM, Speed. You name it. And analog to digital thing sounds sweet

 

I'm amazed that this thread has gone on for 5 pages.....

Only question I can think of is .... WHY?

 

^ to be super cool and go down in rx7 history!

 

Exactly. To go down in RX7 history as the first to try and fail...Maybe. But i will try and it will be documented as me trying.

 

got twins on an fc block with an fc turbo INTAKE manifold, with custom, "wedge"spacers, i plan to run them sequ. and do a full write up after.. the engine gets rebuilt, the oil/cool/intake lines are sorted and can actually drive the car, i don't feel like showing someone how to get half way and them getting the other half before i can. i want to be first(fc block with fd twins that is)

 

Nice. I really dont care if someone else trys this. There is a lot of work to be done to do this on a 12A so im sure someone would pretty much say F@#$ it and leave it be.
