If I can recall the 91 Integra LS motors are differen't from the 94-01 Integra LS motors. The 90-91 Integra LS motors are 1.7 liters and the 94-01 are 1.8L.

 

Driver side mount is different.

Thermostat housing is different.

Slight differences in the heads but not enough to care about IMHO if you're going to boost.

 

well 91 is obd0 and 94 is obd1

the b18a from the 91 is a 1.8ltr hence i being called b18(the 92-93 gsr is the 1.7ltr using the b17)

the only difference between the older and newer is the valvetrain. 10 more hp and redlines to 6.8k instead of the old 6.5k, not much of a difference at all

WRONG. Don't spread misinformation.

WRONG. The B18B ECU [OBD1 P75] Redlines at 7200, the B18A ECU redlines at 6800.

 

ok well since i didnt say anything about the ECU lets assume i was just talking about the tach. by reading his I decided not to get to tech. I would have to say that we are both indeed correct

 

Uhm, the ECU is what limits the RPM's...the Tachometer is just a visualization. Either way the A1's are redlined at 6800 and the B1's are redlined at 7200, but I take my A1 to 7200 occasionally with no problems.
