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

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.

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.
