What is your review of the water/Meth kit? I'm looking into this.

[Ted95]

i havent activated it yet, ive been waiting to buy the progressive controller for the Devils Own kit but i might just install the manual pressure switch for the mean time instead. i want the progressive controller because it allows for better and easier adjustments. there are many guys on the forum that have it installed with there 3s and have had good results with it, Dustin, Manny, Art, off the top of my head. the WRC's came with the water/meth kit installed in the manifold so if it worked for them it will work for the non WRC as well.

it just allows you to run higher boost safely by lowering the temperature int he combustion chamber by some 250* and gives you a 10-20% hp increase, thats what the specs say on the site, and i think theres a few dynos in the stickies with the meth kit installed on some cars. i think _Jim_ has one posted.

what size of nozzle did you go with ?

I went with a 500 cc or ~ 10 GPH nozzle.

I was lucky, I bought the pump, progressive controler and fittings all for 69 dollars

[Ted95]

well the kit i bought off a member here unused in box came with the D03 and the D07 nozzles, 3GPH and 7GPH, but i wanted to bump up to 10 or 12ish lol.. how does the 10GPH nozzle work?

btw thats a stealll for 69 bucks lol i think i paid 140~

[Culpable04]

I haven't install it, because I'm waiting on my map clamp, unless you are planning to go pass 18 psi, the water injection will just be a bragging rights kind of thing, because the stock ECU and injectors are designed to run 18 psi all day with no issue.

but based on my calculations ( long ago lol ) 10 GPH is the optimum nozzle for 25 psi and 375 hp on a single nozzle setup for our engine / fuel injector size.

of course, I wont run 25 psi on my WRC turbo, but I'll tune for 21, and I'll be comfortable knowing that I have a 4 psi cushion in case something goes wrong. or if I later upgrade the turbo ( not likely ) I have some room for tuning.

I'm also working on getting my HKS F con running so I can truely get the WI and 21 psi full potential by tuning the fuel properly, but it will be a conservative tuning, with enough room for temperature variations and elevations.

from what I've seen an untune WI system on a celica yields aroung 10 whp, and safer temperatures, once tune I hope I get around 30 whp, but time will tell. none of my tuning will be too aggressive since I daily drive the car ( 90 miles round trip ) I want to keep it as reliable as it is right now, so no ball to the wall tuning to squeeze every single ponnie out of it lol.

this is exactly what im trying to do lol. im running 18psi now with the cutout open, 14-15psi with it closed. im waiting to get my map clamp as well, i want to be able to run 20psi safely with my cutout open. im going to get a mild tune as well, 21 psi would be nice.. this too is my DD so im not trying to go to crazy with it either, but still want to get what i can out of it without upgrading turbos and internals for now..

i thought about doing the dual nozzle setup but not really sure if it would be an over kill as im still running my stock turbo and not looking to upgrade anytime soon.
this was good info and gives me a better idea of how to dial in my setup. im looking to run 12s at the track, thats my goal for this summer.

Wow, this is one of the sickest swap threads I have read. I'm sitting here trying to do schoolwork and got stuck reading this thing through from the very beginning. Great job! The car turned out amazing, the engine bay looks amazing, the engine looks amazing. I'm starting my swap pretty soon (upcoming month) and like you this will be my first swap. This pumped me up more than anything! Got my shell, just searching for the engine at the moment but hoping to find one in the next couple weeks .

P.S I'm way glad everything turned out as you hoped cuz you deserve it, thats some dedication and hard work right there!

[Culpable04]

going dual or quad nozzle is actually better. more reliable as you can aim each nozzle to a particular cylinder which would help ensure each cylinder gets a consistent amount of W/A mix, with a single nozzle you have to be more conservative on the tuning as there will be fluctuations on the amount of mist each cylinder will get depending on the location of the nozzle, spray pattern etc.

my nozzle is at the factory location ( WRC ) because I was being a fan boy at the time and did it " just like toyota " by the time I understood what the optimum setup was, the engine was dropped in and I didn't wanna take the manifold out to drill, tap, and install 4 nozzles. but if the engine comes out again, I may take the time to do that.

is your turbo WRC ? or a regular ceramic one ? if so, 20 psi daily may prove to be too much for hte ceramic fins.

[Ted95]

No mines the stock 3rd gen turbo non WRC. I'm going to install my nozzle(s) half way up the cold side of my IC piping. I wouldn't be boosting to 20psi daily, but I can see where it could cause potential damage to the turbo, but maybe the dual nozzle could be a better option? Im not trying to destroy my engine either lol.

I decided to put the nozzle half way up the piping because it will give the particals time to evaporate making the air more dense and colder. I would like to install it lower truthfully but I'm already running out of line and I'd rather it not go past my cupler in the middle.

Thanks man, everything takes time my dude. Just be patient and get all the things u need first and it will go smooth.

[Ted95]

got some goodies on the wayy, pics will be up when they come in hehe

Awesome thread Cam!

[Ted95]

Thanks Jesse!

[Ted95]

so i got some Hiro rears for the coupe that i picked up off of Jesse a few weeks back. this weekend ill be doing some more suspension work, brakes and rotors, inner and outer tie rods and hoping my rear racing beat rear endlinks come in tomorrow. also started shaving the side markers on the fenders, pics up later this weekend.

now that schools done ill finally be able to spend sometime on the car, im trying to get it back on the road asappppp!!

Dumb question...you don't HAVE to tune for water Meth do you? I'd just like to run 20 Psi safely. Will the stock injectors be enough?

[Ted95]

yes a tune will be needed,

quote from a cobaltss forum..

" .. The devils own kit is great and I have it. However, meth itself does not give you power. It decreases your air intake temperatures as well as changes the octane slightly. This in turns helps suppress detination as well as allowing you to tune more aggressively to get the power gains. Also it reduces the heat soaking that also robs power. "

it answered my question about it too lol but the meth doesnt actually cool the temperatures, it adds water to a mixture reducing the overall temperatures

[SupraKid]

meth=moar boost

[bsamps4]

What are you tuning with Cam? Or are you just adjusting the water meth controller, and your boost controller, and letting the ecu take care of the fueling?

[Ted95]

probably a safc2 .. i havent picked one up yet, but its on my check list, need tires first.
