    Default Engine Swap in Nissan Sunny 1991 (B13)

    AoA,

    Thread update: Swapped the engine with EFI one after wasting double the money on overhaul. Details of swap from page-2

    Guys I recently got a Nissan Sunny 1991. Currently it has a carby 1300cc engine, which frequently gives bluish white smoke, particularly, during start ups. Its very generous in eating up the engine oil.

    Many have suggested to go for 16 valve twin cam EFI engine. One guy told me that he visited Ahata Mithu a few months ago and got 12 valve engine swapped for 17k, while 16 valve engine was available for around 24K.

    Would appreciate if someone can guide me about best engine (I prefer EFI), the prices, the best place to get engine and best workshops to get the Nissan swaps done.

    Thanks

    you are alway's welcome to share the actual result's and repeated visit's of the vehicle's on whom I had worked. As you are alway's misguided By the honourable peaople around you you can fullfill your desire. And one thing more peaople visit's us for more information and plus if they just come around for the cup of tea they had to bring their vehicle's along with them not to worrying about saqib bhia who feel's that they are coming for the again again complaint's ....... grow up big brother .....

    I am not liable to give you an explanation. Just do what you do without dragging me in any way. I hope it is clear. And I gave you clear hints about how I know who but u want to assume it yourself. You are free to do that. What me and mustafeez do with each other is none of your business nor do you have any right to throw mud around.

    Atta bhai, leave all this, just please elaborate this point that you mentioned that Nissan Co. Japan are not capable of fine tuning each engine and so they leave room for tuning it by the extraordinary tuners like your highness.

    Secondly, would you care to share that what will you tune in the first place in a 128 hp QG18 which is meant for a sedan and meant for economy ? Do you think, this engine cannot be tuned without the so-called Consult 4 and requiring a tuner like your highness? Are Nissan Rawalpindi not able to tune out according to your taste with their pathetic Consult-II ? or are the incompetent and only you can tune it and all the Nissan Sunny's that are being sold after 2005 are standing in the Ternol Pathak ? waiting for you to get them tuned ? Can you enlighten me ?

Can you enlighten me ?
    first of all you guy's alway's misunderstood the statement's .
    Second every manufacturer in our case nissan is not capble to tune and optimize every single vehicle because they dont know the condition's terrain . climate condition in which the car has to be used so they design a single specific map in which they write the specific fuel and ignition timing table and plus many more feature's which are stored in the Ecu rom and upon input's from the different signal's the CPU calculate's and compare's those value's with the pre stored map and hence able to respond in result.

    the above is the short intro to the Map and what ecu does What company do is that it cannot write the individual Map's for each engine it will take much time for example if the manufacturer build's 500 vehicle's in one batch and has to compleate them and depart them to dealership's in one month If we say them please tune each vehicle and optimize it perfectly the 500 vehicle's batch will take approximatly 5 to 6 month's for the perfection and lot of man power to individualy optimize the engine. So what they do they write a basic map with some room to adjust with the imperfection. But it is not the 100% optimized engine. So manufature's make and depart the vehicle's on due time.....
    As far as the concern of tunning individual engine I am giving you an example of your QG-18 series engine. The engine which was manufacture's in 1998 is less efficient than manufactured in 2006.\The question arose why?
    The answer is:
    The map which was designed and written in that year of 98 is much inefficient as compared to the map designed and written on 2006 ecu So hence the performance also fluctuate. there are alway's few improvement's done in the Engine mechanical part's if a series is manufactured from 98 till 2006 but much more improvemnt's is done in the Basic map.

    They had this option in C4 to reduce the customer's complaint's in different region's Hamaray mulk mein to sab chalta hia ...... like Vit'z and honda knock knock knock why the honda has been updating their ecu to supperess the common knock issue because those vehicle's were not optimized perfectly so they give a soloution in term of ECU Update (Basic Map update to coupe with Knock suppresion).

    ..Got it Ya haji saab ko bulaaon ....... wohi banda tumhein samjha sakta hai mein to type kar kar ke pagal hoo jaon ga ......

    I am not asking you that I am gonna tune every nissan which is been manufacture since ever......
    hence the dealer ship's are not yet upgraded like the dealership's abroad are updated Even here the dealer ship's are ot entertaining such issue's like ECU and wiring troubleshoot One of our fellow member had gone through the Rawalpindi dealership and can explain better if asked what those fool's there told him. If you dont belive so put an fault in your vehicle like ( Cut the vss signal to the TCU and take your vehicle to them and ask them to trace and repair the fault and just stood there quietly just as you dont know any thing about Engine or EFI Wiing and about the TCU or wiring stuff and see what they will do to your ride You WILL BE LIKE PAAA GGGGG MEINTENOO ZINDA NAHE CHOORAN GAAAAAAAAA..... We all do repair our vehicle's far better than those Loot dealership's.. go ahead and try and stop saying about tuning the nissan's by me I am fed up with the ustaad g kare gari .. which he do to these peaople's so let me remain in my sense's....

    sorry yaar, cannot read this long of a post, but certainly can answer this one.

    Atta bhai, what is so important in that diagram that you do not want to reveal it ?

    What would happen if he reveals it ?

    Maybe one or two guys in the future would get benefit of that and that's it ?

    At least I'm not interested in QG18 anymore, so I don't need it.

    I'm trying to find out some missing parts for QR25DE, so yeah, you can help me out there, but I'll surely not let you change its "MAP"

    and please, stop this "Haji Sb" bUll$hit. @spectra is a respected member here and I think you should acknowledge that as well. Plus, he already has given you appropriate warning. So, I suggest you avoid doing that.

    "Second every manufacturer in our case nissan is not capble to tune and optimize every single vehicle because they dont know the condition's terrain"

    yeah, a multi-million dollar company really don't know which product is going where which is manufactured in its company.

    atta bhai, Nissan Muridke ki company nai hey key they don't know in which part of the world and in which atmosphere they are sending their cars. That is why, QG18DE even comes in so much variations, because they are built for different terrains, atmospheres, as well as different conditions. @Xulfiqar bhai says right "screw those engineers that design engine" lol. You talk so sense-less. I did not want to say this sentence since long time, but you have the gutts to let me say it today .... Please, leave this meaningless behas. You are not convincing me, it is bullying.

    I would request everybody to keep a cool head on this thread.

    And I certainly don't wanna get the diagram now, as I have almost fully decoded the Russian version myself with the help of Almera N16 manual. Just 10% decoding remaining, which I'll accomplish today, IA.

    Thanks bro. This is available with me. 3-row ECU pinout isn't available on the internet. But I've got hold of it through a Russian manual and subsequent 1-1 mapping with Nissan Almera manual.

    Yes - I have, it was in GM proving grounds in detroit.

    Lean burn ranges from above stoich all the way upto 40:1 - The cat melting (burning) due to extra fuel is not the same as cat decay due to high EGT and high NOx.

    For the guys on this forum, having got some knowledge and experience, paying for same expertise may be a bit hard to digest.

    And regarding my car, I decided to get my hands dirty with wiring stuff. Will be happy to pay for the support, if required from you, for consult-4.

    I believe for retarded timing, crank sensor is responsible and if I can fix it, no need to fiddle with timing map...!!!

    first rule out why the timing is showing up retarded.. The ECU is actively controlling ignition events, If you have laggy acceleration, bad air flow signal, bad o2 activity and knock count detection rising fast - the ECU will trim back the timing.
