Simple guide to fit a S1 rallye inlet and t/b onto a vtr

2nd October 2008, 15:41

Here's a quick guide which goes over all the connections that were required to fit the inlet onto my vtr (and it all worked fine).

The idle control value stay's on the left of the inlet and can be connected like so:

This is how i connected the map sensor up, some silicone and a screw held it in place with no air leaks:

The ecu breather pipe needs to be connected up and can be done like so:

The blue plug on the bottom of the throttle body connects to a grey plug (the grey plug has two green wires going into it):

The yellow plug on top of the throttle body connects to a black plug (the black plug has a yellow and brown wire going into it):

The throttle sensor with 3 wires (black, black/yellow, black/red) connects to the black plug with 3 wires (grey, brown, grey) and has to be connected like so:

black wire to A
black/yellow wire to B
black/red wire to C

A pipe from the bottom right of the inlet needs to be connected to the brake reservoir:

Last of all...connect up the throttle cable and enjoy! (a 106 throttle cable will need to be used as the throttle opens the opposite way and the vtr one is too short)

and does it actually run ok?

9/10 results say no.

why do people do this mod? dont even think people do it these days because of all the bad results.

2nd October 2008, 16:16

what do the 1/10 people who have had this done correctly say?

2nd October 2008, 16:18

mine ran perfect...idle was fine and noise was lovely, the actual inlet itself is like 3 times bigger than the vtr one and its made out of aluminium which gives it that nice throaty note

with it on you notice a slight power increase, the real gains are made once a remap is done (which i never got around to do)

2nd October 2008, 16:22

all i ever read about it is people had a dick on trying to get it to work

good guide though

2nd October 2008, 16:38

Really considering this, will it only fit the mk1 engine or will it fit a silver top mk 2 03 plate vtr??

Cheers mate, did a search and saw this so thought i'd just ask to make sure!

so if i fitted a 90bhp head on my 98bhp block then the rally inlet would fit??

6th October 2008, 00:31

G187's inlet manifold is now on my car, and after 5 mins or so of it revving at 5k the ecu sorted itself out and it idles perfectly

the guide was really helpfull too. and can i just add that the lower 2 bolts are a proper bitch to fit, and make sure there all done up tight

i'd only do it if fitting certain cams.. the standard VTR inlet manifold just doesn't cut it

11th February 2009, 16:13

sorry to bring up old threads but il be fitting one of these at the weekend and was curious for anyones experience of gains, also is a 106 throttle cable a MUST as it says earlier in this thread youe may need 1

11th February 2009, 16:29

yes, new throttle cable a definate must, saxo diesel also fits. you will love the sound once fitted mate

11th February 2009, 16:40

yeah? gr8, only really fitting as im awaiting my ph3 and pulley arriving, is the noise that much different?

11th February 2009, 16:55

what induction kit do you have on? it will make a throatier noise from the engine, sounds awesome

11th February 2009, 17:31

just a shitty open filter, loud but not good, its too big and is sucking in alot of hot air, i have a green induction kit but am in the middle of decision making on which route to go induction wise, jus waiting till all arrives to get cammed up then going to fit all at once and bask in there power increse lol

11th February 2009, 17:37

well the exit of the inlet manifold were the hosing joins on has more of an angle on it so you may need to reposition that slightly

11th February 2009, 18:01

no probs m8, unless i go the raceland route will probs be custom piping anyway, cheers for the info,

14th February 2009, 18:40

good guide, have jus fitted and my idle is 2k, when i rev its taking its time to drop back down to 2k anyone any ideas was thinking icv?

15th February 2009, 12:25

anyone? i need this sorted today if poss

15th February 2009, 12:34

reset your ecu its probaly still trying to idle as if you still have your vtr throttle body on

this 1 is much bigger there for id say the sensors are sensing not enough air in the enclosed part and drawing more in hence why the idle is at 2k

try disconnecting battery if you havent already...

i take it you've followed this guide to a T?

also try find out if the was diff versions of the body...dont think there was but check anyways.

15th February 2009, 12:51

looks the same as the guide, and followed the guide as well as could be, i tried adjusting the idle screw but it appears that the butterfly is closed even when is revving at 3k which makes me think tha its drawing in air from somewhere?

15th February 2009, 12:53

you put the bolts on to the correct torque setting for the inlet, fit new seals etc?
cleaned the ICV and other sensors? where you have drilled the hole for the ICV its not seeping in air around that area is it?

15th February 2009, 12:56

Will it fit a furio?

15th February 2009, 13:00

didnt have a seal so i just siliconed it as it'l be comming off again next week to fit my cams and i can put a new gasket on then, just wanted it all in and running ok before i start pulling the head off to cam it, icv is on the left fitted with an airline fitting, going to check all seals as you haved to blank a few pipes on the mani and 1 on the tb, would really like someone whos fitted to talk through it and make sure ive got evrthing in ok?

