1) learn some grammar, it took me an hour to read that
2) what is your Q exactly? if u can see the #s on the block and head, then why don't u know what engine u have? are u just asking bc ur vc is different?

also check the serial number below the engine code stamp
usually OBD0 Blocks start with a 1
and OBD1 blocks start with a 5

 

thanks to D16siHatch thats helpful and it does start with a 5 but the dizzy and the ecu r obd0 , And to 00siboy i didnt come on here asking for u to talk about grammer but thanks anyways and im asking what motor do i have i order a 1st gen and it looks like a 2nd gen and its looking like the numbers r adding up to it being a 2nd gen thats what im asking can u under stand that or u need more ?

thanks man

 

any one ?

 

The motor and head seem to be a 2nd gen one. You can use the OBD-0 distributor and a PW0 or PR3 OBD-0 b16 ECU and it will be fine.

If you are ordering parts, I have a stock 1st gen b16a and I always order parts from a 95-96 (I believe)Del Sol with the b16a3 or a 99-00 Civic Si with the b16a2 in it. All the parts fit, you just have to watch on ordering stuff for your transmission.

 

no thats the way it came to me as obd0 dizzy was on there and came with a pr3 ecu obd0

 

i laughed for about 10 minutes

 

well people what is it a 2nd gen or a 1st gen come on, i payed for a 1st gen and im thinking i got lucky and got a 2nd gen

 

if u paid for a first gen and got a second gen u came up they are just running it obdo all u would have to do is swap dizzzzys n ecu to run it obd1 sheesh

 

You can see for sure which gen the head is by looking at this picture:




No one is going to be able to say about the block as there are people that have 99-00 b16a2's that have 5 million stamp as well. So just consider yourself lucky if you got a gen 2 instead. I mean you make out either way, it's not like you paid for the gen2 but ended up getting a gen 1. The only difference is ~10 hp due to the compression ratio being SLIGHTLY higher (10.4:1 as opposed to 10.2:1 in the first gen)
