Recently paid a shop to change a cracked timing housing on my wifes 1995 GA. He reused the old tensioner and it jumped six teeth on the crank sprocket leaving me with empty pockets and 16 funny looking valves. Not wanting to get burned again I happened to have an 89 quad4 086 cylinder head(I assume it is an 086) it had factory headers and I utilized the headers, downpipe, and thermostat housing from the 89 block. After a huge amount of time and effort I finished her car with wonderful power gains. VERY NOTICEABLE! I drove the car for a couple of days before I let my wife and kids loose in it. And it developed a rod bearing knock. SO MUCH FOR TRYING!
ANYWAYS~now I am looking to swap engines and being the oddball 95 vin d has gotten on my badside, I want to place a 2.4 twin cam in the car. Everything(Intake, Headers, front mount, and so forth) are going to work just fine and I am fully convinced my ecm will work for the project IF! the spark reference angle for the crankshaft position sensor is the same as a 95 2.3 block. Does anyone happen to know if the reference angles are the same for a 95 2.3 and 96up 2.4.
Here is the only thing I've learned to this point.....
"The crank sensor has moved twice in the block: first in ’89 (making the ’88 crank an oddball) and again in ’95. This means that the reference angle on the crank itself has also changed, and you’ll need to either play with engine calibrations and change the spark reference angle, or else bias your spark advance. The 2.4L crank trigger wheel, incidentally, is wider but smaller in diameter. Wide-open throttle spark advance above 4,000 rpm should be set between 22–24 degrees" ....got that while searching the web. Any further knowledge will put me beyond the laymen on this subject, and will be appreciated. Sorry about the length of the post.