15th February 2009, 16:11

this only fits the mark1 versions right?

15th February 2009, 16:15

yeah only for mark1...

looks like hes tried to fit it to a mark2 tho... but arent the port spacings different?

what does the mark2 tb have that the mark1 dosent?

15th February 2009, 16:17

the reason it idles like a dog, is because the s1 didnt have an icv....

you could try buying a new icv and starting a fresh, but its £65 for a new one.

resetting the ecu does'nt do anything, tried this and it didnt work....

the thing to do is.....pull the icv apart (pull the shaft out with the rubber end on) take the spring out, then get a 1/2mm washer and put that on, this will stop the plunger fully returning.....

can he not adapt the ICV from his original TB?

iv seen this only mark1 and idles perfectly, so why would the mark2 be any different

different cam? maybe.

you can adapt the ICV, i will try and draw what i mean on paint.

15th February 2009, 19:14

mine a 90bhp silver top, single plug, fitted and all is ok but idles at 3 k, ive drilled tapped and fitted an airline fitting onto left on s1 inlet and joined my saxo icv to the fitting witha bit of rubber, what were you saying bout stripping the icv? need this soerted asap or its gonna fry my clutch

15th February 2009, 19:16

also the throttle has an over run? takes a sec or 2 when in gear to drop revs when you let up, soon as you drop the clutch pedal it drops revs for a half sec then flys up to 0ver 3 k the slowly settles to3 or just over?

25th February 2009, 15:56

probably a bit of a n00by question but is it a Rally inlet of a 205 Rallye of a 106 Rallye or something else? and anyone had it done and properely mapped with cams? what sort of gains?

25th February 2009, 21:28

106 s1 rallye m8, lots have done it, gains are ment to be much better an sound much better too, jus the inlet and tb on mine with the induction 4-2-1 and full sytem has greatly improved, cams go in this weekend then a map and ill let you know how it goes

25th February 2009, 21:59

whats teh difference between S1 and S2? is it like the 90bhp VTR and the 98BHP VTR?

26th February 2009, 12:11

s2 is the same as the vtr inlet, which is plastic, so using the inlet off s2 will make no diff, but the s1 is alot bigger and made from steel (i think lol, cant remember) so with this you get better airflow and intake etc

26th February 2009, 20:47

s2 is same as vtr as said, s1 is something like 3x bigger i beleive but dont quote me and is made from aluminium, really tidys up your engine bay too, i think it looks alot better,

6th March 2009, 20:36

does any thing connect to the big black thing on throttle body as there is a big plug on the thing that says magnet merell

5th April 2009, 16:31

This is a pic from an old ccc mag of a saxo mk1 black top,with s1 inlet and enclosed airbox,and richard longman head work,with 160bhp.

i will have some piks soon fitting the inlet to a vtr engine with quiksilver/westcoast wiring just fine tuning the wiring

what Cam would you fit and whty??

7th September 2009, 16:42

the lairiest camshaft you can fit is the ph3 or equivilent, this will need the s1 as it wont idle propeprly as the standard in let is too restricive

7th September 2009, 17:02

understood, thats what i thought tbh.

my saxo has 13 row mocal with thermostatoic end plate, 4 branch exhaust stright through, with the pollished up 106 rallye inlet fanimold added i will cant a cam next. I want to run it about 135 - 140bhp with a rallye or xsi box, but bullit proof internals, bit by bit i want to by con rods, big ends etc etc... then map it to rev its tits off....

what cam would you recomend to reach 135 - 145 bhp with those mods?? mid range torque is what i would like the most...

oh also what is the biggest OE radiator you can fot the the saxo? I could have go a Peugoet 405 GLX rad for £20 earlier...

7th September 2009, 20:05

getting a vtr to that power will cost a SERIOUS amount of money n/a, and an oil cooler with those mods is too much imo, will be overcooling your oil, with the power figures youll be at youll never get to a temp during general road driving that will require an oil cooler

8th September 2009, 11:06

its lasted well with the oil cooler so far 144k! thats why i have the thermostatic end plate so it only cools when hot enough...

So what bhp would you expect to see with a cam and remap with my mods, plus the 106 polished rallye inlet and xsi box ?? 130??

8th September 2009, 13:13

Could this work on a furio?

8th September 2009, 17:22

dpends on timing, how good the map is,type of camshaft, and generall condition of the engine,and also what other mods, i wouldnt imagine an engine with that amount of miles would see such a high figure but it does happen occasionally, 120-125 is a safer bet, not many get to 130

ok so im looking at 130bhp in dreamland down hill with a good honest fart behind it... lol. 126 sounds a nice figure to aim for then.... Power engineering it rr'd 110bhp with 110lbs/ft that was with piperX open filter and oe fanimold, no cat striaght through exhaust. i have a laminated copy somewhere.

The engine imo is a good egg, if you know what i mean, it seems to be a solid one straight from the assembly line, hense why i dont want to crack it open before i have to. lots of motorway driving and regular oil / liquid changes every 12k, has seen it wear well i hope.

