I was just wondering if ther was any diffrence between A 1993 B18b and the 1994 through 2001 B18b.Because im looking for a few parts and ther only listing 1994 and up parts.
Thanks

 

I don't recall any difference in the motor itself.....maybe the sensors as through the years it did go from....OBD1 to OBD2a to OBD2b. What parts are you looking for?

 

I came across this little problem looking for an aftermarket Header.Im picking the motor up this weekend from a friend who i bought it off of all i need is a header and clutch.

 

what problem did you run into?

 

Just that I wasn't sure if the header from a 1993 ls and 1994 and up ls were compatable.
Also i keep seeing the abreveation Da what is that ex. Da integra,or Da GSR
Thanks

 

DA is the main part of your chassis code located on your vin number. My friend with a 90-93 body style GS that starts off like JHDA9 yadda yadda yadda...... mine reads JHDC4. My teg is a 96. If your vin number starts off with a number then it will mean either :

if it starts off with a 1 = made in the U.S 2 = made in Canada 3 = made in Mexico ( though I have yet to see an acura with a vin start with a 3 )

a 93 ls (B18a1) fitting on a 94 LS (B18B1 )? Good question. I want to say yes because of the fact that I really don't see why honda would have spent extra money on producing even a slightly different shaped block or putting on a different oil pan on practically the same motor ( but they did put different valve covers is the least that I noticed aside from certain sensor placements ). With anything mass produced, companies will usually resort to the most cost efficient ways of doing stuff. But....if that's not the case then I'm sure someone will chime in here. If not I'll be looking into it in the mean-time.

 

The B18A and B18B are basically the same, there are some minor differences in cams, emissions, locations of sensors, intake manifold, etc. Any 1.8L b-series header will bolt on to any other 1.8L b-series head - whether it's a gsr/itr/ls/gs/se/rs.

If you have a 93 Integra LS with a B18A, you can use a 94-01 LS header without any issues, except maybe having to change your exhaust b-pipe length slightly. The most important thing is that a 92-93 header will have the same o2 location (obd1) as the 94-01 LS header and 00-01 Gsr header. If you used a 90-91 obd0 header, the o2 is located on one of the runners and you would need to do some creative things with the wiring. Also, if you are looking to get a 4-1 header, you will have to notch the crossmember and will have very little clearance if your car is lowered.

DA9 is the chassis code for 2 door Integra RS/LS/LS-S/GS from 90-93, 92-93 GSRs are DB2. But for some reason, the short hand for 2nd gen tegs remains 'DA'.

thank you for clarifying

 

The header and clutch will fit any of the 90-01 ENGINES, but the length of the header will be different at the bottom. So if you are using a 93 integra(DA) engine on a 94 Integra(DC) body, you may have trouble with the cat and exhaust matching up with the header under the car.

As for the clutch, all the cable actuated B18,B16 clutches are interchangeable and all the hydraulic clutches are interchangeable. BUT if you use an originally cable actuated transmission converted to hydraulic use in a newer body or vice versa just use the same clutch that was originally used in the transmission NOT the chassis.
Good luck.

By the way, basically all the parts from the B18B are the same from 92-95. These are all OBD1. 90-91 were B18A, preOBD, and 96-01 are OBD2 with some additional sensors.
Good luck.
