Steve at hmo told me I'd be receiving a 90-91 ZC for my CRX and when I got it 89 was stamped on the block so I called him and asked him about it and he told me all honda blocks are stamped one year behind.. so I really got a 90 motor. I thought he was feeding me some bullshit at first but then I checked my 91 Si motor and its stamped 90.

WTF is up with this.. is everyones like this?

Kamin

yes
its because the engine is made before the car its put into.

drjondurst

its just like, you know how u can buy a 2004 civic in like 2 months, even though its still 2003, they manufacture the cars early, and the date stamped on the block is date of manufacture.

The heads are usually stamped one year behind, but the longblock still shows what year/generation it is for that year car.

so if 96 was stamped on the block would it be obd1 or obd2?

Kamin

should be obdII
it would be out of a 97

but it IS possible for same year stamps.

exactly kamin! alot of time they have early model and late model same year cars, also they usually make minor changes in between.

yes the heads are made and stamped 1 year before the year of the car itself.
so an 89 head/motor is from a 90 chassis.

err I meant 95 im a little slow but I guess it would be obd2..thanks
