I've read about people swapping their current engines to make them faster. Now what Iwant to know is for a 99/00 civic Si what is an engine I should swap to,but at the same time not be too expensive?And is possible please explain the different engine types and what theyre for. I keepon reading about B16's and B18Ci's and B18B.. Whats the difference????Thank you very much.

 

Your Civic has onboard diagnostics (aka OBD)and there are three different types: OBD0, OBD1, and OBD2 . . . yours is OBD2. To stay emissions-legal in California as well as many other states, you will need to use an engine from the same year or newer and that meansit will be OBD2. As far as the engines are concerned, there are many series of engines (D, B, H, F, K, etc.). This is the first letter in the engine designation. The next will tell you the displacement. As an example, D16 is a D-series motor with a displacement of 1.6 liters. A B18 is a B-series motor with a 1.8 liter displacement.

The last part of the designation isn't real standardized, but I can try to sum it up:
1) If an engine designation ends in a letter (B16A, B18C)it is JDM (Japan Domestic Market) except for B20B which is USDM (United States Domestic Market)

2) If an engine designation ends in a number, it is either USDM or EDM (European Domestic Market)

3) If it ends in a number, the number is only an indication of the sequence in whichit came out. For example: A B18C1 came out before a B18C3, which came out before a B18C4, etc. Note that they skipped the B18C2 completely and went straight to B18C3.

The part where it's not very standardized is that the A's, B's, C's, etc.don't necessarily mean the same. B16A's and B16B's are VTEC but not B18A's and B18B's. The best I can do here is to give you a few links which will help you greatly. Theyshould give you most of what you need to know.

this is misleading.... it's not like the B18C5 is just a "newer" version of the B18C1.

take a look at this thread, it should give you a better idea of what swaps are available

mxs,

Goodcatch! I should have stated that. I know exactly what you mean: the B18C1 is a GSR motor and the B18C5 is a Type-R motor . . . the heads are different.

 

look into either a b18c1 or b18c5 to swap into your car

 

i would save up for a turbo and just turbo the b16 that is already in there. its a good motor to turbo

 

i agree with aryiman. turbo the b16 and call it a day..

 

^ +1... you already have a great engine. In fact, many people swap out their sohc D-series engines for B16's. Just turbo the engine you have. It'll probably get you more power than simply swapping to another engine, anyway.
