List your year make model. Alternator, injectors, distributor will not plug and play. You'll have to wire up VTEC, knock and IABs. Depends on your state emissions whether an obd1 or obd2 ECU will pass. Don't buy a VTEC controller.

Re: obd1 to obd2

you can either change the injectors or do what I did and buy the adapter harnesses from rywire. you'll have to get a diff alternator. and I'm pretty sure rywire sells a Vtec sub harness too. just need to pin it to your ecu plug.
