92 teg is a b18a1 obd1...we swapped in a b20b and converted the b20b to obd1 and ran it on the auto ecu for about 2 days then accidently we fried the ecu so we are just going to source a manual one to keep the rev limit at 6900...I think the auto redline is like 6200 can't remember now and can't check either lol.
