Hey I was just wondering what the difference is in the 8th digit of the vin # is. I know D is 2.3 OHC and T is 2.4 ohc. My car is a 99 cavalier z24, and i found a block with low mileage that I am thinking of picking up, as long as they match up. the block is from a 99 sunfire gt. its 8th 9th and 10th digits are T,9,X. and my 8th 9th and 10th are : D,X,X. Which is weird because I have a 2.4, and D should mean 2.3 right? Im just a bit confused. Can anyone help?

What is the 10th digit of your vin?

1995 was the only year that a 2.3L was in a 3rd gen J. From 1996 to 2002 ALL of the Z/24s and GTs came with the 2.4L(LD9). I believe during the 96 - 02 time line GM did make a few subtle changes to the 2.4L(I believe they added EGR).

Im a eco guy so im not too keen on the specifics of the Quad-4.

But if your just looking for a block to build up, it should be fine.

4-8 th digit is the cars body style(ex. coupe or sedan), engine size, and type( gas or deisel)
9th digit is just the check digit that dont mean anything really
10th is you car YEAR


your X is the year of your car which is 1999

all 2.4s are Ts none of them were Ds i think theres something fish about yout VINyou sure you counted right goin across

post up you VIN (don't post the last 6 digits we don't need those)

TXX would be a 99 2.4
but a DXX would be a 99 2.3 (which never happened in 99)
