Default Injecting a single turbo rotary...HELP please

I'm new to this forum as well as WI, but I have been doing a lot of research and I think i've finally made up my mind on going with Devil's own.

I know I'm going with the universal stage 2 kit and I plan to run a 50/50 mix. But I have a few questions...

1. Is the outside nozzel any better than the inside mount?
2. I still don't know what size jets i will need or how many (1 or 2)
3. what size tank i'll need to last a whole tank of gas.

Here is my setup,hopefully it will help to better answer my questions.

1/2 bridge REW
Garrett GT3574
only have 91 octane in my area and would like to run up to ~20psi give or take...
I will be using the 3 bar controller
And my FD has a 20 gal gas tank. I know that's pretty big for such a smalll car but I am running 2 850cc and 2 1600cc injectors, and on a half bridge motor 20 gal won't go too far lol.

All comments, tips, and advise are welcome.

Thanx in advance
Cyan

The piping for my FMIC seems kinda thin, so I'm thinking i'll need the inside mounting nozzles...

Oh and at what pioint is the pump upgrade recommended?

Have you checked out

Auxiliary Injection - RX7Club.com

Should give you some good vehicle relevant info.

1. If you have a way to mount the outside nozzle, it will take up less room. A little extra material on your piping and a 1/8 tap and you can mount the nozzle.

2. Go here

http://www.alcohol-injection.com/for...lator-351.html

3. How much boost, and what kit, and what nozzles, and all sorts of other stuff. Your stock tank windshield wiper fluid tank should do ok for you for now.

Upgraded pump is for those flowing ALOT of fluid, like full blown race cars, and TD pullers.

I have looked through the 7club but there really isn't much feed back from rotary ownersusing Devil's own. I'll make a thread over there about which nozzle size I need.

I didn't even think about adding matirial to the intercooler piping, thanx for the tip

You can search for bungs is what they are called, or if you know a shop with a welder and a 1/8 tap, you have the same thing.

Be careful with a rotary....

They use oil injection and excess fuel to help lubricate the rotors. If you wash the rotor housings down with to much alcohol/meth it will wear your engine ALOT faster. 50/50 mix you should be alright, but try to use the smallest amount possible. Just enough to control detonation. (Devils own alcohol nozzle calculator works well for this.)

I personally trim my WOT fuel settings way back and use alot of 100% methanol to so I can run huge boost and timing.

Your limited with the rotary.... Sweet car BTW... ;)
