NITROUS OXIDE ( nos / n2o ) advice forum

basically guy`s can someone just confirm for me the best place to house the crossfire injectore on my civic type r engine,i know it has to be drilled into the AEM INDUCTION CHAMBER somewhere,just some reassurance from you lot!!,would be appreicated

As close to the inlet as possible, just after the bend looks about right. near the logo.

a bit more of the manifold would help in the picture so someone can give an educated guess at best angle to shoot it as well

To clear this up I'm assuming Jimbo means the logo end by the intake manifold and not the big logo by the filter.

i new that position was going to come up!

probably is where the logo is ,is where the induction chamber marries up tight to the throttle body!! so i cant secure the crossfire there,

in the picture below is a lime green dot,would it be ok positioned there?
reason why i ask is that i have already housed it there,but then thought afterwards i should of asked first


please someone tell me its ok!!

looks okay to me
maybe someone will second it
anyway you could always seal it with a bolt if not, i know i did

thats given me some relief

if someone else could just verify,then i can take the car out and try it!?

its certainly good enough as to not be a problem mate imho
but back up is always good
sometimes you have to play around toget best dispersal, i did.
id try and point it so it hits opposite end of manfold in a way so that it bounces and then hits the back of manifold (ie opposite entry to engine) thats what id try if i was mine!
and remember to do static test 1st dude!!

That position is fine as long as the injector is not angled to spray against an intake wall. If the injector will spray downstream freely then you are good to go!

Thats the position l was meaning, l have a prelude with the 2.2 VTEC engine the inlet side is much the same. l have my crossfire fitted in the side of the pipe, at an angle. The main problem l had was finding a coolish location for the pulsoids.

i had same problem as you know the type r engine`s bay gets extremly hot so housing it anywhere in the engine bay is a no go!!

i housed mine in the skuttle where the window wiper motors are!

problem is the nitrous and fuel lines from the soliionds to the crossfire injectors are longer than most peoples,i.e mine are about 14 inches long,
i hope this will be ok,my only concern was that it would take slighly longer for the NOS to engage!

is that lengh of nos and fuel lines ok!
can anyone confirm
AND TELL ME THIS IS OK!!

if i lose a bit of BHP im not fussed,i just need to no its not going to cause any damage to my engine as the car is only 14 months old?

Mount the Pulsoids just behind the o/s headlamp as near as possible to the intake pipe.

Run the pipe through the car then through to the inside of the wheel arch (the wheel side) then to the front of the car and enter the engine bay at the front near the headlamp.

thanks for replying trevor

are you saying that where i have already housed the polsoids is wrong!

will it cause any damage running your nitrous kit the way i have done it!

are those fuel and nitrous lines to long?

it wont damage your system but will hamper the performance.

i had a similar prob when i did the whole scuttle plate thing with a silvia turbo.
the longer the transfer lines are then the more "nitrous lag" you will have .

i believe this is due to the nitrous in the long pipework undergoing minor phase change and not being as dense.

believe me if trev says xyz will make your system better then DO XYZ!

the guy knows.

what hes sayin, or i think hes saying as its not wrong as such, hes just tellin you the best place from experience.
+14" is quite long, mine are only about 8" and im gonna shave them down to about 6" when i get some spare olives.
aim for 2" lines rather than the 12" it says in manual
short and cool (it makes more differnce than u wud believe)

If you follow my advice you will get quicker acceleration and greater engine reliabillity.

It will work as it is but it means there is lag (as Dave said) and it means the nitrous gets to the engine way before the fuel which causes it to run too lean for a period of time and that's not good for reliabillity.

thanks trevor for help with relocating the pulsoids,just for reassureance can you from this pic tell where you mean exactly

Could do with a pic that shows the full front of the car but from that one I'm guessing near the battery as I'm assuming it's behind the headlamp.

Regards

thanks trevor
you are right the battery is right behind the headlamp!

so from that picture you can see a clamp on the side of the battery,would it be ok to house it there,its a nice secure location as well,and is only aprox 3 inches away from where i have housed the cross fire!

If you mean a clamp that secures the battery at the bottom then yes that should be ideal.

Regards

its worth it mate, bit of moving around reaps good rewards.

done what trevor suggested and moved the pulsoids to the front in between the battery and headlamp!

ive now reduced my fuel and nitrous lines down to about 6" in length

and what a difference,on a 50 shot of nitrous now it is unbelievable,its like drivng a different car all together!

i have a minimax to install
yet.the 50hp shot straight in seems fine no wheel spin or smelling clutches


TREVOR,would a 75hp on a controller be ok,

if so ill phone monday and order some!!

TREVOR,would a 75hp on a controller be ok I call this the oliver twist effect, we all suffer from it, please sir can l have some more, addictive isnt it

Yes you should be OK with 75 bhp and a Minimax as we have quite a few Civics with that amount running well.

Regards

excellent news!

ill phone monday and probably speak to ant or ryan

thanks trevor!
