It's just a little turbo

whatever man. 6 jets is just asking for a problem which will gaurantee one cylinder goes lean if there ever is a nozzle issue (which is 6 times more likely than running 1 nozzle).

furthermore i dislike that picture above because there are zapstraps holding key components to the throttle bracket which looks like bad news waiting to happen. likewise with the 6 nozzles all having different length hose between the distributor and individual nozzles. initial delivery is going to be sporadic until full pressure is achieved. and the hoses are not wrapped so boiling and evaporation could occur and make the equal distribution even worse as boost comes on. i hope that your meth starts spraying very early

countless individuals run 1+ nozzles in the charge pipe and it works as intended. optimal 1-nozzle-install will be between the IC outlet and before the throttle plate. the bigger the nozzle you may want to put it slightly further from the throttle plate to give it time to atomize fully.
the goal here should be to cool the whole intake charge and surrounding area to suppress knock and increase octane for added timing.
if your goal is to supplement your fuel with 115 octane methanol then i do understand 6 jets, 1 per cylinder.

if you blow your motor from having 1 nozzle around 6" away (or where we would otherwise agree to be optimal) from the throttle plate then you likely had another issue at the same time.
i would aim your guns more at the tune, or figure out why this/these cylinders were getting less air than the other ones.
with 1 nozzle, if it fucks up you at least have all cylinders still running equal and perhaps your gauges or your ecu can detect the problem.
such probably will not be the case if 1 of your 6 meth nozzles develops an issue.
thats not what i wanna hear when boosting 24-30psi on pump gas.

for example if more air is reaching the #6 cylinder than the other 5 or whatever combo you dream up then methanol or no methanol you still have more air going to cyl #6..... so if this is the case and nissan released the car with uneven air distribution. then you should address that issue perhaps before ever boosting beyond stock levels.
same thing could easily happen with no methanol injection when you tune near the edge.

i would venture a guess that if lee's car has survived this long, with no signs of detonation or knock (he has a knock meter). then he will continue to boost within the safety margin if he gets his car tuned by a true expert.

you can argue with me all you wish. and i will appreciate facts, not opinion. im not a meth injection wizard. i just read alot. if you argue without facts im going to have to take your opinion with a grain of salt along with the other random dudes off the street that ask me why im running 1 turbo instead of 2. isnt 2 better?


if you wonder where the F i made all this crap up from, its time to do some reading.
here is a good start:

http://www.supraforums.com/forum/showthread.php?t=550320

read that thread if nothing else.

ill dig up some more if needed but i think that will be a good start. running meth injection isnt some new sliced bread. its been around quite some time now.

and dont get me wrong i will agree that 6 nozzles could be optimal. but i hope your meth system inspection is a very frequent task.

keep it simple on a street car. less complexity is less chance of something going horribly wrong.
also this post is a tad longer than i intended and i dont care to proof read it so hopefully it makes some kind of sense.

[edit] just so were clear, if your choosing between 1 or 2/3 nozzles pre TB, or direct port. i suggest you research the subject to the max and develop your own preference.
personally i would never do it to my street car but i probably would for a competition car that gets dissassembled often with strict maintenance.

Yes 6 jets is safer for sure but i've Know at least 5 rb26 with a single jet mounted where you have it "leeaspin" and no problems so far .

thank you sir!

So lets say you put them under the manifold. Then you change turbos and need larger jets? Ill let you reconsider you thoughts now.
O and thats an Aquamist HFS-6 system http://www.howertonengineering.com/Aquamist_hfs6.html

put what under the manifold?


....was on the phone didnt see your last comment about the 6 jets

If I was using meth for 100% reliabilty I would use 6 jets...i'm only adding meth for a safety factor...and seeing as how I have not seen or heard of any issues on an RB with this meth I will stick to my one nozzel for now...If you have legit proof of 1 nozzel harming the motor feel free to post it here....dont be a **** about this debate or leave your comments to yourself please...everybody has their own opinion and im going with the recommended requirements for the kit which is 1

Which charge pipe is that?

I was thinking about mounting it after the intercooler either right before the plenum (upper charge pipe) or the one right after the intercooler.

I have it on the upper charge pipe about 6-8 inches away from the plenum

Holy mess, I would have tapped them from under for a stealthier look, but good idea.

[Speeddm]

OO the water meth debate. One vs 6 injectors. I see Leeaspin clearly doesnt understand how ineffective the RB plenum is. Good luck to you sir. If you would like to do it right for an RB take a look.

I would have trimed the lines a little nicer but thats just me. FIX IT S.D.

better have it on the road when mines on the road in the summer there Lee lol

So I got my AEM water meth kit and finally got it somewhat installed...Have all the wiring done and tank+pump mounted...all I have to do now is put the dash all back together and tuck all the wires going to the trunk and under the dash....heres a few pics of the install....

The kit itself


Charge pipe drilled and tapped


Charge pipe with nozzel attached


Tank + pump mounted and installed


Heat wrapped line going to charge pipe


Meth line running from trunk to charge pipe


Dash coming apart for mounting Controller + LED


Will finish tucking wire and such this weekend...finished photos will come....watch out for pro mountage of the meth LED indicator light

may have to snatch this from ya....is it push or pull type?

i have a OS GIKEN R4C MULTI PLATE CLUTH KIT FOR SALE CURRENTLY IN MY CAR BUT WAY TOO GRIPPY FOR MY CAR I HAVE A DAILY DRIVE THIS CLUTH KIT IS MADE TO HANDLE WAY TOO MUCH POWER !!!

I CANT DRIVE MY CAR in the city its not a daily drive cluth kit its pissing me off (iam at 408 whp) wit 2x gt2860rs i defenitely went all out on my cluth kit for nothing

clutch kit is brand new (not even 4000 km) i have receipt from RHD JAPAN WIT purshace date and everything

cluth kit was 2700 now 2000$ brand new

i let mine go for 1400$ + shipping

here some picture of the baby




wen i receive my kit


picture of how baller it is install on the car from a under view :P


neways 1400$ is 600 less then on RHD japan + u dont have to pay long shipping + bording fees

[leeaspin]

well if I have problems with 1 meth nozzle I will let everybody know.....but 6 nozzels is obsurd....pretty much just throw 12 injectors in....thanks for the input but I will stick with 1 nozzel
