i was just browsing B18's, and i was wondering, if your gonna swap one of those into a 96-2000 EK hatch, is there are particular year group B18 that you should pick? for example: 98-01 B18, or 93-95 B18

I want a GS-R motor, its cheaper and looks like less work. so would i pick the 96-01

anyone

 

Newer= lower mileage.. more than likely better condition... Older = cheaper but more mileage .. i suggest stay with your OBD ..

A plain LS motor is actually less money and work since it doesn't have vtec. Try and get an obd-2 engine as well to make it a little more simple.

 

yes I agree..
As the others have said, its best to stick with your OBD type which is OBD2 ala 96-01. Not to mention if you're wanting to BAR/Smog your car legitimately.

You can technically use an OBD1 engine in an OBD2 vehicle, but you'll need to do some wire & ecu modding - more modding than you would normally do by just staying with an OBD2 B18 engine. Don't even bother with a 92-93 B18 engine as those are cable tranny equipped (you need a hydro tranny which all 94-01 B18's have).

B18B engines are cheaper than B18C engines, but the actual install is the same, there's just a few extra wiring mods that need to be performed (ie. wiring in VTEC, knock sensor, and IAB's).

 

thanks for the suggestions, now don't get me wrong i'm hardcore honda, and i've been that way since i was 14, but i still don't know everything and i've been curious as to what OBD1 and OBD2 are.

for a while i thought it was the wiring of the car....am i correct?

yes OBD1 & OBD2 are the name(s) of onboard wiring and ecu types.
OBD = on board diagnostics, the "1" or "2" is more than likely the generation of the wiring type. It breaks down like this:

OBD = wiring & ecu type for any Honda/Acura's w/PGMFi under 1991

OBD1 = wire & ecu type for all 92-95 Honda/Acura's

OBD2 = wiring & ecu type for all 96-01 Honda/Acura's
but us Hybriders have broken OBD2 down into an OBD2A & OBD2B categories because of slight changes Honda made to the ecu & wiring within the 96-01 life span of the OBD2 wire & ecu types. You can't plug an OBD2a ecu into an OBD2b vehicle or vice versa. There's a few exceptions with the wire harnesses though.

OBD3 = this isn't real, but this is what I've heard people are naming the wiring & ecu type for 01+ Honda's (ie. Civic & RSX). It's actually still OBD2 but a another (new) version of it. It's probably better to call it OBD2C.

 

thanks, that sounds pretty tricky. but yeah now i see why sticking to your OBD type is alot easier. well one of my friends said that this dude he knows with a civic 88-91 switched his OBD to like OBD1 i'm guessing since thats the next type up but, either way they said it was "japanese" instead of american. would there be any benefits from that??? they told me it gave him a couple extra horsepower and i was thinking how the heck do you get some extra horsepower from re-wiring a little 12 volt car wiring system???

oh yah forgot about that...

Yeah, for the older OBD civic/integra's, mainly 88-91's, there are jumper harnesses available that allow you to convert to OBD1. And its true, you can benefit from converting to OBD1 in these vehicles. Reasonbeing is OBD1 has a better ignition system (distributor) and overall ECU + ECU programming. Its not so much a conversion of 12 volt electricity, but the programming and ignition output that OBD owners can benefit from converting to OBD1.

When this conversion takes place, its best if the vehicle has MPFi (multi point fuel injection - found on Si models) or has converted to MPFi, and not DPFi (dual point fuel injection - lower end models). Parts needed are OBD1 distributor + both female & male distributor plugs, OBD1 injectors (but not manditory), and OBD1 4-wire 02 sensor. The user would keep their existing OBD engine wire harness and modify it by color matching and splicing in the OBD1 distr. plugs in the place of the OBD distr. plugs; and then wiring in the 4-wire 02 sensor directly to the jumper harness.

Also, owners of OBD2 vehicles convert to OBD1 as well, because OBD1 ecu's are easier to have reprogrammed than OBD2 ecu's.

 

wow, your knowledge is vast, truly your are a honda-tech.
