[REQUEST] How to install SRI on my 2003 Jazz VTi GD3

[GU357]

Hey guys I've got a 2003 Jazz VTi, ie 1.5l Vtec. I bought an APEXi air intake to replace the stock airbox.

Unfortunately instructions are in... JAPANESE!!!
so i have no idea wth to do.
I get the remove original and mount the new one, but what about sensors?
how do i reconnect them?
how many are there?

and how many pipes are there all up (besides the main inlet)?
- Including crankcase breather, and any other tubes/sensors that are connected to the stock airbox that may have to be redirected or plugged into the new manifold.

[flipfire]

Just look for where they go.. its pretty easy. I think there was only 2 when i last looked, the round MAF plug and breather hose.

Doesnt the instructions have pictures?

[GU357]

it does but poor quality and some parts i have no idea where they've got them from.
im presuming the MAF plug is the little sensor in the back of the stock airbox yeah?
it says i take that out and put 2 other things on it which i dont understand

[M@lew]

Basically just take out your stock airbox, everything what you see. Then depending what intake you have (pictures would be good) it just goes over the throttle body, the breather is the extra "mini" tube that was there and the sensor should plug straight into your new intake, it's super easy. Here is a picture for reference, this is an intake that my mate and I built for his Jazz a couple of years ago.

errrr... its pretty straight forward man just plug in what you unplugged when you removed the stock air box.... you only unpluged 2 things which are 2 map sensor and the crank ventilation hose... how hard could it be? if there is only one hose on the new intake arm you would hope the kit cant with a lil breather as pictured above...

Seriously tho, try search online for pictorial guides,

[GU357]

oh thanks guys, i found out what the pictures were on about, the rubber grommet was a pain to get out....

thanks guys
ill take a picture soon :D

only one sensor

[flipfire]

How is it with the SRI? more responsive?

[GU357]

yeh it is. only slightly, still have to try it with the vtec valves open.

Just by the way the crank breather isnt aloud to be separate to the intake.
it has to be routed back in, so that it doesn't "pollute".
- So iv'e been told.

[EG52NV]

The apexi intake looks nice

[GU357]

yeh its ok, but took some modifying to fit.

and the pipe isnt as smooth as it looks. its cast and abit rough, so not perfect airflow.

from factory the brackets dont fit well. i modified one of them with some bending to get it to fit, so im only using one bracket out of the 2 i got.

if i used both brackets take forevrer to get em both perfect to bolt onto, and from new the brackets held the pod too high bonnet wouldnt close


other than that all good :D

[GU357]

yeh the bracket holds the end off the pipe up for support. is bolts to a spot inside the engine bay where the original air box was screwed on.
other wise the pod falls and lies flat onto something, or possibly falls off.

[gre03]

first of all sorry to reply to a dead thread, but i thought it made sense rather than starting a new thread based on the same topic.

so i'll looking to make up a DIY SRI based on an intake a guy on FitFreaks.net made. apparently its been really successful on the forum.

my only question is what are the sizings that i should the pipes etc in?

cheers

[GU357]

ahh claymore made a diy intake on the jazz forum which died a while back

can u link us the DIY whihc u refer too and if its anything like claymores one i can give u sizes?

[GU357]

also whilst on this topic i was told the jazz doesnt have a MAF it uses a MAP sensor (Manifold Absolute Pressure) which is plugged into the plastic manifold on the top.
and the thing that your plugging into the intake pipe is actually a thermocouple (temp sensor)

i think you'll need an account to view the thread though. if you want i can just post the post here.

[GU357]

hes using 3 inch pipe bro. but others there are using a 2.5inch
i reckon the 2.5 inch be easier to work with being thinner but harder to get filters for.

thats an extremely basic system.
what u really want is for the pod to sit under the headlight but infront of the front splash guard, but u have to cut the webbing for that, but its very cool in there. or put the pod near there and use a filter shield, u can go to repco they sell the filter shields for like 20 bucks,

[gre03]

so its 3" for the main piping and pod, but what about the breather? i rekon putting it in front of the battery will be enough for me. if i need in the future i could probably extend it down into the lower section.