15th March 2010, 19:27

Fitted one of these for Jordy_6969 today, works a treat, started up first time and ran like a dream.

Shame we had to cutup the 57i intake pipe though!

15th March 2010, 19:34

ive just done this using vtr throttle boddie i had mine englarged to match rallye inlet and is spot on

Where is your battery?

17th March 2010, 10:33

Where does the engine breather pipe connect up to, well confused because Ive got no where to connect it to?

goes to catch tank behind passenger head light

19th March 2010, 15:38

does it make alot of difference by fitting these? i am guessing it just gives it a better flow?

19th March 2010, 15:43

increase in torque ive felt...

and the noise

19th March 2010, 21:26

yeah definatley does seem alot better with it and the noise at 5k is cool

29th October 2010, 03:43

as anyone got video of this on there car so can hear wot they sound like thanks

29th October 2010, 13:09

they sound awesome mate, used to scare the shit out of ppl if i put my fooot down, striaght through with 4 branch and piper backbox, green open cone

How did you cure the self reving behavior ? Like u say when ur driving it does that that even with the clutch in. I have. The same problem :-(

19th January 2012, 09:27

There is 2 pipe run-offs on the top of the tb that need blocking up

15th February 2013, 00:35

does this fit a mk2 i got a 2003 vtr the last of the three engines seen on one page someone fitted it to a silver top can anyone confirm?? got a chance to get one ready to fit if soo thanks

15th February 2013, 01:01

no, the port spacing is wrong on the 3plug/late silvertops

21st September 2013, 18:44

Massive bump up but I've tried fitting this over the last few days lads and ladies and finally got round to firing it up (after changing the TPS connector) extending the loom in places etc. etc.

First startup and the engine revs to 5k!

Second startup engine went to 3k then proceeded to 5k until I switched off.

I've rewired the TPS and the two ports on the back of the inlet i've sealed together with some rubber tubing.

I've connected the ICV as stated and packed full of silicone around the join, I'm going to buy some new hose clips (mine are worn out) and look at a more effective way of sealing the two black pipes on the Throttle body.

I have a feeling it doesn't need rewiring for the TPS...

any thoughts all?

I'll report back.

14th October 2013, 12:23

Looking, at your problem mate, it sounds similar to what Blackie had problems with. He says something about 2 run off pipes? 1 needs to be connected and the other blocked off? I am worried about fitting one now. Has anyone got a more up to date or detailed guide?

Thanks

17th October 2013, 18:40

I'm also going to fit one these days, gonna buy the kit tomorrow..
So any information is very welcome!

Did anyone of you tried to fit the inlet in combination with an upper strut brace? is it possible?

9th November 2013, 09:13

Just bought the inlet, and tried matching it to what I believe to be a single plug silver ontop head, the ports line up spot on but not the studs.
Does anyone have any pics of how the inlet bolts on or details of how you've done it?

Cheers

9th November 2013, 12:51

Just had a quick look at my engine, 3 plug silver top, and the port spacing is oo oo, same as the single plug. Confusedddd

8th August 2014, 22:20

Turbobump.

Has anyone who's still around -blackie for example - got a definitive "this works" guide to this? As it seems some have had issues with idle and whatnot.

Just asking as I have an s1 inlet lying here doing fuckall, and it does look the part...

9th August 2014, 19:23

it works

i ran one on my green cammed R for a year and then ran one on the vtr turbo for 2 years

basically follow the guide.. but ditch the OE stepper/icv on te TB(some ppl see to think cutting the wires and using them will be better)

use the ICV thats on the 8v standard and drill/tap/fit to the inlet

if youre putting it on the rallye it should be a piece of piss as it should all plug and play i think mate

9th August 2014, 19:24

if you get any probs just pm me

10th August 2014, 11:04

Fitted the S1 inlet on my car yesterday, but kept the VTR throttlebody just like some other thread described. Saved me from a lot of sensor trouble i guess. Totally no issues, car idled like it always did.
It required to weld custom mounts for throttle cable and ICV, a custom adapter plate for the throttlebody and two hose nipples tapped into the manifold.

10th August 2014, 17:35

was poss a thread i mentioned

i used the VTR TB on my turbo

flipped it upside down and drilled/tapped it into the inlet.

10th August 2014, 20:07

I did this for the turbo car - gab there are pics in my build thread on axoc. When I took it to get mapped they said I didn't need to swap the wires on the tps and had to swap them back again. Weird because it drove with them swapped!

23rd May 2016, 09:26

Just fitted mine to my vtr and idles at about 2k but I unplugged the yellow plug that comes of the throttle body and it runs sweet but what is this plug for guys also it sounds mint recommend getting one if you have the right port spacing looks good sounds good what sort of increase in bhp am I looking at on one of these wikid thread made some slight adjustments but all worked out Oka thanks
