Hello,

i am new to the forums. I have been experimenting with different setups on my 03 mazdaspeed turbo for a few years now. I have had every possible external mod on the car, ive had it near stock and everywhere in between lol

With my last setup (14psi, fmic, 3" turboback, WI etc) I detroyed the transmission and LSD in 1 night of fun. Going WOT in 3rd gear going 100KMPH and the tires would light up and chirp 4th lol lots of power and fun. Best stock motor MSP I have ever seen

Rebuilt the trans with a torsen LSD to handle the power better then the first one did and replaced motor due to rod bearing failure from poorly baffled oil pan. (I like the turns lol .91G on skidpad )

I am using (please,please dont ban me I am a good guy LOL) a different brand of WI kit then everyone else on this forum, but it appears to be the same as the basic kit sold here minus the stickers. (though I should point out i did pay more-stupid me, wish I found this site sooner-SERIOUSLY)

During my trials with WI I noticed that the #1 cylinder will never get a proper distribution of fuel from the KIT. I was injecting with 1 nozzle right at the throttlebody and due to the weirdo " C " shape of the IM and its internal working components (VTC, VICS) I dont think the WI mixed properly in the manifold causing high EGTs, cylinder temps, detonation etc from the #1 cylinder.

Now that I have a spare IM to play with, I took a shitload of brass fittings and made an inexpensive fuel rail and ran a WI line for each port so that the kit is now an INDIVIDUAL port methenol injection system.

here is a pic if you guys wanna fab up your own fuel rails for under $20. Got all the nice fittings.



To finish the project, all I need is 3 more actuators, 4 nozzles and a way to figure out the best distance to have each nozzle from the port on the cylinder head. I am thinking 3-5 inches is the way to go, but I am scared having it so close may disturb the mixing of fuel from the normal injectors.

I am also unsure what size nozzle to be using on the kit. I am looking to keep the stock 230cc fuel injectors in place and then provide fueling via the kit for an additional 100-200WHP worth of fuel over the stock 230CCs.

Stock injectors are maxed at 10psi, 5500RPM. 12psi ~4000-4500RPM etc. So From what I have see roughly 190-220WHP.

I am looking to boost 16psi in the near future with the stock T25R BB turbo, maybe 22 or so when I upgrade the exhaust side with components from a T28 and port the housings nicely.

Wondering if anyone has some advice for my setup, particularly what size of nozzles, and whether or not I would be able to pull of a decent tune with the Progressive Controller sold here with my setup, rather then have to go buy YET ANOTHER damn expensive EMS. I removed my FMIC as I am now going for a complete stock sleeper look, so I may need a bit larger nozzles to help cool the charge. My current nozzle from my old setup is apparently good for motor running up to 250WHP. I am unsure of the actually flowrate. Any help on sizing and reccomended mixture to run would be great.

Also, the Progressive Controller says it can work off voltages, so it would work fine with my 0-5V MAF? What happens when the MAF gets maxed? I have a device preventing this that keeps the voltage at 4.8-4.9 during WOT to prevent hitting fuel cut. I am guessing I would just lean out after this as the controller would no longer be increasing the pressure since the voltage stops increasing.
Could I just hook up a MAP sensor to my IM and have it run nothing but the Progressive Controller since I NEED to have a MAF on stock ECU.

Sorry for all the ramblings and what not, hope someone here can give me some real world advise.

Thanks for your time, Jeff

here are some pics of my olds setups, dont mind the glue in the first pic, it wa an extra precaution that I only had on for the initial testing lol



This pic shows how small the stock IC is compared to my old FMIC. I am going with the stocker now though as I wanna be "stock appearing" lol

thanks for any help you guys may have-Jeff

Here is a picture of the layout of the system. As you can see I still need 3 solenoids and 4 new nozzles.

[Rocket468]

Not sure why you need all the solenoids. You should only need 1 to pressurize the system. As for nozzle sizes. In your setup I would start off with .75 nozzles, I don't stock them but can get them.

Yea, there are some intakes that do have bad distubution. This is when multi port becomes an option. Sometime though moving the nozzle around can help this. Moving it futher down stream or changing its axis.

This is a pretty neat setup you are running.

thanks for the help.

if i do not run an individual solenoid for each line would it not leak all of the liquid in the rail and lines when the solenoid shuts? Wouldnt the VAC from a car suck it right out?

[Rocket468]

You can put a nozzle at the inlet of your rails. Yes, it will bleed the pressure in the rails to the solenoids. You need to keep the solenoids as far away as passable from the engine so the heat cycling does not wear it out.

Would a distribution block be easier and simpler? I think it would be less likely to rob the last hose of fuel.

As a totally off-topic comment, how do you like your MS Protege?

[vtec-this]

they are nice but have their quirks. The stock block cant last long over 250WHP which is a bit of a disappointment, but the handling is top notch. You can drive corners around cars like the ITR even with the stock setup. Stock setup even allows you to adjust -2 degrees in the front. Put less then a grand into the car and you have a mid 13 second 4 door that outhandles any other stock non-supercar. R & T record it at 8th best handling car of all time in MP3 form (so no turbo or LSD). Rest of the list is porsches ferrarris etc. to give you an idea of how it handles. Its on rails lol ranges .89-.92 Gs stock on a skidpad depending on magazine and driver talent.

got the system running, everything seems great, using a very very chate homemade controller I made inside of an old HP small form factor. It works but I really need to upgrade to the one sold here and get the proper sized nozzles. I am running 50/50 meth water and need to figure out what kind of heat range of spark plug I should be running now.

is Rocket468 the guy i should be messaging about buying this stuff? Sorta want to talk to someone about the details whether online or over the phone before I buy.
