I dont remember the date for the 2nd gen when they made changes to the engine, but are there any ways to tell when mine was made? there is no part number on my knock sensor, and i need to know which 2nd gen knock sensor to get from toyota. otherwise i HAVE to use this GM one from ATS.

well from what i've read on alltrac.net the 90-91 has 7 bolts on the exhaust manifold and the 92-93 has 8 or 9. also if u can give me the ecu part number that came with the motor i can tell you exactly what year alltrac it came from.

i have the jdm MR2 engine. i dont know if it makes a difference. as far as i can tell, it has 7 bolts.

then its probably a 91-92, maybe early 93, mr2 3sgte...something like that

bboy

the split was in 92, 7 bolts are 91-92 9 bolts are 93+

basically what bboy said already, but just thought id clarify about when the splut was

ok but i think the date was in June where there was a change in the 2nd gen...the first half of '92 and the second half of '92 had differences. what are the differences that will tell me what month my engine was made in '92. thats what i need to know in order to get the right knock sensor for the '92 engine.

if you have a 7 bolts on your exhaust manifold your engine was made before the june

if you have 9 bolts on your exhaust manifold your engine was made after june.

count the bolts that attatch your manifold to the block. that will give you the answer.

cool i just wanted to clarify that
