ok so i bought this ek 99-00 it's manual windows no sunroof ...
so it has a block and tranny but the head was taken off and the block is garbage
it broke a rod so am plannin to put another single in it but i was reading and
heard that i just cant put any single in it ...

i know it has to be an obd2 so it could be plug and play but which d serie codes are obd2
like how do i know if the motor is an obd2 ?

and as long as the motor is obd2 it can plug and play ? i belive the block in it now is a y8

 

The stock 99-00 ECU is OBD2b, so I think plug and play would be a 99-00 D16Y8 engine that came from a manual transmission Civic.

 

so i can only use a y8 engine ??

 

What was the trim of 99-00 Civic (CX, DX, HX, EX, Si)?

 

am not excatly sure ... but i can tell yuh no sunroof and manual windows ... so
that takes out ex as far as i know and si deff aint ...

 

If the car originally had a D16Y8 from the factory it would be a coupe or sedan with a moonroof and power doors (locks, windows).

You can figure out what trim the car is by checking the 4-6 VIN digits.

EJ6 - D16Y7 (1.6L SOHC) (2/3/4 door)
EJ7 - D16Y5 (1.6L SOHC VTEC-E) (2 door)
EJ8 - D16Y8 (1.6L SOHC VTEC) (2/4 door)
EM1 - B16A2 (1.6L DOHC VTEC) (2 door)
EN1 - D16B5 (1.6L SOHC VTEC Compressed Natural Gas) (4 door)

 

the motor is a y7 i checked it out ... so am guessin it's an ej6

 

If you check your VIN you can figure it out.

In fact, if you PM me your full VIN I'll tell you exactly what it is. Trim level and all.
