that second pic is not the ECU... that is the seatbelt control module
you need to pull back the carpet just in front of that module and the ECU is going to be behind a kick plate under that carpet in the passenger floorpan.
Also that Vlave cover is not a V-Tec cover.. looks like a standard B18a1 cover which would indicate you may have an ODB0 car... the DIstributor looks like an ODB1 distributor as the coil point is not straight up and down like the ODB0 distributor... with that ODB1 distributor your timing is off a bit and probably set to be off.
If you want to go Vtec with that block do it, but you are oing to have to do what Talon & others ave said... you will need to upgrade ECU, IM, Distributor, harness to go LS/Vtec, then go get your car tuned to boot.
