   I swear i have seen a thread asking about this before, just cant find it..
   
   I assume its going to fuck the system right up if i was to do it? but it just seems like a useful mod?
   
   Correct me if i'm wrong.. if i was to do this will it make my car run all lumpy and horrible without a remap, just chuck it on.. or will it just not do much?
   
   thanks in advance! just want to get some of the power out of this engine.. used to the R lump now..

   If it has a wider throat will it not line up to the mani? guessing it willtickover shite

   The bore is larger than the furio body

   surely you could use the whole vtr inlet manifold ?

   To be honest I'm pritty sure a furio has the same sensors in the TB as a vtr, it shouldn't reli affect how it runs, the difference it will make will be fairly small and the ecu will easily cope with such a small change

   So we are saying yes? i mean, any minimal gain will be fine, im going to service it, i know theres not going to be massive changes, just some better throttle response will be good aha!
   
   Breather mods are all thats going to happen tbh, need it running smooth and a bit more pull even if minor, so is this worth doing then?

   If your going to do it you might as well get a polished vtr bodie.
   The gains will be small, but you might get slightly better throttle response

   Id say it will make the throttle response worse. if you have a wider throat for the same gas flow, then the butterfly flap will be more closed all the time.

   Found an interesting thread on it, apparently better response and pull lower end http://www.saxperience.com/forum/sho...d.php?t=219960
   
   will be more closed? explain?
   
   There is a picture of the huge difference between the normal butterfly valve and the vtr one. There is a huge difference in size, im going to do it, its not hard and i cant think of a reason other than cpu calculations that may make it a bit iffy..
   
   If its not worth doing its easy to reverse.

    as I said in that guide the difference won't oh fuck me this is good. It makes a nice difference mid range when overtaking stuff also low end of the revs pulling off but when higher up there isn't a huge amount of difference will run and idle fan as long as you do it pretty much as per guide.
    
    Been ages since I've done a single plug inlet mind you

    They are talking about swapping a manifold and tb complete. What I meant was if you have a larger throat on a tb say 1/3 more area, then if the engine is in mid range and you whack it open, the airflow in the tb will be slower and slower to rush into the gap left by the wide open butterfly valve- hence wotse throttle response, Response means sensitivity to your inputs it doesnt mean pulling power.
    
    If you are just cruising, the butterly valve will me nearer to the closed position with a wider throat tb, than with a proper sized tb, this part should b obvious

    Another thing in this link they are talking about leaving the standard airbox in place- that is daft it will reduce any performance gains. The whole point of the bigger tb is to allow a hohjer maximum gas flow but a standard airbox will just restrict it

    Guide is useful, do i have to change the entire inlet manifold, can i not change the throttle body alone?
    
    I understand it wont be incredible. Breather mods often dont do much but im looking to squeeze what little i can out, and a bit of pull that wasn't there before would be great. Im used to driving a VTR, so much lower tourque, this just feels dier compared to.
    
    Obviously my TB will be different because its not an earlier westcoast/quikky, but i assume so long as i get the mk2 silvertop VTR TB it all still applies virtually?
    
    cheers!

    Just had a read, i didnt realise the manifold was to be changed, as said seems like a lot of work for minimal gains, and i understand what you mean by the change in air flow when opened fully, makes sense.
    I dont see how changing the full inlet and TB increases performance in that case. is there a large difference that im missing here? the inlets look virtually the same to me, but im no expert, and yes i know response means... response

    Ive found the rallye s2/xsi throttle body to fit the VTR inlet but is much larger and opens further. Might be worth looking at, can get photos if you want

    The inlet and TB are wider which obviously means more air entering the engine
    = bigger bang = more power etc
    
    Pretty simple , exactly the same reason people put Rallye inlets onto early VTRs

    bumping this up as it's something im going to look in to doing in the new year.
    
    im not expecting massive, if any gains, but after seeing how restrictive my throttle body actually is, it can't hurt, can it?
    
    are they plug and play if i find one from the same year?

    yeah plug and play,
    Personally noticed alot of gains, alot more throty, quicker on pick up
    
    Idle at first, idles high then it sets back down and will be fine, but give it a day or 2 to settle in then it will run well.
    
    Had mine on for around 2 years no problems.
    
    port spacing different on 3 plug and one plug ecu
    
    1 plug
    0000
    
    3 plug
    00 00
    
    Mines one plug, they just bolt straight on.
    
    Wires do stretch abit but all work.
    
    I used all the vtr sensors.
    
    Theres some points mate hope it helps.

    Make sure all hoses are air tight, no leaks otherwise it will idle iffy.

    Thats probably the best reply your ever get on sax-p. hah have fun dude.
    
    Ow and its pretty easy to fit yourself give your self some time although as things can get fiddly, say 1-2 hours. The nuts at the back of the inlet manifold are 10mm some are quite tricky and fiddly but not all bad !

    Why Not 16v it! Engines are dirt cheap . Faffing around for very little gain in my opinion.

    roughly £350
    fitting £250-£500
    
    At the least its £550
    
    I would do it myself so around £400 still, and when a saxo is around £900-£1000 to buy its hardly worth it.
    
    Plus then what do you tell the insurance, tax etc.
    
    If it wasn't this time of year i would be looking for an engine it has crossed my mine to many times. I've looked for a while and its hard to find a decent local set up for sale.
