    Motor Change guide for EG * B / D / H / K SERIES !!!!

    Hello Boys and girls and every1 else whos intrested in changne motors in an EG.
    This is for all you Noobs who dont bother to search and keep on posting the Question...
    "Man my EG is so slow i hear an engine conversion will give it more up and go, How much and were blah blah blah"
    so to stop all these threads from poping out. i have made a thread based on my experience and the rescources found on the forums.
    *any info you think is incorrect please correct me*

    EG's come in both Carby and EFI form
    Carby equipped cars are

    EG3 (Breeze)
    EG4 (GL/later model Breeze)
    EFi equipped cars are
    EG4 (Gli)
    EG5 (Si/Vti)
    EG8 (Gli)

    Engines Available..

    Okay. to be honest there is a heap of engines that can fit in a civic. starting from our 1.6L SOHC VTEC engines to the V8 Chev engines. All these are possible with the help of our friend money, ALot of it.
    Anywayz we'll just focus on the most common coversions.

    B16a Engine cnversion (DOHC VTEC )

    So far the most common and popular engine conversion.
    the B16a is found in many civics starting from the EF9,EF8,EG6,EG9,CRX DELSOL,EK4, etc
    though since the australian RTA rules stats that putting an engine that is old than the chassis is illegal. (ie puting a 92 model B16a into a 94 model GLi is illegal)
    Putting a B16a into a EG is pretty simple. half cuts can be bought for 3.5-4K
    though the B16as are getting rarer and rarer and pricier due to the popular demand.
    these are rated at around 125kw for a JDM spec and 116Kw for a AUS spec B16a2
    Some of us maybe confused by the engne codes (ie B16a, B16a2, B16a3,4, etc. Do not be afraid it is stll a B16a it just tells u where the engne was intended for.
    B16a (JDM only sold in japan)
    B16a2 (AUDM and some Asian countries )
    B16a3 (Asian and European markets etc)
    B16a4 is for another non JDM market

    here is a DIYarticle that i put together some time ago
    http://www.ozhonda.com/forum/showthread.php?t=5953

    B18c Engne coversion (SIR-G/VTIR/ Type R) DOHC VTEC

    This engine conversion is also pretty popular.
    B18c engnes can be found in DC2 integras. B18c is the SIR (JDM), VTIR(AUDM) or the GSR (USDM) motor. this engine is rated 125-130kw depending on the specs.

    The B18cR the most hardcore out of the box Honda DOHC VTEC engine.
    these motors are rated 141KW for the AUDM Spec and 145KW for the JDM Spec.

    compared to te B16a's these motors are very torqey. the B18c SIR and the B16a might have the same peak power but. the B18c's extra torque gives the car a very fast point to point acceleration.

    Heres a DIY artive done by ECU-MAN (GOD OF DIY )

    http://www.ozhonda.com/forum/showthread.php?t=30312

    B18c halfcuts can be picked up for around 4-5K for a JDM SIR-G cut and
    7-8k for a B18cR cut depending on the specs 96, or 98 spec.

    H22a Engine coversion Prelude SIR/VTIR/type S

    This engine conversion i am not familar but.
    these engines can be found in the Gen 4,5 prelues, Accord Type R's etc
    H22as can be picked up pretty cheap compared to the B serise has they are not as popular.
    H22a's are very very torquey. There are few cars on the forums with H22a's and the can run mid to high 13's easy.

    A DIY ariticel Done by Honda B blastn
    http://www.ozhonda.com/forum/showthr...highlight=h22a

    H22as are rated at arond 142KW. but custom mounts such as hasports etc are needed to fit in into a EG

    General Questions Asked

    Here are some of the General Questions that i have seen on the forums that have been asked so many times.

    Q.Do i need to upgrade my brakes if i do a engine coversion ?
    A.Yes you do for safety (stop better) and to get a engineers certificate

    Q.How much would a work shop charge me for labour?
    A.1.5-2K depending n the work shop rate

    Q.Can i use my old ECU for the new engine
    A.No you can not each ECU is designated for each engine

    Q.Can i use my old gearbox for the new engine
    A.Yes depending on the engine if you have a Bb16/B18c gearbox and want to match it to a another Bserise engine yes u can. other wise No

    Q.Can i use my stock exhaust on my new engine.
    A.Yes but only up till the cat. the headers will be different if u have a different seriser engine ( ie D serise header wont for a B serise engine)

    good info
    BUT i think u got some power figures wrong.
    jdm b16a isnt 125kw atw, and aus b16a isnt 116 kw atw.
    maybe you meant horsepower?
    or just 125kw (170hp) and 118kw(160hp). NOT atw.

    as far as the whole b16a2/b16a3 argument... the designation isn't really where it's from, as much as when it's from...

    here in the US, the b16a3 was the obd1 motor, with the a2 taking over with obd2... same in europe, etc
