Hi all I've searched and learnt a lot from this forum! So thank you guys that share your knowledge. I'm about to start my AI journey and wanted to know your opinions on the subject.

Well I have a bone stock JDM FD and I'm looking at injecting water or methanol or mix of both to reduce heat soak and all the other advantages they bring. Tuning the car for it is not an option.

What kit would you guys suggest? Preferably the kit will have some room for improvement down the line just in case I decide to tune the car or go single for instance. Also kit has to be easy to install since I will be doing everything myself.

With the amount of kits on the market I'm finding hard to choose. Pls help me make a great choice.

Henri,

the nice thing about 09 is that there are alot of choices compared to 5 years ago.

obviously that presents it's own challenges but...

my first comment is that your probably won't go wrong picking any of the primary kits.

that said, i think alot of the decision should be based on what you do w your car.

if you drag race or just aggressive street drive any of the kits will work fine

if you actually track (road race/circuit) your car there are advantages to the "HD" kit.

Aquamist (UK) and CoolingMist have always been very supportive to this board and both offer excellent products.

non-HD kits that come to mind are:

AEM
Alkycontrol
Aquamist
CoolingMist
Devil'sOwn

HD
Aquamist
CoolingMist
FJO

i have personally used Alkycontrol and FJO and love both. i am currently envolved with the installation and testing of two CoolingMist kits and will be reporting in.

if you care to post more info about your car usage i am sure you will get some addtional help.

good luck,

howard

 

Thanks Howard. Your help is always appreciated.

About the usage of my car. Well its driven on the street + road race/circuit/hill climbs and drag racing. So I'm guessing the HD would be a better bet. Coolingmist seem to offer the most complete kit including tank and all.

Maybe someone from coolingmist will be nice enough to suggest what kit would suite my needs best.

For a stock fd that isn't going to be tuned you should go with straight water. Really for your needs currently, a simple kit would work just fine and be easier to install and setup. Later with a single turbo a more elaborate hd kit would be nice. They are considerably more expensive so you have to weigh out the advantage of already having it for later vs the cost and increased complexity of doing it now. Plus by the time you have the mods to warrant the hd system, they might have come down in cost, or come out with even better systems. Personally i built my own pre turbo wi thats mechanically driven by boost pressure, i like this setup because its effective and simple with little fear of anything failing.

 

Hey Dudemaaanownsanrx7. Thanks for sharing your ideas and helping me out. I'd be very interested in how you setup your system and maybe some pics...

Coolingmist have a kit on clearance at the moment.

Is this good for my needs? Will it be easy to install?

I have thread titled going to build my own wi kit, you can find it by searching. I would post the link, but i'm using my phone right now and it's difficult to copy and paste links. I'll post the link when i'm on a computer.

 

Found it. Very interesting setup you got there. Only thing is that I'm not going single any time soon so its easier to position the nozzle in the intake elbow. Anyways i subscribed to your thread. Keep up the good work mate and thanks for your help.

 

Thanks. Yeah twin turbos would either need 2 nozzles, or an intake box where both turbo's draw from and one nozzle mounted in the box. I think it's doable though

 

I went with two 250cc nozzles one for each turbo, 150 psi pump and dual solenoids. First injector will come on with a pressure switch at 10psi and the second injector will come on using current from the sequential system when the secondary turbo comes online. I should have mine installed in the next week or so. I will snap pics as I install it.

 

Sounds awesome look forward to hearing how it works for you

 

That's great. Pics would be great...

 

I'm also interested in an AI setup. My current build is a full bolt-on FD with 15psi on non-seq. Turbos, and eventually a gt35r. I'm building the car to drag, no circuits. Will any basic kit work for me as well or do I need a little more? Intercooler is a GReddy SMIC btw.

Thanks in advance,
Jim

 

Hello,

I am just suscribing to the thread. I have a stock(ish) FD and I am interested in water AI too (and I'd have the same use than Mad^94rx7 too).

I don't want to be thread jacking (let me know if I do) but since I don't want to change the ECU I am guessing stock settings won't be optimum then (especially timings), and I was wondering if anyone had any ideas on the power/torque loss?

Joel

 

Hi Joel

you ain't thread jacking mate... actually I'd like to hear what the experts have to say about your questions...

 

My install is nearly complete. I ran into a few issues towards the end of the install and ran out of time to complete it (Zoom Fest & PDX @ Road Atlanta), so the last of the pics taken aren't as detailed as the first ones. I still have to make a box for the solenoids, connect the remainder of the hose and rewire the trigger from the sequential system. It may be next weekend before I can work on it again but if I have some free time, I may post my progress to where I'm at now.

 

Great take your time mate and hope it works out great for you.

 

My AI install... progress so far. https://www.rx7club.com/forum/showthread.php?t=853770

 

If you don't push too much water (you won't need much with a stock car) and make sure the water is well atomized, (preturbo works great at atomizing) you shouldn't lose any power, an ignition amp such as a twin power would help if you did lose some. The problem with the stock ecu is it runs so rich that adding water could make the mixture more difficult to burn. A better spark will help ignite everything in there.