[GU357]

yeh or u can put a cylinder around it with a 3 inch cut out so it forces air to be sucked from that direction.

gl getting the silicone hose tho, i think u really need a 2.25 inch but most places sell 2, 2.5, 2.75 and 3 and so on

[GU357]

air breather can vary, but most likely ur smaller sized ones. i have a brand new one i was gonna use when i made a new intake for my new s90 Throttle body, just look at the size of the pipe that plugs into your air intake and u can guess the right size. most ive seen dont even list a size on them u just compare lol. but dont get me wrong there are different sizes

[gre03]

thanks for your help mate. wasn't sure if getting chrome/alloy piping was the best in terms of thermal conductivity, but doesn't look like i have much choice

[GU357]

U can sometimes find rubber or silicone in the right shapes but if Ur really worried make the system up and then exhaust wrap it. Or use the foamy silver stuff that looks like astraunaut suit material

[gre03]

can't seem to find any metal piping anywhere so looks like i'm going pvc. not entirely sure how i'll fix it to the tb and filter though

[gre03]

do you know how to remove the stock airbox? seems like there are a few tight clamps holding it on

[flipfire]

Maybe you can find carbon elbows.. i wanna add a second elbow to mine

[gre03]

notsureifsrs

[GU357]

the air box is held in by a couple screws underneath, so look around edges.

if not just undo everything associated with it, til it comes off.

for metal just go to autopro or repco they sometimes have that stuff.
not sure what shops you got over in melb, worst case go to a turbo shop or a store that sellls race products they would have some too.

to mount to tb u want silicone or rubber hose, the tb has an outside diameter of abt 58.8mm or 2.31 inches, so your hose needs to be from 2.3inch to 3 inch. rubber hose if u get a small size will be easier to stretch over the TB where as the blue silicon stuff is quite strong.

hope that helps man.

[flipfire]

Ive been trying to find a second elbow for mine to reach the air feed pipe (from the stock air box)

[gre03]

thanks for the info GU357. all shops are closed today because of the public holiday, but i'll have a look over the weekend.

[GU357]

flipfire i think ur better off with it that way, 2 90 degree angles starts becoming restrictive.
because air holds velocity.

so atm it would be roughly like this. where the red represents air flow path, and the blue represents the area now lost due to corners and bends. unfortunately air flow isnt like water flow. usually these blue spots carry stagnant or turbulent air that doesnt move or is not useful.
http://i1184.photobucket.com/albums/z332/GU357/airflow.png

so with 2 elbows this might be worse, but its hard to say, and very much dpends on how far the bends are from each other, and waht the actuall speed of the air flow is. but its good to keep the diagram in mind i guess.

so gre03 when u do make it try get bends that are smoother and have the 90 degree bends as close as possible to each other, so u can preserve the flow path.

[gre03]

yeah i was going to try either 2 90 degree bends or one 90 from the tb and a small 45 to get the pod closer to the battery area but not as sharp a turn as 90.

[GU357]

hmm 60 degrees is popular (ive seen it around) but u could try get a 90 and cut it into 2 pipes (Y) that could work.

[gre03]

whats the deal with pod filter types?

i'm probably just going to get the standard type of pod, but i heard there's oil and paper types.

[GU357]

some pods are dry filter packs and some are oil'd the oily ones have better filtration but require more cleaning and possible replacement, dry filters are as good a "filter" as such but gives you more consistant less maintanence filter. if that makes sense?

usually foam ones are oil'd they work very well for like 20,000km's but after a while they get cloged because the oil is helping the filter pull and trap the dirt from the air, so it needs a clean out and re oil, or possible change.

but an apexi dry filter is still washable but it doesnt pull out as much dirt so the filter will actually last longer because it doesnt require the same amount of maintanence but ur letting more dirt into the engine, but if the dirt is small enough to get in through past the filter its debatable whether or not it would have any real negative affect.

up to you, oil'd is the best in theory with regular cleaning, but if u CBF just dry running is ok for the city.

[GU357]

flipfire does the carbon elbow detach from your simota charger?

[flipfire]

Hmm yeah your right, i might just extend the air feed piping instead.

The air feed pipe sticking out is connected to an enclosed resonator near the bumper isnt it?


flipfire does the carbon elbow detach from your simota charger?

The elbow isnt carbon, its thick rubber. Only the cylinder part is carbon fiber and yes it can be detached.

[GU357]

the original air cleaner is a pipe attached to a filter box which has air fed to it through i roughly designed path that leads from the front bumper, i dont thing if u extended it you would really get much cooler air, because the thing thats there isnt a full pipe, theres gaps and the air also flows through the webbing behind the headlight, its not a direct feed so to say.
cant really explain it.
so heres another diagram
